Answer:
The answwer is letter E.
Explanation:
Embryos. Because land plants evolved from aquatic green algae. The transition was easy because of the amount of traits that allowed the survival of the specie. One of these traits was the embryo, which is so essential that every land plants are known as embryophytes.

Explanation:
Answer:
16 feet, 20 feet, and 12 feet
Explanation:
Uppercase allele = 6 feet
Lowercase allele = 2 feet
First, let us look at the outcome of the cross between AaBB and aaBb.
AaBB x aaBb
Progeny:
4 AaBB = 6+2+6+6 = 20 feet
4 aaBB = 2+2+6+6 = 16 feet
4 AaBb = 6+2+6+2 = 16 feet
4 aaBb = 2+2+6+2 = 12 feet
<em>The heights expected in the progeny are 16 feet, 20 feet, and 12 feet.</em>
Answer:
D) The encoded protein contains four repeats of a specific sequence.
Explanation:
The polymerase chain reaction is a technique used to replicate or amplify the amount of DNA sample.
The technique employs running the DNA samples on the gel through which the DNA samples run based on their sizes.
The large-sized DNA fragment runs to a less distance whereas the small-sized DNA run to a large distance.
In the given question, four sizes of DNA bands are formed in the ratio of 1:2:3:4 which shows that the proteins encoded by this DNA have four repeats of a specific sequence of the template strand. This was confirmed when the largest band sample was again used as a sample of PCR and the PCR resulted in the four bands in similar 1:2:3:4.
Thus, Option-D is the correct answer.
