Answer:
Arteries have thick walls composed of three distinct layers (tunica) Veins have thin walls but typically have wider lumen (lumen size may vary depending on specific artery or vein) Capillaries are very small and will not be easily detected under the same magnification as arteries and veins.
Explanation:
Answer:
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. ... Rather, a genetic mutation causes a difference in fur color, which may help that rabbit hide better in its environment.
Explanation:
Answer:
B. cv+cv w+w
Explanation:
Fruit flies have a special nomenclature to write the genotype of individuals.
- If the mutation is recessive, you have to write it with lowercase letter(s).
- If the mutation is dominant, you have to write it with capital letter(s).
- Wild-type alleles are indicated with a superscript plus (+).
In this problem, both crossveinless (cv) and white (w) mutations are recessive.
<u>For that reason, a heterozygous individual's genotype for both genes will be written as:</u>
<h2>
cv⁺ cv w⁺ w</h2>
