Answer:
The correct answer would be "NADH delivers its electrons to complex I and FADH₂ deliver its electrons to complex II" in cellular respiration.
There are mainly four complexes associated with electron transport chain of cellular respiration.
Complex I or NADH: ubiquinone oxidoreductase is the complex at which NADH is oxidized to form NAD⁺. The free electrons are transported with the help of ubiquinone.
Complex II or succinate dehydrogenase is the complex associated with oxidation of FADH₂ to FAD⁺. It also transports the free electrons with the help of the ubiquinone pool.
Complex III or cytochrome bc1 complex transport free electrons from ubiquinone to the cytochrome C which is a water-soluble electron carrier.
Complex IV or cytochrome c oxidase transport the free electrons to oxygen to form water.
Explanation:
In the analogy of a cell as a school, lysosomes could be thought of as a teacher.
Because teacher helps students by solving complex problems in simple way and as teacher lysosomes also helps us by breaking down the complex thing in the cell.
The answer is B. Organisms in boxes 5 and 7 fit the description.
Answer:
Climate change has the effect of determining migration of people.
Explanation:
A hazardous environment eg. changes in rainfall patterns, increase in temperature, sea level rise, cyclone frequency has the effect of people migrating to cooler places whereas a conducive environment has the effect of attracting more people to settle there.
The energy of the ecosystem can be best described as option C. The amount of energy entering an ecosystem from the Sun is equal to the amount used by organisms plus the amount lost as heat.
