In escherichia coli, the c ring of atp synthase is composed of 12 c subunits. For one fully productive revolution of this ring, how many protons are transported across the membrane for each molecule of atp produced?.

Answers

Answer 1

Answer: The membrane-spanning component of human mitochondrial ATP synthase (best known as FO, reflecting the fact that it can be inhibited by oligomycin) is composed by no less than nine polypeptides (a, b, c, d, e, f, g, F6 and 8), while the soluble catalytic core of the complex (F1) consists of five different subunits

Add another bar to the chart that would represent Han
chinese at low altitudes. Pay attention to the height of
the bar and provide a short explanation for your choice.

Answers

Assuming height of the bar represents altitude, the bar representing Han Chinese will be shorter compared to that representing Tibetans since Han Chinese live at lowlands.

What is the role of natural selection in evolution in Tibetanscompared to Han Chinese?

Tibetans and Han Chinese are thought to originate fro. same ancestors.

However, while the Han Chinese lived in lowland areas, Tibetans split off drom the Han Chinese about 2750 years ago and went on to live in high altitudes.

Natural selection helped Tibetans to evolve to adapt to high altitudes with several mutations occurring in their genes which are mostly related to use of oxygen by the body.

Assuming height of the bar represents altitude, the bar representing Han Chinese will be shorter compared to that representing Tibetans.

Answers

Answer:

The research is unethical(fetal stem cells) since the blastocyst, an unimplanted human embryo at the sixth to eighth day of development, is destroyed during the stem cell extraction process.

Answer:

Embryonic Stem Cell Disadvantages

1. Difficult to differentiate uniformly and homogeneously into a target tissue. 2. Immunogenic—ES cells from a random embryo donor are likely to be rejected. after transplantation.

Explanation:

The main disadvantage with embryonic stem cells is the way that they are acquired. Since human embryos are destroyed during the process of harvesting embryonic cells, this makes the research unpopular with those that believe human life begins at conception and that this life is being destroyed.

Which letter kingdom represented would be animals?

B)
C)

Answers

Answer:

F)

Explanation:

Animals are multicellular organisms (that's why we can see them) with a nucleus containing DNA. They consume other organisms. This means they are heterotrophs. Animal cells don't have cell walls. If you look at its cell, there is no cell wall visible. This eliminates options B, C, and E. So, option F would represent animals.

If 15% of a particular DNA strand are nucleotides containing cytosine, what percentage of the DNA molecule would contain thymine

Answers

Answer:

35%

Explanation:

To make a DNA helix, two DNA strands are required. They are connected by the nitrogenous bases on each strand. Each type of nitrogenous base is complementary to another type: cytosine (pyrimidine) pairs with guanine (purine) and thymine (pyrimidine) pairs with adenine (purine). This means they only bond with their pair.

For every cytosine, there must be a guanine bonded to it. So, if 15% of the strand is cytosine, another 15% must be guanine.

Since,

15% + 15% = 30% and 100% - 30% = 70% ,

30% of the DNA strand consists of the cytosine-guanine pair and 70% of the DNA strand consists of the adenine-thymine pair.

Since,

70% / 2 = 35% ,

70% is made up of equal parts adenine and thymine, 35% of the DNA strand must contain thymine.
