How does oxygen get into the cell in order for cellular respiration to occur?A.Diffusion
B.Exocytosis
C.Osmosis
D.Endocytosis

Answers

Answer 1

Answer:

Answer:

A. Diffusion

Explanation:

A.Diffusion - this is correct. Diffusion is the process where small molecules enter the cell by moving from a high concentration to a low concentration through a semi-permeable membrane.

B.Exocytosis - this is incorrect. Exocytosis is a cell transport mechanism where the cell uses a system of vesicles to transport cargo outside of the cell. The vesicles fuse to the cell membrane and deliver the cargo outside.

C.Osmosis - this is incorrect, osmosis is a type of diffusion specific to water molecules

D.Endocytosis - this is incorrect. Endoocytosis is a cell transport mechanism where the cell uses a system of vesicles to transport cargo into the cell. The cell membrane engulfs the molecules and brings them into the cell via the vesicle

Which type of bond will form between two chlorine atoms?

Answers

The link between the same atom is always non-polar Covalent.Is Covalent because there is no possibility of an atom donating electrons to the other, since they are equal and need the same number of electrons, and is why the formal charge non-polar (electronegativity) of two atoms is equal. When there is no difference of formal charges (dipole moment) between the atoms, the connection is always apolar.

Which type of reaction produces the most dangerous radioactive waste?

Answers

The correct answer to the question above is fussion of uranium. The fussion of uranium is the only type of reaction in which produces the most dangerous radioactive waste. The fusion of uranium means the binding of their atoms and produce a radioactive waste.

Calculate the pH of a solution that is 0.111 M HCl. PH=?

Answers

HCl(aq) ------> H⁺(aq) + Cl(aq)
↓ ↓ ↓
i : 0.111 M 0 0
v: - 0.111 M +0.111 M +0.111 M
_______________________________
eq: 0 +0.111 M +0.111 M

HCl is a strong acid, so it ionizes 100% in solution :

PH = - log [ H+]

PH = - log [ 0.111]

PH = 0.9546

hope this helps!

How could you safely determine if a base is stronger than an acid?

Answers

Combine the two solutions. If the resulting salt is basic, you know the base was stronger. If you end up with an acidic salt, the acid was stronger.

Answer:

B) Use a conductivity apparatus

Explanation:

I got it right on Plato. Strong acids and strong bases will conduct more than weak acids and weak bases, so you can tell if one is stronger than the other by seeing which one conducts more.
