Answer:
True
Explanation:
ATP – or Adenosine Triphosphate – is the primary energy carrier in all living organisms on earth. Microorganisms capture and store energy metabolized from food and light sources in the form of ATP.
When the cell requires energy, ATP is broken down through hydrolysis. The high energy bond is broken and a phosphoryl group is removed. The energy released from this process is used to drive various cellular processes. ATP is constantly formed and broken down as it participates in biological reactions and it is central to the health and growth of all life. Without it, cells could not transfer energy from one location to another, making it impossible for organisms to grow and reproduce.
ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose.

On a global scale, energy flows through ecosystems whereas chemical elements are recycle in ecosystems. So the answer is the third option.
Energy flows through the ecosystem. Most energy comes from sunlight and it is transformed into chemical energy by autotrophs. When they are consumed by heterotrophs the energy is passed on, until it dissipates as heat.

Chemical elements like carbon and nitrogen, on the other hand, are cycled between biotic and abiotic factors in an ecosystem. This is not possible for energy. These chemical elements come from abiotic factors like the air, light and soil. They are incorporated in the biomass of the photosynthetic organisms and are consumed by other organisms. They are changed back into their inorganic form when the organism dies and are broken down by decomposers and the cycle goes on. So they are constantly being recycled.
In summary, energy needs a continuous source to be able to maintain and sustain the energy flow in the ecosystem. Chemical elements, on the other hand, are just recycled through processes between abiotic factors and biotic factors. </span>
If you are conducting a study on the health of people who have been exposed vs not exposed, the method you should use to obtain data would be an observational study because it involves the pre-existing condition of the subjects.
The correct answer is: In trisomy there would be one extra chromosome; in a duplication, the number of chromosomes would be normal, but one chromosome would have two copies of a portion of the chromosome.
Trisomy is a type of polysomy (chromosome aberration with extra number of chromosome/s) and also type of aneuploidy (an abnormal number of chromosomes).
Instead of the normal two (one from mother one from father) chromosomes, people with trisomy have three chromosomes. This condition occurs when chromosome pairs fail to separate properly during cell division.
Duplication, on the other hand, usually refers to a region of DNA that is being duplicated. This condition occurs as products of several types of errors in DNA replication and repair machinery.
Answer: when a person becomes infected with HIV the body responds by trying to eliminate the virus. This is the job of the immune system, and one way the immune system tries to get rid of viruses like HIV, is by making antibodies. ... Other immune system cells eventually destroy this antibody-and-germ pair.:
