Explanation:
<u><em>Intercellular communication involves an electrical charge moving along a cell membrane.</em></u>
Answer: Option D
<u>Explanation:</u>
Intracellular communication means movement between two cells. The Intercellular communication means movement of molecules within a cell. All these cells are interconnected through gap junction. Gap junctions connect directly to the cytoplasm of the two cells.The communication happens through the chemical synapse.
Intercellular communication is required for the proper growth of the cells. Intracellular communication happens by signals passed on through the cell membrane to the nucleus. It is important to control the cells activities.
The medulla oblongata is the part of the brain stem that regulates the bodily processes that are automatically regulated such as respiration and blood pressure. During respiration process, the medulla oblongata functions by detecting the level of carbon dioxide and oxygen in the blood stream and sending necessary signals in form of nerve impulses to the heart muscles and diaphragm for necessary actions. This shows that the respiratory system and the circulatory system work together and that is the reason why heart rate and breathing rate are both controlled by medulla oblongata.
Answer:
true
Explanation:
The value of gene frequency always exists between 0 and 1.
For example, if all of the alleles in the pea plant population were tall alleles (represented as “T”) and none of the alleles were dwarf alleles (represented as “t”), then the “T” allele frequency would be 100% or 1, and “t” allele frequency would be 0% or 0.
