<span>The key points about cell theory are as follows:
1. All living organisms are made up of cells; the organisms may be unicellular or multi cellular.
2. The cell is the basic unit of life.
3. New cells are derived from pre-existing cells.
4. All cells maintain homeostasis.
Some new facts have been added to these basic facts; the new facts added include the following:
(A). Energy flow occur withing all living cells.
(B). Hereditary information derived from DNA is passed from cell to cell.
(C). All living cells are made up of the same basic chemical compositions.</span>
Answer:
After watching a plant for a week, you determine it needs more sunlight.
Explanation:
Inference is a process by which, through certain data, a conclusion is reached. Other synonyms for inference are conclusion, implication, ilation and consequence.
Accordingly, an inference is made when after watching a plant for a week, you determine that it needs more sunlight. This was a conclusion based on data.
Not all inferences offer true conclusions, even with data analysis. It is possible to state that all dogs are furry animals with four legs, but it cannot be inferred that all furry animals that have four legs are dogs.
Inferences usually arise from an analysis of characteristics and probabilities. If someone makes reference to an animal with four legs, hairy and wagging its tail, it can be inferred that the most certain thing is that it is referring to a dog.
According to the Big Bang theory, the universe was once very dense and is now expanding.

Explanation:
The introduction of electric charge into a gel or fluid, causing or resulting in the movement of the charged particles in the gel or fluid, is referred to as the electrophoresis. It can also be explained as a separation method or technique which is based on the movement of particles or ions in an electric field.
The electrophoresis is used in separating DNA fragments , RNA or protein, based on their size and charge.
Clouds form as a result of the condensation of water vapor in the atmosphere. They are made of tiny droplets of water. Clouds tend to form between 3pm and 6pm because this is when the region starts to loose or has completely lost the heat form the daily sun. Water vapor will condense once temperatures are low or are decreasing.
