Answer:
According to scientists , water occupies up to 60 % of the human body .
The importance of water in the human body are ;
- Transport
- Formation of bodily fluids i.e. saliva
- Digestion
- Regulates body temperatures
- Circulation of nutrients
Explanation:
The reason why it is important to maintain good fluid balance within and without he cells is because , It can dissolve various elements to make then easily absorbed into other system .There are many fluids which rely on water for volume e.g. blood which is the main component of the circulatory systems , water also regulates the temperature and heart pressure ,
Through electrolysis , fluid balance in the cells can be achieved and it also helps to generate nerve impulses .
Answer:
D. Making a prediction.
Explanation:
In many cases, the words "hypothesis" and "prediction" are used in the same context. However, in science, they do not have the same meaning.
A hypothesis is an <u>intelligent, testable, and possible explanation that is based on facts</u>. It analyzes the correlation between different variables.
A prediction, on the other hand, is usually <u>based on little or simpler information instead of experiments or scientific facts and are generally related to future events, therefore, in many cases, they tend to start with the word "If" or have the word "then" on the statement.</u>
In this case, "<em>If ferns need warm weather to grow, ferns in the warmer areas will grow faster</em>," this is a simple prediction that is not necessarily based on scientific facts. It is making a possible prediction or pure guess. This is also illustrated by the usage of "if" on it.

Answer:
C
Explanation:
Green Plants are the main producers of starch as carbohydrate.In order to carry out this special organelle Chloroplast are specially adapted for this purpose,
Green plant are made up of Chlorophyll which are the green pigments that for trapping sunlight for the synthesis of starch to occur.
Photosynthesis is the process of synthesis of the starch.It involves the reaction of C02 with water in the presence of sunlight and enzymes to give oxygen as the byproduct, and Starch( carbohydrate) as the main product.
This process occur in two pathways the light dependent pathways and the light independent pathways,
Green plant and some organisms phytoplankons,algea are capable of producing starch through photosynthesis because of the green pigment they possess.Therefore they are said to be Autothrophic.
