Answer:
All of the above
Explanation:

background info:
Digestive system in animals is an important system in the context of digestion of ingested food into simpler forms that could be easily absorbed by the body cells.
This provides all the essential compounds needed by the body for the existence and development of the living organism. Different digestive systems have evolved according to different species, their feeding patterns, and their habitats.
answer:
Ruminant species survive only on plant matter. They are herbivorous animals.
Therefore, the digestive system of ruminants is evolved with the presence of a rumen which is a complex stomach with four different compartments.
Humans are omnivorous who depend on plant and animal matter both thus, their digestive system composes of one stomach.
This is the key difference between digestion of humans and ruminants.
hope this helped
Answer:
The correct answer is-forcing blood from the heart into the major arteries
Explanation:
Heart is not made up of smooth muscles rather it is mainly made up of a specialized type of muscle called cardiac muscle which helps in the contraction of heath that results in the forcing blood from the heart into the major arteries.
Cardiac muscle is straited muscle but smooth muscle is not straited muscle. These smooth muscles are mainly present in the organs which have hollow walls like urinary tract, digestive tract, blood vessels, etc.
Therefore forcing blood from the heart into the major arteries is not a function of smooth muscle tissue.
Answer:
The most important feature that permits a gene to act as a molecular clock is having a reliable average rate of mutation.
Explanation:
The molecular clock is also known as the “evolutionary clock” or “gene clock”. These was studied by scientists suchs as Darwin, and it made possible for paleontologists to study humanity evolution. <em>Through this idea we talk about the biological concept of heredity: we inherit information in the form of genetic molecules (usually DNA) from the previous generation</em>. This is possible thanks to Mutation. In mutation, DNA and protein sequences evolve DNA and protein sequences evolve over time and among different organism.
