Water is drawn upward from the roots through plant tissue to the leaves by ________.
Assoli18 [71]

Answer: a. capillary action.

Water is a taken up by the plants from the roots, which needs to be transferred to all the parts of the plants to conduct cellular metabolic processes like photosynthesis and respiration. The properties of water molecules are responsible for conduction of water from the root to the stem and other higher parts. The cohesion is the property of water which water molecules are combined with each other due to sharing of bonds at the atomic level. The adhesion is the property of water which allows water molecules to attach with other substances or substrate.  Adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. Capillary action occurs when the adhesive force is greater than the cohesive force between water molecules. The supply will be upward and force of gravity will also be applicable on this. Capillary action mimics the transfer of water from a tube or pipe. In this way water is drawn upward from the roots through plant tissues to the leaves by capillary action.

Antelopes and elephants feed on the same species of grasses and shrubs in a savanna and the fitness of each species is reduced w
34kurt

Interspecific competition occurs between antelopes and elephants.

The term "competition" refers to the process that takes place among many species as they fight for the same limited resources in order to maintain their own existence. This struggle over resources occurs among organisms because these species occupy niches that overlap, and as a result, they are compelled to use the same resources like food, water, and shelter.

Competition can be either interspecific or intraspecific. The term "interspecific competition" refers to a type of competition that occurs between various species that live in the same biological area and are dependent on the same source of food.

In the question, both antelopes and elephants feed on the same grass and shrub species. Therefore they compete amongst themselves as a result of which their fitness is reduced.

Mr. Malone is going into a shock because of blood loss, so paramedics infuse a saline solution. Why would this help?
fredd [130]
Saline solutions have the same or close to the same amount of salt as our blood does, so we get the amount of salt needed for our bodies. During blood loss, you lose the salt you need, so they're basically adding it back in with the saline solution, making your electrolyte balance go back to normal level. It also gives us the right amount of water to keep us hydrated.
