Answer;

Alleles are passed from the parents’ sex chromosomes to the sex chromosomes in the offspring.

Explanation;

-Sex linked traits are traits that are carried by the sex chromosomes and inherited together.

-Gene exists in alternative forms called alleles and each allele for a trait is inherited from each parent.

-Sex traits, like the other traits, are passed from parents to off spring through the process of sexual reproduction.

<span>The right answer for this question is C - sex-linked traits are inherited through alleles, which are passed from the parents' nonsex chromosomes to the sex chromosomes in the offspring. This means that the child will have a combination of both parents' nonsex chromosomes.</span>

Disruption of axonal transport would be a good target for his drug.

<h3>What is disruption of axonal transport?</h3>

Axonal transport defects are among the early molecular events leading to neurodegeneration in mouse models of amyotrophic lateral sclerosis (ALS).
Gene expression profiles indicate that dynactin-1 mRNA is downregulated in degenerating spinal motor neurons of autopsied patients with sporadic ALS.
Disruption of axonal transport also underlies the pathogenesis of spinal muscular atrophy and hereditary spastic paraplegias.
The neurotoxin β,β′-iminodipropionitrile (IDPN) selectively disrupts slow axonal transport without affecting fast anterograde or retrograde axonal transport.
Impairment of slow axonal transport causes a proximal accumulation of neurofilaments.
Because neurofilaments regulate axonal diameter, this accumulation leads to a marked swelling of the axon.
Acrylamide causes decreased axonal transport, also causing proximal accumulations of neurofilaments and swelling.

What are the functions and vessels of the heart, and what are some cardiac disorders that might be life-threatening to a person

zavuch27 [327]

Answer:

The cardiovascular, or circulatory, the system supplies the body with blood. It consists of the heart, arteries, veins, and capillaries. but the things that might be life-threatening to a person or animal are;

Explanation: angina is a type of chest pain that occurs due to decreased blood flow into the heart this can harm animals and people. there is also - - - arrhythmia,which is or an irregular heartbeat or heart rhythm,

- congenital heart disease, in which a problem with heart function or structure is present from birth.

-coronary artery disease, which affects the arteries that feed the heart muscle.

- Heart attack, or a sudden blockage to the heart’s blood flow and oxygen supply this can kill. heart failure, wherein the heart cannot contract or relax normally,

- dilated cardiomyopathy, a type of heart failure, in which the heart gets larger and cannot pump blood efficiently and the last one is

- hypertrophic cardiomyopathy, in which the heart muscle walls thicken and problems with the relaxation of the muscle, blood flow, and electrical instability develop

these are only a few that can harm or even kill a living thing like and animal or person these things are really harmful.

I hope this helps you!!

In an experiment, the membrane potential of a neuron is hyperpolarized to –120 mV. When an inhibitory neurotransmitter is applie

denis-greek [22]

Answer:

The inhibitory transmitter activates ligand-gated potassium channels

Explanation:

When a cell is in hyperpolarized state,the potassium gated channels are taken longer time to close up, Therefore, more K+ leaks out of the axoplasm to the exterior.Therefore the cell appears to continue in the resting state, with more negative value of the cell potential of (-120 mV) and this called hyperpolarization.

However, with the addition of inhibitory transmitter,the ligand-gated potassium channels are activated,Theses channels closes up.Then sodium gated channels, which were initially in refractive state reopens, sodium ions diffuses inwards for depolarization, and the neuron returns to depolarized state.
