Yes because more of them are gone
Cells get energy by breaking down food molecules to release the stored chemical energy by a process called 'cellular respiration'.
During the process Oxygen is used to oxidize food, that oxidized food is known as glucose.

Answer:
D. It is able to form colonies and produce oxygen.
Explanation:
Cyanobacteria are the photoautotrophs and carry out oxygenic photosynthesis. These prokaryotic organisms use water molecules as an electron donor during light-dependent reactions of photosynthesis and release oxygen gas as a by-product.
Cyanobacteria are considered to be the first organisms on the earth to perform oxygenic photosynthesis and are supposed to be responsible for the present-day oxidative atmosphere of the earth. Most of the cyanobacteria are colonial forms and are present as colonies of a large number of cells. However, unicellular solitary forms are also present.
Answer:
hereditary only: DNA replication, anaphase I,II and metaphase II.
genetic variation only: crossing over, -metaphase 1
both: fertilization
Explanation:
hereditary only: DNA is only copied to have enough for the daughter cells.
Anaphase I, II chromosomes are moving to be inherit to daughter cells.
Metaphase II chromosomes were sorted randomly during metaphase I and will only line up to move to each daughter cell.
Genetic variation only: during crossing over chromosomes exchange information which accounts for DNA variability.
During metaphase I random assortment of chromosomes will create variability too.
Both: during fertilization the newly formed zygote contains different information from both parents (genetic variation), and this information is passed onto the next generation.
