Which is a characteristic of exponential population growth?
Rudik [331]

A characteristic of exponential population growth is that <u>resources are consumed exponentially during all phases </u>

Explanation:

Exponential growth is a type of growth where the population doubles its population size with each generation. Bacteria are the best examples of organisms that can exhibit this type of growth. However, just as the growth of the population is exponential, so is the consumption of resources. With each generation as the population doubles, the strain on the resources increases. This continues until the resources become depleted and cannot sustain the population numbers. Because resources are always infinite, this is why it is rare to find any population, including bacteria, sustaining exponential growth for long periods. Most common population growth is logistic (S-shaped).

What is parthenogenesis? give an example
ANEK [815]

Answer:

It's a form of asexual reproduction!

Development of the offspring happens without fertilization in this type of reproduction.

The two main ways in which parthenogenesis happens is by apomixis or automixis. Through apomixis , the egg cells are produced by mitosis. Through In automixis, egg cells are produced by meiosis.

Mitosis = a part of cell cycle: replicated chromosomes are separated into 2 nuclei

Meiosis = type of cell division that reduces the chromosome number by half. So now there is four haploid cells that are  genetically distinct from their parent cell.

Example:

An example of an animal that can use this reproduction is a bonnethead shark! Once a shark had a baby in a tank that only had three females!

Blood stasis, changes in the vessel wall, and certain medications affect the: Select one: a. systolic blood pressure exclusively
Luda [366]

Blood stasis, changes in the vessel wall, and certain medications affect the ability of the blood to effectively clot.

Explanation:

Clotting is also known as blood coagulation. It is the process by which blood forms a clump which is either gelatinous or semisolid in state.

Clotting is very necessary because it prevents unnecessary loss of blood in case of cuts and injuries.

However the tendency of blood to form random clots is also very harmful because it might lead to blockage in the blood vessels.

Effective blood clotting can result from:

  • Blood stasis, a condition in which the flow of blood in the vessels is hindered,
  • Changes in vessel walls.
  • Certain medication that prevents blood clotting or decreases blood density.
