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 />
<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>

Nutrient loss is the reduction or elimination of the nutrients in food. Nutrients are very important in the development of cells in the body and also giving energy and vitality to the bones.
Please note that your question is incomplete, so i am giving you a general overview.
Some of the factors that leads to nutrient loss in food includes:
- Overcooking (exposure to high level of heat)
- Freezing
- Drying, etc.
Therefore, to minimise nutrient loss, it is vital that food is well preserved and is finished immediately, to reduce or totally eliminate the need to freeze, overcook or reheat food.

Would cause a dysfunction in the mitosis process of the cell, either the cell will redo its process of division.
<span>The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size. </span>
Answer: Annelida
Leeches are soft bodied segmented parasitic worms. They belong to the phylum Annelida. They are hermaphrodites which means they exhibit sex organs of both male and female.
The characteristics which are found in leeches which group them into Annelida are:
1. The body of the leeches are bilaterally symmetrical like other Annelids. The body organs are also segmented.
2. They have a closed circulatory system in which the heart pumps the blood to all the parts of the body.
3. Leeches either exhibit a protusible pharynx or proboscis which allows them to suck the blood of the host such features are also common in other Annelids.
Your correct answer would be yes because the transcript is constantly increasing
