Answer:
2(h - 8) - h = h - 16 2. 4(x - 3) + 5 = 1 3. 70 = -7(-2 -2z) 4. -2x + 4 = 2(4x-3)-3(-8+4x
Explanation:
2(h - 8) - h = h - 16 2. 4(x - 3) + 5 = 1 3. 70 = -7(-2 -2z) 4. -2x + 4 = 2(4x-3)-3(-8+4x
Answer:
600 kcal
Explanation:
In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.
Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.
A more kind of fighting state, it will try new ways to attack the squirrell
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.
