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.
Well because death by starvation would be far more agonizing than death by predators. Starving to death would last longer and the death would be more excruciating.
The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. ... To form a covalent bond, one electron from the halogen and one electron from another atom form a shared pair.
They have both plant and animal characteristics. All live in water, and moves by means of a flagellum. This is an animal characteristic. Most have chloroplasts, which are characteristic of Algae and Plants
