An electron transport chain (ETC) is a series of complexes that transfer electrons from electrondonors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane.

The circulatory and skeletal systems work together in the following way: skeletal system produces cells in the bone marrow while the circulatory system transports cells where they need to go (option A).

<h3>What is skeletal and circulatory system?</h3>

Skeletal system is the system that works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.

Circulatory system, on the other hand, are parts of an animal body comprising the heart, veins, capillaries and arteries. It circulates blood and lymph through the body.

According to the above description of both systems, the skeletal system produces blood cells in the bone marrow while the circulatory system transports these cells.

melamori03 [73]

Acid-fast bacteria or acid-fast bacilli can be defined as the group of bacteria that have the ability to resist their decolonization by the acids which are used during the staining process.

An infection that is caused due to an acid-fast organism indicates that the individual is suffering from Tuberculosis or other myobacterial diseases.

An acid-fast bacteria has many protective and invasive techniques which makes the infection difficult to treat, and thus, long-term course of antibiotics is needed for the treatment of such infections.

The cell membrane of a red blood cell will allow water, oxygen, carbon dioxide, and glucose to pass through. Since other substan
Mrrafil [7]

Answer:

The correct answer would be B. semi-permeable.

Plasma membrane of any cell including red blood cell is semi-permeable in nature as it is made up of lipid bilayer.

It permits the passage of certain substances across the membrane while it blocks other substances.

Gases, small uncharged or non-polar substances such as oxygen, carbon dioxide, et cetera can easily pass through the cell membrane of a cell.

Large or charged molecules such as proteins, sodium ions, potassium ions et cetera can not pass through the cell membrane. They require carrier proteins to pass through the membrane.

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
