Answer:
C.
Explanation:
You need more data and facts. The reason why the sky is mostly blue and not any other color is because the color blue travels in small and shorter waves. The light from the sun gives off all the colors of the rainbow but we only see white. All the light travels in a straight pattern unless something gets in the way of it. It's either it reflects, bends, or is scattered.
It’s a nerve cell. A neuron/nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses. It is the main component of nervous tissue in all animals except sponges and placozoa. It had a nucleus that contains genes and contain cytoplasm, mitochondria and other organelles.
Answer:
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.
RNA is most commonly if not almost exclusively found in thr cytoplasm of the cell.
