Answer:
4N
Explanation:
Mitosis is the process whereby a cell duplicates or produces another identical copy of itself. The mitotic process, which occurs in four main stages produces two daughter cells that are genetically identical to the parent cell. For example, a diploid organism (2n) will produce two daughter cells with 2n from mitosis.
However, in a case whereby a plant cell (A) screws up mitosis during metaphase and pulls full copies of all chromosomes to one side. This would result in one daughter cell having 4n or tetraploid number of chromosomes. Ideally, mitosis separates the chromosomes equally into the two daughter cells to have 2n each. If one cell has all chromosomes, it means that cell will have all the 4n.
For example, in a diploid human cell with 46 chromosomes (2n). Mitosis should occur in such a way that each daughter cell will have a diploid 46 number of chromosome (2n). However, if all the chromosome ends up in one cell during mitosis, that cell will have 92chromosomes, which is 4n or tetraploidy.
Answer:
First picture (of baby and parents) is reproduction, the third picture (kid at doctor) is growth, I'm not sure about the others.

Answer:
So, the correct answer is 'Cells wall is rigid and does not get overstretched'
Answer:
The correct answer is b RNA polymerase is responsible for unwinding the DNA double helix and for catalyzing the formation of phosphodiester bond between nucleotides.
Explanation:
DNA double helix is unwound by the catalytic activity of helicase or dna B by using the energy derived from the hydrolysis of ATP.
RNA polymerase helps in the polymerization of nucleotides b the formation of phosphodiester linkage present in RNA.
Explanation:
Γ-Aminobutyric acid (GABA) is a non-protein amino acid that is widely present in microorganisms, plants and animals. It is the main inhibitory neurotransmitter in the central nervous system (CNS) of mammals.
It plays the leading role in reducing neuronal excitability throughout the nervous system. In humans, GABA is directly responsible for the regulation of muscle tone.
Although, in chemical terms, it is an amino acid, in the scientific and medical communities they rarely refer to GABA as such because the term "amino acid" by convention refers to the α amino acids and GABA is not. It is also not considered as part of any protein.
In spastic diplegia in humans from an early age, GABA absorption is negatively affected by the nerves damaged by the lesion in the upper motor neurons characteristic of the condition which leads to the development of muscular hypertonia signaled by those nerves that are incapable of absorbing GABA.
