Answer:
Crossing over increases the genetic variation
Errors in crossover formation result in chromosomal rearrangements (duplications and deletions) and may also cause chromosome nondisjunction
Explanation:
Crossing over, also known as recombination, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during meiosis. Crossing over increases the genetic variation of the resulting gametes, allowing different genetic combinations to be passed from parents to offspring. Unequal crossing over is a type of error associated with chromosomal duplication and/or deletion events. Unequal crossing over occurs when homologous sequences are not paired precisely. Moreover, errors in crossing over may also cause chromosome nondisjunction, thereby leading to aneuploidies.
There are exactly 24 chromosomes in a girl cell and 24 in a boy cell.
Answer: teleconferencing
Explanation:
Using peer-to-peer collaboration will not work if the members work at many different locations.
While instant messaging may work, it can be hard to have a meeting this way.
Templates do not apply to this situation.
This leaves us with the answer of "teleconferencing" as you can have a meeting with people online, even when they are far apart.
The answer to the question above is letter D. <span>Chromosomes found in the cell nucleus.</span>
In the cell nucleus, DNA is tightly packed into the
thread-like structure known as chromosomes. Every chromosome is made up of
tightly coiled DNA around proteins (histones) that support its structure.
Chromosomes are not visible when there is no cell division. It cannot be seen
in the cell’s nucleus nor under the finest microscope. They are only visible
when the cell is dividing and is apparently visible under a microscope.
Answer:
electrical energy
The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy.
