15. B.
16. G. schlerenchyma cells
17. D. ATP
Answer:
Heat Energy
Explanation:
When energy is transformed from one form to another, or moved from one place to another, or from one system to another there is energy loss. This means that when energy is converted to a different form, some of the input energy is turned into a highly disordered form of energy, like heat.
Hope this helped! :^)
Answer:
Explanation:
The complete question is as follows :
Animals that maintain internal body temperature using heat generated by their own metabolism are called:
A)thermoregulators.
B)hibernators.
C)aerophiles.
D)endotherms.
E)dormants.
- An animal that is capable of maintaining a body temperature that is metabolically favorable for the organism is known as an endotherm.
- The body temperature is maintained by an endotherm by using its internal body capacity to generate heat rather than depending on the ambient temperature.
- Some of the mechanisms used by endotherms to maintain a suitable internal body temperature include shivering, uncouple oxidative phosphorylation, sweating, flushing, etc.
- The endotherms include birds and mammals.
- The ability to perform endothermy is owed to the presence of a large number of mitochondria that enables the organism to increase the rate of metabolism to generate heat as and when required.
Answer:
Reforestation and afforestation
Explanation:
Reforestation is planting trees to restore the forest area while the process of afforestation refers to plantation on a new barren land that is devoid of ant trees. Trees reduce the air pollution by taking in carbon dioxide for photosynthesis and releasing oxygen gas in air. Hence, reforestation and afforestation are effective strategies to reduce the air pollution.
