Meiosis is a type of cell division that occurs in cells and this division results in a reduction in the number of parent cells by half.
A parent cell with 23 pairs of chromosomes (46 chromosomes) undergoing meiosis will result in the production of 4 cells each with 23 single chromosomes.
In meiosis, a beginning cell with 23 pairs of chromosomes (after duplication) will go through the first division separating all homologous chromosomes and giving rise to two cells with 23 chromosomes each with its own two sister chromatids.
During the second division, each of the two daughter cells produced divides and the chromosomes separate at the centromeres, with each chromatid moving to opposite pole, so four daughter cells is produced and contains 23 single chromatids/chromosomes.

b. nucleic acids
c. lipids
d. proteins
Answer:
D is the correct answer.
Explanation:
proteins are the carbon compounds or biomolecule that helps in formation of muscles and bone and controls cell processes. Thus option D is correct.
What are Biomolecules?Biomolecules are involved in the maintenance and metabolic processes of living organisms.
Carbohydrates are polyhydroxy aldehydes or ketones.
They are classified as monosaccharides, oligosaccharides and polysaccharides based on number of constituting sugar units obtained upon hydrolysis.
Proteins are polymers of amino acids arranged in the form of polypeptide chains, it can be classified into primary, secondary, tertiary and quaternary structure.
For example, Myosin is the protein which involve in contraction of muscles.
Nucleic acids are the genetic material found in the cell. These are up two types such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Its function is to help in transfer of genetic information and synthesis of proteins by transcription and translation.
Lipids are water insoluble organic molecule, include fats, waxes, sterols, fat-soluble vitamins, phospholipids, etc.
Thus option D is correct.

The measurement of the pressure gradient of two solutions that are separated by a selectively permeable membrane is called...
A. Osmolarity
B. Equilibrium
C. Homeostasis
D. Tonicty
The osmotic gradient, which is the concentration difference between two solutions on either side of a semipermeable membrane, is used to determine a particle's concentration in a solution. Thus, Option A is correct.
What is osmolarity of a solution?Osmolarity, which is determined by the number of osmosis of a solute per liter of solution, is a gauge of solute concentration.
According to their relative osmolarity, solutions can be broadly characterized as hypertonic, hypotonic, or isotonic.
Osmolarity is important because cells cannot survive if their environment's osmolarity is significantly different from their own.
From a lower osmolarity to a greater osmolarity, water flows over a membrane. It switches from the diluted to the concentrated side, to put it another way.
Therefore, osmolarity measurement of the pressure gradient of two solutions that are separated by a selectively permeable membrane.
