Answer: D
Explanation: when gasoline is burned by the car, it releases gas which pollutes the air.
Answer – Chromosome
In eukaryotic nuclei, DNA and proteins are packaged into organized cellular structures known as Chromosomes. Genetic material is housed in the nucleus where is it tightly packed into linear chromosomes. Chromosomes consist of a complex of DNA and protein which is known as chromatin. Chromatins are organized into subunits called nucleosomes
Answer:
C. Vaccination
Explanation:
vaccination is the administration of a vaccine to help the immune system develop protection from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism.
The molecule, which the plant is most likely synthesizing using the extra nitrogen is PROTEIN.
Plants and animals do not have the capacity to use atmospheric nitrogen as nutrient. Atmospheric nitrogen has to be converted to forms that are usable by plants and animals before they can utilize it. Nitrogen fixing bacteria are the ones that are responsible for converting atmospheric nitrogen to the forms such as nitrate and ammonium, which can be used by plants. Animals get their own portion of nitrogen when they eat plants or other animals. Nitrate is the form of nitrogen that is mostly used by plants. Excess ammonium in plants are usually used directly to synthesize proteins. Nitrogen is a very important component of chlorophyll, which is essential for photosynthesis. Nitrogen is also found in the genetic materials of plants and it is needed for their growth and development. Animals used nitrogen to synthesize proteins, nucleic acid and other biological compounds that contain nitrogen.
