Answer:
The dependant variable is the growth of the plants.
Explanation:
The independent variable is what changes the dependent variable.
for example, the type of salt concentration ( Independent variable ) is/ isn't going to change the growth ( dependant variable ) of the plant.
Answer:
Fossils generally helps in relative dating of rocks.
The Trilobites are considered the oldest in this rock sequence when we apply the principle of superposition of strata.
The principle states that "in an undeformed/undisturbed sequence of rock, the oldest is always at the bottom while the youngest is on top" .
This principle therefore explains why the Trilobites at the base are considered the oldest.
Gymnosperms are the vascular plants that produce seeds produced over the reproductive structure but are not enclosed in the fruits and are found in the cones.
<h3>What are Gymnosperms?</h3>
Gymnosperms are the plant variety that reproduces in the form of exposed ovules or seeds that are not enclosed but are not visible till maturity. They are generally of short height and have tap roots.
They are heterosporous as they bear two types of spores, microspores, and megaspores. Also, they lack beautiful flowers and are pollinated through the wind. The seed produced as a result has haploid endosperms without any covering.
Therefore, the gymnosperms do not have their seeds enclosed.

Answer:
Water is one of the basic constituent for life. It makes up 60 percent of the human body weight.By analyzing the human body we came to know that water is one of the building blocks in making up most of cells and tissues.
Now there are some specific functions of water inside the human body.As some of the functions are as below.
Explanation:
<u> "Medium for transportation"</u>
Water mainly acts as a medium for transportation of different materials inside a body. But, there are also some other operations for water to carry out inside human body.
"<u>Lubrication of Joints"</u>
Water helps in keeping the human body joints healthy and lubricated. The lubrication is important to reduce any friction during motion.
"<u>Water Homeostasis" </u>
Human body needs an equilibrium when it comes to the level of materials it posses. For that reason <em>water homeostasis </em>is carried out, in order to have an optimum amount of water inside human body.
<u>Temperature Regulation</u>
The optimum temperature for human body to operate well is about 37 degree centigrade which is about 98.6 Fahrenheit. Now water can regulate the temperature by initializing excessive sweating and through urinating or even avoiding the two operations mentioned before to avoid water loss.
Endoplasmic Reticulum
The ER has two major functions: Transport: Molecules, such as proteins, can move from place to place inside the ER, much like on an intracellular highway. Synthesis: Ribosomes that are attached to ER, similar to unattached ribosomes, make proteins. Lipids are also produced in the ER.
