Which of the following statements about peptide bonds are true? 1) A tetrapeptide contains five amino acid residues. 2) Peptide
Y_Kistochka [10]

The correct answers are:

2) Peptide bonds form from nucleophilic attack by an electron pair on an alpha - amino nitrogen atom on an alpha - carboxyl carbon atom of another amino acid and

4) Peptides are polymers of amino acids.

A peptide bond is an amide type of covalent chemical bond. It is formed between two amino acids:  C1 (carbon end) of one alpha-amino acid and N2 (nitrogen end) of another. Peptide bonds are the basis for the formation of a peptide chain and consequently protein.  Formation of peptide bond is a condensation process, meaning that when two amino acids combine and link, water molecule is released and dipeptide is a product of that reaction.

the ability of the kidneys to remove molecules from the blood plasma by excreting them in the urine is known as .
DIA [1.3K]

the ability of the kidneys to remove molecules from the blood plasma by excreting them in the urine is known as Glomerular filtration. one can estimate the efficiency of Glomerular by GFR Glomerular filtration rate

Measuring measured GFR (mGFR) is a difficult and time-consuming method that is not practicable for patients or doctors, making it difficult to obtain an accurate GFR level. Because of this, medical experts utilise a formula to determine GFR (eGFR). For diagnosing renal disease, which frequently has no symptoms until right before the kidneys fail, accurate estimates of GFR are crucial. A straightforward blood test that evaluates your creatinine levels is the typical method for estimating GFR. The regular breakdown of muscle tissue and the digestion of food protein both produce creatinine, a waste product. In addition to CKD, other factors such as food, muscle mass, or the weight of your muscles, malnutrition, and other chronic conditions can also have an impact on creatinine levels.

biologists is studying two species of lizards in a mountainous region. The two species are separated by habitat with one species
ivann1987 [24]

Answer:

Valley lizard = Oviparous

Mountain lizard = Viviparous

Explanation:

In Darwin's theory survival of the fittest, he believed species adapt or change within their environment. So I believe lizards living in a valley would be more safe to lay their eggs but lizards living in the mountains would be viviparous because of the non-predicted and unsafe environment which could harm the better chances of development of the offspring.
