Option C. Particle Size.
This can be explained as:
Sand and gravel have two different sizes and can be separated on the basis of particle sizes.Sieving is a method that can be employed to separate gravel from sand.Sand particles being small will pass through the sieve while gravel being big in size will remain on the top of the sieve.Therefore, particle size will be the parameter by which sand and gravel can be separated.

O3) the distance it has to travel.
O4) AIl of the answers are correct.
Answers
The direction of blood travel can be determined by the shape of the blood drop. Therefore, option B is correct.
What is blood pattern analysis?To ascertain what actions could have produced the bloodstains and/or patterns shown, bloodstain pattern analysis studies are carried out.
Bloodstains can be divided into three categories: projected or impact stains, transfer stains, and passive stains. Passive stains, which can take the form of droplets, flows, and pools, are frequently caused by the weight of an injured body.
In order to determine if it is human blood and then create a DNA profile, analysts or investigators frequently soak up pooled blood or swab small quantities of dried blood. When there are numerous victims, this becomes extremely important. Thus, option B is correct.

A) cytokinesis.
B) cell cleavage.
C) cell differentiation.
D) gamete fertilization
Answers
Answer:
C) cell differentiation.
Explanation:
Cell differentiation is a process undergone by a cell in which it changes to a specialized form. During the process of cell differentiation, some genes in a single cell becomes turned off or on in a process called GENE EXPRESSION to give rise to cells with specialized functions.
This is the case of this sponge whose specialized cells perform unique functions like ingesting food, support, and reproduction. The specialization of the cells within the sponge is as a result of the process of CELL DIFFERENTIATION.
