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.

Sponges, members of the phylum Porifera, are sessile filter feeders that lack tissues or organs. Instead, specialized cells have unique functions like ingesting food, support, and reproduction. Such specialization within a sponge body is a result of
A) cytokinesis.
B) cell cleavage.
C) cell differentiation.
D) gamete fertilization
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.

Explain how the conversation of wetlands to farmlands has impacted stream and rivers
Answer:
Wetland reduction has caused a decrease in the absorption zones for excess water. If the excess water cannot be absorbed by the soil, it increases the incidence and magnitude of flooding.
The conversation of wetlands to farmlands has impacted stream and rivers as the Wetland reduction has been caused the decrease in the absorption zones for excess water.
