CHROMATIN : It can be simply referred to as genetic material in loose or normal form. It can be DNA or RNA inside the plant or animal cell's nucleus.
2. CHROMOSOME : When the chromatin material is condensed prior to the cell division and get highly organized form that can be visible in form of proper structures have two chromatids, they are called chromosomes.
The process of formation of chromosomes from chromatin occurs mainly in prophase of Mitosis or Prophase II or Prophase I of Meiosis.
3. CHROMATID : Chromatid is also referred to as sister chhromatids since there are two chromatids present in one chromosome that are almost similar. Chromatids can be considered as arms of chromosomes which are attached at a point centromere (please see the image for better understanding).
Hope it help!
It depends on the period. It could be Catherine the Great.
Answer:
An enzyme-substrate complex is a temporary molecule formed when an enzyme comes into perfect contact with its substrate.

Answer:
Explanation:
This question seeks to test the knowledge of the modern synthetic theory of evolution. This theory describes <u>evolution as the changes occurring in the allele frequency within a population of the same specie</u>. Hence, the following questions derived from the question can be answered as thus
1) Does the population evolve instantly from that stochastic event?
YES. This is because the frequency of the allele changed.
2) Can it be said that Natural Selection is at work in this case?
YES. The synthetic theory of evolution derives great "evidence" from natural selection because the allele frequency is believed to have changed because of the environmental impact (the rock) and that the next generation will adapt better to such an environment.
3) How does the Synthetic Theory of Evolution help answer this question?
Previously, evolution was believed to occur over several generation which ultimately lead to some phenotypic changes as a result of adaptive changes in the genes. This old description of evolution would have made one arrive at a wrong answer if one does not consider the modern synthetic theory of evolution which talks about instant evolution from allele frequency (as was described in the question).
