Explanation:
The carbon cycle explains how carbon is made available to life forms. The main processes of the carbon cycle are photosynthesis, respiration, decomposition, natural weathering of rocks and burning fossils fuels so (Option A) is not part of it
Answer:
<em>The correct option is C) 28</em>
Explanation:
Sex cells divide by the process of meiosis. Meiosis can be described as a type of cell division in which the daughter cells formed contain half the number of chromosomes as the parent cell. This is because when the sex cells from the female and male parent will unite then the zygote will possess the right number of chromosomes.
In the following scenario, the sperm cells of the Russian dwarf will contain 14 chromosomes which will unite with the egg of another Russian dwarf also having 14 chromosomes. As a result, a zygote will be produced having 28 chromosomes.
Is this a true of false question? If so, then the answer would be false. Not all have a short life span.
Answer:
chromosomes
Explanation:
DNA of organisms is organized into one or more thread-like structures called chromosomes. Chromosomes are made of DNA and its packing proteins. During cell division, the thin mass of chromatin which in turn is made of DNA and its packing protein condense and becomes visible as individual chromosomes. The DNA molecule is wrapped around histone proteins to form nucleosomes which in turn become compact into chromatin fibers.
The further condensation of looped domains formed by the coiling of chromatin fiber forms chromosomes. The part of a chromosome that holds its two arms together is called centromere. Chromosome becomes visible during the prophase stage only when condensation of chromatin takes place.
