Answer:
haploid/diploid
Explanation:
The number of chromosomes can also be expressed as <em>haploid or diploid</em>, instead of 1n for one copy and 2n for two copies.
The <u>haploid number of chromosomes also refers to a copy of the chromosomes or half of the genome of organisms</u> while <u>the diploid number of chromosomes refers to the double or complete set of chromosomes in the genome of organisms. </u>
So, in other words: n = haploid and 2n - diploid.
Answer:
The body's cells use oxygen for metabolism, and this process creates the waste product carbon dioxide. With the help of the lymphatic and circulatory systems, the skeletal system works with the respiratory system by creating red blood cells in the bones that aid in respiration facilitated by the lungs.
Answer: CO2 in the atmosphere
Explanation:
During photosynthesis, plants removes carbon dioxide in large amount from the atmosphere and then utilize the carbon atoms to build up organic molecules.
Thus, this removal of CO2 from the atmosphere provide a natural solution to prevent the gas accumulation in the atmosphere, which is often generated by human activities and natural causes.
