Which of the following is NOT a reactant of photosynthesis?
Irina-Kira [14]

Photosynthesis produces both glucose (sugar) and oxygen as products in the chemical reaction. Plants use photosynthesis to take in sunlight, water, and carbon dioxide as reactants and produce glucose for energy and oxygen. The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll , while the products are glucose (sugar), oxygen and water.

I hope this helps =)

3. Algae makes energy-rich carbon compounds through
Thepotemich [5.8K]

A complementary process in nature either adds (options 3, 6, and 7) or removes ( options 4 and 5) carbon dioxide from the atmosphere.

<h3>Complementary processes and it's benefits</h3>

The processes that leads to the addition of carbondioxide back to the atmosphere include the following:

  • The eruption of volcanoes.

  • Cellular respiration carried out by organisms to release energy from food molecules.

  • The use of gasoline to power cars

The processes that leads to the removal of carbondioxide from the atmosphere include:

  • The production of energy-rich carbon compounds through photosynthesis.

  • The dissolution of carbondioxide in rainwater.

You water three sunflower plants with salt water. Each plant receives a different concentration of salt solutions. A fourth plan
Kruka [31]

Answer:

The fourth plant that receives pure water is the control group.

Explanation:

The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, in this case, <em>the different concentrations of salty water that each plant receives</em>. The control group provides a reference point. It must be selected from the same population of the treatment groups. Both groups must be similar in every variable that might influence the results, <u>except for the study treatment.</u>

A student does an experiment for a science fair to study whether temperature affects the timing of a cricket’s chirps. The stu
nexus9112 [7]

The frequency of chirps increases as the temperature increases. The correct option is B. <em>The chirps occur closer together as the temperature increases.  </em>

-------------------------------

<h2><u>Available data:</u></h2>

<h3>Data recorded by the student </h3>

<em><u>Day      Temperature   Average time between chirps (sec)</u></em>

1            21                             2. 5

2           22                            2. 6

3           23                            2. 2

4           24                            2. 3

5           25                            2. 0

6           26                             1. 8

7           27                              1. 9

8           28                             1. 8

9          29                             1. 4

10          30                             1. 2

11           31                              1. 5

<u>12          32                             1. 1</u>

In this experiment the student recorded the time in seconds <u>between </u><u>chirps</u>.

We can see that <em>as the </em><em>temperature increases</em><em>, in general, the</em><em> time</em><em> between</em><em> chirps decreases</em>.

  • At 21ºC the time between chirps is 2.5 seconds
  • At 26ºC the time between chirps is 1.8 seconds
  • At 32ºC the time between chirps is 1.1 seconds

According to this information, if the average time between chirps decreases with the temperature increase, we can assume that<em> the </em><em>frequency</em><em> of chirps </em><em>increases</em><em> as the temperature gets higher. </em>

<h3>Options,</h3>

<em>A) The higher the temperature, the fewer chirps there will be in 10 seconds</em>.

Wrong. The number of chirps in 10 seconds will depend, not only on the frequency but also on how long the chirps last. Since the student did not record the time of chirps, we can not make this conclusion.  

<em>B) The chirps occur closer together as the temperature increases</em>.

True. The chirps increase in frequency as the temperature increases, so they occur closer together.

<em>C) The chirps become farther apart as the temperature increases</em>.

Wrong. We can see how the time between chirps decreases as temperature increases, meaning that they are closer not farther.

D) There is no relationship between temperature and the time between chirps.

Wrong. If we make a graph we will see the tendency and the relationship between chirps and temperature.

Graphs usually explain the relationship between variables. In this example, the relationship would be inverse.
