This scientific law is called as Law of conservation of energy.
Sun is the primary source of energy .Energy once produced by the sun is then utilized by the organisms at various tropic levels. The energy is transferred from one organism to another. Energy is neither created nor destroyed. This is called as law of conservation of energy. Plants uses sunlight and make food and the energy is then transferred to organisms eating it. When the organism dies the energy is released into the environment. This cycle continues and the the law of conservation of energy is maintained.
There was less of it, making it more possible for the species to be extinct.
Answer:
See the second attached image showing the gametes from the parent with the location of the centromere indicating the type of chromosome
Explanation:
According to the position of the centromere, chromosomes can be of 4 types namely:
- Metacentric
- Acrocentric
- Telocentric
- Sub-metacentric
A metacentric chromosome is a chromosome that has no short or long arm. The arms are equal in length with the centromere joining the two sister chromatids located at the center.
Acrocentric chromosomes have unequal arm lengths with the centromere skewed towards one end of the chromosome.
Telocentric chromosomes have their centromeres at one end of the chromosome.
Sub-metacentric chromosomes have unequal arm lengths but the centromere is not as skewed to one end of the chromosome length as found in acrocentric chromosome.
The only possible gamete from <em>aa bb</em> parent is <em>ab</em>. Recall that the allele <em>a </em>is located on a metacentric chromosome while allele <em>b </em>is located on acrocentric chromosome.
Hi, the answer to this question would be an Molecular Clock. A molecular clock is a technique used by researchers that uses mutation rates in DNA to estimate the length of time that two species have been evolving independtly. Hope this helped :)
