Q: What does the body derive from the breakdown of the carbohydrate-containing foods and drinks we consume? Read this paragraph and choose the correct option from the provided answers: Regulation of Blood Glucose Levels by Insulin and Glucagon Glucose is required for cellular respiration and is the preferred fuel for all body cells. The body derives glucose from the breakdown of the carbohydrate-containing foods and drinks we consume. Glucose not immediately taken up by cells for fuel can be stored by the liver and muscles as glycogen, or converted to triglycerides and stored in the adipose tissue. Hormones regulate both the storage and the utilization of glucose as required. Receptors located in the pancreas sense blood glucose levels, and subsequently the pancreatic cells secrete glucagon or insulin to maintain normal levels. Choices: - insulin - lipids - amino acids - glucose A:
glucose

Q: Which of newton's laws states that the quantity of angular momentum in a closed system is fixed? Read this paragraph and choose the correct option from the provided answers: The third conservation law is conservation of angular momentum. This vector quantity is the product of rotational velocity and rotational inertia. In any closed system (including the universe) the quantity of angular momentum is fixed. Angular momentum can be transferred from one body to another, but cannot be lost or gained. If a system has its angular momentum changed from the outside it is caused by a torque. Torque is a force applied at a distance from the center of rotation. Choices: - fourth conservation law - sixth conservation law - second conservation law - third conservation law A:
(Answer)
third conservation law

Ques: Q: What is the name of artificial barriers that people build to protect shorelines? Read this paragraph and choose the correct option from the provided answers: Only a tiny fraction of the ocean floor has ever been studied. Why? Humans can't travel deep below the water's surface without special vehicles. The pressure of the water is too great. Total darkness and extreme cold make it even more difficult. That's why people have worked for decades to invent technology for studying the ocean floor. Choices: - seawalls - domes - outcroppings - breakwaters A:
Ans: breakwaters

Q: What are solutions that maintain a relatively constant ph when an acid or a base is added? Read this paragraph and choose the correct option from the provided answers: Buffers are solutions that maintain a relatively constant pH when an acid or a base is added. They therefore protect, or "buffer," other molecules in solution from the effects of the added acid or base. Buffers contain either a weak acid (HA) and its conjugate base (A) or a weak base (B) and its conjugate acid (BH+), and they are critically important for the proper functioning of biological systems. In fact, every biological fluid is buffered to maintain its physiological pH. Choices: - gases - water - liquids - buffer A:
(A).
buffer

Ques:Q: What molecule consists of two atoms of hydrogen and one atom of oxygen? Read this paragraph and choose the correct option from the provided answers: Water is an example of a common chemical compound. As you can see in the Figure below , each water molecule consists of two atoms of hydrogen and one atom of oxygen. Water always has this 2:1 ratio of hydrogen to oxygen. Like water, all compounds consist of a fixed ratio of elements. It doesn't matter how much or how little of a compound there is. It always has the same composition. Choices: - carbon monoxide - hydrogen peroxide - air - water A:

Ans:water

Ques:Q: How many types of galaxies are there? Read this paragraph and choose the correct option from the provided answers: Galaxies are divided into three types, according to shape. There are spiral galaxies, elliptical galaxies, and irregular galaxies. Spiral galaxies are a rotating disk of stars and dust. In the center is a dense bulge of material. Several arms spiral out from the center. Spiral galaxies have lots of gas and dust and many young stars. Figure below shows a spiral galaxy from the side. You can see the disk and central bulge. Choices: - one - five - two - three A:

Ans:
three
