Answer:
A
Explanation:
1. All cells, prokaryotic as well as eukaryotic cells divided into two daughter cells by mitotic division. Before division, every cell must replicate their DNA, and makes two copies of their DNA, and finally divide into two daughter cells with equal number of chromosome.
2. Each daughter cell contain equal number of chromosome and same as the parental cell in case of chromosome number .
3. DNA replication occurs in the S phase( synthetic phase) of cell cycle.
Answer: Central Nervous System
Explanation:
The emotions such as pain, happiness, trauma and other sensory things are controlled by the brain. The things that we feel like pain, heat, cold et cetera are also controlled by the brain.
The nervous system has two parts peripheral nervous system and the central nervous system. The pain signals are carried from the knees to the brain by the central nervous system.
The F1 generation differed from the F2 in the Mendel's experiments in that all the F1 generation showed the dominant phenotype, however only three- fourths or three quarters of the F2 generation did. This is because all the F1 generation were heterozygous and thus the dominant phenotype was expressed, while in the F2 generation there was a mixture of homozygous dominant, homozygous recessive and heterozygous. Therefore, the heterozygotes and the homozygotes dominant showed a dominant phenotype.
Answer:
4 amperes
Explanation:
Using the formula; V = IR
Where;
V = voltage (volts)
I = current (amperes)
R = resistance (ohms)
From the formula; I = V/R
According to the information provided in this question, the resistance of circuit (R) is 3 ohms while the voltage (V) produced by the cell in the circuit is 12 volts.
Therefore, I = 12/3
I = 4 A or amperes.
