Answer:it is a similar thing to natural selection, the ones less effected by it survive and adapt over time to survive the vaccine. However, google defines it this way, "The adaptive immune system, also known as the acquired immune system or, more rarely, as the specific immune system, is a subsystem of the overall immune system that is composed of highly specialized, systemic cells and processes that eliminate pathogens or prevent their growth"

In the electron transport system
antoniya [11.8K]

Answer:

A. NADH and FADH2 both donate electrons at the same location.

Explanation:

In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.

These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.

Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.

NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.

The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.

If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.

Shanghai and Buenos Aires are located thousands of miles apart and in different hemispheres, yet their climates are similar. Wha
liubo4ka [24]
That's because they are in the same climate zone. The earth's climate zones change going from the north pole to the equator, and then from the equator to Antarctica, like a mirror image. The two are found in the same zones on the opposite hemispheres.

Classification problems aid in predicting __________ outputs.
soldier1979 [14.2K]

Answer:

The correct answer is "categorical or discrete".

Explanation:

Categorical or discrete outputs are relatively easy to predict and classifying problems aid to do it so. Categorical outputs are not numeric outputs that do not follow any particular order, while discrete outputs are  responses that can be counted because they are expressed in integer numbers. More complex responses expressed in continuous outputs need further calculations.

Anastasy [175]
It shouldn’t become cancerous if the cell cycle is not damaged. When changes in the chromosomes are detected by the cell, it will enter the G0 stage of interphase and will no longer divide.
