Biology

Iteru [2.4K]3 years ago

Answer:

all of the above

Explanation:

Epigenetic alterations are modifications of the genome transmitted during cell division, which do not involve changes in the DNA sequence, are hereditary and are capable of modifying gene expression. In addition, they are temporary modifications that allow DNA to be transcribed and have the ability to move histones to open or close a chromosomal region. There are three main mechanisms of epigenetic alterations: DNA methylation, histone modifications and genomic imprinting.

guapka [62]

Answer:

My hypothesis is that the Hawaiian Island chain was formed by a hot spot in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. My data supports my hypothesis because as the plate moved over the hot spot, the islands that make up the Hawaiian Island chain were formed.

How does the uterus prepare itself to receive a fertilized egg?
frez [133]
The fertilized egg begins a rapid descent to the uterus. The period of rest in the tube appears to be necessary for full development of the fertilized egg and for the uterus to prepare to receive theegg. ... At the end of this transition period, the embryo becomes a mass of very organized cells, called a blastocyst.
