Answer:
Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.
Explanation:
Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
<u>Aerobic Respiration</u>
- Occurs in the presence of free oxygen.
- Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
- Respiration occurs in the mitochondria.
- Takes place in two steps or stages: Krebs cycle and electron transporter chain.
- Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.
<u>Anaerobic Respiration </u>
- Occurs in the absence of free oxygen
- Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.
- There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.
- Lactic fermentation produces lactic acid and 2 ATP
- Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂
- The whole anaerobic process occurs outside the mitochondria.
Answer: option b - 55
Explanation:
Menopause signifies the time in a woman's life when menstruation ends, usually BETWEEN age 45 - 55.
And because of the crucial role played by Oestrogen in menstruation, its LOSS increases the RISK of HEART DISEASE seen in women AFTER MENOPAUSE .
Faster growing population
Answer:
the billions of cells that originate from one parent cell
Explanation:
Answer:
<em>In a scientific investigation the term quantitative data refers to numbers that are usually followed by a unit.</em>
Explanation:
A scientific investigation can be described as an investigation which is made through the scientific method of research. A scientific question is often tried to be answered through valid experiments by this method. The experiments performed can either be quantitative or qualitative. Quantitative data is the data which is taken through mathematical or statistical methods and has a well-defined unit in which the measurements or numbers are being taken.
