The right answers are:
A-present in eukaryotic genomes ==> Both exons and introns
B-generally absent from bacterial genomes ==> Introns
C-part of the final mRNA strand ==> Exons
D-code for an amino acid sequence ==> Exons
E-removed from initial mRNA strand prior to translation ==> Introns
F-present in the DNA used as the template for transcription ==> Both exons and introns
In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.
A) Smooth muscle
B) Involuntary
C) Cannot
D) Brain
E) Move
F) Digestive
G) Voluntary
- <u>Adaptations </u><u>are unique characteristics that allow animals to survive in their environment.</u>
- <u> There are </u><u>three </u><u>types of adaptations: </u><u>structural</u><u>, </u><u>physiological</u><u>, and </u><u>behavioral</u><u>. Structural adaptations are how the animal's body functions or looks on the ou</u>tside.
What are 3 ways animals can adapt to their environment?
Animals adapt to their environment in a variety of ways; an animal's color, behavior, defense or diet, for example, may serve adaptive functions.
- Color and Pattern Adaptations.
- Behavioral Adaptations.
- Defensive Adaptations.
- Dietary Adaptations.
What is an example of an animal adapting to its environment?
- Adaptation can protect animals from predators or from harsh weather.
- Many birds can hide in the tall grass and weeds and insects can change their colour to blend into the surroundings.
- This makes it difficult for predators to seek them out for food.

According to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.
<h3>What is population genetics?</h3>
It studies the origin, amount and distribution of genetic variability present in populations.
It explains the variation between individuals, as well as the dynamics of alleles and genotypes within and between populations.
Therefore, we can conclude that according to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.
