Answer:

Carbon dioxide dissolve readily in sea water hence makes it high in carbonic acid concentration. The fresh water will dilute the concentration of carbonic acid thus preventing the crab from being exposed to high concentrations which can dissolve its shell.

The ATP that is generated in glycolysis is produced by substrate-level phosphorylation, a very different mechanism than the one
belka [17]

Answer: Phosphorylation reactions involve the addition of a phosphate group to another molecule called ADP (adenosine diphosphate)

Explanation:

Phosphorylation can of two kinds:

I) Substrate-level Phosphorylation which occurs when ATP is produced from the phosphorylation of ADP coupled to the loss of hydrogen atoms from an organic substrate

II) Oxidative Phosphorylation occurs when ATP is produced from the phosphorylation of ADP by using proton pump fuelled by the electron transport system.

Note that the difference between both (I and II) is that the former occurs independent of the electron transport system, UNLIKE the latter.

When NADH passes its electrons into the Electron Transport System, NADH is chemically:
erik [133]

Answer:

Option D, oxidized

Explanation:

The NADH gets oxidised when it passes its electrons into the Electron Transport System

Oxidization is a process in which one element or compound loses its electron to other chemical element or compound thereby itself getting oxidised and reducing the other one (the one who gains the electron).

Here in the electron transport system, the NADH loses or donates its electron to the Electron Transport System thus chemically it gets oxidized.

Hence, option D is correct

Congenital analgesia is a rare autosomal recessive trait. What is the likelihood that the first two offspring of a cross between
telo118 [61]

The likelihood that the first two offspring of the cross will have congenital analgesia would be 1/16

<h2>Autosomal Recessive Traits</h2>

For autosomal recessive traits, two recessive alleles are needed for the trait to manifest while one recessive allele means heterozygosity.

In this case, let us assume that congenital analgesia is represented by the allele b; heterozygous individuals will, thus, be Bb.

            Bb    x    Bb

          BB   Bb   Bb   bb

Probability of producing unaffected offspring = 3/4

Probability of producing affected offspring = 1/4

Likelihood of the first two offspring having congenital analgesia = probability of first having congenital analgesia and the second having congenital analgesia

    = 1/4 x 1/4

        = 1/16
