The correct answer is option 4, that is, muscle cells require more energy, so they have more mitochondria in comparison to the skin cells.
Mitochondria are the powerhouse of the cells. The synthesis of ATP takes place in them, that is, the energy currencies of the cell. The cells of the muscles need to work hard and thus require ample energy, for this, they need more concentration of mitochondria to generate a high energy yielding ATPs.
Answer:
Natural selection is a theory originally popularized by Charles Darwin. According to this theory, animals in the natural environment change over time as beneficial traits are preserved, and traits which do not advance the species are slowly weeded out. Natural selection, a concept first theorized by Charles Darwin, is the adjustment of genes throughout generations based on factors that help it survive. Sometimes this is survival of the fittest or the organisms that are better suited to the environment in other ways.

C would be the correct answer because The glacial budget refers to the balance between the amount of inputs versus outputs affecting the glacial system. So the glacier loses mass as evaporation will increase due to warmer temperatures and there will be melting at the snout. This part of a glacier is known as the zone of ablation.
Unicellular organisms
Explanation:
Unicellular organisms typically respires faster to release energy.
Respiration is a gaseous exchange between cells and the environment. Here, oxygen is taken in by the cell and carbon dioxide is the by product of the metabolic process.
- Unicellular organisms will respire faster because they are at the lowest level of organisation.
- The cells are in direct contact with the environment.
- They do not require special set up to obtain and circulate oxygen in them.
- The waste of the metabolic process is also discarded easily and very fast.
- Organisms at lower levels of organisation typically have a faster rate of respiration.
