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.Why would it be important to understand what controls the number and types

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

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

Also, what would be some real world applications to the importance of the properties of water?
Please make sure to answer all of the questions within this one, for any clarification needed it is basically a lab report on how surface tension is effected by the temperature of water. Please answer and Thank you!
Answer: The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.
Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it! Water has high heat capacity.

Select three examples of resistance to antibiotics that is due to an altered cellular target of the drug. Multiple select question. The activity of beta-lactamase Addition of acetyl-CoA to chloramphenicol Alteration of an enzyme involved in folic acid synthesis A change in the structure of 23S rRNA The terminal D-alanine of pentapeptide mutates to D-serine
Answer:
- Alteration of an enzyme involved in folic acid synthesis
- A change in the structure of 23S rRNA
- The terminal D-alanine of pentapeptide mutates to D-serine
Explanation:
Antibiotic resistance is the phenomenon by which microorganisms naturally have, acquire, or develop the ability to defeat the drugs designed to eliminate them. For example, trimethoprim is able to bind with the enzyme dihydrofolate reductase (DHFR) in order to inhibit the folic acid synthesis pathway. Sulfonamides (sulfa drugs) competitively inhibit the incorporation of para-aminobenzoic acid (PABA) into folic acid and thus also prevent the synthesis of folic acid. Ribosomes are organelles where proteins are synthesized. The 23S rRNA is a component of the large subunit (50S) of bacteria and archaea ribosomes. In consequence, it is expected that a modification in the structure of 23S rRNA alters protein synthesis. Finally, vancomycin acts by binding the terminal D-Ala-D-Ala residues of the polymeric lipid-PP-disaccharide-pentapeptides and thus inhibits cell wall synthesis in Gram-positive bacteria. In consequence, it is expected that a mutation at the terminal D-alanine that modifies this sequence alters the vancomycin binding site and thus also confers antibiotic resistance.
What makes up the "head" region of a phospholipid? __________Is it hydrophobic or hydrophilic?_________
Answer:
Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.

10.What is holozoic nutrition?
Answer:
1. Digestion helps to break down the food into simple, soluble form.
2. Name the process by which absorbed nutrients are utilized by the body?
Ans. Assimilation is the process by which absorbed nutrients are utilized by the body.
3. Where does initial digestion of protein take place?
Ans. Mechanical digestion of protein begins in the mouth and continues in the stomach and small intestine. Chemical digestion of protein begins in the stomach and ends in the small intestine. The body recycles amino acids to make more proteins.
4. Where is the water absorbed from undigested food in the digestive system?
Ans. Water from the undigested food is absorbed mainly in the large intestine.
5. Name one animal that lives on liquid food only.
Ans. Mosquito lives on liquid food only. They rely on human blood for their food.
6. The process of taking in food into the human body is called ingestion.
Ans. True.
7. The alimentary canal stretches from mouth to anus.
8. What is rumen?
Ans. Rumen is the largest compartment of the stomach of a ruminant in which cellulose is broken down by the action of symbiotic microorganisms. The primary function of the rumen is as a storage compartment to facilitate microbial (bacterial and protozoal) fermentation of ingesta.
9. Which animals are called ruminant?
Ans. Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach, they have four. Of the four compartments, the rumen is the largest section and the main digestive centre.
10.What is holozoic nutrition?
Ans. Holozoic nutrition is a method of nutrition that involves the ingestion of some complex organic substances that may be in the solid or the liquid state.
Mendel determined from his pea plant experiments that some copies of genes are dominant while others are recessive. Explain how two tall plants could produce a short plant.
describe how alleles and genes are created
Answer:
Look at explanation
Explanation:
An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homo-zygous for that gene. If the alleles are different, the individual is hetero-zygous.

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 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.
