Which statement describes an unanticipated negative impact of a

Biology
1 answer:
ser-zykov [4K]3 years ago
4 0

Answer:

C.

Explanation:

"The use of smartphones and tablet computers at bedtime can

disrupt sleep, affecting people's health."

Even though smartphones and tablet computers are great technological advances from what technology used to be, they disrupt our sleep, affecting our health. The people who made the advance, probably weren't thinking that they would affect us in a health involved way. They're making even better advancements to our technology today, even right now, hopefully fixing the negative impact it has on us, but also searching for anymore that might become an issue for our health.

The presence of two peripheral efferent neurons in a pathway is typical of the ________ division.
Svetllana [295]
The presence of two peripheral efferent neurons in a pathway is typical of the autonomic division. The autonomic division is part of the vertebrate nervous system and this system is responsible for involuntary action regulation (regulation of the intestines, heart, and <span>glands).

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

During meiosis I, _____________________. Group of answer choices homologous chromosome pairs are separated the chromosome number
spayn [35]

Homologous chromosome pairs are separated

Meiosis 1 refers to the initial stage of meiosis where one parent cell divides into two daughter cells. This stage is where homologous pairs of chromosomes will segregate and separate from each other and move into the two daughter cells which result in the division of the total chromosomal number by half.

<h3>What happens during Meiosis 1 ?</h3>

Meiosis I ends when the chromosomes of each homologous pair arrive at opposing poles of the cell.

  • The microtubules disintegrate, and a new nuclear membrane forms around each haploid set of chromosomes.

  • The chromosomes uncoil, forming chromatin again, and cytokinesis occurs, forming two non-identical daughter cells.
