what is evolutionary mechanism?

pls help>-<

Answers

Answer:

Evolutionary mechanism refers to the changes in allele frequencies within a single population.

a population of white moths lives in a forest near a factory. this factory burns coal and pollutes the air with black dust. over time, this dust has settled on the trees in the area, making them darker in color. this could result in
1. an increase in the white moth population.
2. a decrease in the white moth population
3. an increase in the number of trees in the area
4. a decrease in the air pollution affecting the area

Answers

The answer to your question is option b

This is because if the trees are black, and covered with soot due to the pollution, caused by industrialisation, the white moths will be easily seen and constantly hunted by the predator, compared with the black moth population as they camouflage easily. Ultimately, the white moths would be hunted to such an extent that their population would dramatically decrease

Use the rose experiment to answer the question. What are the independent and dependent variables?

Answers

Answer:

Independent Variable - Amount of Light;

Dependent Variable - Plant Growth;

Controlled Variables - temperature, soil, container, and humidity

Explanation:

Independent Variable - Amount of Light;

Dependent Variable - Plant Growth;

Controlled Variables - temperature, soil, container, and humidity

1. Plants need light for it growth and development. By studying photosynthesis and chlorophyll one can  recognizes two factors: measure of light and development of a plant.  

The adjustment in light influences the development of a plant. Both the two factors are measurable.  

Cause-Independent Variable: measure of light  

Impact Dependent Variable: development of plant  

2. Plants have stems that become upward and roots that become descending. Become familiar with geotropism.  

Answer:

The rose experiment is not a specific experiment but refers to a general example used to explain the concept of variables in an experiment. In this example, let's say we want to study the effect of fertilizer on the growth of roses.

The independent variable in this experiment is the fertilizer. It is the variable that is manipulated or changed by the experimenter. In other words, the experimenter decides how much fertilizer to apply to each group of roses.

The dependent variable in this experiment is the growth of the roses. It is the variable that is being measured and affected by the independent variable. In this case, the experimenter measures the height, number of leaves, and number of flowers for each group of roses, and this data is used to determine if the fertilizer had any effect on the growth of the roses.

Therefore, in the rose experiment, the independent variable is the amount of fertilizer applied to each group of roses, and the dependent variable is the growth of the roses, measured by their height, number of leaves, and number of flowers.

The interconnections of the cardiovascular system with each of the other major body systems is of the utmost importance for the health of the human body. The circulatory system's main function is to take blood to all the cells of our body.

Someone expressing a recessive hair color has _______.
A-1 dominant and 1 recessive allele for hair color
B-2 dominant alleles for hair color
C-2 recessive alleles for hair color

Answers

Answer: The answer would be C

Explanation: This is because in order to express a recessive trait one must have no dominant alleles or otherwise the dominant would win out and be expressed instead. For example, if a person had 1 allele for brown hair and 1  for red the brown would win and the same would happen if they had 2 brown hair alleles. Whereas if a person had two alleles for red hair and none for brown, only then would the red trait be expressed. Hope this helped!
