The independent variable is the one that causes an effect on the dependent variable. In this case, the independent variable is <u>depth.</u> Different depths lead to a variation in temperature. 2)<em> depths</em>.
<h3>What are de dependent and independent variables?</h3>
- Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results.
This variable is not affected by any other one but influences or causes a reaction in other variables.
- The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one.
Its response might be either directly proportional or inversely proportional to the change in the independent variable.
Now let us answer the question.
The aim of the study was probably to analyze how temperature changed with depth.
So, according to this, depth influenced on the temperatureof water.
- The independent influencing variable is <u>depth</u>.
- The <u>dependent affected variable</u> is water temperature.
The correct option is 2. depths.

Answer:
Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.
Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.
The answer is D) herbivores

Answer:
The correct answer is - option A. 1 (ovary).
Explanation:
Oocytes or egg are produced in the ovaries during the process of the female gametogenesis in female reproductive system. Ovaries are located on each side of the uterus that are oval and small in shape and size and located lower abdomen.
Among other female reproductive organs these are located above others. The ovaries produce oocytes and hormones It is the site at which primordial germ cell (PGC), become primary oocytes.
Thus, the correct answer is - option A. 1 (ovary).
