Answer:
Stage two: carbon fixation
The ATP is broken down to release energy which is used to combine hydrogen (from the light reactions) with carbon dioxide to produce sugar. The reactions of carbon fixation are controlled by specific enzymes.
Explanation:
Answer:
Fertilization Follows. During the spring of the female cone's second year, the male and female gametes are ready. The pollen grows a pollen tube, which enters a little hole in the ovule's skin near its basal end, called the micropyle. The tube enters the ovule, and the sperm goes down the tube and into the ovule.
Answer:
Examples of cells that are produced through mitosis include cells in the human body for the skin, blood, and muscles.
Explanation:
In this case cells go through different phases called the cell cycle. The "normal" state of a cell is called the "interphase". The genetic material is duplicated during the interphase stage of the cell.
This condition is known as a super oxide in which mutated enzyme extremely functional because it helps in production of cells .
when unstable molecules that contains oxygen and that easily react with other molecules in the cells. a build up of reactive oxygen species and cells causes damage of DNA ,RNA & protein ,which cause cell death.
super oxide refers various toxic oxygen containing free radicals such as monovalant anion O2 (negative) or that compound containing potassium super oxide KO2. reactive oxygen can cause damage to the basic building block of the cell. DNA damage can occur in the form of double stranded breaks as a result of reactive oxygen induced conversion of guanine to 8-oxo guanine.
