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

MariettaO [177]3 years ago

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

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms, including a high fever, headaches, and
monitta

Answer:

lytic, because of the quick onset of symptoms after infection

Explanation:

As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.

The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.

Peripheral resistance depends on all of the following factors except __________.
pantera1 [17]

Options for the question have not been given. They are as follows:

blood vessel length

blood viscosity

blood vessel diameter

blood colloid osmotic pressure

Answer:

blood colloid osmotic pressure

Explanation:

  • Peripheral resistance is the resistance to blood flow by blood vessels.
  • It is directly proportional to blood vessel length as more the distance to travel, more will be the resistance.
  • It is also directly proportional to blood viscosity as more energy is required to push viscous material.
  • It is indirectly proportional to blood vessel diameter. More the diameter of the vessel, easier it is for the blood to pass.
  • However, it does not depend on blood colloid osmotic pressure. Colloid osmotic pressure is created by the protein components of blood and they do not have any direct impact on blood flow.
