klasskru [66]

Explanation:

During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.

Juli2301 [7.4K]

Answer:

In babies born with congenital defects during the German measles rubella epidemic the specific cause of these birth defects was most likely the development of rubella virus infections in embryos.

Explanation:

Options for this question are:

<em>1. </em><em>The development of rubella virus infections in  embryos. </em>

<em>2. The failure of zygotes infected with rubella to develop </em>

<em>3. Mutations in the nerve cells of pregnant  females at the time of the rubella epidemic .</em>

<em>4. An increase in the amount of time needed for  healthy embryonic development.</em>

Rubella is a viral infection caused by a virus of the genus Rubivirus, considered highly teratogenic during the phases of pregnancy where the embryo and the fetus are developing, that is, before 20 weeks of gestation.

<u>The virus is transferred to the embryo or fetus by the mother's blood, acquiring the disease</u>, which can cause abortions or visible malformations at birth, which is called <u>Congenital Rubella Syndrome</u> (CRB).

CRB is responsible for producing cardiovascular, renal, neurological malformations, loss of vision or hearing, problems that German children born during the epidemic probably had.

WARRIOR [948]

Answer:

C. NAD⁺  

Step-by-step explanation:

NADH is oxidized to NAD⁺ in Complex I of the Electron Transport Chain.

NADH ⟶ NAD⁺ + H⁺ + 2e⁻

The electrons continue through the Electron Transport Chain, and the NAD⁺ is used in three places during the Krebs Cycle.

(a) Isocitrate to oxalosuccinate

Isocitrate + NAD⁺ ⟶ oxalosuccinate + NADH + H⁺

(b) α-Ketoglutarate to succinyl-CoA

α-ketoglutarate + NAD+ + CoA → succinyl CoA + CO₂ + NADH

(c) Malate to oxaloacetate

Malate + NAD⁺  ⟶ oxaloacetate + NADH + H⁺

The NADH produced by these three reactions can then be used by Complex I in the Electron Transport Chain.
