Answer:
<h3>Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.</h3><h3>.<u>Equation</u></h3>

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
The independent variable influences and causes a change in the dependent variable. <em>Hunting </em>-independent variable- influences on the species <em>population sizes</em> -dependent variable-.
---------------------------------------------
<u>Available data:</u>
- Question: Are endangered birds populations increasing by being
protected from hunters?
- Methodology: Counting the number of Whooping Crane, California
Condor, and Black Swans every ten years.
Before conducting the experiment, researchers need to identify the study groups –experimental and control groups- and the variables involved.

<em>⇒ The</em><em> study groups</em><em> are the</em><em> species</em><em> Whooping Crane, California Condor, and Black Swans.</em>
⇒ Variables
- Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is modified to analyze its effects on another variable. The researcher changes on purpose the independent variable to observe the response of the dependent variable.
<em>In the exposed example, the independent variable is </em><u><em>hunting</em></u><em>. Hunting </em><em>affects </em><em>the previously mentioned </em><em>species</em><em>, moreover because they already are endangered species. So </em><em>excessive hunting</em><em> might cause species </em><em>extinction</em><em>. Reduced or </em><em>controlled hunting</em><em> might help the</em><em> population sizes </em><em>to remain</em><em> constant.</em><em> But </em><em>no hunting </em><em>at all might be closely related to an </em><em>increase</em><em> in their </em><em>population sizes</em><em>.</em>
- Dependent variable: Refers to the variable, which response depends on any change in the independent variable. Any change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable.
<em>In the exposed example, the species </em><em>population sizes</em><em> are the </em><em>dependent variables</em><em>. Researchers measure every ten years how many animals of each species remain in the study area. These numbers </em><em>depend</em><em> on </em><em>hunting</em><em>, and their changes are </em><em>inversely proportional</em><em> to the change in </em><em>hunting</em><em>. An increase in hunting means a decrease in the species population size. a Decrease in hunting means an increase in the species population sizes. </em>

Nitrites are 307880 115 and control is 30 8112 1250
Let X be nitrate group and let Y be a control group.
If ∪X-∪Y∠0 then we can say that nitrates decrease the number of amino acids which is taken.
Hypothesis test.
H0:∪X-∪Y=0Vs. Where H1:∪X-∪Y∠0.
Sample for X = 7880 and Y = 8112 and Sx∧2=variance sample for X = 1115∧2 = 1243225 and Sy∧2 = variancesample for Y= 1250∧2 = 1562500. The size of the sample = 30 for both cases.
Test statistics is Z =((7880-8112)-0)/squareroot (1243225/30+1562500/30) = 0.758623)
Value of P = P(Z∠z)
=P(Z∠-0.758623).
Since P-value is greater than the importance of 0.02, we can not reject the null hypothesis. The conclusion is that ∪x-∪y =0 a good example is nitrates does not decrease the number of amino acid which is taken.

Answer: Stage M (Mitosis).
Explanation: The root tip is a meristem and this means that the root tip is responsible for the root growth. To do that, root tip cells divides actively to form root tissues, so that if we look an onion root tip under the microscope, the majority of cells will be in division, called mitosis, or Stage M of the cell cycle.
