Its important not to put a person making an emergency call on hold because since it might be a patient who is a serious case and might lose consciousness.

Additionally its is important to make sure one stays connected with the patient until help arrives to ensure their safety.
Answer:
Option C, cladistics reveals relative evolutionary branching by utilizing genetic analysis
Explanation:
Cladistics classification is a way of classifying organisms biologically in a way that a relationship between their shared traits could be established which leads to identification of closely related organism and species. It further helps to identify ancestry history of closely related species to identify closely related common ancestors and the evolution of various characteristics.
Basically in Cladistics study, species are arranged on a phylogenetic tree based on the time of their emergence from any other group.
Hence, option C is correct.
The term that describes the sheep in this scenario is prey, consumer and primary consumer.
A. Prey
B. Consumer
C. Primary consumers
<u>Explanation:</u>
It is given here that the sheep graze on the grass. Thus sheep is a consumer. When we get into the details of trophic levels in the ecosystem we can understand that autotrophs are the producers of an ecosystem. The organisms that feed on autotrophs are primary consumers.
Here grass is the producer and sheep is the primary consumer since it feeds on the grass. It is also given here that the ranchers have to keep the sheep away from predators. This makes the sheep a prey too. The animals that feed on primary consumers are called secondary consumers.
