The answer is B
Explanation: RNA is single stranded and contain uracil
Answer:
b) electron transport chain
Explanation:
During sprinting, muscles need a constant supply of ATPs (the energy currency of cells) to support the continuous movement. The electron transport chain is present in the inner mitochondrial membrane.
Oxidation of NADH and FADH2 through electron transport chain produces proton gradient across the membrane which in turn drives the synthesis of a large number of ATPs to support sprinting.
If producers were removed from an ecosystem, it would fall apart. Producers are the organisms at the bottom of the food chain, which produce glucose and nutrients for consumers. If producers were removed from an ecosystem, the consumers would have no nutrients and die, causing their predators to die, and so on.
Answer:
there are two types of cell one eukaryotic cell that have true nucleus (genetic material enclosed in membrane) and membrane bounded organelles and other is prokaryotic cell that donot have have true nucleus (genetic material dispersed in cytoplasm) and membrane bounded organelles.
similarities between PC and EC is that both contains cell membrane, ribosomes (not a membrane bounded organelle) .
examples of PC are bacteria , paramecium,fungi etc
examples of EC are plant and animal cells
there are two names for cell membrane i.e plasmalemma, cell surface membrane,
selectively permeable or semipermeable means cell only allows those material to pass through its cell membrane which it needs.this cell'ability is important because to protection against the poisonous substance and to maintain cell needs .
