a) Increased heart rate, increased blood pressure, increased respiration rate.
Explanation:
When a person do any physical activity like running, jogging, cycling, swimming and stair climbing, the heart rate, blood pressure and respiration rate of a person are increased because due to physical activity, the body needs more and quick oxygen and energy. This oxygen is provided by heart through pumping of blood and energy is released due to the breakdown of glucose molecules that occurs in mitochondria of the cell in the process of respiration. For providing oxygen and energy quickly, blood pressure of the body is increased.
Answer:
Ribosomes
Explanation:
This is the organelle for regulating protein synthesis in cells.It is made up of the small and big submits. These sub units collectively ensure the process of translation of protein my ensuing the correct synchronisation of condoms not he smaller nit of ribosomes with the anti codons on the tRNA with the to give a designated protein.
Therefore if there is mutation -deletion or substitution in the codons and anti codons,.this may affect bring frame shift which affects the protein translated leading to wrong protein formation.
Mitochondria is the organelle that gives the sperm power to swim.Therefore the protein that codes for mitochondrial is faulty and this affects the the tail from swimming properly.since ribosomes is the source of protein this is the correct answer
