Prokaryotes are the Earth`s firs living things. This are the simplest life forms exhibiting ( showing ) cellular structures.
They exist in 2 major forms:
- Eubacteria ( most of the common bacteria that are found everywhere ),
- Archaebacteria ( ancient bacteria that live in very extreme conditions ).
Answer: Prokaryotes.
I would agree with your answer of C. As there would need to be calcium to start with and they seem to come from the sarcoplasmic reticulum
Answer:
The amount of fossil fuels formed is much less than the amount used.
Explanation:
Fossil fuels, which include petroleum, coal, natural gas etc are an example of non-renewable sources of energy. They are termed non-renewable because they are sources that gets exhausted quickly without replenishment.
One of the characteristics of non-renewable sources of energy is that they get exhausted faster than they can be produced. Hence, regarding fossil fuels as an example of non-renewable source of energy, this means that the amount of fossil fuels formed is much less than the amount used.
Answer:
The correct answer will be- to synthesise the ATP molecules in respiration process.
Explanation:
The electron transport chain is the last phase of the cellular respiration which helps in the synthesis of a large number of ATP molecules.
The ATP molecules are synthesized when the energy generated by the movement of protons through CF₀ unit takes place.
The movement of electrons in the chain leads to the movement of proton from the mitochondrial matrix to the intermembrane space. This creates the proton gradient across the membrane which to equilibrate the protons move down the concentration gradient through ATP synthase. The energy while this is used to rotate the ATP synthase which coverts the ADP to ATP.
Thus, to synthesise the ATP molecules in the respiration process.
