Answer:
cloning, Finn-Dorset, DNA, nucleus
Explanation:
So basically what they're doing here is they're taking the cytoplasm of a cell of the Scottish Blackface sheep (maybe a lamb?, whatever)/removing the nucleus inside that cell and instead inserting the nucleus of the Finn-Dorset sheep. Then they insert that "integrated" cell (so to speak) into a surrogate ewe so that the blastocyst can evolve and develop into Dolly (the lamb/sheep).
The process is cloning. The resulting offspring would be genetically identical to the Finn-Dorset (sheep/lamb) b/c the nucleus is coming from that sheep & the nucleus has the genetic material (DNA). Hope ya found this helpful :)
P.S. Oh yeah, and thanks for the fifty points (hopefully)
Answer:
Provides cell structure.
Explanation:
The proteins which have amino acids within them provide cell structure.
Answer:
4. Warm air from the inside moving toward the cold air outside.
Explanation:
A cold draft can be defined as the process in which a current of cold air is being drawn in from the outside. Also, it involves the process in which a current of warm inside air exits or leaves a building through an opening.
This ultimately implies that, when you open the door to your house on a cold day, you would feel a cold draft as a result of the movement between the warm air from the inside moving toward the cold air outside. The warm air that were trapped inside your house would escape through the door due to a difference between the outside (cold) and inside (warm) atmospheric pressure.
Hence, a difference in temperature and atmospheric pressure between the outside and inside air usually causes a cold draft.
<em>Additionally, air typically moves or travels from a region of high pressure to a region of lower pressure. </em>
Meiosis is referred to as reduction division as it divides the chromosome number in half. Crossing over or recombination is the main reason of shuffled genes and increased genetic variation in gametes in meiotic cell division as the homologous pairs are paired up during prophase.
<h3>What is crossing over?</h3>
Crossing over is referred to as the exchange of genes of DNA between paired homologous chromosomes. It actually occurs during the development of egg and sperm cells i.e., during meiosis.
It is an enzyme-mediated step, in which the exchange of genetic material takes place between non-sister chromatids of homologous chromosomes.
It actually occurs at the pachytene stage of prophase I of meiosis cell division.
Thus, it can be concluded that the crossing over is the main reason of shuffled genes and increased genetic variation.
