When placed into an hypertonic solution, animal cells will shrivel up, while plant cells will stay firm thanks to their air-filled vacuole. In a hypotonic solution, the cells will take on water and appear more plump. In an isotonic solution, they'll stay the same.
Answer: No
Explanation: Since when a child is born it has DNA from both. As an example, the mom has brown hair, father has blonde hair, the child would take the DNA for the type of hair they get, either blonde or brown. So since its blood, the fathers is A, and the boy's is B, therefore it didn't take any of their DNA's so nope, he isn't the father.
Answer:
Three proteins directly contribute to the proton gradient by moving protons across the membrane
Explanation:
The Electron transport chain is a group of proteins and molecules incrusted in the internal mitochondrial membrane and organized into four complexes, I, II, III, and IV. These complexes contain the electron transporters and the enzymes necessary to catalyze the electron transference from one complex to the other. Complex I contains the flavine mononucleotide -FMN- that receives electrons from the NADH. The coenzyme Q, located in the lipidic interior of the membrane, conducts electrons from complex I and II to complex III. The complex III contains cytochrome b, from where electrons go to cytochrome c, which is a peripheric membrane protein. Electrons travel from cytochrome c to cytochromes a and a3, located in the complex IV. Finally, they go back to the matrix, where they combine to H+ ions and oxygen, to form the water molecule. As electrons are transported through the chain, protons are bombed through three proteinic complexes from the matrix to the intermembrane space. These are complexes I, III and IV.
Answer:
a) the molecules can be found in the picture below
b) (i) isocitrate lyase ( isocitrate to glyoxylate)
(ii) malate synthase (glyoxylate to malate)
c) Glyoxylate cycle do no exist in animals
Explanation:
b) in the glyoxylate cycle isocitrate lyase helps in conversion of isocitrate to glyoxylate. Also, helps in conversion of glyoxylate to malate by using malate synthase.
c) Glyoxylate cycle do no exist in animals, it only exist in plants and bacteria. This is because they can produce glucose from acetyl-CoA in required amounts.They have the ability to change acetyl-CoA from fat into glucose. But in animals, this mechanism is not possible.
Every species exhibits variations based on various genes being activated at various times. An example with humans can be eye color or hair color. What species means is that all members of a species can procreate with healthy, capable of procreating progeny, but anything else is just a variation.
