Answer:

TRUE

Explanation:

These kind of mutations in the bacterial genome will lead to the phenomenon of bacterial resistance. As described, the peptidoglycans continues to be cross linked as usual but the over all new resulting cell wall has developed a resistance against the antibiotic penicillin due to non recognition enhancement by the bacterial resistance genes.

What blood vessel is a tributary of the hepatic portal vein?
inysia [295]

According to the research, the linear vein is a tributary blood vessel of the hepatic portal vein.

<h3>What is the hepatic portal vein?</h3>

The linear vein is one of the branches of the celiac trunk that supplies the spleen and gives off branches to the stomach and pancreas.

Therefore, we can conclude that according to the research, the linear vein is a tributary blood vessel of the hepatic portal vein.

How do the sequence and composition of amino acids in a protein influence how a protein folds up
Fynjy0 [20]

Answer:

See the explanation below, please.

Explanation:

The amino acid sequence of a protein will determine the interactions inside and with the environment (that is, it will influence the conformations that are adopted at physiological temperature: the degrees of freedom). Example: the proline amino acid (Pro) has a cyclic structure, which implies a limitation in the random movement of the polypeptide chain.

In proteins, the primary structure determines the sequence of the amino acid sequence of the polypeptide chain (amount of amino acids present and their order by means of peptide bonds).

A machine require 2,000 joules to raise a 20 kilogram block a distance of 6 meters. How efficient is the machine?
Nataly_w [17]
Potential energy = (mass) x (gravity) x (height) .

To raise the 20kg block 6 meters, you need to give it

                         (20 kg) x (9.8 m/s²) x (6 m) = 1,176 joules

of potential energy.

Your machine takes 2,000 joules of energy to give the block
the 1,176 joules that it takes.

Your machine is only  (1176 / 2000) = 58.8% efficient .

The other 'missing' 824 joules of energy doesn't just disappear.
It heats the machine, and the air around it.  The final result is
that when you use that machine to lift blocks, you have to use
even MORE energy, to blow cool air on the machine and prevent
it from overheating and breaking.
