Olenka [21]

This membrane mimics the plasma membrane that is around animal cells. In order to explore how water moves in and out of a cell, one cell was weighed and then submerged in hypertonic solution. The other egg was weighted and submerged in hypotonic solution. It was predicted that the egg submerged in hypertonic solution  would decrease in mass. It was predicted that the egg submerged in hypotonic solution would increase in mass.

Explanation:

The outermost covering of an animal cell is the plasma membrane. It is a selectively permeable membrane that allows only selective molecules to pass through it.

A solution having higher concentration of solute than the cell cytoplasm is called a hypertonic solution.

A solution having lower concentration of solute than the cell cytoplasm is called the  hypotonic solution.

The movement of water molecules from the region of its higher concentration to the region of its lower concentration through a semipermeable membrane is called osmosis.

A cell placed in hypertonic solution will undergo exosmosis so it will lose water and its mass will decrease.

A cell placed in hypotonic solution  will undergo endosmosis of water  so it will gain water and its mass will increase.

The effects of deforestation include: increased soil fertility, as without trees to absorb them, the essential mineral nutrients
Nitella [24]

Answer:

Harm to downstream fisheries, due to sedimentation of waterways from increased soil erosion.

Explanation:

Deforestation is the reduction of forest area in a given territory, both because of nature or man-made causes.  It results in the loss of habitats for many animal and plant species, the destruction of natural peoples' habitats and livelihoods, and increases soil erosion and large floods in valleys. Often, a previously forested area becomes waste land.

The formation of what three classes of substances cause double displacement reactions to occur
Lera25 [3.4K]
The three substances that cause a double displacement reaction to occur are:
(i)   Ionized compounds. These are usually water.
(ii)   A gas that bubbles out a solution.
(iii)  A precipitate.

In double displacement reaction is where two new compounds are formed when two parts of two compounds switch places. For example; when sodium chloride combines with silver nitrate, the two new compounds formed are Sodium nitrate and silver chloride reason being sodium and silver switched places.
