Lean body mass <span>is the body mass attributed to non-fat body components, such as bone, muscle, and internal organs. In general, lean body mass is the mass of the body excluding the fat.

Oncogenes result from turning on, or activating proto oncogenes. Proto oncogenes are genes that code for positive cell cycle regulators, so proto oncogenes code for proteins that turn on cell division. Proto oncogenes are normal genes, but when they are mutated, they become oncogenes. Oncogenes are expressed too much, which makes them turn on cell division too much, which is cancer.
The first statement is wrong because photosynthesis occur during day by plants, while respiration happens during day and night which are very related and they can be happened at the same time, in other hand photosynthesis cannot Accor in human cells because animal cells do not have chloroplasts which are using light energy to make glucose ,but in our cells or in animal cells we have mitochondria which break down the energy to make ATP....
for the second statement I'm not sure about that ....
I think that the third statement Is correct, because
the Cellular respiration make carbon dioxide + water + ATP then those would be then used by photosynthesis to make glucose and oxygen .
can I get brainlist pls?
