b. Mitosis.
c. Meiosis.
d. Transcription.

Answers

Answer 1
Answer:

Alleles undergo segregation ispresent in the mitosis. The answer is B. The first stage is prophase. Thenucleolus disappears and the two centrosomes begin to form the mitotic spindle.The spindle xtends between two opposite poles f the cell. Next is the metaphase.The centromeres of the chromatid pairs align at the center of the mioticspindle. Then anaphase, the centromeres will split that separates the chromatidpair. In here, alleles are formed. They are now called chromosomes. The lastphase is the telophase. The chromosomes will then form a thread-like chromatinand for ache envelope, a nucleoli appears.

Answers

Answer:

1. cerebellum

2. brainstem

3. cerebrum

4. cerebrum

5. brainstem

6. cerebrum

7. cerebellum

Explanation:

The cerebellum is a region of the brain located behind the top part of the brainstem, which coordinates voluntary movements (e.g., posture, balance, coordination, speech). The cerebellum is well known to regulate the balance of the body. The brainstem is a type of automatic control center that connects the cerebrum with the spinal cord. The pons represents a group of nerves that serve as connection between the cerebrum and cerebellum. The pons are located in the brainstem (between the midbrain and the medulla oblongata). The cerebrum is the largest part of the brain and can be divided into right and left hemispheres. These hemispheres communicate with each other by the corpus callosum.
