What would happen if sister chromatids were not pulled apart at anaphase 2​

Biology
1 answer:
olga nikolaevna [1]2 years ago
8 0

Answer and Explanation: Nondisjunction occurs when sister chromatids are not pulled apart at anaphase II. This will cause both sister chromatids/ homologous chromosomes to be pulled to just one pole of the cell.

Since the anaphase I stage in Meiosis I occurred without errors, this would result in four haploid gametes being produced.

However, two of these gametes will be normal, will have the normal number of chromosomes. The other two gametes would have an abnormal number of chromosomes and be aneuploid. One would have n+1 number of chromosomes, and the other would be n-1.

leva [86]

The question is incomplete. Th ecomplete question is as following:

All of the following protect the skin and mucous membranes from infection EXCEPT  

A) multiple layers of cells.

B) tears.

C) saliva.

D) HCl.

E) the "ciliary escalator."

Answer: D) HCl.

Explanation:

  • The epidermis, the outer layer of the skin provides waterproofing and serves as a barrier to infection and other laers also sustain any type of injury.  
  • Tears wash out foreign bodies which enter the eye. In addition, tears contain a substance called lysozyme which has an antibacterial function and works to prevent microbial invasion and infection.  
  • Saliva protects against infection, especially via the innate immune system. This mechanism is an important first-line protection against bacterial and viral infection
  • The mucociliar escalator is within the conducting airways and is composed of mucus and cilia that transfer the mucus up and out of the lungs where it can be removed by coughing or swallowing,

Whereas HCL helps in the digestion process.

Hence, the correct option is D.
