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.
Answer:
Low Enzyme Production is the reason for no breaking down of food.
Explanation:
If the digestion of food did not occur so it means that there is low enzyme production because enzymes are responsible for the breaking down of food substances into simpler ones in order to absorb by the cells for the generation of energy in the form of ATP. So we can conclude that low enzyme production is the only reason for the stopping of breaking down or digestion of food.
The DNA, mRNA and tRNA are the essential nucleic acids that initiate protein synthesis. The DNA contains the genetic code of our human body in the form of chromosomes. It is composed of nucleic acids like uracil (U), guanine (G), adenine (A) and cytosine (C). The messenger RNA or mRNA carries this code called codons expressed in three-letter codes. Each amino acid has its own assignment of code. The mRNA carries this code to the ribosome which is the site for protein synthesis. The translational RNA or tRNA contains anti-codons to translate the codes in the mRNA into amino acids that link together to form proteins.
