Essential amino acids are the ones that your body can’t make on its own. These are ones that come from food and need to be obtained in order to survive. Your body needs these acids because they are like building blocks of proteins and they’re needed for vital processes like building proteins and synthesis of hormones and neurotransmitters.

Hope this helps

Amino acids make up proteins, and proteins are needed for proper growth in humans. They’re essential because, without them we wouldn’t have the nutrients we need to survive. I hope this helped!

A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. When the rock is cut in half, what is the volume and d
spayn [35]

Answer:

Volume= 4 cm³

Density= 2 g/cm³

Explanation:

We have the following data:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³

How do the tides affect organisms that live in tidal waters?
4vir4ik [10]
<span>Tides and currents carry nutrients, moderate temperatures, and influence conditions in numerous ecosystems. The relationship between society and tides and currents is obvious as coastal cities built to withstand prescribed levels of tidal surge are now being impacted by record breaking tidal surges, and the building of solid coastal structures do not allow waves to dissipate energy on land but deflect their energy to other coastal areas along the shore.

hope this helps</span>

Genetic drift simulation:
Airida [17]
Unlike natural selection, genetic drift does not depend on an allele's beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation.
