The correct option is A.
Living organisms depend on their environment to survive, when there are changes in the environment which are not favorable to the living organisms, it will eventually leads to the wiping out of the living organisms. As time goes on and the environment recover, the living organisms that will be found in the new environment are those who will be able to survive in it.
The answer is Starch molecules are larger than glucose molecules
The experiment show that the result of starch molecule test show higher concentration of carbohydrate than glucose. This show that the starch is made of multiple sugar. Because the starch is made of multiple sugar, it should be obvious that the size of the starch also bigger of the glucose.
The correct answer is B.
Channels and pumps are transmembrane proteins that create hydrophilic tunnels across the membrane. This allows molecules to be diffused through them. The channels and pumps are highly selective and only allow the diffusion of specific molecules. The channel's structure blocks the contact of the molecule with the head and tail of the phospholipids that form the membrane. As we said, the channels and pumps are proteins, so they are formed by amino acids. Therefore, the molecules passing through channels and pumps, only come in contact with the amino acids.
The non-coding sections of DNA are removed prior to translation in a process called introns.
I think this might be the answer but I will keep looking if it is not.
