Which is one event that may lead to Primary succession? clear-cutting climate change volcanic eruption introduced species
Answer:
Primary Succession is when an uninhabited area becomes an ecosystem, and Secondary secession is when an ecosystem is destroyed an Independent factor, like a fire, a hurricane, stuff like that.
Explanation:
Clear-cutting climate change would be an example of Secondary Secession, and volcanic eruption introduced species would be an example of Primary Secession.
Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time.
The event that may lead to Primary succession is: volcanic eruption
What are the three causes of primary succession?The main causes of ecological succession include the biotic and climatic factors that can destroy the populations of an area. Wind, fire, soil erosion and natural disasters include the climatic factors.
What organisms come first after a volcanic eruption then what happens?Lava from a volcanic eruption hardens into bare rock. Primary succession begins with soil formation. The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens.

2. DESERT A desert is an area of the earth's surface totally or almost totally uninhabited. A desert can be a sandy or stony terrain that lacks vegetation due to low rainfall. The harsh environmental conditions mean that these deserts have little stable population DELGADO ELERA, REYNER. CHARACTERISTICS OF THE DESERTS. Temperatures are generally high, but nights can be cold. Its climate is extreme with temperatures of 50 ° C during the day and –20 ° C at night. It is the ecosystem that presents water scarcity. The ground is covered with sand as a result of the disintegration of rocks. The relief presents plains, dunes and in some places oases. There are counter winds and rains are very scarce. Deserts form the largest area of the earth's surface. BIOTIC AND ABIOTIC FACTORS THAT INFLUENCE DESERT BIOMA BIOTIC FACTORS THAT INFLUENCE DESERT BIOME These are the living beings of an ecosystem that survive. They can refer to the flora, fauna, humans of a place and their interactions. Individuals must have specific behavior and physiological characteristics that allow their survival and reproduction in a defined environment. The condition of sharing an environment engenders a competition between species, given by food, space, etc. Depending on the region: In the desert only some animals manage to survive: camels, lizards, spiders, owls, rats, kangaroo, mice, a variety of snakes, hawks, scorpions, birds, squirrels among others. In the same way, in the fauna, only some plants manage to survive. These protect themselves from other animals with the thorns they have and with their thick layer of skin, some of them are: cactus, palm trees, nopales, bushes, grasslands, weeds in oases, etc.
3. Plants and animals that live in the desert are conditioned to withstand extreme temperatures with minimal water. ABIOTIC FACTORS THAT INFLUENCE DESERT BIOME Abiotic means lifeless. They are the different components that determine the physical space in which living beings inhabit; among the most important we can find water, temperature, light, soil, humidity, air and nutrients. They are the lifeless factors. Deserts are known for their extreme abiotic factors. Varied temperature and scarce fluvial precipitation. Sunlight, climatic factors such as: humidity (very low) and temperature (high during the day, very low at night); rocks, sand or very dry soil, atmospheric gases, very strong barometric pressure. Rocky terrain, wind processes are important factors in the formation of the landscape. They have an average rainfall of 200 to 500 mm per year. MOST REPRESENTATIVE DESERTS OF PERU 1. DESERT OF SECHURA One of the most representative deserts of Peru is that of Sechura, located in the northwest of Peru, just between the Lambayeque and Piura regions having a length of 150 kilometers by a width of 100. It is located 55 km southwest of the city of Piura. It is the widest area of the coastal desert in Peru, it has an area of more than 5000 square km. This desert is an arid plateau formed by materials from the Tertiary, with little vegetation, which includes several intermittent lagoons. The aridity of the climate and the unproductive soils limit the settlement of the population, except in the oases that constitute the mouths of the Piura rivers, to the north, and Lambayeque, to the south; agriculture is possible in these areas.

6. List and describe 8 part of prokaryote cells.
Answer:
Prokaryotes explanation
Explanation:
Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth. As organized in the Three Domain System, prokaryotes include bacteria and archaeans. Some prokaryotes, such as cyanobacteria, are photosynthetic organisms and are capable of photosynthesis.
Many prokaryotes are extremophiles and can live and thrive in various types of extreme environments including hydrothermal vents, hot springs, swamps, wetlands, and the guts of humans and animals (Helicobacter pylori).
Prokaryotic bacteria can be found almost anywhere and are part of the human microbiota. They live on your skin, in your body, and on everyday objects in your environment.
Prokaryotic Cell Structure
Bacterial Cell Structure
Bacterial Cell Anatomy and Internal Structure. Jack0m/Getty Images
Prokaryotic cells are not as complex as eukaryotic cells. They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid.
Prokaryotic organisms have varying cell shapes. The most common bacteria shapes are spherical, rod-shaped, and spiral.
Using bacteria as our sample prokaryote, the following structures and organelles can be found in bacterial cells:
Capsule: Found in some bacterial cells, this additional outer covering protects the cell when it is engulfed by other organisms, assists in retaining moisture, and helps the cell adhere to surfaces and nutrients.
Cell Wall: The cell wall is an outer covering that protects the bacterial cell and gives it shape.
Cytoplasm: Cytoplasm is a gel-like substance composed mainly of water that also contains enzymes, salts, cell components, and various organic molecules.
Cell Membrane or Plasma Membrane: The cell membrane surrounds the cell's cytoplasm and regulates the flow of substances in and out of the cell.
Pili (Pilus singular): Hair-like structures on the surface of the cell that attach to other bacterial cells. Shorter pili called fimbriae help bacteria attach to surfaces.
Flagella: Flagella are long, whip-like protrusions that aid in cellular locomotion.
Ribosomes: Ribosomes are cell structures responsible for protein production.
Plasmids: Plasmids are gene-carrying, circular DNA structures that are not involved in reproduction.
Nucleoid Region: Area of the cytoplasm that contains the single bacterial DNA molecule.
Prokaryotic cells lack organelles found in eukaryoitic cells such as mitochondria, endoplasmic reticuli, and Golgi complexes. According to the Endosymbiotic Theory, eukaryotic organelles are thought to have evolved from prokaryotic cells living in endosymbiotic relationships with one another.
Like plant cells, bacteria have a cell wall. Some bacteria also have a polysaccharide capsule layer surrounding the cell wall. This is the layer where bacteria produce biofilm, a slimy substance that helps bacterial colonies adhere to surfaces and to each other for protection against antibiotics, chemicals, and other hazardous substances.
Similar to plants and algae, some prokaryotes also have photosynthetic pigments. These light-absorbing pigments enable photosynthetic bacteria to obtain nutrition from light.
Binary Fission
E. coli Bacterium Binary Fission.
E. coli bacteria undergoing binary fission. The cell wall is dividing resulting in the formation of two cells. Janice Carr/CDC
Most prokaryotes reproduce asexually through a process called binary fission. During binary fission, the single DNA molecule replicates and the original cell is divided into two identical cells.
Steps of Binary Fission
Binary fission begins with DNA replication of the single DNA molecule. Both copies of DNA attach to the cell membrane.
Next, the cell membrane begins to grow between the two DNA molecules. Once the bacterium just about doubles its original size, the cell membrane begins to pinch inward.
A cell wall then forms between the two DNA molecules dividing the original cell into two identical daughter cells.
Although E.coli and other bacteria most commonly reproduce by binary fission, this mode of reproduction does not produce genetic variation within the organism.
Prokaryotic Recombination
Bacterial Conjugation

Genetic variation within prokaryotic organisms is accomplished through recombination. In recombination, genes from one prokaryote are incorporated into the genome of another prokaryote.
Recombination is accomplished in bacterial reproduction by the processes of conjugation, transformation, or transduction.
Capsule, cell wall, cell membrane, pilus, flagella, ribosomes, nucleoid, and plasmids are the parts of prokaryotic cells.
What are the parts of prokaryotic cells?Single-celled creatures known as prokaryotes are the earliest and most basic living forms on Earth. Bacteria and archaeans are prokaryotes, which are classified according to the Three Domain System. Some prokaryotes are photosynthetic creatures and can do photosynthesis, such as cyanobacteria.
Prokaryotic bacteria are ubiquitous and comprise a significant portion of the human microbiome. They exist on your skin, inside your body, and on commonplace items in your surroundings.
Bacteria, as a sample prokaryote, its cells have the following organelles and structures:
Capsule: Found in some bacterial cells, this extra outer layer aids in moisture retention, prevents the cell from being swallowed by other organisms, and aids the cell's adherence to surfaces and nutrients.Cell Wall: The bacterial cell's cell wall serves as both a protective barrier and a structural component.The cell membrane: also known as the plasma membrane, protects the cytoplasm of the cell and controls how substances enter and exit the cell.Pili (Pilus singular): Surface-mounted, hair-like structures that connect to other bacterial cells. Fimbriae, which have shorter pili, aid bacterial attachment to surfaces.Flagella: Long, whip-like protrusions called flagella assist cells in moving about.Ribosomes: Ribosomes are the parts of cells that make proteins.Nucleoid: They are the part of the cytoplasmic region that carries a single molecule of bacterial DNA.Cytoplasm: Cytoplasm is an organic material that resembles a gel and is mostly made of water. It also includes enzymes, salts, and numerous cell components.Therefore, the capsule, cell wall, cell membrane, pilus, flagella, ribosomes, nucleoid, and plasmids are the parts of the prokaryotic cells.

The rate of species extinction on Earth is currently very high—perhaps as high as it has been since the time of the dinosaur extinction. Which of the following disruptions is not a major cause of this high extinction rate? a The hunting and overfishing of wildlife b The introduction by humans of invasive species into habitats c The use of animals in scientific research and experiments d The draining and filling of wetlands
Answer:
C. The use of animals in scientific research and experiments.
Explanation:
I got this answer correct when I took it.
The disruption which is not a major cause of a high extinction rate is: C. The use of animals in scientific research and experiments.
Extinction can be defined as a process or situation in which a species, family, or other taxonomic group of living organisms such as animals or plants become extinguished, destroyed, exterminated or dead.
This ultimately implies that, extinction literally means the extermination or dying out of a species, family, or other taxonomic group of living organisms.
Basically, the extinction of living organisms is mainly caused due to the effect of environmental forces and evolutionary changes such as:
Habitat fragmentation.Poor reproduction techniques.Natural disasters.Overexploitation of species by humans such as the hunting and overfishing of wildlife.Genetic inbreeding.An introduction of invasive species into natural habitats by humans.The artificial draining and filling of wetlands.In conclusion, the disruption which isn't a major cause of a high extinction rate is the use of animals or plants in scientific research and experiments because often times they are not killed and only a sample of the population is used.

14. Give an example of three adaptations in polar bears. Be sure to
state how each trait is an adaptation.
Answer:
Adaptations
Explanation:
1). "White" fur- Polar bears are well known for this adaptation, white fur. Their fur is actually clear, but gives the appearance of being white. This is so they can blend into their environment.
2). Fur and fat- They have very thick layers of fur and fat, to help keep them warm(insulate them), as their habitat is extremely cold. This prevents things like hypothermia and frostbite.
3). Large feet- Their feet are quite large, which gives them an advantage. It results in more even, spread out weight distribution, and gives them a better grip on the ice.
Here's an extra:
4). Greasy coat- Polar bears are excellent swimmers, and as a result of their swimming habits, they actually have a greasy coat. This grease is much like oils a duck or goose(or other aquatic aviary species) have. It causes water to roll off of them, meaning they're considered hydrophobic.

You have planted corn in a field with clay soil. The field is predominantly flat with a slight slope at one end where a creek borders the field. You notice that germination and growth is slowest in the flattest portion of the field. Conversely, you also notice that you received good germination and rapid growth on the slight hill which meets the creek. You wonder why there should be differences in growth and germination in different parts of the field. Is it due to the extra water near the creek? Is there something different about the soil in that portion of the field, or is it due to the difference in slope (north, south, east, and west). 1. What is your hypothesis for this problem? 2. Design an experiment to test the hypothesis you have written (make sure you include a procedure [step by step list of what you will do], an IV, a DV, treatments, trials, and constants).
Hypothesis: The soil in the flat part of the field has less fertility than the soil on the small hill.
Experiment:
The experiment will be carried out in a greenhouse, to promote a controlled environment and equal to all plants used in the treatment.
In this experiment, the influence of the difference in fertility of the soil samples, in the flat part of the land and in the most inclined part, in the germination and growth of corn plants will be tested.
Corn seeds of the same species will be selected. All seeds will be sanitized and will go through the same dormancy breaking process, so that all of them have their germination stimulated.
Vessels with a capacity of 30 kilos will be caught. These pots will be cleaned, sterilized and filled with the same amount of soil collected in the field and with two corn seeds. It will be used 10 pots with soil that was collected in the flat part of the land, 10 pots with soil from the sloping part of the land and 10 pots with fertilized substrate containing high levels of fertility.
The pots will be placed in a greenhouse and will be irrigated with distilled water, to avoid contamination by possible substances in the water.
The pots will remain in the greenhouse for 100 days, where the behavior of seeds and plants in each of them will be observed and noted. After this period, a comparison will be made between the vessels of each treatment, assessing the differences between them and reaching the conclusion whether the hypothesis is true or false.
