Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, one similar substance that, if missing, many cycles (particularly the two cycles/processes provided in the question) will not exist/proceed is the sun/sunlight.
In the water cycle for instance, if there is no sun/sunlight, there will be no heat to allow for evaporation of water from the water-body (ocean, sea, stream or lake) hence there will be no cloud of water droplets in the atmosphere. The implication of this is that, the first process of the water cycle will not proceed, hence the cycle will not exist.
During photosynthesis, carbondioxide reacts with water in the presence of sun/sunlight to produce glucose and oxygen. The absence of sun in this reaction will not lead to the production of glucose which is the useful product of photosynthesis for plant.
From the explanation above, it can be deduced that <u>the absence of the sun/sunlight will prevent the two cycles from existing</u>.
Cancer cells are created by mitosis. Mitosis is cell division. I don’t understand your question
Explanation:
The 47,XXY karyotype of Klinefelter syndrome spontaneously arises when paired X chromosomes fail to separate (nondisjunction in stage I or II of meiosis, during oogenesis or spermatogenesis
<h3><u>Answer;</u></h3>
Meiosis is called reduction division <u>because number of chromosomes in daughter cells is reduced to half than that of parent cell.</u>
<h3><u>Explanation;</u></h3>
- Meiosis is a type of cell division that takes place in the germ-line cells, it involve division of a parent cell into four daughter cells.
- The process of meiosis involves two divisions of the genetic material, namely; meiosis I and meiosis II.
- <em><u>The first division is called the reduction division or meiosis I, this is because it reduces the number of chromosomes from 46 chromosomes or 2n to 23 chromosomes or n.</u></em>
The small molecules that chain together to form a protein molecule are called amino acids an example of which could be glycine
