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.

If the frequency of an allele is 0.75, how many copies of this allele should be in a population of 300 diploid individuals?
Ray Of Light [21]

I have provided the options below:

a. 150

b. 225

c. 300

d. 450

e. 75

Answer:

150

Explanation:

Hardy-Weinberg law states, the allelic frequencies of a gene that is, q and p follow the relationship p^2+q^2+2pq = 1, if the population is in equilibrium.

Therefore p^2+q^2+2pq = 1, can be used to calculate the percentage of the allelic frequencies i.e. p^2 and q^2

Allelic frequency = 0.75.

Therefore, the percentage of the allele in the population would be given by

0.75^2 = 0.5625 = 56%.

And the total number of individuals with this allele in the population:

number of individuals = 56×300÷100

= 168 or

150 nearest figure.

Which of the following exposure factors will produce the greatest receptor exposure?
earnstyle [38]

400 mA, 70 ms is the following exposure factors will produce the greatest receptor exposure.

C: 400 mA, 70 ms

<u>Explanation:</u>

As SID builds, the introduction rate diminishes and receptor presentation diminishes. SID and the mAs required to keep up the introduction to the IR have a straightforwardly corresponding relationship (as the SID builds, the mAs required to keep up presentation to the IR increments by a corresponding sum).

An expanded SID likewise decreases amplification (size twisting). The most extreme SID ought to be utilized when conceivable to limit amplification. Infrequently, however, the SID can be purposefully diminished for amplification. SID influences size yet not shape twisting.
