Why would you learn less about an organism if it is were isolated from its surroundings than if you were able to observe the sam

Dahasolnce [82]

Answer:

this one`s been up for debate for awhile now.

1. it depends on the organism

learning about an organism could be considered 'easier' to study in different ways. for example, if you are studying marine life, you will most likely have to keep it in a water habitat to watch it alive. If you are studying a land species, then watching from it`s natural habitat will give you more accurate results. sometimes the environment can affect an organisms internal systems more than you may think. this leads into my second point.

2. it depends on what you are trying to study

if you are trying to learn about the mating process, seasonal activity, migration, or external behavior, then monitoring it from it`s natural habitat or an area that is a close copy is your best option. but if you are looking into studying internal organs/systems or cells, then in most cases, the organism will need to be taken out of its natural habitat. only in very careful situations is it left in a habitat during examination.

How do mutations lead to genetic diversity?

inn [45]

The mutation Mutations are changes to an organism's DNA and are an important driver of diversity in populations. This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

Sort the items based on whether they have gravitational potential energy or chemical potential energy. liquid petroleum gasoline

poizon [28]

Explanation:

Gravitational potential energy is the energy of body due to its position in the gravitational field.

Whereas chemical potential energy is the energy within the chemical bonds of a substance.

For example, when we eat an apple then we get energy in our body so, it is the chemical potential energy stored in the apple.

Items sorted on the bases of gravitational potential energy and chemical potential energy are as follows.

Gravitational potential energy:

a ball thrown up in the air.

a stone rolling downhill.

water stored in an overhead tank.

Chemical potential energy:

liquid petroleum gasoline used in cars.

apples that people eat.

firecrackers that people set off.
