Hi lovely,
The answer you're looking for would be the activation or inactivation of genes.
Those cells are called neurons
Answer:
A) The two strands of a DNA molecule are parallel and complementary.
Explanation:
DNA is a polymer of nucleotide and this nucleotide are made up of a deoxyribose sugar molecule, a nitrogenous base, and a phosphate group. In DNA genetic information of the cell is stored in the form of nitrogenous bases.
DNA is double-stranded and both the strands run anti-parallel with each other. This anti-parallel orientation provides the nitrogenous base of one strand to form hydrogen bonds with the nitrogenous base present on the opposite strand.
In DNA adenine base pairs with thymine with two hydrogen bonds and guanine base pairs with cytosine with three hydrogen bonds. So the false statement is A.
Answer;
-Aggressive behavior
Dr. Han is studying what brain structure is associated with aggressive behavior among rats and is most likely to see the amygdala activated when using neuroimaging techniques.
Explanation;
-Aggression is a fascinating and distressing topic for the pet rat owner. We are normally intrigued or amused by aggressive behaviors like chasing and sidling, but we hate it when our pets hurt each other.
-Aggressive behaviors are strung together into sequences that vary in their intensity and duration. The lowest intensity encounters are chases.
When an acetate fiber is cut and is seen under a microscope, the cross section is crenulated shaped. Crenulated shaped cross section is a resultant effect when the external part of the cellular solution solidifies first than the interior of the acetate fiber when taken out rapidly out the acid bath.
