Answer:

XYY, spermatogenesis.

Explanation:

Non disjunction may be defined as the phenomena in which the sister chromatids are unable to separate during the cell division. Non disjunction can occur in both meiosis and mitosis.

The determination of non disjunction is not possible. But the XYY condition in an individual might occur when the homologous chromosomes of Y are unable to separate during the process of spermatogenesis as Y chromosome is present in males only.  

Thus, the correct answer is XYY and  spermatogenesis

The primary growth of a plant is due to the action of the ________.
goldfiish [28.3K]

The correct answer is A. Apical meristem

Explanation:

In plants, the primary growth refers to the type of growth that increases the length of the stem or toots in opposition to the secondary growth in which the stem thickens and that occurs as the result of the vascular cambium. However, in the case of primary growth, this can be explained mainly due to the action of apical meristem that is a type of tissue located in the tips of roots and the stem and therefore the type of tissue in which the growth takes place mainly through cell division. Considering this, it can be concluded primary growth is due to the action of the apical meristem.

You are a molecule of CO2. Write your autobiography. Tell how you started at glucose and ended where you are today as carbon dio
statuscvo [17]

Answer:

I started out as glucose, got converted to pyruvate, after which I got oxidised by Oxygen to become CO2

Explanation:

My name is CO2, and I started out as glucose from pure honey. I got eaten by a little child when I was two weeks old, and I had to go through the dreadful process of aerobic respiration in the child's body.

My glucose molecules were broken down into pyruvate, and I stayed that way  for a while, as I made my way to the mitochondria of the child's cells.  Once I got to the mitochondria, I met my old friend oxygen, who reacted with me to turn me into the molecule I am today - C02.

If you want to know how I escaped the child's body, that's easy - I simply snuck out his nose while he was breathing one cold dark night.
