Answer:
I think the answer the will be option
a) the cells form long vertical tubes
Explanation:
This is because xylem transports water and minerals throughout the plant and they are long and vertical tubes
Answer:
She should look for a cell wall outside the cell membrane.
Explanation:
Answer:
B. As the distance between loci increases, some multiple crossovers go undetected such that the relationship between recombination frequency and map distance ceases to be linear.
Explanation:
When calculating recombination frequencies, and hence, map distances, we might notice that these distances are not completely additive. They might vary. <em>For example, let us say that we have three genes, A, B, and C, in that order. </em>We calculated that the <em>distance between A and B equals 5.9</em> MU and that <em>B and C are 19.5 MU apart.</em> According to this, we might say that the <em>total distance between A and C is 25.4 MU (5.9 + 19.5). </em>However, after a<em> two-point calculation between A and C, the value equals 23.7 MU. </em>
The recombination frequency between these two genes located in the extremes and far apart underestimate the actual genetic distances between them because there might occur other crossing-overs that were not detected. This is <em>when calculating the distance between A and C, we probably will not detect the occurrence of a double recombinant between them, and hence, we might sub-estimate the real distance.</em>
The relationship between the actual map distance (number of crossing overs) and the recombination frequency between two loci, is not lineal. The farther apart are the two genes, the worse is the distance estimation.
<h2>Cell Analogy</h2>
Explanation:
As we see that parents control everything in the house. Similarly,the nucleus controls everything in the cell.
A door is analogous to the cell membrane because it allows people come and go. Similarly,the cell membrane in a cell can allow certain things to enter and exit.
The cytoplasm fills the space in a cell. It is similar to air which is filled everywhere in the house.
- Nuclear membrane: Security guard
The nucleus in a cell is protected by nuclear membrane. The nuclear membrane is analogous to secuity guard. As people in a house are protected by security guard, similarly nucleus is protected by nuclear membrane.
- Endoplasmic reticulum: Hall ways
Endoplasmic reticulum transport things to other places in the cell. It is similar to hallways which help us to reach different places in the house.
The golgi bodies modify,sort and package proteins.
It send them to other parts of the cell when needed.
It is similar to a Car which transports people and can store stuffs.
The mitochondria in a house is analogous to Stove as it breaks down nutrients and turns them into energy. Similarly, the Stove in our house, cooks foods and it is converted into energy when consumed.
The ribosomes are a cell structure that make protein. It is same as a kitchen in our house where people make food or proteins.
I just got this question on my test, the answer is D) glycogen. All excess glucose is stored long-term in the liver and muscle cells as glycogen when animals need it for energy.
