Answer:
The correct answer is A and D
Explanation:
According to Russell's conception that lies in natural proton gradients. He states that Four billion years ago, alkaline fluids bubbled to produce mildly acidic oceans (As CO2 levels were about a thousand times higher, and it reacts with H2O to form carbonic acid, rendering the oceans mildly acidic). Acidity is just a measure of proton concentration, higher in the oceans than in vent fluids. This difference has given rise to a natural proton gradient across the vent membranes that had the same polarity (outside positive) which is similar to the electrochemical potential as modern cells have. This might be the reason that last universal common ancestors of all the three domains have evolved proton pumps.
Answer:
Cooked Broccoli
Cooked Kale
Explanation:
Including Broccoli, all the vegetable of cruciferous family have cancer fighting properites. Specially for this purpose Broccoli is preferred because it has adequate amount of sulforaphane which is a potent compound that boosts the body's enzyme system and as a result of this the cancer causing chemicals can be flushed down easily by the body. Sulforphane also targets the cancer stem cells. These are the cells that promote the tumor growth.
The body temperature of the mammal will be higher than that of the reptile. this is because the mammal body temperature does not depend on its environmental temperature while a reptile does not have a stable body temperature and depend on the temperature of its environment.
In the event of an acid spill, a base can be poured onto the acid to neutralize the acid to allow a safer cleanup.
