Science experiments can be like “measuring how heart rate is effected by music “
Answer:
because the body requires a higher supply of oxygen
Explanation:
Cellular respiration can be divided into two different metabolic processes: aerobic respiration which needs oxygen (O2) and anaerobic respiration (without O2). The aerobic cellular respiration is produced when glucose molecules react with O2 in order to form ATP, the energy currency of the cell. Aerobic cellular respiration is the main source for generating ATP. During exercise, the requirement of O2 will be higher because the cellular respiration rate is increased in order to produce more energy (ATP). In consequence, during physical activities, it is required have to breathe faster to supply this O2, which enters into the lungs to be transported to all the cells through blood circulation.
Answer:
The correct answer is: E) both B and C.
Explanation:
- Bacteria and Archaea forms two distinct and different Domains in the Taxonomic classification system.
- Nuclear envelope that surrounds and protects the genetic material by forming the Nucleus is absent in both Archaea and Bacteria. Both of them possess a region called the Nucleoid where their genetic material is located.
- Plasma membrane that surrounds the cell and maintains integrity of the cell structure is present in both Bacteria and Archaea. Although the composition of lipid in the plasma membrane is different in each.
- However, they vary in their cell wall composition. The cell wall of the bacteria is rich in a compound called peptidoglycan while the cell wall of archaea lacks peptidoglycan and is rich in polysaccharides and glycoproteins.
