Answer:

Parts of human heart and its role and functions are explained below in details.

Explanation:

The heart is a muscular organ about the dimension of a hand, positioned just back and slightly left of the breastbone. The heart elevates blood through the system of veins and arteries called the cardiovascular arrangement.

The heart has four chambers:

  • The right atrium receives serum from the veins and elevates it to the right ventricle.
  • The left side atrium carries oxygenated blood from the lungs and elevates it to the left ventricle.
  • The right ventricle takes blood from the right atrium and elevates it to the lungs, where oxygen is filled.
  • The left ventricle elevates oxygen-rich serum to the remainder of the body. The left ventricle strong contractions produce our blood pressure.

For most runners, momentum is easier to keep steady than to get back up to pace after stopping and starting again.
lisov135 [29]

The correct answer is Option A. - True .

A property of a moving body that determines how long it takes to come to rest when subjected to a constant force is called momentum .

<h3>Explain momentum ?</h3>
  • It is measured by "mass velocity," because momentum depends on velocity, and it also depends on the direction of the body's motion.
  • Momentum is a vector quantity because velocity is a vector and mass is a scalar quantity. Momentum equals mass multiplied by velocity.
  • Momentum is simply a quantity of motion. Quantity is measurable in this case because if an object is moving and has mass, it has momentum.
  • If an object does not move, it does not have momentum. However, it is important in everyday life, but many people are unaware of it.

Which food has the greater nutritional density of vitamin C: (a) an 8-ounce (237 ml) serving of orange juice that contains 125 m
Fantom [35]

Answer: (a) an 8-ounce (237 ml) serving of orange juice that contains 125 milligrams of vitamin C and has 111 calories

Explanation:

Nutrient density or nutritional density reflects the ratio of the nutrient content to the total energy content of the food. Therefore the nutrient density is expressed in terms of the amount of a specific nutrient (in weight) per 1000 calories or joules

Comparing the nutritional density of the two drinks;

(a) For an 8-ounce (237 ml) serving of orange juice that contains 125 milligrams of vitamin C and has 111 calories(111/1000 Kcal) or 0.111Kcal

nutritional density = 125mg/0.111Kcal = 1126.126 mg/Kcal

(b) For an 8-ounce serving of a sport drink that contains 175 milligrams of vitamin C and has 250 calories(250/1000 Kcal) or 0.250Kcal

nutritional density = 175/0.250Kcal =700 mg/Kcal.

Therefore, an 8-ounce (237 ml) serving of orange juice that contains 125 milligrams of vitamin C and has 111 calories has a greater nutritional density of Vitamin C <em>than an 8-ounce serving of a sport drink that contains 175 milligrams of vitamin C and has 250 calories.</em>

What type of energy does food give you?
Olegator [25]

Answer:This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
