Answer:
B. interconnected
Explanation:
All the systems in our bodies (humans are indeed animals) are connected with each other to create a functional being. The blood flows throughout the body, providing nutrients; the bones support the structure and protect the heart and lungs. They work together.
Why not A: The systems are all completely necessary. There's nothing extraneous in our bodies, because extraneous stuff takes up energy, and our biology is incredibly economical.
Why not B: They're not interchangeable. How would you like your bones to turn to blood? Uh-huh.
Why not D: They interact with each other consistently, so they're not separate or segregated.
Answer:
The process which must occur when intending to work with research animals that are covered by the U.S federal regulations is ethical review and approval
Explanation:
Some animals had been threatened of extinction due to inconsiderate usage and killings due to either commercial, food, or research purpose. The U.S government, therefore, to prevent the extinction of such animals, formulated a law to restrict the engagement of these animals, even in research if the research will involve the slaughtering, injuring, or alter the physiological functions of the subject animals. Therefore, there has been needing to undergo a compulsory ethical review process when planning to undertake research. This process will objectively review the aims and objectives of the intended research, the methodology involved in achieving the aim, as stated in the research proposal. The importance of this review is to determine if the research will have deleterious effects on the animals, both spontaneously and in the future.
Answer:
RNA Polymerase is the enzyme responsible for the synthesis of RNA
Explanation:
Ribonucleic acid [RNA] is synthesized from DNA in a process known as transcription. this process is facilitated by RNA polymerase enzyme. The corresponding RNA produced is complementary to the parent DNA
While DNA is usually double-stranded, RNA is single-stranded and they are synthesized from each strand of DNA.
RNA polymerase is responsible for unwinding the double strands of DNA and copying the information into the newly formed RNA strand.
