AnnZ [28]

Answer: Primary

Explanation: The primary level of protein structure explains the sequence of amino acid linked together by peptide bonds to form polypeptide chains . A slight change in the amino acid sequence of Hemoglobin can alter hemoglobin function.

The primary level of protein structure is essential in the function of the protein any alteration in the amino acid sequence can disrupt the function of the protein.

Which of the following is a true statement?
FrozenT [24]

Answer:

a. Anabolic pathways build molecules, require energy, and are endergonic.

Explanation:

<em>Anabolic pathway </em>describes the metabolic reactions that<em> </em><em>build up</em><em> complex molecules from simpler ones</em>, typically via condensation (monomers covalently joined producing water as a by-product).<em> It </em><em>requires energy </em><em>to construct new bonds, this means is </em><em>endergonic</em><em>.</em>

The catabolic pathway, on the other hand, describes metabolic reactions that<em> </em><em>break complex molecules down </em><em>into simple ones</em>, typically via hydrolysis (consumption of water to break bonds within the polymer). <em>It </em><em>releases energy </em><em>when these bonds are broken, this means it is </em><em>exergonic</em><em>.</em>

Considering this information we can conclude that the correct answer is a. Anabolic pathways build molecules, require energy, and are endergonic.

I hope you find this information useful and interesting! Good luck!

Select the statements that explain why duplication is a driving force for evolution and the generation of new genes.
Paha777 [63]
<span>It is vitally important to life, any form of life. Life in it's self is what we are all striving to grasp, hold and not let escape. It is the endless search for meaning to understand and comprehend. Evolution which is the symphonic struggle of nature to overcome and create the most suitable specimen ensuring its survival within its species from its predators and the world at large. Duplication is natures way to regenerate and strengthen the gene pool of species. It allows newer generations to improve on the genes to enable it to adapt better to the current environment is is facing. It is a constant and never ending process.</span>
