Answer:
Explanation:
A microscope is an instrument which is used to see the objects which are tiny and difficult to observe through naked eye. The microscope magnifies these objects and enlarge their size. It has two lenses that are ocular and objective.
The magnification for 10X ocular lens and the 40X objective lens is expected to produce the total magnification of 400X (10 x 40 = 400).
Answer: changed by molecular oxygen
Explanation:
Biologically induced molecular oxygen (dioxygen, O2) started to accumulate in Earth's atmosphere and changed Earth's atmosphere from a weakly reducing atmosphere to an oxidizing atmosphere.
Answer:
It occurs out side of mitochondria-(the krebs cycle takes place in mitochondrial matrix
Explanation:
-(the krebs cycle takes place in mitochondrial matrix
Explanation:
The exchange of gases between the blood and tissue cells is internal respiration. Finally, the cells utilize the oxygen for their specific activities: this is called cellular metabolism, or cellular respiration. Together, these activities constitute respiration.
The horse and mouse are endotherms among them rat will have high mass-specific metabolic rate.
The shark and fish are endotherms among them fish will have high mass-specific metabolic rate.
Explanation:
The endotherm (heat requires in them to maintain internal temperature of the body) organism have high metabolic rates to maintain homeostasis, this requires the large amount of energy. Smaller animals have the greater surface area to volume ratio, hence more heat loss and higher metabolism. In larger animals body volume increases, surface area increase is also very slow, hence less heat loss and lower Metabolic rate. Smaller animals exchange oxygen to tissues at a high rate.
Same goes with ectotherms the larger the animal the smaller is the metabolic rate. During winters their activity slows down as they cannot adjust with the temperature of the surrounding.
However metabolic rates of ectotherm and endotherm cannot be compared.
