The correct option to this question will be 'C' i.e., Gorilla Gorilla.
As the number of Differences of the amino acids representing for the beta-haemoglobin is less than other 5 species from humans, so we can say that Gorilla is closely related on the basis of molecular data given in the question. The beta Haemoglobin Gene is responsible for coding a protein which is called beta-globin. Each cell present in humans contains two genes of beta-globin.
<span>The trait that is ancestral to all chordates is the presence of a notochord...the others are gill slits and nerve chord</span>
Answer: Sphincter muscles
Explanation:
The circular rings of smooth muscles, that can contract to regulate the movement of the smooth muscles that can contract to regulate the movement of food through the gastrointestinal tract are known as sphincter muscles.
These two layers are outer layer and inner layer. The outer layer is longitudinal and the inner layer is circular. They contract rhythmically to squeeze food.
The answer is <span>A. Meiosis: It increases genetic variation, which helps ensure the species will survive.
Meiosis increases genetic variation. This means there is a great variety of genotypes among the population. Hence, there are organisms able to survive in a wider range of temperature. If </span><span>there were drastic changes in temperature in an ecosystem, some of the organisms will survive because their genotype allows them to live in such conditions. If there were no variety thanks to meiosis, all of the organisms would die. And that is not beneficial to a species.
Imagine on the other hand that mitosis occurred. Mitosis does not provide a variety of genotypes and all of the organism will be the same. </span><span>If there were drastic changes in temperature in an ecosystem, all of the organisms would die because all of them could respond to the change in the same way.</span>
