Cholera develops when the bacterial toxin prevents G-protein inactivation , which leads to the continuous production of cAMP.
Answer:
False
Explanation:
Prokaryotes do not have a nucleus.
This means their DNA is not enclosed in a nucleus and instead is in the cytoplasm.
On the other hand, eukaryotes have nuclei, so their DNA is enclosed within a nucleus.
So, this statement is false.
Prokaryotic cells are cells that have no nucleus, and are either cells of bacteria or protists. Eukaryotic cells are cells that do have a nucleus, and may have other organelles that prokaryotic cells don't have, like a vacuole or lysosome, etc. Hope this helps!
Blood is the fuel that keeps you going! Oxygenated blood is brought to organs and tissues via the arteries, while veins bring deoxygenated blood back to the heart to be replenished. The point is, without the respiratory system your blood would be useless.
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
A more complex interconnected system of food chains is a consumer-resource system.
