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.

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.

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.
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.

The largest known protein with the greatest number of amino acids is titin.
What is titin ?Titin or connectin is a largest protein in humans which is encoded by the TTN gene, having greater than 1 µm in length and it functions as a molecular spring responsible for the passive elasticity of muscle.
It consist of 244 folded protein domains connected by unstructured peptide sequences, when the protein is stretched, the domains will unfold.
Titin protein involve in the contraction of striated muscle and connected the Z line to the M line in the sarcomere, contributes to force transmission at the Z line.
It limits the motion range of the sarcomere during tension, so it involve in the contribution of passive stiffness of muscle, it is the third most abundant protein in muscle after myosin and actin.
