Novay_Z [31]

Answer:

d. Monosomy X is the only viable monosomy known to occur in humans.

Explanation:

Human have 22 pair of homologous chromosomoses and an extra pair of sex chromosomes. While in males  the sex  chromosomes  are X and  Y , females have two chromosomes X . Anyway, in normal conditions the total number of chromosomomes that humans have in their cells is 46 (23 pair of chromosomes).  

Aneuploidy is a biological condition where an individual have an abnormal number of chromosomes in their cells.  In humans for examples, this would be a human having more or less than 46 chromosomes.

The Turner syndrome also called  monosomy X is an aneuploidy  where  one of the X chromosomes is missing in a female.  Although under constant supervision, people with Turner syndrome have viable healthy lives. However this is the only monosomy that occur in humans that is compatible with life.

Proteins around which the long, linear strands of DNA are wrapped; they serve to keep the DNA untangled and to enable an orderly
igor_vitrenko [27]

Answer:

The correct answer is- Histone

Explanation:

DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.

Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.

DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.

I) predict which of the liquids would cause the largest decrease in mass of potato stick
oksian1 [2.3K]

Answer:

1 mol per dm3 sodium chloride solution

Explanation:

The liquid that would cause the largest decrease in the mass of the potato stick would be the one with  <u>1 mole per dm3 sodium chloride solution.</u>

<em>The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.</em>

Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.
