A fertilized egg cell will start to specialize other type of cell in the body because thats when the baby starts to develop and develop organs and organ systems and .... O.0 i think
petrified fossils -> date sedimentary rocks, this will be more precise but Carbon 24 dating would probably a very reliable way of gathering information too
The correct answer is to reduce harmful emissions.
Hydrogen is a chemical element with atomic number 1, this signifies that it exhibits one electron and one proton. Hydrogen gas (H2) is an odorless, colorless, highly combustible and tasteless gas. The hydrogen fuel refers to a zero-emission fuel that discharges no waste components, which can pollute the environment, this is the most likely reason that the US government made such an investment.

1. B, D and J.
2. A and C.
3. E, F, G, H, AND I.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
A membrane is a thin layer which forms the wall of the cell and typically controls what leaves and enters the cell.
Some of the effects of various biological conditions on membrane physiology are;
1. Makes RMP (Resting Membrane Potential) Less Negative: this simply means that it decreases RMP;
- Decreased concentration of leaky potassium channels in the membrane.
- ATP stores are declining through mitochondrial poison (arsenic).
- Increased concentration of leaky sodium channels in the membrane.
2. Influences the Ability of the Cell to Repolarize;
- Voltage regulated potassium channels are blocked.
- Acetylcholine esterase concentration is decreased.
3. Influences the Ability of the Cell to Depolarize;
- The size of the synaptic cleft is increased.
- Hyperhydration (high water concentration in ECF).
- Release of excitatory neurotransmitter by a presynaptic input is blocked.
- Hyponatremia (low ECF sodium).
- Neurotransmitter synthesis is compromised due to Golgi dysfunction in the presynaptic neuron.
