(See figure below, where meiosis I begins with a diploid (2n = 4) cell and ends with two haploid (n = 2) cells.) In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).
Answer:
Because each duplicated chromosome consists of two identical sister chromatids joined at a point called the centromere, these structures now appear as X-shaped bodies when viewed under a microscope. Several DNA binding proteins catalyze the condensation process, including cohesin and condensin.
Explanation:
The nurse should anticipate the use of antiviral comination in the management of this patient ( <span>peginterferon alfa-2a and </span>ribavirin). This will help
reduce further damage to the liver. A repeat test should be conducted to
indicate whether the virus is cleared.
Answer:
A.
Explanation:
bacteria have cell membranes to mimic a normal cell. this protects the bacteria from being consumed by the body's natural defences .
Answer;
As liquid water freezes, the molecules arrange themselves in a way that takes up more space than liquid water. What would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules? A).The density of ice would be greater than the density of liquid water, and ice would not float. B). Ice would form in layers, and liquid water would get trapped in between the layers. Liquid water would have a higher specific heat, making it less likely to undergo vaporization. C).The freezing point of water would decrease, making ice more difficult to form.
