How many alleles are in the gene pool?
Answer:
40 b alleles
Explanation:
Only 40 b alleles are present in the gene pool, so genetic diversity is lower. The use of gene pools allows population geneticists to see variation and the influence of natural selection in detail. A single gene may show significantly less genetic variation than the variation within the whole genome of a population

how did adaptive radiation affect plants after they first moved to land
Explanation:
it gradually stops seed growth and sprouting depending on how much radiation is released.If there is too much evaporation due to intense radiation,the stomata closes to reserve water and if the stomata is unable to open for a long period of time the growth of the plant is stunted.Which shows the levels of organizational hierarchy listed from least complex to most complex?
O population, community, ecosystem
O ecosystem, population, community
O community, population, ecosystem
O community, ecosystem, population
Answer:
I think the answer to this question is O population, community, ecosystem.
Population, community, and ecosystem show the levels of organizational hierarchy from least complex to most complex. Therefore, the correct statement is option A.
What is the community consisting of?A community is made up of all the populations of different species that live in the same area and interact with one another. A population is a group of people from the same species who live there.
A biological system remembers every one of the living organic entities for a local area, as well as the actual climate in which they live and connect. In this order, the population is the most un-complex level, as it alludes to a gathering of people of similar species.
Community is more complicated because it involves interactions between multiple species populations. Because it encompasses all living and nonliving components of an area as well as their interactions, the ecosystem level is the most complex.
Therefore, population, community, and ecosystem show the levels of organizational hierarchy from least complex to most complex.

The surface area of a sphere can be approximated as follows:
Surface area = 411/2;
where ris the radius of the sphere;
Ti is a constant that is roughly equal to 3.
Using the simple approximation above, calculate the surface area of a sphere
with a radius of 5 meters.
A. 500 m2
B. 900 m2
C. 3,600 m2
D. 300 m2
Answer:
D. 300 m²
Explanation:
A sphere is a three dimensional object with a surface which as like that of a ball. A sphere is a set of points that are all at the same distance r from a given point in a three-dimensional space.
The surface area of a sphere is:
Surface area = 4πr²
where r is the radius of the sphere, π is a constant = 3
Given that r = 5 meters, hence substituting into the area equation:
Surface area = 4π(5)² = 4(3)(5)² = 300 m²
According to the author, how has the almond tree
monoculture affected honeybees in Central Valley,
California? What evidence is provided to support the
claim?
I
Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try and help as best I can.
The only way you can answer this question is by reading the text. During this reading, you will notice that there is an element in monoculture that is harming bees, making them have a very difficult life or even die. This element is what is affecting the bees. The author will show why this element is harmful to bees through sentences that prove the effect that this element promotes and how it only exists in monocultures. These sentences will be the text evidence.
It is likely that the author shows how monoculture requires a large use of pesticides, which ends up harming the life of bees. He can also show that monoculture decreases the availability of food for bees, since all monoculture plants only flower once a year and leave the bees without food for the rest of the year, as there is no plant diversity in the monoculture.
Answer:
sample response
Explanation:
Because of the growth of the almond trees, many honeybees have died. Honeybees do not naturally live near the trees so they are transported to the area in order to pollinate the trees. However, the bees are exposed to pesticides that are used on the trees. Many also likely die because the almond trees only bloom in February, so the bees do not have enough food for the rest of the year.

Which set of ecological organization levels is most likely to contain the largest variety of species?
1.
multiple biomes in a biosphere
2.
multiple ecosystems in a biome
3.
3
multiple individuals in a population
4.

The set of ecological organization levels that is most likely to contain the largest variety of species is: multiple biomes in a biosphere.
LEVEL OF ECOLOGICAL ORGANIZATION:
Ecology refers to the study of plants and animals (biotic) in relation to their environment. The level of organization in an ecological setup involves an hierarchical build up. The level of organization in ecology from the least to the highest is as follows: individual species → population → community → ecosystem → biome → biosphere. As the level increases, the more the species contained. This means that a community will contain more species than a population. Therefore, the largest variety of species is most likely to be found in the highest level of organization, which is multiple biomes in a biosphere.Learn more at: https://brainly.com/question/18536684?referrer=searchResults

Which is an example of why the process of photosynthesis is important to life on Earth?- - Grass uses photosynthesis to produce glucose, which is used within the grass for growth.
- Fungi use photosynthesis to decompose dead and decaying plant matter.
- Ectothermic animals use photosynthesis to convert sunlight into energy for cell functions.
- Green plants use photosynthesis to remove oxygen gas from the atmosphere and replenish the earth’s carbon dioxide.
Answer:
The correct answer is: A) Grass uses photosynthesis to produce glucose, which is used within the grass for growth.
Explanation:
Photosynthesis is the process by which green plants, which include algae, take in the energy from the sun and combines it with carbon dioxide (and water) to form benificial sugars.
Photosynthesis refers to the process by which the green plants, as well as algae, utilize the energy from the sun in combination with the carbon dioxide as well as water to form simple sugars. This is how the harmful gas carbion dioxide can be destroyed and elimanated.
