Inside the seed there are is an embryo the baby plan and cotyledons. When the seed begins to grow, one part of the embryo becomes the plant while the other part becomes the root of the plant.
Answer:
B) if two species are closely related.
Explanation:
DNA analysis is used to determine the relationship between two species in order to check their relations with each other because DNA molecules has all the information about the organisms. If there is more similarities between two organisms so they are more closely related to each other while on the other hand, if there is no similarities between two species so we can say that there is no relationship exists between two organisms or species. All this discussion describes the usefulness of DNA analysis.
Answer:
The tall parent was heterozygous
Explanation:
If tall height is dominant to short height the only genotype possible for short height is hh, while there are two possible genotypes for tall height, Hh and HH. When HH is crossed with hh all the offspring are Hh, but if Hh is crossed with hh, a quarter of the offspring is HH, a quarter is hh and half is Hh. If the tall pea plants were HH there would only be tall offspring, but because there are some short offspring we know that the tall pea plants must have a genotype of Hh.
I think a frameshift mutation that occurs very early in a protein sequence would have an effect on the structure of the protein such that the primary, secondary, and tertiary structures would be altered. A frameshift mutation occurs when a protein is drastically altered because of an insertion or a deletion. Insertions and deletions cause a change in the length of a gene, which causes a shift in the codon reading frame.
The heart of a lazy person pumps blood less efficiently than an athlete who has trained and prepared to achieve a high performance, this can be understood with the example of football players who will play in other countries that have a higher altitude than the country of origin and has to go before to get used to the rarer air
