How many membranes does the chlorplast have? a. 1 b. 2 c. 3 d. 4

Biology
1 answer:
Pachacha [2.7K]4 years ago
3 0

Answer:

B

Explanation:

Chloroplasts have two membranes: <u>external and internal membrane.</u> These membranes contain 60% of lipids and 40% of proteins, just like the typical cell membranes. The <u>inner or internal membrane</u> is virtually non-permeable to any substances but it has transport proteins, on the other hand, the <u>outer or external membrane</u> is permeable to most of the small molecules

It is projected that an increase in carbon dioxide levels in the atmosphere will MOST LIKELY lead to
babunello [35]

The right answer is higher-than-average sea levels.

With the rise in CO2 level that caused an increase in air temperature and sea surface temperatures. At this time, they were the highest ever recorded. In addition, the rise in mean sea level continued and the extent of Arctic sea ice was well below normal for most of the year.

12 If pressure is applied to a rock until its volume is
mote1985 [20]

Answer: The correct answer to the question is option 2

If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.

Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.

Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.

Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.

This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.

How many new volumes would each new cell contain whenever a cell splits?
Elenna [48]
The specific volume will be different for various kinds of cells. The safe answer would be that the new cell will pretty much have the same volume as the one that it divided from. This is true for most eukaryotic cells unless other factors like epigenetics or mutations come into place.

One example of moments a cell would increase in volume is during hypertrophy. This simply means that the cell is increasing in size (compared to: hyperplasia -- which is an increase in number of the cells). Hypertrophy is definitely an increase in volume of the cell but this doesn't necessarily translate to cell division (i.e. just because the cell is big now, doesn't mean it will still be big when it divides).

Another moment of increasing volume of the cell and now also related to cell division would be during the two stages in the cell cycle (i.e., G1 and G2 phases). This is the growth phase of the cell preparing to divide. However when mitosis or division happens, the cells will normally end with the same volume as when it started.

This are safe generalizations referring to the human cells. It would help if a more specific kind of cell was given.
