A plant can have either brown (B) or red (b) leaves. Brown is the dominant
Marizza181 [45]

Answer:

The plant would be red.

Explanation:

It would be red because red leaves are a recessive trait which has lowercase b's so if the genotype for the plant is bb, it would be red. If the plant had BB, it would be brown and if it had Bb it would be brown but, it would be a carrier of the red gene.

The main problem that your central nervous system will try to solve is how to get out of this place.

<h3>B. What is the somatic nervous system probably doing?</h3>

It is releasing stimuli so that the pupil dilates and the blood goes to the muscles, to give greater physical vigor.

<h3>ç. Which part of the autonomic nervous system is likely to be active and what is it doing?</h3>

The autonomic nervous system is a part of the nervous system that functions independently of will and consists of neurons that conduct impulses from the central nervous system (brain and/or spinal cord) to the glands, smooth muscle and heart muscle.

<h3>What are the physiological responses of adrenaline binding in the sympathetic autonomic system?</h3>

Adrenaline increases the overall activity of the heart, increasing both the heart rate and the force of contraction. The heart has β1 receptors in both contractile and specialized myocardium. When turning on, a series of cardiac effects can happen.

With this information, we can conclude that the main problem that your central nervous system will try to solve is how to get out of this place.

True or false: In a gel electrophoresis gel, a DNA fragment containing 100 bp (base pairs) would travel faster (and further) tha
vova2212 [387]

Answer: true

Explanation: In gel electrophoresis, the smaller the size/molecular weight of DNA the faster it moves across the gel and vise versa. This is as a result of the pore size of the gel which is usually prepared 1g of agarose in 100ml of distilled water. So a DNA fragment with 1000 base pairs will "struggle" its movement across the gel pore making it mive less faster and further. Movement and molecular weight of DNA are inversely proportional.
