Answer:
Explanation:
An empirical evidence illustrates facts that are drawn from experimentation and observations. These are usually drawn from the way we see and percieve our environment using our senses.
A hypothesis is best and simply defined as a scientific guess. It is often a direct product of empirical studies of a particular problem. Most times when scientists gather facts and principles have been formulated, they try to explain their observation. This explanation is the hypothesis. The satement of the hypothesis is usually tentantive. Sometimes, we can have several hypothesis for a common source of empirical evidence.
Answer:
When the required direction of transport is opposed to concentration levels, a cell <u>will </u> expend energy to force<u> ions</u> across its membrane.
Explanation:
If the concentration gradient is opposite to the direction of transport of minerals, then the cell will use energy to transport mineral ions from a lower concentration to a higher concentration. The most common process through which this happens is termed as the active transport.
The process of active transport is opposite to passive transport. In passive transport, molecules move from a higher concentration to a lower concentration.
