amino acids is the answer in apex
Answer: The hypothesis can be completed as-
If the type of food available changes, then the frequency of beak also changes.
Explanation-
Natural selection is a theory of evolution that was given by Charle's Darwin. According to this theory, organisms that are capable of adapting themselves ( that is having beneficial traits, which enhance their survival) in the changing environmental conditions survive and increase their number by means of reproduction.
According to the information given in this question, the type of food available is changing, which will result in the change in the frequency of bird beaks inhabiting that area. This would indicate their adaptation so as to survive under the changed food type, otherwise they will be unable to consume the food resources and will die out.
I think that both the dialysis tubing and the small intestine are selectively permeable. Which means they allow only some and not all materials to pass through; for example; glucose which is a simple molecular sugar; will pass through, however larger molecules such as starch can not pass through. A dialysis tube is a semipermeable membrane that allows molecules of certain size to get in or out, while keeping molecules above that size in. They are often used to remove impurities from preparations of proteins or other macromolecules and also to normalize pH of a preparation.
Answer:
D ) Telophase
Explanation:
During anaphase, the sister chromatids are separated and pulled to opposite ends of the cell. During telophase, the nuclear envelope begins to re-form around the divided chromatids.
The correct answer is A. The oxygen molecule accepts electrons from a compound called cytochrome a3. Cytochromes contain a central Iron atom that can either be in the oxidised state(ferric state) Fe3+ or reduced state(ferris state) Fe2+. The cytochrome is oxidized by giving the electron to O2(O2 is reduced).O2 becomes 2O- that quickly react with H+ to form H2O.
