An antimicrobial<span> is an agent that kills microorganisms or inhibits their growth. </span>Antimicrobial <span>medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria and antifungals are used against fungi.
</span>
Selective toxicity<span> refers to the ability of the drug to targets sites that are relative specific to the microorganism responsible for infection. Sometimes these sites are unique to the microorganism or simply more essential to survival of the microorganism than to the host.

Selective theory relates to antimicrobial because the antimicrobial is the drug that kills microorganisms and inhibits there growth,  selective theory is the ability of the drug.

Identical

Inconsistent

Non-testable

The Answer is Identical

Explanation:

The groups of scientists in different parts of the world who are dating fossils found in a rock layer of the same geologic time period. The findings have to have some common characteristics which links it to being in the same geologic time period.

This however validates the fossils having to be identical to match those found in other parts of the world.

Which of the following is the term used to describe a body resistance to change in motion
bija089 [108]
<span>Inertia refers to a body or any physical object’s resistance to a change in motion. This change in motion includes, speed, direction, or state of rest. Objects that have moved will keep moving in a straight line at constant velocity. Inertia is one of the fundamental principles of classical physics, for it describes motions of objects and how they are affected when forces are applied on them. Inertia is one of Isaac Newton laws from Philosophia Naturalis Principia Mathematica. </span>

Form a hypothesis about the relationship between vegetable mass and salinity of the solution
mihalych1998 [28]

Answer:

HYPOTHESIS: IF the salinity of the solution decreases, THEN the vegetable mass increases.

Explanation:

Hypothesis, in an experiment, is a testable explanation or prediction made to solve an observed problem or answer a question. It shows how one variable called independent variable affects another variable called dependent variable. It is usually written in the "IF, THEN" format.

In this case, the question states that there is a relationship between vegetable mass and salinity of the solution. This means that the question has been asked that "Why is the vegetable's mass affected by salinity of a solution". Hence, a hypothesis can read:

IF the salinity of the solution decreases, THEN the vegetable mass increases.

!!!almost done!!!
Vitek1552 [10]

Answer:

1.

Explanation:

Xylem cell is a plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

2. Phloem is the vascular tissue in charge of the transport and distribution of organic nutrients. The phloem is also a pathway to signaling molecules and has a structural function in the plant body.

3. Stomata are composed of a pair of specialized epidermal cells referred to as guard cells. Stomata regulate gas exchange between the plant and environment and control water loss by changing the size of the stomatal pore.

4. Guard cells optimize leaf gas exchange in response to changing environmental conditions and their turgor is controlled by alterations in atmospheric CO2 concentration, light intensity, humidity, and the drought hormone abscisic acid.
