Answer:

Changes in gene expression

Explanation:

This phenomenon is the result of changes in gene expression. That means, how the information in the DNA is used by the cell. The genes that are active in the cells of the brain will be very different from the genes that are active in the cells of the bone marrow.

These patterns of gene expression are different for each cell, and dictate the identity of that cell. Gene expression patterns are controlled by a variety of factors in the cell that allow tissue-specific expression, such a transcription factors.

This can also be facilitated by another layer of regulation called epigenetics, which literally means "on top of" genetics, and refers to modifications of DNA (and the proteins around it), that can reflect and influence the activity of the genes within.

What organ lies on the outer wall of the testes within the scrotum?
shutvik [7]
The answer is the epididymis. It is a contracted, tightly-coiled tube linking back of the testicles to the deferent duct (vas deferens). The epididymis contains three parts and these are the head, body, and tail. The head of the epididymis is positioned on larger pole of testis. It stocks sperm for maturation.

Roman55 [17]

AlohaS4

Answer & Explanation:

( Rh Factor ) represents the presence of the Rhesus protein in the blood.

( Rh+ ) blood contains the rhesus protein.

( Rh- ) blood does not contain the rhesus protein.

( Type O ) blood is the universal donor.

( Type AB ) blood is the universal recipient.

( Rh+ ) blood can receive Rh+ or Rh- blood.

( Rh- ) blood can receive Rh- blood.

Hope you found this helpful! <3

What could be the consequence of a mutation that changes the sequence of nucleotides in a promoter?
Korolek [52]

Answer:

The changes in the sequence of nucleotides present within a promoter is a prime cause of the defected transcriptional regulation, which may eventually result in disease. However, not every modification within the sequence of a promoter influences the regulation of transcription, it relies upon the nature and the location of the genetic defect.  

When a mutation results within the sequence of a promoter region it may hamper the usual procedures of gene stimulation by affecting the step by step alignment of the transcription factors at the promoter region. Therefore, as a consequence, a mutation within the sequence of a promoter may result in the enhancement or reduction in the level of mRNA and thus protein.
