The given question is incomplete. The complete question is:

In humans, the maintenance of a stable internal temperature is a direct result of___________.

a. detection of and reaction to stimuli in the environment

b. digestion of starches and absorption of protein from the internal environment

c. diffusion of water and excretion of glucose to the external environment

d. transport of ATP and locomotion through the environment

Answer:

a. detection of and reaction to stimuli in the environment

Explanation:

Thermoreceptors present in skin layers of the human body sense the deviation of the body temperature from the normal range. As the body temperature rises above normal, the thermoreceptors send signals to the brain which n turn signals dermal blood vessels to dilate and sweat glands to secrete sweat. The heat from the body surface is lost to the surroundings to drop the body temperature towards the normal range.

On the other hand, when the body temperature goes below the normal range, thermoreceptors send signals to the brain which in turn signals dermal blood vessels to constrict to conserve the body heat. If body temperature continues to drop, muscles are signaled to contract involuntarily to generate body heat to raise the body temperature towards the normal range.

An allosteric protein would be expected to

Mumz [18]

Answer:

All of the above.

Explanation:

Allosteric protein may be defined as the protein that has multiple ligand sites and binds to the site other than the active site. Allosteric protein is involved in the regulation of metabolic pathways of the body.

Allosteric protein does not follow the Michaelis-Menton kinetics. These proteins are multisubunit protein and has the different binding sites for the effector as well as substrate molecule. These proteins are present at the committing steps of the metabolic pathways.

Thus, the correct answer is option (e).

In what type of situations would random sampling (last lab) be useful?

egoroff_w [7]

In some types of research the target population might be as broad as all humans, but in other types of research the target population might be a smaller group such as teenagers, pre-school children or people who misuse drugs.

It is more or less impossible to study every single person in a target population so psychologists select a sample or sub-group of the population that is likely to be representative of the target population we are interested in.

This is important because we want to generalize from the sample to target population. The more representative the sample, the more confident the researcher can be that the results can be generalized to the target population.

One of the problems that can occur when selecting a sample from a target population is sampling bias. Sampling bias refers to situations where the sample does not reflect the characteristics of the target population.

Archeological evidence suggests that Neanderthals might have been aware of the medicinal properties of plants over 60,000 years

VARVARA [1.3K]

Answer:

It could be prevent Ga from binding to the epinephrine receptor.

Explanation:

Hindering GTPase action will make G-protein to tie to adenyl cyclase for all time so Glucose is delivered persistently.

Diminishing the proclivity for GDP will build the opportunity of authoritative of GTP to G protein which thus will initiate the pathway.

On the off chance that G protein ties with adenyl cyclase it will invigorate it.

Yet, in the event that the G-protein is kept from official with epinephrine receptor, at that point the receptor can't enact trade the guanine nucleotide to G-protein for initiation. Thus the G-protein stays in latent state.
