cytokinin's regulates cell division in plants.

  • A group of plant hormones known as cytokinins (CK) encourages cytokinesis, or cell division, in the roots and shoots of plants.
  • A group of plant hormones known as cytokinins (CK) encourages cytokinesis, or cell division, in the roots and shoots of plants.
  • They influence apical dominance, axillary bud formation, and leaf senescence in addition to being largely involved in cell proliferation and differentiation.
  • When leaf cell development is in the proliferation stage or the expansion stage, cytokinins, in the appropriate order, promote cell division and boost cell expansion.
  • Cytokinins decrease the buildup of sugar during leaf senescence, boost the production of chlorophyll, and extend the photosynthetic period. <u>Examples include benzyl adenine, kinetin, and zeatin.</u>

Choose all that apply. Which of the following is true in a comparison of your skin cells to your kidney cells?
ruslelena [56]

Given our understanding of the mechanisms behind genetic expression, we can confirm that when comparing skin cells to kidney cells, the only correct option is option 4 which states that the cells "<u><em>transcribe many different genes</em></u>".

The human genome encodes for <em><u>every gene in the human body</u></em>. This genome sequence is stored in the chromosomes of cells. These chromosomes are identical for every single cell in the human body. Therefore, every cell contains the same DNA, genes, and transcription factors in its chromosomes.

What allows each cell type in the human body the ability to differentiate from one another and complete vastly different functions is the way in which these genes are expressed. Though every cell contains the entire genetic code, only some genes for each cell are transcribed, which results in a different combination of proteins in each cell and leads to the difference between skin and kidney cells (as just one of many examples).

The inheritance of eye color in Drosophila is controlled by genes on each of the fly's four chromosome pairs. One eye-color gene
algol [13]

Answer:

F1 Females  - all wild type

F1 Males  - all wild type

F2 Females  -  - all wild type

F2 Males - 1/2 wild type, 1/2 vermilion

Explanation:

The wild-type allele (Xᵛ⁺) is dominant over vermilion (Xᵛ), which is a sex-linked trait.

Female flies have two X chromosomes, male flies have one X and one Y chromosome.

A homozygous wild-type female fly (Xᵛ⁺Xᵛ⁺) is mated with a vermilion male fly (XᵛY).

The female parent can only produce Xᵛ⁺ gametes.

The male parent can produce either Xᵛ or Y gametes.

When gametes from both parents fuse, the F1 offspring will have the genotypes Xᵛ⁺Xᵛ (females with wild type eyes) and Xᵛ⁺Y (males with wild type eyes).

The F1 females can produce Xᵛ⁺ and Xᵛ gametes. The F1 males can produce Xᵛ⁺ and Y gametes.

When the F1 individuals interbreed, the gametes combine to give rise to the F2 offspring. The possible combination of gametes that will give the different genotypes and phenotypes in the F2 are:

  • Xᵛ⁺Xᵛ⁺ females with wild type eyes
  • Xᵛ⁺ Y males with wild type eyes
  • Xᵛ Xᵛ⁺ females with wild type eyes
  • Xᵛ Y males with vermilion eyes
