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.
Answer:
in dogs there is a hereditary type of deafness caused by a recessive gene. Two dogs who carry the gene for deafness but have normal hearing are mated. what are the possible genotypes and phenotypes of their offspring and the percent of chance for each?
Dd x Dd = DD, Dd, Dd, and dd
3:1 genotype
phenotype shows that there is 3 dominant gene for normal hearing while 1 for deafness (two homozygous where 1 is dominant and the other is recessive) and (two heterozygous with normal hearing dominant over deafness recessive)
Explanation:
Answer:
They are quite vicious when people or predators get too close to their territories
Explanation:
The answer is B. 25°C.
A temperature of 25°C can be considered as a room temperature. It is an optimal temperature for the most living beings which cell potential is considered as standard. It is known that at 100°C water boils, so this temperature cannot be standard, cells will degrade at this temperature. Similarly 0°C and –273°C are too cold, water of the cells will freeze, cells will freeze, and cell potential will not be optimal.
