Can the environment and the heritage be used to describe evolution?

1 answer:

7 0

Evolution is caused by genetic mutations that become favorable for survival.

For example if a bird has a mutation that gives it a longer beak and it lives in an environment in which a longer beak lets the bird catch more food- the longer beak becomes a favorable trait.

Now the bird is able to survive “better” thus it lives longer(due to its ability to catch more food). Because of this it reproduces more and passes the trait on to its offspring.
Overtime this mutation takes over the population of birds in the area.

Doss [256]

Answer:

C. Narcotic overdose

Explanation:

The narcotics cause respiratory depression as they decrease the response to the increased partial pressure of carbondioxide pCO2 , thus resulting in depression of the respiratory centre in brain and no hyperventilation occurs Hence option B is the right answer.

Hyperventilation is occurring in option A because aspirin overdose cause direct respiratory center stimulation resulting in respiratory alkalosis causing hyperventilation.

Hyperventilation is occuring in option C as most of the respiratory infections e.g pneumonia is associated with hyperventilation due to swelling and accumuation of fluid in lungs causing fast breath.

Hyperventilation also occurs in high blood glucose levels hence option D is also excluded.

bixtya [17]

Answer:

The cell

Explanation:

The smallest or most specific level of organization that all living organisms (including myself and my neighbors) have in common is the cell.

This is in accordance with the cell theory which has three basic components, including:

1. The cell is the basic unit of life

2. All living organisms are made up cells

3. Cells arose from pre-exsiting cells.

Other levels of organisation include tissues which are group of cells specialized for a certain function, organs which are group of tissues serving similar function, and systems which are group of organs working together as a unit.
