It is fact not supposition .
would you expect skin cells to contain more or fewer mitochondria than muscle cell?
Red blood cells do not contain mitochondria, they are designed to deliver O2 via their complex heme centers & thus contain no nucleus/organelles, maximizing space for this job. Red blood cells arise from bone marrow stem cells & only circulate, carrying O2 for about 120 days before the spleen recycles their heme groups.
when a person has fewer red blood cells than normal his or her color is yellowish
Our muscle cells are what enables physical exertions, such as lifting, running or even standing. With so many strenuous functions, muscle cells need a lot of energy to keep running efficiently. The mitochondria are the powerhouses of the cell. They produce a high energy compound known as ATP. In the case of skin cells, which serve a protection and sensory purpose, they need far fewer mitochondria to run at their best.
white blood cells have nucleii (unlike red blood cells) and do not contain hemoglobin (again, unlike red blood cells). they are irregularly shaped, and there are fewer of them in the body.
Mitochondria are the organelles within a cell that house the enzymes that are involved in aerobic cellular respiration. Cell types that have a high demand for ATP (such as muscle cells) have many mitochondria while cell types with a low demand for ATP (such as osteocytes) have fewer mitochondria.
requires less energy then thyroid tissue
Muscle cells are very active relatively to the skin cell. So it has more mitochondria

The concept of having a normal blood. Red blood cells as compared to the white blood cells are really more numerous. Normally, human blood contains about 3.6 to 6.2 x 1012/L red blood cells while while blood cells only reaches 5-10 x109/L.
Bacterial cells don't perform the krebs cyce or oxidative phosphorylation steps of cellular respiration and therefore do not need mitochondria. Bacteria only perform glycolysis which is done in the cytoplasm to convert glucose into ATP to drive cellular work.
