Explanation:

Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.

Explaination: Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.

Answer:

Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.

Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.

Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.

Answer:

The correct answer is - A. phototropic and gravitropic.

Explanation:

A plant seedling grows usually two-direction shoots or stems towards light and roots towards the soil or in the direction of gravity. The movement of the plant toward a specific stimulus or effect parts is called tropism and different parts move in a different direction.

The movement of the roots of the plant is usually towards the direction of soil or gravity and this is called gravitropic. The shoot or stem grows from the seedling towards the direction of light and it is called phototropic.

Answer:

A, B, D.

Explanation:

Answer:

186

Explanation:

The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130  bp + (14 bp x 4) = 130 + 56 = 186.

When a small square is sectioned off for study and the plants, animals, and other organisms in that section are counted, the study is called a quadrat sampling.

Quadrat sampling is also referred to as quadrat study. In ecological research, it is a method used to determine the number or density of organisms in a certain specific area.

It involves dividing the study area into smaller, equally sized plots or squares called quadrats. The size of the quadrat depends on the organisms being studied and the scale of the research.

Answer:

There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection. After a while the birds will get old and their beaks will get weaker, eventually they will die, when there is a shortage of food they will start harming each other in order for it, that’s selection.

Northern blotting is the least likely to be used in identifying transcription factor binding sites. Therefore, option "B" is correct. Northern blotting is used for the analysis of RNA in the given sample. The samples can be tissue, blood, and serum.

The RNA is purified from the given sample. The sample might contain fragmented RNA which is purified and amplified. The target RNA is separated by using an electric current. The RNA moved through the gel which act like a sieve-like matrix. The movement of the fragments depends on the size of the fragments. Smaller fragments move faster than larger ones in Northern blotting.

According to Tinbergen, if you are examining a trait to determine how it contributes to the survival and reproduction of an organism, you are studying the trait's adaptive value or fitness.

Niko Tinbergen was a renowned ethologist who proposed four questions to understand behavior in animals, including the study of traits. One of these questions pertains to the adaptive value or fitness of a trait, which focuses on how the trait affects the survival and reproduction of an organism.

By examining the trait's contribution to an organism's ability to survive in its environment and successfully reproduce, researchers can gain insights into the evolutionary significance of the trait. This approach helps in understanding the selective pressures that have shaped the trait over time, as traits that enhance survival and reproduction are more likely to be favored by natural selection.

Small habitat such as a tree stump that contains its own ecosystem is not a characteristic of biome.

A biome is a large geographic region on Earth that is characterized by a specific set of climatic and environmental conditions, as well as a distinctive community of plants and animals. Biomes are defined by their dominant vegetation, which is adapted to the specific climate and environmental factors of the region. There are several different types of biomes, including forests, grasslands, tundra, deserts, and aquatic biomes such as oceans and freshwater ecosystems. Biomes are important for maintaining biodiversity and ecological balance, and are also valuable for human use, providing resources such as timber, food, and water. The study of biomes is an important aspect of ecology, and helps us understand how living organisms interact with their environment.

c) Small habitat such as a tree stump that contains its own ecosystem. The other options are all characteristics of a biome. Biomes are large areas of the Earth that have similar climates and organisms, and are characterized by the same plant and animal communities. Biomes are typically defined by their predominant vegetation type and are classified based on factors such as temperature, precipitation, and soil type. Therefore, option C is the correct answer.

The genetic material in each daughter cell is identical to that in the parent cell, and the process of mitosis ensures that each daughter cell receives a copy of each chromosome.

a. The process represented here is cell division. b. The reasons why this process is cell division are:
1. The parent cell is dividing into two daughter cells.
2. The daughter cells are genetically identical to each other. c. The parent cell is a somatic cell. It is not a gamete because gametes are produced by meiosis, not mitosis. d. The end result of this process is two genetically identical daughter cells. e. The daughter cells are genetically identical to each other. They are the same because they are produced by mitosis, which involves only one round of cell division and results in two daughter cells that are genetically identical to each other. The genetic material in each daughter cell is identical to that in the parent cell, and the process of mitosis ensures that each daughter cell receives a copy of each chromosome.
