Answer:
The answer is pp
Explanation:
Steve and Sonya's son genotype is pp. Because an inheritance of autosomal recessive disorder is with recessive allele responsible for the exceptional phenotype. In this case, Steve and Sonya are both heterozygotes, Pp, which means they both have a p allele because each one gave the boy a p, contributing to affect his son. And since we are talking about inheritance of an autosomal disorder, we know that the parents phenotypic proportions are the same.
The significance of elephants can be characterized as them being a Keystone species. Keystone species are usually considered to be species which have a extremely largy impact on a certain ecological niche or certain environment compared to their relative presence in that environment. In other words, while elephants aren't exactly the most numerous of species, they represent an important element of their environment which also effects other animals.
Answer:
The correct answer is: b. lightening of media in the unsealed tube only.
Explanation:
- According to the question, the bacteria can undergo only aerobic respiration, that is it can produce its energy, that is, ATP, or adenosine triphosphate, only in the presence of oxygen.
- The unsealed tube allowed air or oxygen to pass into it which can be used by the bacteria for its respiration. In the process, it will produce acid that will cause the media colour to lighten.
- The sealed tube do not allow any oxygen to pass into it. As the given bacteria can undergo only aerobic respiration but not anaerobic respiration, in absence of oxygen it will not be able to undergo respiration and produce energy and acid. Hence, the media colour will remain unchanged.
- The control tube is used to check the sterility of the media.
Answer:
Option B, Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.
Explanation:
Options for the question are
A) Apply auxin directly to the shoot tip on the side to which you want the tip to bend.
B) Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.
C) Inject compounds that block auxin receptors into the part of the stem opposite from the direction you want the stem to bend.
D) Plant the roots in two different pots, and apply auxin to the root bucket that is on the same side as the direction you want the plant to bend.
Solution
Auxin is responsible for stem elongation by inhibiting growth of lateral buds. The movement of auxin is opposite to the direction of elongation of cells. Generally, Auxin moves to the dark side which is opposite to the direction i.e the lighter side in which cell elongate . Due to this growth pattern, the stem tip gets curved towards the light.
Hence, option B is correct
