Answer:
When water falls and seeps into the ground it actually interacts with the lithosphere
Answer: A. The genes encode resistance to antibiotics.
D. The genes are carried on plasmids
F. The "clock"genes are highly mobile between species.
Explanation:
Molecular clock is a tool that is used to calculate the time of the evolutionary events. These are the gene sequences that are used to determine the evolutionary distance between the new and primitive organisms developed on earth. It also measures the random changes just like mutation. Thus the molecular clock is also called as the gene clock or evolutionary clock.
The accuracy of the molecular clock can be increased by the genes that encode for a resistance against the antibiotics, the genes that are carried on the plasmids and the clock genes which are highly mobile among the species.
Answer:
B. Sea stars are the prey of seagulls
Explanation:
Seagulls eat sea stars, meaning that sea stars are their prey (the organism that is eaten).
Predator: an organism that eats (preys on) another organism
Prey: an organism that is eaten by another organism (creatures can be both predator and prey. For example, a rabbit is a predator to grass, while they are prey to foxes)
Host: An organism that is fed on by a parasite. Think of a dog with a tick. The dog is the host, the tick is the parasite.
Incorrect answers (and why):
A. Sea stars do not eat seagulls
C. If a sea star was a predator to a seagull, that would mean that they eat seagulls. They do not.
D. A host is an organism that a parasite preys on. Not only are sea stars not parasites, but they definitely do not prey on seagulls.
I hope this helps! :)
Secondary consumers may be carnivores that eat meat or omnivores that eat both plants and animals.
<h3>What are secondary consumers?</h3>
Consumers in biology are organisms (heterotrophs) that uses other organisms for food in order to gain energy.
Consumers can either be primary or secondary. Primary consumers feed directly on plants, hence, are said to be herbivores.
On the other hand, secondary consumers feed majorly on primary consumers, making them carnivorous in nature.
However, secondary consumers may be carnivores that eat meat or omnivores that eat both plants and animals.
