Answer: The cell synthesizes mRNA and proteins preparing it for cell division.
Explanation: During this phase the cell also synthesizes enzymes and nutrients for the process of cell division.
Answer:
mRNA
Explanation:
mRNA, the messenger RNA is the type of RNA that serves as a template for synthesis of proteins. mRNA is formed by the process of transcription that occurs inside the nucleus. The mature mRNA leaves the nucleus and enter cytoplasm to join ribosome.
The sequence of the nucleotide of mRNA is read in the form of genetic code and each triplet codon signifies specific amino acid to be added to the newly synthesized protein. For the purpose, the tRNAs deliver the specific amino acids to the mRNA-ribosome complex while rRNA are the structural components of ribosomes.

Answer:
1). Prophase: This known to be the first step of mitosis. This phase is denoted when genetic fibres within the cell nucleus known to be chromatin begins to condense and become tightly compacted together.
2). Metaphase: This is known to be the second stage that follows prophase and prometaphase and progrsses to anaphase. Metaphase starts to occur when once all the kinetochore microtubules get attached to the sister chromatid which is brought about by the force generated.
3). Anaphase: At this phase, the centomeres at the centre of the sister chromatids are severed. It ensures that each chromosome receives identical copies of the parent cell’s DNA.
4). Telophase: This is the last phase of mitosis. It occurs when the newly formed daughter chromosomes get their own individual nuclear membranes and identical sets of chromosomes.
The main purpose of mitosis is to accomplish cell regeneration, cell replacement, and growth in living organisms.
Answer:
Non polar molecule, small
Explanation:
Cell membrane is a selectively permeable membrane.
Factors that affect permeability of a molecule are-
A. Size - Small molecules can easily pass through the membrane than the large molecules.
B. Solubility - Non polar molecules ( eg. carbon dioxide) are lipid soluble in cell membrane , so they can easily pass through the membrane than the polar molecules (eg. glucose)
