Answer:
Pollen grains land on the stigma and move down the pollen tube into the ovary.
The first question can be answered by science due to its logical features.
<h3>Why is land use more important than water use?</h3>
The above question is answered through science because this is a logical question and we know that science answers questions logically and experimentation.
So we can conclude that the first question can be answered by science.

Answer:
This is for the table at the top
<em>Plentiful roaming space</em>- increase - <u>because they</u><u> have more space they can live in.</u>
<em>Severe</em><em> </em><em>drought</em><em> </em><em>-</em><em> </em>decrease<em>-</em><em> </em><em> </em><u>because they</u><u> </u><u>wont</u><u> </u><u>have</u><u> </u><u>enough</u><u> </u><u>water</u><u> </u>
<em>abundant food </em><em>source</em><em> </em><em>-</em><em> </em>increase - <u>Because they have enough food to sustain themselves </u>
<em>Habitat </em><em>destruction</em><em> </em><em>-</em><em> </em>decrease - <u>Because they won't have a place to live in </u>
<em>Elimination of predators</em><em> </em><em>-</em><em> </em>increase - <u>Because there will be less animals hunting them for food.</u>
<em>Lack of competition</em><em> </em><em>-</em><em> </em>increase - <u>Because they won't have to compete for food which will allow them to have more.</u>
<em>Disease</em><em> </em><em>outbreak</em> - decrease - <u>Because the disease will kill a lot of them and can potentially cause birth rates to go down</u>
Scientists most often produce new genetic variations of organisms by causing mutations with radiation or chemicals and then selectively breeding in order to emphasize the desired traits in the new variations. The Dachshund is an example of this. By breeding two dogs with a similar mutation that caused student legs and elongated backs breeders were able to create a new variation not found in nature.
