Why is the ability of the cell membrane to be "picky" important?
Yuliya22 [10]

Answer:

Hi there!

Your answer is:

It is very important for the cell membrane to be <em>semi-permeable</em> because the ability to pick and choose what comes in and out of the cell keeps the cell safe! The membrane can choose to block out nasty germs and can also choose to get rid of internal waste.

An example of when this is important is in this scenario:

Let's say the cells are in a really salty solution. Naturally, salt will want to pull the water out of the cell. If the membrane <u>wasn't</u><u> </u> semi permeable, the water would listen to the salt and leave the cell. This would cause cell death. <u>BECAU</u><u>SE</u> the membrane is semi permeable, they can choose <em>not</em> to give the salt any water, keeping them alive

Hope this helps

Identify the 2 major groups of enzymes that make the redox reactions possible: Describe their role in these reactions.
adell [148]

Answer:Enzymes that makes redox reactions possible in a biochemical process includes those that help to catalyze the transfer of electrons, atoms, or functional groups.

Explanation:

Here are some class categories of these enzymes and their roles ;

• Oxidoreductases - Transfer of electrons (hydride ions or H atoms)

• Transferases - Group- transfer reactions

• Hydrolases - Hydrolysis reactions (transfer of functional groups to water)

• Lyases - Addition of groups to double bonds, or formation of double bonds by removal of groups Transfer of groups within molecules to yield isomeric forms

• Isomerases - Formation of C-C, C-S, C--0, and C-N bonds by condensation reactions coupled to ATP cleavage

The above are however classified, given code numbers, and assigned names according to the type of transfer reaction, the group donor, and the group acceptor.

When colorblind women married a male with normal vision, all their daughters have normal vision and all their sons are colorblin
worty [1.4K]

Answer:

X-linked recessive

Explanation:

The trait is a sex-linked trait because the daughters are not colorblind, but the sons are. We know this its recessive because the daughters have inherited the mother's X chromosome that has the colourblindness trait, but are not colorblind because the father's X does not have the colourblindness trait. The sons are colourblind because they inherited the X from their mother with the colourblindnese trait and a Y from their father. The colourblindness trait or normal vision trait is not carried on the Y, so the mother's X chromosome's trait is expressed.

Sorry if it's confusing i tried my best to explain it

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
