Answer: Oogenesis
Explanation:
Oogenesis is a process in female reproductive system in which a matured ovum is formed from egg cell.
In human reproductive system one mature ovum is produced from four haploid cells during meiosis. This ovum is very large and it unite with the sperm to produce zygote.
There are three stages of Oogenesis, the multiplication phase,the growth phase and maturation phase.
In the multiplication phase, the germinal cells divide to form oogonia. The oogonia multiply and form oocytes. The oocytes pass through the growth phase and mature to form ovum.
They all breathe oxygen
Their body is full of water
Hope this helped :D
Osmosis of Water Across the Membrane. Osmosis is the tendency for water molecules to move from where there is a higher concentration to where there is a lower one. ... The cell membrane helps to regulate and slow down the flow of water into the cell. This is yet another way that the cell membrane helps maintain homeostasis
Answer: frameshift mutation
Explanation: A frameshift mutation is a particular type of mutation that involves either insertion or deletion of extra bases of DNA. Now, what's important here is the number three. The number of bases that are either added or subtracted can't be divisible by three.
Answer:
c. Glycolysis evolved in an oxygen-rich environment.
Explanation:
Glycolysis is the pathway that breaks down glucose into two molecules of pyruvate. It is a common pathway that is performed by both aerobic and anaerobic organisms. In aerobic organisms, glycolysis is followed by Kreb's cycle and electron transport chain. In anaerobic organisms, alcohol or lactic acid fermentation regenerate the NAD+ which is required to sustain glycolysis.
Therefore, glycolysis is independent of oxygen availability and can be performed under both aerobic and anaerobic conditions. This means that the pathway of glycolysis evolved under anaerobic conditions.
