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.

In general, field of study refers to gaining the knowledge in a particular branch. On the other hand, science means the system where we can attain the knowledge about the universe. This always delivers with theoretical and experimental descriptions in a detailed manner about natural phenomenon.
This handles with each and every aspects about living organisms and environment. This paves the way to know more details in particular part. Hence, field of study like physics, engineering also referred a science in this manner.
Alleles on homologous chromosomes determine traits.
A Excess salt deposited in the soil when irrigation water evaporates is correct (apex)
The correct answer is - predator species in a community.
In the terrestrial ecosystems, a very good and usually sure predictor of the biodiversity is the existence of a predator species. The more predator species there are, the higher the biodiversity, and vice versa, the less predator species, the lesser the biodiversity.
The reason why the predators are such a good predictor of the biodiversity is that they are the species that are on the top of the food chain. That means that the predators are dependent for their survival on all the other species bellow them in the food chain, which is pretty much all species apart from themselves.
If a predator is present, than there has to be pray. If there's pray, omnivores and herbivores, than there has to be plants. All of the organisms are connected to one another, and the ones on the top of the food chain are the most dependent on the others, thus their existence usually means a healthy ecosystem with higher biodiversity.
