chubhunter [2.5K]

Answer:

The correct answer is C. be more likely to have cancer at some point in his/her life.

Explanation:

Cell cycle checkpoints are controlled by different proteins which are coded by different genes. They are important in cell cycle regulation and stops cell cycle immediately if they find any problem in the cell like mutation.

The cell cycle will not be continued if the problem does not solve and cell death will occur which prevents cancer by preventing the mutation to spread into new cells.  

Therefore if a mutation occurs in certain genes that enforce a checkpoint on the cell cycle then the mutated gene will pass in new cells and the mutated cells will grow uncontrollably due to no checkpoints so the person will probably have cancer at some point in his or her life.

Earth is the largest terrestrial planet in the solar system. Earth's huge size enables it to exert enough gravitational force to
denpristay [2]

Answer:

Lower gravitational force due to lower mass.

Explanation:

Mars has lower gravitational force than Earth because of its lower size because mass has a direct effect on gravitational force of an object. Earth has mass of 5.972 × 10^24 kg which is 10 times greater than mass of Mars which is 6.4171 x 10^23 kg. So due to earth's more mass, it has more gravitational force than planet Mars which has lower mass than earth.

What happens if the correct ligand binds to ligand-gated sodium channel in a post-synaptic neuron?
Maru [420]

Answer:

Post-synaptic neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.

Explanation:

Postsynaptic neuron :

These are the neurons that is present after the gap called synapse. These neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.

There are number of neurotransmitter. These includes

GABA ergic: This neurotransmitter is often inhibitory.

glutamatergic: This neurotransmitter is often excitatory.

Adrenergic: This neurotransmitter releases norepinephrine.

Cholinergic: This neurotransmitter activates vertebrate neuromuscular junction.
