The appropriate answer is the peristaltic muscle muscle contractions.
Peristalsis, involves involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but may take place in other hollow tubes of the body, that occur in progressive wavelike contractions. Peristaltic waves occur in the esophagus, stomach, and intestines.

<span>The correct answer is peristaltic muscle contractions.
</span>  Peristaltic muscle contractions include contraction and relaxation of smooth muscles that produce a peristaltic wave, which propels the bolus (mix of food and saliva which travels down the digestive tract). Muscles contract behind the bolus to prevent it from being squeezed back into the mouth and the rhythmic contractions work to rapidly force it into the stomach.

Match the functional groups with their structures:
evablogger [386]
The true answer of your question is :

OH : HYDROXYL GROUP

NH2 : AMINO GROUP

CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )

COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.

I hope you’ll understand everything, anyway if not i’m always here to help. ♥️

In 1998, scientists discovered that the expansion of the universe has been accelerating.
KengaRu [80]

Answer:

Option A (dark energy) is the right answer.

Explanation:

  • A hypothetical supplier of power that creates a force that contradicts gravity, which is assumed to have been the catalyst of accelerated universe development.
  • Hypothetically, dark energy counteracts the kinetic energy including its beginning of the globe, meaning that perhaps the multiverse does not have intrinsic curvature, although observational measurements presently indicate.

Some other three choices have no relation to the particular situation. Thus option A would be the right solution.

ivolga24 [154]

Answer:

Children born to mothers with dark skin, living far from the equator.

Explanation:

I would say this is the answer but I'm not sure. This is just what I think. I asked my mom about it and she said the same thing I did. I hope this helps.
