Answer B burning fossil fuels in vehicles, power stations, and factories
Explanation:
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.
Depolarization is to excitation, while Hyperpolarization is to inhibition.
Option 4 is correct.
Hyperpolarization is opposite of Depolarization.
Depolarization is a process by which cells undergo a change in membrane potential. It is a process of shift in electric charge that results in less negative charge inside the cell.
Hyperpolarization is when the membrane potential becomes more negative at a particular spot on the neuron’s membrane.
This answer would be considered True.
Answer:
The scheme of the tautomers of cytosine, guanine and thymine are found in the attached file
Explanation:
The primary imine-amine tautomerism occurs in heterocyclic compounds where hydrogen may be forming the amino group (primary amine form) or migrate to adjacent nitrogen (imine form), may occur in some nitrogenous bases such as cytosine. Thymine shows double lactam-lactymal tautomy (where hydrogen migrates from the nitrogen atom to the oxygen atom of the heterocycle oxo group (lactam form) and vice versa (lactose form)), and guanine and cytosine can both.
