The accurate statements are: Meiosis produces genetically diverse cells, Meiosis increases genetic variation in the offspring, and Meiosis produces haploid cells from diploid parent cell. The inaccurate statements are: Meiosis increases genetic content in daughter cells, and Meiosis maintains original number of chromosomes in parent cell.
The following statements accurately describe the outcome of meiosis:
These statements inaccurately describe meiosis:

Answer:
A) Meiosis produces genetically diverse cells.
B) Meiosis increases genetic variation in the offspring.
C) Meiosis produces haploid cells from a diploid parent cell
Explanation:
Through crossing over, meiosis produces genetically diverse cells causing more genetic variation of offspring. The Daughter cells in meiosis are formed from a diploid cell that has all 46 chromosomes, however the daughter cells are haploids as they need to join with the other gamete to have a full set of chromosomes.
Answer:
The population of each bacteria in 1, 2, 3 are 12, 8, and 7 respectively.
Explanation:
From the given information:
For food source A; we have:
3P₁ + P₂ + 2P₃ = 58 units of food A ---- (1)
For food source B; we have:
2P₁ + 4P₂ + 2P₃ = 70 units of food B ---- (2)
For food source C; we have:
P₁ + P₂ = 20 units of food C ----- (3)
From equation (1) and (2); we have:
3P₁ + P₂ + 2P₃ = 58
2P₁ + 4P₂ + 2P₃ = 70
By elimination method
3P₁ + P₂ + 2P₃ = 58
-
2P₁ + 4P₂ + 2P₃ = 70
P₁ - 3P₂ + 0 = - 12
P₁ = -12 + 3P₂ ---- (4)
Replace, the value of P₁ in (4) into equation (3)
P₁ + P₂ = 20
-12 + 3P₂ + P₂ = 20
4P₂ = 20 + 12
4P₂ = 32
P₂ = 32/4
P₂ = 8
From equation (3) again;
P₁ + P₂ = 20
P₁ + 8 = 20
P₁ = 20 - 8
P₁ = 12
To find P₃; replace the value of P₁ and P₂ into (1)
3P₁ + P₂ + 2P₃ = 58
3(12) + 8 + 2P₃ = 58
36 + 8 + 2P₃ = 58
2P₃ = 58 - 36 -8
2P₃ = 14
P₃ = 14/2
P₃ = 7
Thus, the population of each bacteria in 1, 2, 3 are 12, 8, and 7 respectively.
Repulsion between negatively charged backbone of DNA double helix van der Waals interaction
Interaction between water and carbonyl oxygen of guanine hydrogen bond
Answer:
Interaction between hydrophobic (nonpolar) amino acid side chains is due to hydrophobic interactions.
Repulsion between negatively charged backbone of DNA double helix is due to electrostatic repulsion forces.
Interaction between water and carbonyl oxygen of guanine is due hydrogen bonding
Explanation:
The hydrophobic effect refers to the tendency of non-polar substances forms aggregates in an aqueous solutions in order to avoid interactions with water molecules. This results in a favorable entropy increase.
For non-polar amino acids, hydrophobic interactions are important in stabilizing their structure wherein they are densely packed within the core of a protein while those with with polar groups are found in the exterior.
The phosphate backbone of DNA is negatively charged. Since like charges repel, therefore, electrostatic repulsion forces of the ions are responsible the repulsion of the backbone DNA double helix.
Hydrogen bonds are formed between electronegative oxygen atoms and hydrogen atoms of neighboring molecules due to the partial negative and positive charges on each of the atoms.
This hydrogen bonding is responsible for the interaction between water and carbonyl oxygen of guanine as the hydrogen atoms of the water molecules are attracted to the oxygen atoms of the guanine molecules due to the partial charges on each of the atoms.
