Answer:
c. Algae to fish to grizzly bear to fungi
Explanation:
Algae are the producers in Yellowstone trophic levels which can be eaten by fish which is a primary consumer. The grizzly bear which is a secondary consumer or carnivores feed on these fish and when the grizzly bear die, fungi which is a decomposer feeds on the grizzly bear and release nitrogenous substances which can be used by the algae for its growth and development. Only 10% of energy is transferred from on trophic level to another whereas the remaining 90% are released in the form of heat energy.
Answer:
Viruses can be used to insert genetic material into cells during gene therapy
Explanation:
Gene therapy is a process used to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.
A gene that is inserted directly into a cell usually does not function. Instead, a carrier called a vector is genetically engineered to deliver the gene. Certain viruses are often used as vectors because they can deliver the new gene by infecting the cell. The viruses are modified so they can't cause disease when used in people.
The answer is radioisotopes as this has the ability of
breaking molecules apart and aside that, it has the ability of destroying cells
and as well as having to damage living tissues in the body because these are
isotopes that are unstable.
Answer:
White eyes are lethal in male Drosophila was the hypothesis of Thomas hunt which was valid. Hence the answer is option B.
Explanation:
Thomas hunt Morgan was a famous American biologist. He was more famous because of his experiment on drosophila which contributed most of things about the lifestyle and health science in much of the findings about those insects.
He was also awarded by the Nobel prize for his works which was related to medicine in 1933. He has also contributed many knowledge about the chromosome and heredity. he is finding is very helpful nowadays for the scientist and other biologist.
That Jupiter, Saturn, Uranus, and Neptune are the outer planets and the other planets are the 4 inner planets.
