And the answer is A. worm
The birds can eat with the worms.
It will help you.
Answer:
Correct answer is D.
Explanation:
Silent mutations have no observable effect while neutral mutations does not cause harm or benefit the organism in any way. Missense mutations are single nucleotide changes that only affect one codon and one protein. In this case answer is frameshift mutation because this type of mutation is result of DNA insertion or deletion which changes the way DNA sequence is read and may affect more than one gene.

Answer:
G1 phase: 2C
S phase: 4C
G2 phase: 4C
Meiosis-I: 2C and Meiosis-II: C
Mitosis: 2C
Explanation:
Let's suppose that a cell with 2C DNA content enters the cell cycle. As the G1 cell with 2C content would enter the S phase, DNA replication would double the amount of DNA. Therefore, the cell by the end of the S phase and in the G2 phase would have 4C DNA.
If the G2 cell with 4C DNA enters meiosis-I, separation of homologous chromosomes to the opposite poles in anaphase-I would reduce the DNA content to 2C. Therefore, the cell by the end of anaphase-I would have 2C content. Meiosis-II would further reduce the DNA content in anaphase-II by separation of sister chromatids to opposite poles. Therefore, each of the four daughter cells formed by the end of meiosis would have C DNA content.
If the G2 cell with 4C DNA enters mitosis, separation of sister chromatids to opposite poles in anaphase would reduce the DNA content. Therefore, each of the two daughter cells formed by the end of mitosis would have 2C DNA content.
The answer is transmission electron microscope.
A compound light microscope is not useful in observing structures inside the cells because they have not as high resolution as a scanning electron microscope and a transmission electron microscope. The latter two give much higher resolution, but the scanning electron microscope allows the study of the surface of the objects. So, it would not be possible to look at the internal structures of the cell on the scanning electron microscope. On the other hand, the t<span>ransmission electron microscope allows studying a very thin cross-section of the cell. It is best for looking at internal structures of the cell, including organelles.</span>
