Biology
2 answers:
andre [41]3 years ago

Answer: Minerals dissolve and crystallize.

The remains of plants and animals.

Explanation:

The chemical sedimentary rocks form when the parent material weathers into a sediment. The sediment includes chemical inorganic minerals and partially or completely degraded organic matter that comes from the remains of plants and animals. The layers of sediments get compacted with overlying heat and pressure which leads to the formation of chemical sedimentary rocks.

Including the conversion of pyruvate to acetyl coA, how many NADH, FADH2, ATP, and GTP molecules are produced during the kreb’s
Mnenie [13.5K]

Similar to the conversion of pyruvate to acetyl-CoA, each pyruvate molecule loses a carbon atom with the release of carbon dioxide. During the decomposition of pyruvate, electrons move to NAD + to produce NADH. It is used by cells to produce ATP.

  • NADH: Three molecules are produced in the Kleb circuit

  • FADH2: One molecule is produced in the Kleb circuit

  • ATP or GTP: From each molecule of pyruvate during the conversion of succinyl-CoA to succinic acid Two molecules of ATP are produced. The presence of the enzyme succinyl-CoA synthetase.

In Drosophila, vestigial (partially formed) wings (vg) are recessive to normal long wings (vg+) and the gene for this trait is a
Marina CMI [18]

Answer/ Explanation:

a. The genotype of a homozygous white eyed long winged female would be Vg+Vg+XrXr. We denote the white allele as recessive (r) because the XY male only has one copy and yet has red eyes, so the red eye trait (R) must be dominant. A homozygous red eyed vestigial winged male would have be VgVgXRY. The possible gametes for the female are Vg+Xr only. For the male, the possible gametes are VgXR or VgY

The attached punnett square shows the results of the cross. The females will all be Vg+VgXRXr. The males will all be Vg+VgXRY (must inherit Y from father). That means they will all  have normal length wings, the males will have white eyes and the females will have red eyes.

b. The F2 flies arise from intercrossing the F1, so the cross will be Vg+VgXRXr x Vg+VgXRY. The possible gametes for the mother are: Vg+XR, Vg+Xr, VgXR or VgXr. The possible gametes for the father are Vg+Xr

, Vg+Y

, VgXr

, VgY

. The attached punnet square shows this cross. The ratio of the phenotypes will be 6:6:2:2, or 3:3:1:1 (long-winged red eye: long-winged white eye: vestigial wing red eye: vestigial wing white eye), genotypes shown in the attachment.

c. F1 cross back to the mother would be Vg+VgXRY x Vg+Vg+XrXr. The genotypes are shown in the attached punnet square. The offspring will all be long-winged with white eyes. The F1 to the father would be Vg+VgXRXr x VgVgXRY. The ratio would be 3:3:1:1 long-winged red eye: long-winged white eye: vestigial wing red eye: vestigial wing white eye
