Arisa [49]

Answer:

The correct answer is - (B) As with any living thing, a plant has an optimal temperature range at which it grows and performs best.

Explanation:

Like any other or most of the living organism, plants also required an optimal temperature range as they also required appropriate temperature for their growth and development and perform their functions at their best.

Optimum temperature range is a temperature range at which something performs its best similarly plants perform their cellular functions like photosynthesis, metabolism, reproduction, and many other functions that require a particular temperature range.

________ allow materials to be exchanged between the blood and tissues, ________ carry blood towards the heart, and ________ car
Anuta_ua [19.1K]

Answer:

b.  Capillaries; veins; arteries

Explanation:

Capillaries are the blood vessels with very thin walls. They serve as a site for an exchange of substances such as respiratory gases, nutrients, and toxins between the blood and the cells of the tissues. Veins are the blood vessels that mostly pick the deoxygenated blood from the body cells and deliver it to the heart for oxygenation. On the other hand, arteries are the blood vessels that mostly carry the oxygen-rich blood. They pick the oxygenated blood from the heart and deliver it to body cells. Therefore, veins carry blood towards the heart while arteries carry it away from the heart.

You want to test whether duration of light exposure affects fish reproduction. What would be your control group and experimental
Triss [41]

Answer and Explanation:

During an experiment, data from an experimental group are compared with the data of a control group. These two sets are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals. This variable keeps constant in the control group.

The experimental group is the one that receives the experimental procedure, with changes in the independent variable.  There can be several experimental groups.

In the control group, the variable measured keeps constant, not influencing the results. This isolates the effect of the independent variable on the experiment and helps to find alternative explanations to the different results.

In the exposed example:

  • Control group: Certain amounts of fishes exposed to a normal number of light hours per day. For example, if under natural conditions in its original environment the species is exposed to 12 hour light, then the control group should be exposed constantly to 12 hours light a day to maintain its normal reproductive levels.
  • Experimental group: Certain amounts of fishes, equal to the control group, exposed to a different number of light hours per day. For example, there might be 5 experimental groups: one of them exposed to 4 hours light, a second group exposed to 8 hours light, the third group exposed to 12 hours light (The same as the control group), the fourth group exposed to 16 hours light, and the fifth group exposed to 20 hours light.

Except for light, the rest of the variables should be the same for all the groups.
