in mammals, an increase in the temperature of the preoptic area of the hypothalamus activates physiological mechanisms for heat
serious [3.7K]

True. In mammals, an increase in the temperature of the preoptic area of the hypothalamus activates physiological mechanisms for heat dissipation including vasodilation.

<h3>What is vasodilation?</h3>

Vasodilation, as it is known in medicine, occurs when blood vessels in your body open up, enabling more blood to flow through them and resulting in a reduction in blood pressure. Without your knowledge, your body goes through a routine procedure like this. It can also be brought on by the foods and beverages you consume as well as the drugs you take. Vasodilation may also be a sign of a particular illness.

The two of the many functions that your blood serves in the body:

  • Carrying oxygen and nutrients
  • Aiding in temperature regulation in your body.

Your body's blood arteries are more complex than simple tubes that remain constant in size. Your blood arteries include muscle as well, and that muscle regulates how wide or narrow they are at any particular time. Vasodilation occurs when blood vessels enlarge. Vasoconstriction is the opposite process, which occurs when blood vessels narrow and contract.

Nady [450]

Answer:

D. archaeal membranes contain L-glycerol.

Explanation:

Archaea and eubacteria differ from each other with respect to the nature of membrane lipids. Lipids present in the membranes of the archaeans have the hydrocarbons derived from isoprene units. These hydrocarbons are branched and are attached to the glycerol with help of ether linkage. Ester linkages are present in eubacteria. The glycerol present in the archaeans is L- glycerol. Bacterial membranes have D-glycerol present in their lipids.

Nadph builds up in the ________________ during electron transport.
Yanka [14]

NADPH builds up in the STROMA of the chloroplasts during electron transport. In chloroplasts,  NADP+ is reduced by the ferredoxin-NADP+ reductase.

Nicotinamide adenine dinucleotide phosphate (NADPH) is the reduced electron form of NADP+.

The NADPH coenzyme is generated during the last step of the electron transport chain of the light-dependent reactions of photosynthesis.

NADPH is used by plant cells as an electron donor in different reactions associated with dehydrogenase and reductase enzymes.
