Compare the properties of the parent and daughter cells in mitosis and meiosis and explain the reason for any differences.
MariettaO [177]

1. Mitosis takes place within somatic cells (cells that make up the body). Meiosis takes place within gamete cells (sex cells). 


2. One single division of the mother cell results in two daughter cells. Two divisions of the mother cell result in four meiotic products or haploid gametes. 


3. A mitotic mother cell can either be haploid or diploid. A meiotic mother cell is always diploid. 


4. The number of chromosomes per nucleus remains the same after division. The meiotic products contain a haploid (n) number of chromosomes in contrast to the (2nd) number of chromosomes in the mother cell. 


5. It is preceded by an S-phase in which the amount of DNA is duplicated. In meiosis, only meiosis I is preceded by an S-phase. 


6. In mitosis, there is no pairing of homologous chromosomes. During prophase I, complete pairing of all homologous chromosomes takes place. 


7. There is no exchange of DNA (crossing-over) between chromosomes. There is at least one crossing-over or DNA exchange per homologous pair of chromosomes. 


8. The centromeres split during anaphase. The centromeres do separate during anaphase II, but not during anaphase I. 


9. The genotype of the daughter cells is identical to that of the mother cells. Meiotic products differ in their genotype from the mother cell. 


10. After mitosis, each daughter cell has exactly same DNA strands. After meiosis, each daughter cell has only half of the DNA strands

3.Explain how energy from the sun can eventually be used for active transport in the alimentary canal
Marianna [84]

Answer:

See the answer below

Explanation:

First of all, the radiation energy from the sun is converted to chemical energy by green plants in a process known as photosynthesis. The equation of the process is represented below:

6CO_2 + 6H_20 + (radiation) -->C_6H_1_2O_6 + 6O_2

The chemical energy is locked up as carbohydrate in the green plants. When humans or any other animal consumes green plants or any of their products, the carbohydrate is broken down through a process known as respiration. The equation of the process is as below:

C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + energy

<u>The locked-up energy - usually in the form of ATP - becomes available to be used for various metabolic processes in the body, including active transport in the alimentary canal.</u>

<em>In some cases, humans or animals generally do not consume green plants directly. They consume organisms that consume green plants. Such humans are still able to extract some of the energy through respiration and use it for their metabolic processes.</em>
