Answer:

The correct answer will be option C- increase the surface area.

Explanation:

At the neuromuscular junctions, the axons of the motor-neurons become bulbous at terminals. These bulbous enlargements are known as the synaptic knobs. The synaptic knob is the bulbous enlargements of the axon present at the terminals. These knobs increase the volume of the axon terminals embedded with the ligand-gated channels and accumulation of neurotransmitters in vesicles.

The motor end plate is the region of the muscle fiber which is responsible for initiating the action potential in a muscle. The motor end plate becomes ruffled or shows small folds or clefts to increase the increased surface area for the neurotransmitter to act.

Thus, option C is the correct answer.

Casts are often designed to keep you dry. An infection or skin irritability may result from a moist cast. Casts made of fiberglass or plaster with standard padding are not waterproof. Cover your child's cast with two layers of plastic and secure it with a rubber band or piece of duct tape to keep it dry during baths or showers.

How do you take care of a plaster cast?

Keep the plaster cast clean and dry at all times.

The cast usually dries completely in 48 hours. Allow it to dry naturally and keep it away from direct heat.
Avoid bumping or hitting the cast.
Do not paint the cast. This will close the pores of the plaster. Having friends decorate the cast using markers is OK.

Recommended daily allowance (RDA) is the nutritional requirement and uptake of the food. One has to eat 7 oranges each week so as to meet the requirement.

RDA is the recommended daily allowance that defines the level of the essential nutrients that a person consumes for a healthy lifestyle that is defined by Food and Nutrition so as to meet the required nutrient amount.

Given,

RDA of vitamin C = 60 mg/day

100 gm orange = 70 mg Vitamin C

So for one week, it is calculated as:

7 × 60 = 420 mg

The vitamin C in 100 gm oranges = 0.0007 and 1 oz = 28.3495 grams.

So, 3 oz = 3 × 28.3495 grams = 85048.5 mg

The amount of vitamin C in 85048.5 mg is calculated as:

0.0007 × 85048.5 = 59.53 mg

Number of oranges to be consumed each week = 420 ÷ 59.53 =7

Therefore, 7 oranges must be consumed in a week.

In order to treat children with attention deficit hyperactivity disorder, methylphenidate is employed (ADHD). They can focus better and it aids with hyperactivity and impulsive conduct. Additionally, people with ADHD or narcolepsy are treated with it (a sleep disorder).

Only prescriptions are accepted for methylphenidate. It is available as early release or prolonged release pills and capsules. To assist their ADHD, some kids might require both prolonged and rapid release methylphenidate.

Answer: dependency is more likely in cultures where access to alcohol is carefully controlled.

Explanation:

Studies have shown that in cultures where access to alcohol is carefully controlled and viewed as a sign of adulthood, dependency is more likely than in cultures where alcohol is used in religious and ceremonial activities.

This has been put down to people tending to abuse alcohol when they get access to it as opposed to cultures where it is readily available.
