Answer:
<em>Competition without division of resources may lead to extinction.</em>
Explanation:
Some species are better adapted to live in an environment as compared to other species. If resources become scarce then the species with better traits might take up all the resources of a species which are not better adapted. This will cause the species with unfavourable traits to become extinct. To survive in an environment, an organism needs to change and adapt according to the conditions of the environment. Otherwise, the species will become extinct.
The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
This relates to the definition of the word because asthma is a condition which causes difficulty in breathing.
