Density is mass divided by volume
Replication - The action of copying or reproducing something.
DNA replication of producing two identical replicas of DNA from one original DNA molecule.
Transcription - First step to gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.
1.) Transcription involved both DNA and RNA, whilst replication only involves DNA.
2.) Replication uses two identical replicas of DNA, whilst transcription is copied.

Answer:
The correct answer will be- primary motor cortex
Explanation:
The motor cortex is the portion of the brain present in the precentral gyrus of the frontal lobe of the brain. The motor cortex is thought to be involved in the planning actions and control voluntary actions.
The motor cortex is divided into three regions: premotor cortex, primary motor cortex and supplementary motor area.
The primary motor cortex is the region of the motor cortex which controls the voluntary movements in the human body by generating the impulse.
Thus, the primary motor cortex is the correct answer.

Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm. They transport proteins from one part of the cell to another. Ribosomes are the protein factories of the cell.

Antenatal clinic is a clinic that is involved in provision of care to pregnant mothers. They are given advise on nutrition that is the food to eat and the ones they are not supposed to eat among other advises. The care is provided by doctors, midwifes and nurses. Pregnancy is divided into trimester namely first trimester ( first 3 months), second trimester (middle three months) and third trimester (last three months of pregnancy). During the third trimester many changes may be observed and the nurses may report the following findings to the provider during this trimester; they include varicose veins, Hemorrhoids and lordosis (change in the curvature of the spine) which are normal however client teaching is recommended. In addition, the findings may include leg cramps (normal) and fainting spells not normal but may be felt when the client is rising.
