Which of the following is NOT true of carbon?
A. It is present in all organic compounds.
B. It is a relatively small atom.
C. It will do anything to fill up its electron shell.
D. It can bond with multiple other atoms at once.
Anybody know?

Answers

Answer:

it is b

Explanation:

The characteristic which is not true of carbon is: B. It is a relatively small atom.

Carbon can be defined as a non-metallic and tetravalent chemical element represented with the chemical symbol C and it has an atomic number (number of protons) of six (6). This ultimately implies that, carbon is found in Group 6 of the periodic table because of its six (6) valence electrons, that are found in the outermost shell of its atomic nucleus.

Some of the characteristics of carbon include the following:

It has the ability to form a covalent bond with multiple other atoms at once.It is found in all organic compounds.It does anything to fill up its electron shell.It is a relatively large atom, which allows it bond with multiple other atoms.

Which of the following statements about cellular respiration is true?
A Animals do not carry out cellular respiration.
B Cellular respiration is the process by which some living things take energy from the sun to make food.
C Oxygen is a product of cellular respiration.
D Oxygen is a reactant of cellular respiration.

Answers

Answer:

D

Explanation:

google cell respiration reaction

The statement which is true about Cellular respiration is as follows:

Oxygen is a reactant of cellular respiration.

Thus, the correct option for this question is D.

What is Cellular respiration?

Cellular respiration may be defined as a process through which organisms disintegrate the molecules of glucose in order to derive energy in form of ATP in the presence of oxygen.

The complete reaction of cellular respiration is as follows:

[tex]C_6H_1_2O_6+6O_2[/tex] → [tex]6CO_2+6H_2O+ENERGY.[/tex]

This important reaction is carried out in the cell organelle known as mitochondria. This is because it is known as the powerhouse of the cell by the derivation of energy in the form of ATP. Although this chemical reaction is carried out in the presence of oxygen, it is known as aerobic respiration.

Therefore, oxygen is a reactant of cellular respiration is a statement which is true about Cellular respiration. Thus, the correct option for this question is D.

How does the mean speed of the water molecules change as they are heated

Answers

When the water molecules are heated, the speed usually increases

The average speed of water molecules increases as they are heated, it is due to kinetic energy.

How does water molecule changes due to heating?

When change in temperature, there is also a change in the kinetic energy of the molecule.  If an increase in temperature, the kinetic energy also increases. Thus, the movement of water molecules increases as we heat it up.

If molecules are heated up, it changes the kinetic energy and increases the collision and diffusion rate of the molecule.

When any substance gets heated it gains thermal energy and if cooled it losses thermal energy. If a molecule gets kinetic energy or a water potential is higher than the concentration of water in a system.

Therefore, the mean speed of the water molecules increases as they are heated.

Contact lens solution is salty in order to match your tears. Contact lens solution is ______________ to the cells in your eyes.
Is it hypertonic, hypotonic, or isotonic solution

Answers

Answer:

Its isotonic

Explanation:

Because The contact lenses that we wear have been formulated to be isotonic, which means that they have the same osmotic pressure as the tear film in our eye.

Contact lens solution is salty in order to match your tears, which is isotonic to the cells in the eyes. The correct option is C.

What is isotonic solution?

Isotonic solutions have the same osmolarity (or solute concentration) as other solutions.

Water will flow in equal parts out of each solution and into the other if these two solutions are separated by a semipermeable membrane.

Isotonic solutions are used to increase fluid volume due to blood loss, surgery, dehydration, and extracellular fluid loss.

The contact lenses we wear are isotonic, which means they have the same osmotic pressure as the tear film in our eye's layer of lubricant bathing the cornea and conjunctiva.

The ocular tissues and the water in the lens must maintain equilibrium.

Thus, the correct option is C.
