Answer: The correct answer for the blank is- d. inhibitory neurotransmitter.

Neurotransmitters are the chemical messengers in the body, which are released by the axon terminal of neuron ( also called nerve cell) and transmit nerve impulse to the neighboring cell ( which could be a muscle cell or a nerve cell) .

There are primarily two types of neurotransmitters that are-

1) Excitatory neurotransmitter and 2) Inhibitory neurotransmitter.

Inhibitory neurotransmitter have inhibitory effects on the neuron that is they reduce the chances that a neuron will fire an action potential. In other words, they are responsible for slowing signals between neurons.

Example- The most common inhibitory neurotransmitter is GABA ( gamma amino butyric acid)

Explain what friction corollas and a low pressure gradient does to an air parcel?

Kipish [7]

Answer with Explanation:

Coriolis Force - refers to the fictitious force that acts perpendicularly to the direction of a rotating motion.

Air parcel - refers to a body of air that is "imaginary."

Pressure gradient - the change in pressure across a given distance.

Pressure gradient force - the net force that is being directed from high pressure to low pressure.

When an air parcel is at rest, the pressure gradient force acts upon it. It will then move from high pressure to low pressure.

However, when the air parcel starts to be in motion, its direction will be changed with the help of the Coriolis force. Thus, it moves to the right side of the Northern hemisphere.

Once the speed of the wind increases, the change in direction of the air parcel increases. This happens until the pressure gradient force and the Coriolis Force are equal in magnitude. When this happens, the wind will start blowing parallel to the points of equal pressure. The wind will now then be referred to as in "geostrophic balance."

When friction happens, the geostrophic balance breaks. The flow of the wind will be slowed down. This means that the Coriolis force will also be lessened. The air parcel will then move towards the lower region.

In fruit flies, straight wings are dominant and curly wings are recessive. What will the generations look like? Assume that Mend

anzhelika [568]

Answer:

The P generation has straight wings and curly wings.

The F1 generation has all straight wings.

The F2 generation has straight wings and curly wings.

Explanation:

This question involves a single gene coding for wing shape in fruit flies. The allele for straight wings (S) is dominant over the allele for curly wings (s). This means that allele "S" will mask the phenotypic expression of allele "s" in a heterozygous state.

According to the question, the cross follows all Mendel's method of crossing two true breeding parents with opposite traits. Hence, the parent generation (P generation) will be between a truebreeding straight wings parent (SS) and a truebreeding curly wings parent (ss). (See attached image for full cross).

Since the straight wing allele (S) is dominant, all the F1 offsprings will possess straight wings with the genotype: Ss, which is heterozygous.

If this F1 offsprings are self-crossed i.e. Ss × Ss, four possible offsprings in the phenotypic ratio 3 straight wings : 1 curly wing will be produced in the F2 generation. The offsprings will possess the following genotypes: SS, Ss, Ss, and ss.

Offsprings SS, Ss, and Ss will all be phenotypically straight-winged

Offsprings ss will be phenotypically curly-winged.

In overall, this means that P generation has both straight and curly wings (SS and ss), F1 generation has only straight wings (Ss), F2 generation has both straight and curly wings (SS, Ss and ss).

What is an endocrine function? (Apex)

ElenaW [278]

The correct answer is option D

the pineal gland releases melatonin into the bloodstream

In the exocrine system the organ releases certain substance other than hormone while in the endocrine system , the organs releases hormones.

In option D, melatonin is a hormone released by pineal gland and thus it is an endocrine function

Which populations would benefit the most from the presence of decomposers?

Dafna11 [192]

I'm guessing there was answer choices to this problem? regardless I think I know the answer to it. Plant populations would benefit the most of the presence of decomposers due to the fact that decomposers release nutrients into the soil when they break down things.
