Heterogeneous mixture is a mixture that is made up of different substance that remains physically separated which means the cell organelles (Red blood cells, white blood cells, platelets etc.)present in blood does not mix completely and hence get precipitated after kept still for a while.
There are three ways to identify a Heterogeneous mixture.
- It has chunks of stuff that you are able to see with your eyes.

- After a while, the substance will separate into layers at settle at the bottom(gets precipitated).
Result: Blood is a Heterogeneous mixture
Ans.
In human body, three types of blood cells are present, which include red blood cells, platelets, and white blood cells. Although these cells are started out alike, they show different shapes, sizes, and functions due to instructions that differentiate them into different types. These instructions are given by particular chromosomes present in the cells as the chromosomes consist of DNA that provides information to the cells, which is responsible for characteristic behavior of that cell.
Hence, the correct answer for the blank is 'B) chromosomes.'

The rows of bushes
Explanation:
<em>The experimental unit in this experiment would be the rows of bushes in the field.</em>
<u>By definition, experimental units are considered physical entities that can randomly be assigned to varied treatment regimes during the course of a research.</u>
In this case, the entity that are given different treatment condition during the process of experimentation are the rows of berry bushes within one of the several fields. Half of the rows were covered with nets while the remaining half were left uncovered.
<em>The rows were given different treatments and hence, considered the experimental units in this particular experiment.</em>
The correct option is c.
