Answer:

  D.  Polaris and Sirius are farther away than the Sun.

Explanation:

The radiation intercepted by Earth is inversely proportional to the square of the distance from the source. Polaris and Sirius are substantially farther away than the sun.

Polaris, for example, is about 27 million times farther away, so even though it is 4000 times brighter, we receive on the order of 5×10^-12 as much radiation from that star as from the sun.

We feel less heat from stars other than the Sun because they are farther away.

In which cell structure does MOST of the process of cellular respiration take place?
ahrayia [7]

Mitochondria are rod-shaped organelles are basically considered the power producers of the cell, it converts oxygen and nutrients into adenosine triphosphate or ATP, which is the chemical energy,also known as "currency" of the cell which powers the metabolic actions of the cell. This process is called aerobic respiration and it is the reason animals breathe oxygen. Cellular repiration happens in the mitochodrion. The 3 phases of cellular respiration are Krebs Cycle, Electron Transport and Glycolysis (Fermentation). Glycolysis takes place in the cytoplasm while the Krebs cycle and electron transport take place in the mitochondria.
