Which of these scientists is best known for his idea that characteristics an individual gains in its lifetime could be passed on
Anna [14]
This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.

Which of the following information could be included in the description of a grasshopper’s niche, but not in a description of it
Ivan

The niche of grasshopper would include the plant species it eats.

Explanation:

The niche of an organism is different to that of a habitat. A niche includes the interaction between organisms and the food that they eat, whereas, a habitat is a place where organisms are provided with food, protection and shelter.

Habitat is a place of ecosystem that involves other environmental factors like- rain, sunlight, humidity etc. So, food type eaten by grasshopper would be the description of a niche and not a habitat.
