Biology
1 answer:
tatyana61 [14]3 years ago
6 0
Electron Transport Chain or ETC is a series of compounds which transfer electrons to electron transfer from electron donors thru a redox reaction which in turn, couples this electron transfer with the proton transfer (H+ ions) through the membrane.
<span>The negatively charge particles that chlorophyll loses to the transport chain or ETC are replinished by the molecules of water. Water is divided and electrons from it are used to replace the electron found in the chrlorophyll pigment.</span>

What does the immune system produce to help fight future infections with the same type of virus that is introduced in a vaccine?
Stolb23 [73]
The immune system, when coming in contact with a new foreign entity, (Introduced by the vaccine), will first digest the foreign entity with white blood cells to determine its molecular makeup, the white blood cell will then proceed to construct specific antibodies t that will cling to the antigens of the invader, this will help the body know what is foreign and what is friendly! now, after you have fought an infection, your body will set aside certain cells called memory cells, these cells can live for weeks to years within the Lymphatic system as dormant cells, however, if the invader were to show itself again, the antigen presence from the invader would trigger the dormant memory cell to become active and mass produce the antibodies specific for that strain of infection. therefore preventing the show of symptoms due to the early warning system now in place.  

Hope this helps! :D

An animal has a diploid chromosome number of 60. Suppose that the first meiotic division of a germ cell is normal, but a single
ella [17]

Answer:

Two gametes end up with 30 chromosomes, one gamete will have 31 and one will have 29.

Explanation:

During meiosis, a single diploid cell divides into four haploid cells with half the chromosome number than the parent cell.

During meiosis I, homologous chromosomes separate and the chromosome number in the two daughter cells goes down by half. During meiosis II, the "sister" chromatids separate, and the chromosome number in the respective daughter cells remains the same.

Non-disjunction of a single dyad in meiosis II causes that one of the daughter cells will have an extra chromosome, and another will be lacking one. The two other gametes will be normal.

I drew a simple example of what would happen during meiosis of a 2n=4 cell if there was non-disjunction in a single dyad during meiosis II.
