Answer:
Mitochondria in brown fat have the ability to produce heat without the need to produce ATP molecules
.
Explanation:
Hibernating bats develop brown fat on their backs between the shoulder blades, but mammals can also store brown fat in their bellies and other parts of their bodies
.
This characteristic that bats and other animals that hibernate possess gives you the possibility of producing energy without the production of ATP through cellular mitochondria.
That is to say, the brown adipose tissue - the main heat-generating organ in the body and is activated with the cold - is also an endocrine organ that secretes signaling factors that activate the metabolism of fats and carbohydrates. The brown adipose tissue helps "burn more calories" and produce body heat from fat.
Options are not provided in the question, so the complete question is as follows:
In the three domain system, the domain Eukarya consists of all organisms that have which of the following?
A. Contractile vacuole
B. Nucleus
C. Chloroplast
Answer:
B. Nucleus
Explanation:
The three domain system include archaea, bacteria, and eukarya.
Eukarya, consists of all organisms whose cells have a nucleus. Eukarya contains multicellular and visible organisms, such as animals, people, plants and trees.
