Answer:

The answer is d. the continual stretching of giraffe's necks to reach leaves led to longer necks.

Explanation:

This statement was one of the main ideas of Lamarck's proposal inheritance. He thought that as giraffes needed to elongate their necks in order to reach the higher parts of the trees, then, the necks actually elongated. So the need was prior to the mutation. We now know that mutations happen before the change in the whole population.

What are some benefits of enzyme production in the process of digestion.
Rudik [331]

Answer:

<u><em>definition;</em></u>

enzymes are protein that catalyze speed up the biochemical reactions and are not changed during the reaction . the molecules at which enzyme work  are called <em>substrate </em> and enzymes convert them into  different molecules called products.

<em><u>benefits of enzyme in digestion ;</u></em>

enzyme lower the activation energy in several ways. they may alter the shape of substrate and reduce the requirement of activation energy . enzyme may also  lower activation energy by bringing substrate in correct orientation to react . enzyme break down <em>carbohydrates, lipids and  proteins  </em>which are component of human food .In digestion larger molecules are broken into smaller molecules like amino acids ,simple sugars ,fatty acid ,vitamins ,salts and water to provide to cells.  these molecules are  a part of larger molecules like protein ,polysaccharids  and lipids . enzymes like amylaze, lypase   ,salivary amylase, pepsin ; it is a very strong protein digesting enzyme it is released in its inactive form pepsinogen  which is converted into pepsin with the help of H-C-L  hydrochloric acid it takes part in digestion in stomach

Explain the meaning of the symbols as they are used in this expression.
Dmitrij [34]

Answer:

  • A, B, C and D are: elements or molecules
  • A and B are: reactants
  • C and D are:  products

Explanation:

The expression "A + B <--> C + D" represents a chemical equation. A chemical equation represents the "mixture" of molecules or elements that will react and form other molecules and elements, so we can say that A, B, C and D represent molecules or elements.

But not only that. In a chemical equation, the elements and molecules that are before the symbol "<-->" represent the reagents in the equation. Therefore, A and B are the reagents. The elements or molecules found after the symbol "<-->" are the products of the reaction. Therefore, C and D are the products.
