Answer:
Blood vessels which help the body carry red blood cells throughout the bodies functions.
Explanation:
Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells.
Answer: umbrellaology is not science
Explanation:hope I helped :)
Answer:
No, this is not consistent with the principle of independent assortment.
Explanation:
The principle of independent assortment states that alleles from different genes assort independently. This means that if a plant has a genotype Aa Bb, all four alleles (A, a, B, and b) are going to segregate equally, so we will have the following four gametes after meiosis:
- AB
- Ab
- aB
- ab
If the researcher finds that two of the four products are AB, probably there would be a deviation of Mendel's laws.
Answer:
Gradually, as generations of elephants continued to selectively use and develop their trunks.
Explanation:
Jean-Baptiste Lamarck was famous French Naturalist. He was a soldier, a biologist and an academic. He gave an early theory of evolution known as the theory of Lamarckism.
It was Lamarck who first believed that elephants earlier had small trunks. But eventual when there was scarcity of food and water, the elephants stretched out its trunk to reached out for food such as trees and also water. And as a result their offspring inherited long and powerful trunk.
In his theory of Lamarckism, he believed that the species passes on its traits to the offspring which they acquired through their use in their lifetime. In this case, the elephants might have used their trunks in such a way that they became long and strong over time and they passed tis trait to their babies.
The best answer to the question above would be the first statement. Cardiorespiratory endurance affects physical fitness in such a way that it increases the efficiency with which the body delivers oxygen and nutrients to its cells.
