The disorder can occur anytime
Answer:
True
Explanation:
Lipids are the primary layer of the cell membrane and are classified as hydrophilic head "water loving" and a hydrophobic tails "hates water". This lipids in the cell membrane does not dissolve in water.
<h2>Answer:</h2><h2>Part 1.</h2>
The correct option of 38 question is B which is be the smaller size.
<h3>Explanation:</h3>
As the cell is suspended in salt solution which is hyper tonic as compared to cell.
And salt ions are also not allowed to enter the cell, so the consequence will be the movement of water from cell to salt solution to make cell equal to salt solution.
So the cell will shrink making cell of smaller size.
<h2>Part 2.</h2>
The correct option of 39 question is option B which is cell B will swell more than cell A.
<h3>Explanation:</h3>
- Actually here swelling means the size of cells.
- At the end the size of cell B will be more than the size of cell A. Because the cell A is placed in less concentrated solution than the cell B.
- First glucose will diffuse to cell making cell hypotonic and after that water moves in cell by osmosis.
- Water always move from high concentration to low concentration.
- As in cell A low amount of glucose and water will move in cell than Cell B.
- Hence Cell b will swell more than A.

Answer:
d
Explanation:
becuase it is a organism made of tissues 1
Answer:
- Diploid → Prophase, metaphase, and anaphase
- Haploid → Telophase
Explanation:
During prophase I, chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n
During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n
During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n
In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n
Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.
The two new cells are ready for meiosis II.
