Community ecologists study the factors that determine the abundance of different species. The Abundance of three algae species (

Tema [17]

Answer:

Explanation:

Given that:

The abundance of three algal species in Lake A is now represented by the vectors:

[97, 84, 43] and [100, 80, 50]

Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:

a = [100 -97, 80 - 84. 50 - 43]

a = [3, -4, 7]

Thus, the magnitude of that change is:

$|a| = \sqrt{(3)^2 +(-4)^2+(7)^2}$

$|a| = \sqrt{9+16+49}$

$|a| = \sqrt{74}$

$|a| =8.6 \ mg/mL$

The abundance of three algal species in Lake B is now represented by the vectors:

[25, 59, 22] and [20, 63, 15]

At Lake B, the change occurring in the vector of algae species can be determined as:

b = [20 -23, 63 - 59. 15 - 22]

b = [-3, -4, -7]

Thus, the magnitude of that change is:

$|b| = \sqrt{(-3)^2 +(4)^2+(-7)^2}$

$|b| = \sqrt{9+16+49}$

$|b| = \sqrt{74}$

$|b| =8.6 \ mg/mL$

Hence, for both Lake A and B, the magnitude of change is the same.

This is a volume of space that is empty of matter. Example: Sound cannot travel here.

aleksandr82 [10.1K]

Answer:

Vacuum

Explanation:

A vacuum is usually defined as a space in which there is an absence of matter. It can also be said that there is an extremely low amount of pressure due to which the particles present in it are not affected by any type of process that occurs in space. The value of pressure is lower than the value of normal atmospheric pressure.

For example, sound cannot travel in space because there is no medium such as water and air through which the sound waves can propagate.

When health care teams solve problems, it is important that in the final stage, all team members _____. Have a say in the goals

Nadusha1986 [10]

Answer:

The correct answer is ''understand their roles''

Explanation:

Teamwork in a health team is considered important as a way of dividing responsibilities, correctly attending to the roles in a work team and the functions of the figures that intervene in the teamwork in order to achieve recovery the health of the patient more quickly. Each of the health professionals in this group or team must have a role to fulfill the desired objective; the team is a group of individuals who cooperate to perform a particular routine activity; there is a link of reciprocal dependency that unites the members of the same team with the others. This vision is justified, for each professional to have a different perception of the situation, it is the “union” of the different perceptions that facilitates the understanding of the whole, allowing a glimpse of the patient as a whole. Usually, the general doctor assumes the role of knowing the patient in depth, in order to be able to guide on health problems and decide together with him or her the treatments and objectives to be achieved.
