Substances that enter the cell without the expense of cellular ATP, but are too large to directly pass through the membrane, use cesicles in order to gain access to the inside of the cell.
Answer;
Electron transport chain.
Explanation;
-Cellular respiration involves three different phases, namely; glycolysis, krebs cycle, and electron transport chain.
-Electron transport chain is the phase during which water is produced during cellular respiration. During electron transport chain electron carriers from glycolysis and citric acid cycle donate electrons and protons to the electron carrier proteins of the electron transport chain. Together with oxygen, electrons and protons form molecules of water. The products of the ETC is ATP , then water and carbon dioxide as byproducts.
Answer:
Familial Alzheimer's disease os the type of inherited dementia.
Usually dementias do not pass on to the generations but some do.
Explanation:
If a parent has a mutated gene that causes this inherited disorder , each child has a 50% chance of inheriting it. The presence of the gene means that the person will eventually develop Alzheimer's disease, usually in their 40s or 50s.
Alzheimer's disease is an irreversible, progressive brain disorder in which brain cell death occurs. It is a neurodegenerative disease, that slowly destroys memory and thinking skills and, eventually, henders doing the simplest tasks.
In Alzheimer's, the tissue has fewer and fewer nerve cells and connections. It usually occurs in late 50s or mid 60s.
<span>Cnidarians are most closely related to </span>platyhelminths. Hopes this helps.
<span>The three points of the cell theory state that:
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure, function, and organization in all organisms.
3. All cells come from pre-existing, living cells.
</span>While all of there are true regarding cells, "Every cell have a nucleus that contains genetic material" <span>is not actually part of the cell theory. The answer to your question is D.
I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.</span>
