<em>yes it is right because if we take example of viruses and germs .. new germs and viruses are much modified as compared to old ages because they adopted the ways they can escape from the immunity.. they have an adoption to transmit their DNA material ,also they can take protein coat of host because of which host's immunity cells cannot recognize germs as foriegn particle..and in this way germs and viruses remain for a long time in body due to the adoptations according to age and environment..</em>
Answer:
The correct answer is - Roots allow plants to obtain water and nutrients, while shoots allow plants to obtain gases and sunlight.
Explanation:
Plants have two major parts of the body normally root and shoot. roots are the parts of plants that usually present under the ground and absorbed the essential nutrients and minerals for the life of the plant. Water is also absorbed by the roots that are used in the various processes such as transpiration and photosynthesis.
The shoot includes stem and leaves and responsible for the exchange of gases, particularly taking in carbon dioxide and removes oxygen with help of stomata. These also absorbs sunlight with help of chlorophyll present on the leaves.
Mitochondrion
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
The answer is <span>c. within the krebs cycle.
Oxygen from the lungs enters the blood through which is transported to every cell of the body. From the cells, carbon dioxide is taken to the blood and transferred to the lungs. Carbon dioxide is produced within the Krebs cycle in the cells. Two reactions of the Krebs cycle give carbon dioxide as product:
1. transformation of D-Isocitrate to </span>α-ketoglutarate,
2. transformation of <span>α-ketoglutarate to Succinyl-CoA.</span>
