The greenhouse effect is the effect where carbon dioxide (usually from factory gas emissions, car exhaust gas, etc) gets sent into the Earth's atmosphere , however, instead of disappearing, it gets trapped under the atmosphere of the Earth and cause the temperature of the planet to rise. The temperatures rise since the radiation of the sun's rays gets trapped under the layer of carbon dioxide. This affects climate change since when the globe warms up, our earth begins to warm up too resulting in colder parts of the earth to rise in higher temperatures than usual.
The essential amino acids cannot be produced in the human body and hence these amino acids have to be obtained through the diet. Hence these amino acids have this characteristic that these cannot be produced in the human body and have to be obtained through diet this makes them essential. Hence those nine amino acids are considered as the essential amino acids.
Answer:
A. They have different genetic sequences but are found in the same location on a chromosome.
Explanation:
In genetics, alleles are the variant form of a gene. According to Mendel, there are usually two alleles for most genes except for few cases where there are multiple alleles. Each allele of a pair is contributed by each parent during sexual reproduction. For example, in a gene Tt, the alleles are T for tallness and t for shortness.
Alleles of the same gene are related in such a way that they have different genetic sequences but are found in the same location on a chromosome. The different genetic sequences makes them alternative form of each other.
