The question is incomplete, the complete question is;

Each sentence describes potential and kinetic energy at various locations on a slide. Complete each statement by selecting the position of the object on the slide.

An object at position has all kinetic energy. A B or C

An object at position has all potential energy. A B or C

An object at position has about half potential energy and half kinetic energy. A B or C

Answer:

An object at position C has all kinetic energy.

An object at position A has all potential energy.

An object at position B has about half potential energy and half kinetic energy.

Explanation:

Lets take a good look at the image.

At position A, the object is stationary and we know that the energy possessed by an an object by virtue of its position is known as potential energy. Hence at A, the energy possessed by the body is all potential.

At position B, the total mechanical energy of the object becomes potential energy + kinetic energy as the object is now in motion.

At position C, the object is still in motion and the energy is all kinetic.

Glycogen ________. Glycogen ________. forms the regulatory molecules known as enzymes serves as a structural component of human
jasenka [17]

Answer:

Glycogen in an important storage polysaccharide found in animal tissues.

Explanation:

Full question:

Glycogen ________

A) forms the regulatory molecules known as enzymes

B) serves as a structural component of human cells

C) helps to protect vital organs from damage

D) is an important storage polysaccharide found in animal tissues

E) contains the genetic information found in cells

Glycogen is a complex polysaccharide of glucose founded in humans, animals, fungi and even bacteria. In humans, the glycogen is made and stored in liver cells. In the center on glycogen molecule, there is a single protein called Glycogenin. It is a center of a big flower made of glucose molecules (please refer to the scheme attached - Glycogenin is red and the blue lines are glucose chains). Glycogen is also stored in skeletal muscle, red and white blood cells, in glial brain cells and kidneys but in a smaller amounts. It can be found in the placenta in pregnant women where it serves as a nutrient storage for embryo. In an adult, the liver weighs 1,5 kg and glycogen weighs about 120g in such a liver. After a meal, the level of sugar is rising and the insulin is being secreted. Insulin is a tool by which sugar is being delivered to the cells, like a food delivery. During this period, glycogen is being synthesized in the liver out of glucose residues. When the meal is digested, the sugar level is back to normal. When more energy is needed, glycogen from the liver is broken down by glycogen phosphorylase and the new sugar is released into the bloodstream.

Which answer is the best comparison of the physical sciences to the life sciences. A. Physical science is the study of energy an
Yanka [14]

Answer:

A. Physical science is the study of energy and inanimate matter. Life science is the study of living organisms.

Explanation:

Sciences can be grouped into physical science and life sciences. PHYSICAL SCIENCE is a branch of science that involves the study of energy and inanimate objects i.e lifeless. Physical science encompass the following: physics, chemistry, astronomy, geology etc.

On the other hand, LIFE SCIENCES, as the name implies, is the study of living organisms. It is also referred collectively to as BIOLOGICAL SCIENCES and it includes aspects such as biology, botany (plant), zoology (animal), microbiology (microbes), biochemistry etc.

How many Mg atoms are presented in 3.00 moles of MgCl2
ella [17]

Answer:

1.81 x 10²⁴ atoms

Explanation:

To find the number of atoms in the given number of moles, we need to understand that every substance contains the Avogadro's number of particles.

More appropriately, a mole of any substance will contain the Avogadro's number of particles which is 6.02 x 10²³ atoms

 So;

           If 1 mole of a substance  = 6.02 x 10²³ atoms;

               3 mole of MgCl₂ will contain 3 x 6.02 x 10²³ = 1.81 x 10²⁴ atoms
