The answer should be C, It diffuses from the alveoli into the blood.
Alveoli, also called the air sac, is the place where the oxygen we breathed in is exchanged with carbon dioxide that our body produces. Oxygen is passed into the blood in the capillaries through the process of diffusion, while carbon dioxide is diffused from the blood back to the alveoli, so that we can exhale the carbon dioxide after that.
Both a and b are not right because when we breathe in, the oxygen travels from the trachea to the bronchi, to the bronchiole, and to the alveoli, instead of directly into blood vessels like arteries, capillaries, or veins. d is also not right because the direction is wrong.
Therefore, your answer should be C.
Oxygen and glucose are required for the mitochondria to properly undergo cellular respiration.
Answer:
This statement is best described by the option B. The recombinant DNA produced by the combination of a vector and gene of interest in the E.coli which produces multiple copies of this recombinant DNA along with the chromosomal DNA and expresses the gene.
Explanation:
In genetic engineering, the gene of interest is combined with a vector e.g. plasmid and inserted into the most suitable carrier for these recombinants. This carrier acts as the manufacturing unit for the gene of interest as it produces multiple copies when it replicates in a short period of time. E.coli is considered to be one of the best manufacturing units in the field of genetic engineering as it has a very flexible replication time.
The change in the behavioral as well as the feeding patterns by 2 or more population competing for reducing interspecific competition which is also called as the character displacement is niche shift which is the answer.Hope this would help and this is the right answer.
