Answer:
Metaphase ⇒ Chromosomes line up in the middle of the cell
Prophase ⇒ DNA condenses to form chromosomes
Anaphase ⇒ Each chromosome separates and moves to opposite ends of the cell
Telophase ⇒ Nuclear membranes form around each set of chromosomes
Answer:
(a) crossing over: Meiosis I, Recombination
(b) chromatids separate at their centromeres and migrate to opposite poles: Meiosis II, Anaphase II
(c) chromosomes become aligned in pairs at the equator: Meiosis II, Metaphase II
Explanation:
Homologous recombination is a type of genetic recombination that occurs during meiosis (formation of ovum and sperm cells). The paired chromosomes of the male and female parents are aligned so that similar DNA sequences intersect. This crossing over produces an exchange of genetic material, which is an important cause of the genetic variability observed in the offspring.
Meiosis II: Anaphase II. The centromeres separate and the daughter chromatids - now individual chromosomes - move to the opposite poles of the cell. The centromeres separate, and the two chromatids of each chromosome move toward the opposite poles in the spindle.
Meiosis II: Metaphase II. Chromosomes are accommodated in the equatorial plate of metaphase, similar to what happens in mitosis. They are attached to the already fully formed meiotic spindle. Each chromosome is aligned in the equatorial plate of the metaphase, as it happens in mitosis.
Answer:
I would say B is the answer.
Explanation:
An applied force is a force that is applied to an object by a person or another object. Example: pushing a box to the other side of a room.
A normal force is a force that surfaces exert to prevent solid objects from passing through each other. Example: resting a book upon a table.
Drag is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This doesn't really match the force we use.
However, an attractive force is a force by which one object attracts another. Example: two magnets pulling/colliding together. This is a good example of a force we exert on objects when it is pulled toward us.
