Answer:
The correct answer is A) There are more species that have the ability to travel 5 kilometers than can travel 15 kilometers.
Explanation:
The ecologists MacArthur and Wilson took the term island biogeography theory to refer to the predictions about the number of species that could be inhabiting on an island.
Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are <u>the distance from the mainland and the size of the island. </u>
At the same time, these factors affect inmigration and extinction rates. According to the theory, the inmigration rate depends on the distance between the island and the mainland, of the number of species that keep living on the mainland and not stablishing on the island and the <u><em>probabilities that the species can move from the continent to the island</em></u>. Islands that are closer to the continent have higher possibilities of receiving immigrants than those islands that are located farther from the mainland. This is the effect of distance.
The extinction rate depends on the area of the island, the number of species living on it and the extinction probability of these species. The effect of size is reflected in the relation between island size and species diversity. In smaller islands, the probability of extinction is higher than in bigger islands. Bigger islands can have more species than smaller ones.
In the case of two islands of the same size and different distance to the mainland, both of them will have the same extinction rate, but the one closer to the continent will have a higher immigration rate, and so, a higher amount of species. The S value will be higher on the island closer to the continent.

Answer:
The correct answer is option D: "Strategic".
Explanation:
Strategic planning refers to a series of steps that an organization needs to follow in order to achieve the goals of the institution, in this case, a hospital or the orthopedic unit. Strategic planning is usually performed by the directors of the institution, therefore, this type of planning will be the least useful during the first shift to treat the 75-year-old client. Other types of planning focused directly on the client are more useful than strategic planning at this point of the treatment.
Water is a unique molecule which contains inter-molecular forces like vandar wall's forces and hydrogen bonding that results in extremely strong bonding forces among water molecules.
Cohesion and adhesion are the properties of water which refer to the fact that water molecules are not only very strongly attracted to water molecules but also to other polar molecules of any type.
This is the cohesive nature of the water which makes water a water drop and it is the adhesive nature of water due to which water takes the shape and available space in a glass or jar of water .
How these properties are a result of bonding between atoms?
Cohesive properties:
- We are well aware of the fact that water is composed of one atom of oxygen and two atoms of Hydrogen.
- The two hydrogen atoms align themselves in such a way that oxygen is in middle of them. Due to great electronegativity difference Oxygen gets a partial negative charge while Hydrogen atoms get partial positive charges.
- Now one oxygen atom of one one water molecule attracts the partial positive charged hydrogen atom of another water molecule, and this attraction causes the bonding. This type of inter-molecular forces of atom gives water cohesive properties.
Adhesive properties:
- If we talk about adhesive properties through which water is attracted to other materials of polar nature, these adhesive properties are also due to same nature of bonding.
- Any polar compounds can easily get bonded with water due to polar nature of water molecules. You can see the attached figure for better understanding of bonding properties of water.

When the word Storms is used in relation to climatic
controls, we are not talking about tornadoes, hurricanes and the
like. Rather this control deals with the presence of moisture in
the atmosphere, the various means by which moisture is removed
from the atmosphere and the forms the moisture takes.
Meteorologists are very interested in the amount of moisture in
the air not only because the presence of water vapor is an
indicator of the potential for precipitation, but the energy
released as water vapor changes states provides the energy for
storms.
Moisture, or humidity, is a general term we will use to
describe the amount of water vapor in the air. There are a number
of ways to express the amount of humidity in the air -- the most
common being absolute humidity, relative humidity and mixing
ratio. We will take up each of these shortly.
