For questions four plants make their own food which is oxygen gas. This oxygen gas, is an important part of the air, the gas that plants and animals must live on. When people breathe, it is oxygen that we take out of the air to keep our cells and bodies alive.
The opening of channels that let positive ions flow out of the cell (or negative ions flow in) can cause hyperpolarization. Examples: Opening of channels that let
+
K
+
K, start superscript, plus, end superscript out of the cell or
−
Cl
−
C, l, start superscript, minus, end superscript into the cell.
The opening of channels that let positive ions flow into the cell can cause depolarization. Example: Opening of channels that let
+
Na
+
N, a, start superscript, plus, end superscript into the cell.
The opening and closing of these channels may depend on the binding of signaling molecules such as neurotransmitters (ligand-gated ion channels), or on the voltage across the membrane (voltage-gated ion channels).
Answer: -20
Explanation:
Here is the equation to solve:
(-107)-(-97)+(-10)
First and foremost, we should note that:
- × - = +
- × + = -
Therefore, (-107)-(-97)+(-10)
= -107 + 97 - 10
= 97 - 107 - 10
= 97 - 117
= -20
Answer:
THE ANSWER IS (Reactants are formed inside the plant, and products are taken in from the environment by the plant. Reactants are taken in from the environment by the plant, and products are formed inside the plant.)
