75%
Explanation:
The real answer is 80% and 75% is closest so uhm yea
Answer:
C) primary cell wall --> plasma membrane --> cytoplasm --> tonoplast
Explanation:
When a potassium ion moves from the ground into a vacuole of a plant cell, it must pass through the different structures that are part of it.
First, the outermost layer of the cell is the cell wall. Plant cells may have a primary and a secondary wall, but the latter is not always present. The primary wall is always located outwards (and in the case of having a secondary wall, it will be located between the primary wall and the plasma membrane).
Then, inside the cell wall, we will find the plasma membrane (also called plasmalemma).
When crossing the membrane, the ion will be in the cytoplasm of the cell and will be directed towards the vacuole, which is surrounded by its membrane called tonoplast. The vacuole is an organelle that has no definite shape, although it is always surrounded by the tonoplast, and it contains different substances such as water and enzymes.
Answer: Two molecules of H2A
Explanation:
Structural organization of nucleosomes were determined by isolating them from unfolded chromatin and it has been found that the basic units of chromatin are the nucleosomes which consist of histone octamers of two molecule each of histone H2A and other histone molecules like H2B, H3 and H4. The histones are wrapped around with 147bp of DNA in almost two (2) turns.
Answer:
Water leaves the cell by osmosis, the cytoplasm pulls away from the cell wall and the cell becomes flaccid making the plant wilt
Answer:
Binary fission
1. Forms two daughter individuals
2. Divides only once
3. No residue is left
4. Takes place in favourable conditions
5. Immortality is present
Example: Amoeba reproduces by binary fission
Multiple fission
1. Forms many daughter individuals
2. Divides repeatedly
3. Residue is left
4. Takes place in favourable as well as unfavourable conditions
5. Immortality is absent
Example: Plasmodium reproduces through multiple fission
