Anaphase. In <span>Anaphase the sister chromatids separate from each other to the opposite sides of the cells.
2. </span>
Chromosomes would not separate into two nuclei. <span>Mitosis is a process cell division, where one cell divides into two identical cells.
</span>
3.
Metaphase I. <span>Meiosis prophase I is the phase in which chromosomal crossing over occurs. The phase after prophase I is metaphase I.
4. </span>
Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes. <span>In the gametes, there are half of the number of chromosomes present in the body cell.
5. </span><span>
A species has to adjust rapidly to a changing environment. To adjust to the environment, crossing over is necessary, and it does not occur in mitosis, but meiosis.

50 percent. Parents: Yy x yy
Offspring: Yy Yy yy yy
50 % is Yy and 50% is yy.

One parent had white eyes and the other was heterozygous for eye color. The ratio in the offspring is 50-50. The only possibility is the following:
Parents: Rr x rr
Offspring Rr Rr Rr Rr

Their fur will be a mixture of red and white hairs. The offspring will be heterozygous. They will have alleles for both red and white hairs and both will be expressed.
</span>
9. Not enough information.

Both of the parents' genotype must have been Pp. The genotype of the white plant is pp since it is recessive:
Parents: Pp x Pp
Offspring: PP Pp Pp pp
One of the four is white.</span>
In some skeletal muscles, the
fascicles form a common angle with the tendon. These skeletal muscles are known
as Pennate muscles (also called pinnate muscles or penniform muscles). Generally,
these types of muscles allow higher force production but smaller range of
motion.
Answer:
A. the root is continuing to grow so the cells are going through mitosis
The Hershey and Chase experiments showed that the inherited genetic material was DNA (deoxyribonucleic acids). In this experiment, the scientists labelled the DNA molecule with a radioactive isotope of phosphorus.
Centrifugation causes the separation of different components according to their size. So, by blending, they centrifugated the mixture of virus and the bacteria, which separated the viral protein capsule and the bacteria. Later, they found that the virus infected bacteria contains the DNA of bacteria, not the protein.
Hence, bacterial cultures infected with a virus were agitated in a kitchen blender to separate the protein coat of virus from the bacteria.
