Im not 100% sure but i want to say main sequence stars
it is a.cell because tissues, organs and organisms are larger than a cell so 'a' is the correct answer
Cellular respiration is the process that take place in the mitochondrion of a cell, it involves use of glucose from photosynthesis to produce energy in form of ATP and formation of CO2 and water. In this case, the Carbon dioxide formed passively diffuses out of the cell and Oxygen is pumped in and forces CO2 out. In this process oxygen acts as a electron acceptor.
The genotype describes the complete set of genes inherited by an individual, and the phenotype describes all aspects of the individual's morphology, physiology, behavior, and ecological relations. Light, water, temperature, soil structure are the environmental factors which influence the plant phenotype most. The growth is a very sensitive phenotypic trait that quickly responds to any sub-optimal environment. However, many more physiological responses occur that turn out in phenotypes that can be measured with non-invasive technology.
