<h2>
Answer:</h2>
The scientist started to study relationships among various groups of organisms <u>C. by using genetic analyses</u>.
<h2>
Explanation:</h2>
The following features were used to study about the relationships between different groups of organism:
- External morphology
- Similarities in structure
- Genetic analysis
- Chemical composition
The molecular similarities in the structure of RNA, DNA, and proteins help to establish the relationship of relationships between different groups of organisms. This was studied through testing the samples obtained by organisms using genetic analyses.
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! :)
Answer:
Hello. C is the correct answer.
Explanation:
Before reaching M phase in cell cycle ،in S phase the DNA replicates. So we have two double strands DNA like each other so when the cell enters mitosis. Two cell will produced which are geneticly simmilar to parent cell.
Hope you understand.

Hello there,
Qn 1: D, Fewer pests will enter the environment- because the crops are genetically modified to prevent insects from consuming them.
Qn 2: D, How the genetic code of cloned organisms differs from other organsims. -scientists must ensure that codes of genetically modified organisms are totally different from the original organisms.
Hope this helps :))
