How will the movement of water affect a survey if it is transferred from a hypotonic solution to a hypertonic solution?
Inga [223]

Answer:

The cell will shrink

Explanation:

In an hypotonic solution, water moves into the cell through the process of osmosis. This shall be due to the high concentration of water in the hypotonic solution than that in the cytoplasm.

Due to this movement, the cell bulges out.

If the cell is transferred to a hypertonic solution, water shall move out of the cell thereby making the cell shrink. This is because water concentration in the cytoplasm shall be higher than that in the hypertonic solution.

Effect to the survey shall be an experience of the exact opposite of the previous immersion.

Which of the following is a covalent compound?
V125BC [204]

Answer:

Water is a covalent compound.

Explanation:

covalent compounds are individual molecules characterized by the sharing of electrons between two or more atoms. Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled.

Example:

Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), Water (H2O) and iodine monobromide (IBr).

Properties:

1. At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas.

2. Covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.

3. Covalent compounds have lower melting and boiling points.
