Answer:

Traits acquired during an organism's lifetime cannot be passed

Explanation:

<em>The law of use and disuse of organs as postulated by Jean Lamarck was wrong due to the fact that environmentally acquired characters cannot be passed to offspring.</em>

Changes to organisms that are not the level of the gene cannot be passed to the offspring. <u>For example, a wrestler that got big muscles due to constant work out cannot pass big muscles to his offspring. The offspring will need to work out in order to have big muscles. This is because big muscles in the wrestler is environmentally acquired.</u>

Only changes that happen to the genome of an organism (mutation) can be passed to offspring.

Which statement best describes how a catalyst can speed up a chemical reaction? A) The catalyst makes lower energy pathways avai
melamori03 [73]

Answer:

A) The catalyst makes lower energy pathways available.

Explanation:

A catalyst is a substance which speeds up a chemical reaction without itself being used in the reaction. Activation energy is the thresh hold energy which is required to initiate a chemical reaction. In the absence of catalyst, the activation energy is high therefore reactions are slower. But, presence of catalyst lowers the activation energy required to initiate the reaction as a result of which the reaction gets an alternate energy pathway to proceed which is responsible for speeding up the reaction.
