Answer: A. An animal may be a regulator for one environmental variable but a conformer for another.
Explanation: 'An animal may be a regulator for one environmental variable but a conformer for another' is the correct statement when describing feedback control in animals. Animals are constantly adjusting the internal and external behavior or processes in other to attain a steady state or equilibrium through a process called homeostasis. The adjustments are required to maintain a set range in body glucose, calcium, temperature and so on to aid efficient function of the body system.
For instance temperature, cold-blooded animals or ectotherms depends on external heat sources, therefore conform to the environmental temperature While endotherms possess the ability to maintain a constant steady temperature independent of the environment.
The answer is D) to release energy from lipids stored throughout the body.
Answer:
a. osmosis (water must pass through the cell membrane so it is osmosis) b. neither (the saliva is secreted) c. diffusion (the dye doesn't pass through a membrane) d. diffusion"
Explanation:
I'm not sure, but I hope it helps.
This is true.
Facilitated diffusion is a process by which molecules are transported across the plasma membrane with the help of membrane proteins.
It is a type of passive transport in which no energy from the cell is required for the process because a concentration gradient exists that allows movement of particles without expending cellular energy.
Materials diffuse across the cell membrane with the help of membrane proteins some of which are known as carrier proteins.
Membrane proteins are proteins that are attached to, or associated with the membrane of a cell or an organelle.
