Answer:
The correct answer is iron-transport proteins
Explanation:
Siderophores are proteins produced by bacteria, and compete with the host's iron-transport proteins. They aim to bind and "hijack" the host's cell iron molecules for their own pathogenic cell processes
Cells require a structure that regulates the transfer of material in and out of the cell. This structure is the –
Cell membrane.
Answer:
B) bacteria
Explanation:
Bacteria helps dead organisms decompose and enrich the soil with nutrients, the nutrients then get reabsorbed by producers/plants and the cycle begins again.
Answer:
<em>decreases blood flow</em>.
Explanation:
I'll assume the question is about one of the effect of blood flow resistance.
Resistance forces are those forces that opposes the flow of blood through the blood vessels. Resistance forces in the blood vessels changes with the diameter of the blood vessels, and always acts against pressure to move the blood against the blood vessels. If the resistance forces in the blood becomes equal or greater than the blood pressure, there will be no blood flow through the blood vessels. So generally, resistance forces in the blood vessels acts to decrease blood flow through the blood vessels.
