The small population of mastering the beetles will most likely lead to genetic drift. This drift could have an impact on the allele frequency, and a decrease in genetic diversity. As a result, the gene pool will become less variable.


If a small population of mastering the beetles is discovered, genetic drift is likely to occur. Due to random changes in the gene pool, the frequency of the brown or green allele will change. The gene pool's variability will decrease as a result of genetic drift. Due to a small population, alleles are more likely to be lost. Genetic drift has a significant impact on small populations, as it leads to the reduction of genetic variation, an increase in genetic differentiation, and an increase in the frequency of detrimental alleles. In such a population, the genetic makeup will change and lead to decreased genetic diversity.

Gran Dolina adult hominids were similar to later Homo sapiens in their large cranial capacity. The correct option is b.

Cranial capacity is a measure of the volume of the braincase, and it is an important indicator of brain size and complexity. The Gran Dolina hominids had a cranial capacity of around 1000 cubic centimeters, which is similar to that of early Homo sapiens and other hominid species that lived later in time.

While there is no evidence to suggest that Gran Dolina hominids produced art, and their nasal aperture size is not particularly significant in terms of their similarity to Homo sapiens, their cranial capacity is an important characteristic that links them to our own species. A larger brain size is generally associated with higher cognitive abilities and more advanced tool-making techniques, both of which are features that are important in defining our own species.

In summary, Gran Dolina adult hominids were similar to later Homo sapiens in their large cranial capacity, which is an important indicator of their cognitive abilities and links them to our own species. While they may not have produced art or had particularly wide nasal apertures, their brain size suggests that they had a level of complexity that was similar to our own early ancestors. Thus, the correct option is b.

"Antibodies and enzymes" are two functions of proteins, but compounds that help maintain fluid and pH balance and primary energy source are not functions of proteins.

Antibodies: Proteins produced by the immune system that bind to foreign substances, such as bacteria or viruses, and help to neutralize or eliminate them from the body.

Enzymes: Proteins that act as catalysts in chemical reactions, increasing the rate of reaction by lowering the activation energy required. Enzymes are involved in many biochemical processes in the body, including digestion, metabolism, and DNA replication.

Compounds that help maintain fluid and pH balance: These compounds are not proteins, but rather include electrolytes such as sodium, potassium, and chloride, which help to regulate the balance of fluids and maintain the pH of the body's internal environment.

Primary energy source: The primary energy source for the body is glucose, which is a type of carbohydrate. While proteins can be broken down and used for energy in certain situations, they are not the primary energy source for the body.

Explanation:

The process of evolution that involves a change in the DNA sequence that leads to evolutionary change is called a mutation.

A mutation is a sudden and lasting alteration in the DNA sequence that can influence genetic variation. Changes in the DNA sequence can influence phenotype, which may or may not have an effect on an organism's fitness. Mutations occur spontaneously, either from errors in DNA replication or from exposure to mutagenic agents. Mutations may happen in either coding or non-coding regions of the DNA, and they can be either silent or expressed.

Evolution is a natural process that results in the gradual change of inherited characteristics in populations over generations. It is the process of alteration in the inherited characteristics of species over successive generations. In other words, it is the process of gradual changes that happen to species over time as they adapt to their environments. It can be defined as a change in the gene frequency in a population over time.

As the chemical characteristics of each amino acid are forces that result in intermolecular interactions, the amino acid sequence of a protein influences the shape of the protein.

Proteins are created when peptide bonds join the amino acids. The protein is then folded into precise three-dimensional structures as a result of the forces of other amino acids and the effects of their R-groups.

However, a change at some locations, such as conserved residues, might affect both the protein's structure and function.

Survivorship curves and life tables are both used in demography to study population dynamics, but they serve different purposes and focus on different types of data.

A survivorship curve is a graphical representation of the pattern of survival over time for a cohort (group of individuals born at the same time) in a population. Survivorship curves are typically classified into three types, based on the shape of the curve: Type I, which shows high survival rates for most of the lifespan and then drops sharply towards the end (typical of humans and other large mammals).

The data found in a life table includes the age-specific mortality rates, which are used to calculate the probability of surviving to each age or time point; the age-specific fertility rates, which are used to calculate the number of offspring produced by each female in the population; and the population size and structure, which are used to calculate the net reproductive rate and other demographic parameters.

Answer:

1) b) hypotonic

2) a) hypertonic

3) a) water

4) a) B to A

5) c) osmosis

Explanation:

We have two compartments with water (A) and a solution in which the solvent is water and the solute is starch (B). The solutions are separated by a semipermeable membrane, which means that only the water molecules pass through the membrane.

1) In comparison with B, compartment A has a lesser amount of solute so it is hypotonic.

2) In comparison with A, compartment B has more solute (starch) so it is hypertonic.

3) The solvent is water, which dissolves the solute (starch).

4) Only the water molecules will pass through the membrane, and the molecules always move from the compartment with a higher concentration of solute (B) to the compartment with a lesser concentration of solute (A). So, the water moves from B to A.

5) The process in which the molecules of solvent move from a more concentrated solution to a less concentrated solution through a semi-permeable membrane is called osmosis.
