Answer:
All are macromolecules/polymers, have monomers (though different kinds), and help perform bodily functions.
Advanced Biology answer: All are macromolecules with functional groups that make them function uniquely from each other. Their monomers all have a complex of bonds and atoms that give them shape, helping function.

Which type of cell is being described in the following passage? The cell has a large surface area due to its biconcave shape. It is able to store lots of haemoglobin as it does not have a nucleus.
Answer:
Red blood cell
Explanation:
Red blood cell has a large surface area due to its biconcave shape. It is able to store lots of haemoglobin as it does not have a nucleus.
Red blood cells have the form of a flat disk, resembling a doughnut, that is spherical, has an indentation in the middle, but is not hollow.
What are the different characteristics of Red blood cell?Red blood cells are minuscule. Unlike white blood cells, red blood cells don't have a nucleus, which makes it easier for them to alter shape and circulate around your body.
Red blood cells are disc-shaped, biconcave structures without a nucleus or organelles. Red blood cells' adaptation to transfer gases is visible in their form.
The surface area through which Hades can diffuse is expanded. Additionally, the cell's structure brings oxygen-carrying hemoglobin molecules closer to it.
Therefore, Red blood cell has a large surface area due to its biconcave shape. It is able to store lots of hemoglobin, as it does not have a nucleus.

Which statement best describes trait distribution?
Distribution describes how individuals in a population are spread across their habitat.
Distribution describes how the variation in traits is spread across a population.
Distribution describes the different traits that are found in a species.
Distribution describes the different traits that are found in a population
I will post answer in comments
The statement 'distribution describes the different traits that are found in a population' BEST describes trait distribution. It involves the variation of a phenotypic trait.
Trait distribution refers to the differences among populations in the frequency distributions of the states for a specific phenotypic trait.
Variation of a phenotypic trait in a population is the result of genetic factors and environmental factors and the interaction of these factors.
Heritability of a trait refers to the percentage of variation in a trait that is due to genetic factors.

Suppose a mutation occurs in an individual animal. What do you think would happen if the mutation had these different effects on the animal?
Choose A, B, or C for each effect, and be prepared to explain why you chose that result.
A. The mutation will become more common.
B. The mutation will disappear.
C. The mutation will remain at a low level.
Effect #1: The mutation results in the organism having more offspring.
Effect #2: The mutation confers resistance to a deadly disease.
Effect #3: The mutation results in the organism being less attractive to potential mates.
Effect #4: The mutation produces no change in the animal.
Answer:
For effect #1, the mutation will become more common (A). This is because with the organism having more children, the trait will be passed around much faster and will spread to surrounding groups of animals.
For effect #2, the mutation will become more common (A). This is because the disease will kill the animals who do not carry the gene leaving only the animals with the trait, making it much more common
For effet #3, the mutation will disappear (B). This is because the animal carrying the gene will slowly die off. After all, they will not be able to reproduce and pass the gene to their children.
For effect #4, the mutation will remain at a low level (C). This happens because since it procures no change there will be no reason to transfer it so it will become a recessive trait in the animals.

what is the function of topoisomerase in dna replication?
Answer: Topoisomerases (or DNA topoisomerases) are enzymes that participate in the overwinding or underwinding of DNA. The winding problem of DNA arises due to the intertwined nature of its double-helical structure. During DNA replication and transcription, DNA becomes overwound ahead of a replication fork.

______ is the conversion of one form of energy to another. In biology, it is used to describe the conversion of stimulus energy into an electrical signal in the nervous system.
In Biology, the conversion of an energy form into another form of energy such as the conversion of stimulus energy into an electrical signal in the nervous system of a living organism is referred to as: Transduction.
Energy can be defined as the ability (capacity) of a living organism to do work and it is measured in calories or Joules (J).
Transduction refers to a process through which the signal message contained in the outside of a living cell is converted into a message within or inside the living cell.
On a related note, transduction can be used to describe the conversion of an energy form into another form of energy.
In Biology for instance, the conversion of stimulus energy into an electrical signal in the nervous system of a living organism can be described by using transduction.

In Mendel's experiments, if the gene for tall (T1) plants was incompletely dominant over the gene for short (T2) plants, what would be the result of crossing two T1T2 plants
Answer:
25% would be tall (T1T1), 50% would be intermediate height (T1T2), and 25% would be short (T2T2)
Explanation:
25% would be tall (T1T1), 50% would be of average height (T1T2), and 25% would be under five feet (T2T2).
What is incomplete dominance?When a dominant allele, or form of a gene, does not entirely block the effects of a recessive allele, the resultant physical appearance of the organism reveals a mixing of both alleles. It is sometimes referred to as partial or semi-dominance.
There are two different forms of genetic inheritance, full dominance, and codominance. Codominance basically implies that neither allele is able to suppress or obstruct the expression of the other allele.
The cross between T1T2 X T1T2 is attached in the image below.
However, incomplete dominance occurs when a dominant allele only partially obscures the effects of a recessive gene.

As climate changes because of global warming, plant species' ranges in the northern hemisphere may move northward. The trees that are most likely to avoid extinction in such an environment are those that ________. A. have larger, more contiguous established populations to begin with B. produce well-provisioned seeds C. have seeds that become viable only after a forest fire D. disperse many seeds in close proximity to the parent tree
The trees that are most likely to avoid extinction in such an environment
have seeds that are easily dispersed by wind or animals .
Trees which are easily dispersed by wind or animals have a very high chance of survival because the seeds dispersed will grow to form trees and if there is death of some they will still be present due to the continuous seed dispersal.
This is the main reason why the seeds with more dispersal means will not
become extinct.
