Breathing heavily after you have finished running a race is your body way of
ehidna [41]

Answer:

Breathing heavily after you have finished running a race is your body way of repaying an oxygen debt.

Explanation:

Any kind of exercise that is performed makes our muscles work harder. As a result, more calories get burned by these muscles. To burn the extra calories, more supply of oxygen is required by the muscles. As you exercise harder, the breathing increases and become heavier to bring more oxygen to the lungs. From the lungs, the oxygen is carried to the muscles which are burning more calories.

You breathe heavily at the end of a race to get enough supply of oxygen.

Answer:

Let's complete the question by writing the sequence, from earliest to most recent options

a. 2 → 1 → 3 → 4

b. 2 → 4 → 3 → 1

c. 2 → 3 → 1 → 4

d. 2 → 1 → 4 → 3

e. 2 → 4 → 1 → 3

It's surely going to be e.

e. 2 → 4 → 1 → 3

2. Cambrian explosion occurs.

4. Vertebrates become top predators in the seas.

Explanation:

Gl x Gl

GG, Gl, Gl, ll

gl x gl

gg, Lg, Lg, LL

On the first crossing we'll have 50% Gl and both other genotypes will be 25%

On the second crossing we'll have 50% Lg and both other genotypes will be 25%.

You shoot a deer. you do not see it go down. how long should you wait before trailing the deer? half an hour two hours half a da
svp [43]
You should wait at least half an hour before trailing the deer. You should try to watch carefully and see which way it goes. Chasing a wounded animal yields meat that tastes gamey, so try not to chase. When you do trail, follow the blood trail. Listen carefully while you wait and try to hear where the deer is or if it goes down.

where they execute important functions. The polypeptide chain of these proteins must cross the lipid bilayer. This presents a pr
spin [16.1K]

Answer:

In this case, it is likely that the polypeptide chain assumed an alpha helix configuration because the lipid bilayer did not have beta-barrel proteins.

Explanation:

A polypeptide chain is naturally polar, however, a lipid bilayer is naturally non-polar. This makes it difficult and even prevents the polypeptide chain from crossing a lipid bilayer, since the composition of these two elements does not allow them to mix. In that case, the polypeptide chain has two options to take to successfully cross the lipid bilayer.

The first option that the polypeptide chain has is to allow the creation of twisted beta sheets in the shape of a closed barrel in its structure. This only works if the lipid bilayer has beta barrel proteins in its composition to act as a transport channel for the polypeptide chain. However, few lipid layers have this protein.

Most likely, the polypeptide chain assumes an alpha helix conformation to cross lipid bilayers that do not have beta-barrel proteins. By assuming the beta conformation, the polypeptide chain reinforces the hydrogen bonds present in its composition, allowing it to cross the lipid bilayer without having its conformation and structure disassembled.
