Which of the following ways are leftover neurotransmitters cleaned up if they

Biology

Alisiya [41]3 years ago
5 0

Answer:

The correct answer is -

the neurotransmitters are broken down in the synapse

The presynaptic neuron absorbs the neurotransmitters

Explanation:

The termination of the neurotransmitters is essential as if they can cause harm by continuing the stimulus effect on the muscles or cells. To clean up these neurotransmitters there are two ways- Degradation of neurotransmitters with the help of enzymes in the synapses or synaptic cleft and the presynaptic neurons absorbs or suck up neurotransmitters. The neuron (presynaptic neuron) is that releases the neurotransmitter like dopamine, serotonin, is the one that re-uptake it.

This reuptake is done by transporter proteins that are are symporters in nature as these proteins pump neurotransmitters as well as ions back into the neuron.

You are given two true-breeding groups of rabbits. The first group has floppy ears and white coat color. The second group has st
malfutka [58]

Answer:

Option E, Floppy ears are dominant over straight ears; coat color is determined by incomplete dominance

Explanation:

Let the allele for floppy ears be "F" and the allele for straight ears be "f"

And Let the allele for black coat color be "B" and the color for white coat color be "b"

Now, the cross is carried out between the first group having floppy ears and white coat color (FFbb) and the second group having straight ears and black coat color (ff BB)

The 16 offspring have genotype FfBb

Phenotype of 16 offspring is Floppy ears and grey coat

Ff represents the floppy ear , thus "F" is dominant over "f"

Bb represents the grey color which is a case of incomplete dominance in which none of the real trait i.e black or white is expressed.

Hence, option E is correct

It has been said that life could develop on Earth only because Earth is just the right distance from the sun. Any closer, and it
blondinia [14]

Answer:

The correct answer will be- the planets and moon also exhibit hydrothermal vents, volcanoes and rocks.

Explanation:

Scientists have always tried to understand and explain the origin of life on Earth and predicted that life on earth originated as a result of the conditions created by the distance of the Earth from the Sun.

Later discoveries found that life exists even in the harsh conditions on Earth-like hydrothermal vents and inside sub-surface of the rocks. This shows that life can exist in extreme conditions.

Since the planets other than Earth posses such hydrothermal vents, rocks and volcanoes, therefore scientists predict that life could be found on other planets.

An antibody has been isolated that binds to F-actin but not to G-actin. What structural feature(s) of F-actin do you suppose the
galina1969 [7]

Answer:

F-actin is a double helical filament as opposed to G-actin,which is a globular protein .Each actin filament has two ends,called the plus and

the minus ends, which makes it recognizable from each other.This gives the structure a distinct polarity.

Explanation:

Actin is the most abundant protein that is found in almost all eukaryotic cells.Its a most important part cytoskeleton as its a monomeric subunits(size 42kDa) of two types of filaments i.e. microfilaments and thin filaments in cells. Actin is essentially required to maintain stability and morphogenesis of cell.It is involved in numerous significant processes such as endocytosis,cell division and migration.Actin is present in two forms:

•G-actin

•F-actin

The two forms of actin are different structurally.

G- actin is a globular shaped protein,usually present in free form(a monomer),having a tight binding site for another actin monomer.Each monomer has ATP. Upon polymerization of G-actin monomers, a polymer called F-actin filaments is form. This process is driven by hydrolysis of ATP.
