Arctic/Polar is the best answer
Anerobic organisisms need to make oxoygen just like photosynetheic plants
Answer:
C) Effector – Analyzes receptor output to determine if a controlled condition is correctly maintained.
Explanation:
- Effector does not analyze receptor output to determine if a controlled condition is correctly maintained. Effector just receive commands from control center and follow them.
- Control center analyze receptor output to determine if a controlled condition is correctly maintained.
Example; The temperature receptors detect the change in temperature (high temperature), they send the information to control center ( hypothalamus) to analyze the information and the control center send the command to blood vessels to dilate and active the sweat glands.
Early cleavage divisions in most embryos are also rapid. One reason for this is that cleaving cells have a modified cell cycle, in which the two gap phases, G1 and G2 are completely omitted, and the cells cycle rapidly between M and S phases. In addition, because the major cytoskeletal systems of the cells are largely devoted to mitosis (microtubules) and cytokinesis (microfilaments) during rapid cleavage division, there is typically an antagonism between periods of rapid cell division and cell movement. Thus as the embryo approaches gastrulation, there is a tremendous slowing in the rate of division (note the slope of the curve at the right).
Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.
