Answer:
amino acids
anaerobic respiration
aerobic respiration
lungs
liver
kidneys
nitrogen
toxic
Explanation:
Excretion refers to the removal of waste products that is produced from amino acids metabolism.
Carbon dioxide is formed in living organisms in the process of both aerobic respiration and anaerobic respiration and can be removed from the body through lungs.
Urea is produced in the liver and then the blood is to be sent to the kidney and which is excreted from the body.
Urea is compounds of nitrogen which is formed from amino acids that contains toxic substances which the body does not need.
Primary succession occurs over time. the soil depth increases due to decomposition of plant matter and there is a gradual increase of species diversity in the ecosystem.
Answer:
Option d ; energy
Explanation:
Energy is the main component of life. From simple processes such as photosynthesis, to the production of plants, to reproduction in mammalian life, all depend on the life-driving force of energy.
In the bear's life, the energy is needed for cellular processes like respiration, particularly the Krebs Cycle. Not only that, because bears live in polar regions, they need heat to keep them warm. Without energy, they will not be able to move, hunt or sustain themselves.
The troposphere, as altitude increases in the troposphere the amount of water vapor decreases.
<span>I'm not sure, but I know that their colour changes as the fish matures.
"Young fish are bright yellow with blue spots near their eyes. As they get older, they become blue over most of their body with a yellowtail. Full-grown adults are a rich blue from head to tail, with narrow dark lines running the length of the body."
