Answer:
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.
The correct option is MITOCHONDRIA.
Active transport is a type of transport through which materials are move in and out of the cell using the energy derived from ATP. The electron transport process is a series of biochemical reactions which result in the formation of ATP molecules inside the cell. The process usually takes place in the mitochondria of the cell.
Active transport requires energy to happen, while passive does not and "happens naturally".
Answer:
Small pebbles.
Explanation:
Sedimentary rock is formed by small sediments that, under pressure, join to form a larger rock. Things such as fossils, sand, pebbles, and shells can be found in sedimentary rock.
