Strengthening some synapses and weakening others establishes neural circuits that contain memories; the low-frequency stimulation of synaptic inputs to a cell can <u>decrease</u> their strength in a phenomenon known as <u>long-term</u><u> depression</u>.
The effect of long-term depression can arise from neural effect of synapses. The synaptic impulses start to decrease gradually when a person is suffering from long-term depression. This decreased neural synapses arise from long-term exposure to stress that is chronic. It can also stem from anxiety. The continuous exposure of the neurons to stress and anxiety can also lead to degeneration and depletion of the cells present in the nervous system. Also the cortisol levels rise during depression and it is regulated by the hippocampus. This leads to a delay or restriction in the developing neurons inside the brain. Long-term depression can lead to increased chances of getting addicted to alcohol or drugs.

The process of cellular respiration transforms the energy in the bonds of glucose into the usable energy for the cell in the form of ATP.
The cellular respiration refers to an alignment of metabolic procedures and reactions, which occurs in the cells of species to transform biochemical energy from the nutrients into ATP and then discharge the waste outcomes.
Answer:
The correct option is : a. Acanthamoeba keratitis
Explanation:
Acanthamoeba keratitis is the infection of the cornea of the eye. This infection is caused by the protozoa Acanthamoeba and can lead to permanent blindness. This disease is very difficult to treat by using conventional medications.
The common medication used in the treatment of this infection is a combination of polyhexamethylene biguanide (0.02% to 0.06% drops) and chlorhexidine (0.02 to 0.2% drops).
Answer:
They are genetically identical to the parents and only differ if a genetic mutation occurs.
Sexual reproduction involves two parents and produces offspring that are genetically unique.
The greater the genetic variation, the better change that an individual in the population have a favorable gene that can help survival. Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population.
Explanation:
<span>When the dna pieces called telomeres get too short, the cell can no longer divide.
</span>We can define Telomeres as they<span> are the caps that are present at the end of each strand of DNA and there function is also that they protect our chromosomes, when they get too short the cell can no longer divide these dna pieces and they die.</span>
