Answer: Hi there, I'm so sorry no one answer your question here is what I got
The nervous system makes you thirsty. The integumentary system makes you sweat.
The hypothalamus is part of the nervous system and controls vegetative functions, such as hunger, thirst and body temperature. When you run a race, your body starts to lose fluids due to sweat. At that moment the nervous system (through the hypothalamus) trying to maintain homeostasis in your body signals that you are thirsty.
As already mentioned above, when you participate in a race you start to sweat. This is a reaction of the integumentary system, through the skin, releasing fluids to regulate your body temperature.
Explanation:
B. Mitochondria
The process of cellular respiration is essentially when oxygen and carbon transfuse themselves together to create carb on dioxide, which in turns creates energy.
The entire process is formed in the powerhouse of the cell, or in other words, the mitochondria.
A part of this question that may have been confusing is the answer, "lungs". Since respiration is correlated to the lungs, you may have been confused. However, this is a process that occurs within your cells, so on a small scale than your entire body.
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Answer:
When CO2 is breathed into the lungs, it dissolves in the water there, diffuses across the alveolar-capillary membrane, and enters the bloodstream. As it combines with water, it forms carbonic acid, making the blood acidic. So CO2 in the bloodstream lowers the blood pH.
