Answer: A
Explanation: Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products. This table shows examples of substances required by cell and associated waste products.
Answer:
Uno se pierde, el otro se recicla.
Explicación:
El movimiento de nutrientes difiere del flujo de energía en un ecosistema porque los nutrientes se pueden reciclar mientras que, por otro lado, la energía se pierde en el ecosistema. Tanto los nutrientes como la energía fluyen en la misma dirección y toda la energía del ecosistema proviene del sol, que es la principal fuente de energía. Entonces podemos decir que la energía perdida y los nutrientes se reciclan en el ecosistema.
Answer:
Cytokinesis
Explanation:
Cytokinesis is similar to telophase. The cell devides it cytoplasm into two pieces which creates two daughter cells.
Answer:
The correct answer is - C) pH paper + Phenol red.
Explanation:
Iodine is a reagent and indicator that is used to test confirm the presence of the starch in the sample by producing its characteristic blue-black color.
pH paper is an indicator that helps in telling about the pH level of a specific sample or solution by changing its color.
Biuret reagent is used to test for the presence of protein as it identifies peptide bonds in a solution.
Benedict's solution is an indicator that is used to confirm the presence of simple sugar in the solution or sample.
Phenol red solution is used as a pH scale to identifies the pH value of a sample or solution.
Sudan Iv is used to find the lipids and fats in the sample or solution.
Thus, the correct answer is - C) pH paper + Phenol red test for similar conditions.
No because many genes have to work together to make make something change.
