scientists can test differences of the area with pigmentation by observing which is lighter and which is darker however they use microscope to look the difference of the pigmentation over the cells.
Answer:
Explanation:
Mendel four postulate is Principles of Paired Factors, Principle of Dominance, Law of Segregation which is Mendels First Law of Inheritance and Law of Independent Assortment which is Mendel’s Second Law of Inheritance.
The six possible outcome are,
3. Alleles segregate from each other during gamete formation at anaphase I gene assorts independent of each other during gametes formation.
4. Some genes have dominant and recessive alleles. Allele of a gene can either be dominant or recessive in its form
7. Unit factors occur in pairs , allele of a gene occur in pair
Dominant alleles can become codominant alleles during mitosis, when two allele both finds expression in the phenotype of an organism they are codominant
8. One gene pair separates independently from other gene pairs independent assessment of gene.
5. Different gene pairs on nonhomologous chromosomes will separate independently from each other during meiosis.
When Darwin returned to England aboard the HMS Beagle after his voyage to the Galapagos Islands, he used artificial selection to help gather data to justify his theory of evolution. After studying the finches on the islands, Darwin moved to raising birds, notably pigeons, back home to test his theories.
<h3>What, according to Darwin, is artificial selection?</h3>
Artificial selection is the discovery of desirable qualities in plants and animals by humans, as well as the procedures taken to improve and maintain such traits in future generations.
They may adjust an organism's properties by choosing which creatures were permitted to reproduce. . Darwin referred to this form of alteration in organisms as artificial selection.

An observed consequence of higher water vapor concentrations is the increased frequency of intense precipitation events, mainly over land areas. ... Furthermore, because of warmer temperatures, more precipitation is falling as rain rather than snow.
Answer:
There was no sulfur compound added to the medium, that could be used as an electron donor.
Explanation:
Bacteria that use light for energy requirements mean that they get their energy from photosynthesis and transferring energy through the molecules.
Bacteria play a major part in the reductive and oxidative cycle of the sulfur which is mediated by the help of photosynthetic bacteria, so the sulfur or sulfur compounds are major requirements for their growth in the habitat or the medium.
Thus, the correct answer would be- There was no sulfur compound added to the medium, that could be used as an electron donor.
