Answer:
Dont leave your house because you are in quaratine and need to protect other people's lives
Living things need water in their cells. Water is the universal solvent - most of the chemicals a cell needs is dissolved and transported in water. Water is an environment where chemical reactions can occur and water is needed in many of those reactions - like the hydrolysis reaction (needed in the break down of food molecules). If a cell becomes dehydrated chemical reactions slow down. Chemical balance of the cell is changed as waste materials are not removed fast enough, food is not broken down, etc. Water also helps regulate the heat that can build up in a cell during chemical reactions. A dehydrated cell = increase in cell temp. Water content of a cell also affects the pH of a cell environment. Certain reactions occur better at certain pH. Homeostasis is maintaining a balance with the the environment. Without water the balance is upset.
Answer:
Mary's target heart rate is 103 beats per minute (bpm).
Explanation:
The maximum heart rate (MHR) is the rate at which the human heart of a given person reaches the highest demands. At rest, the heart rate is about 60 to 80 beats per minute.
MHR = 220 - age
So, for Mary: MHR = 220 - 14 = 206 beats per minute (bpm)
Now we can calculate Mary's target heart rate:
Target heart rate = MHR * 50% = 206 * 0.5 = 103 beats per minute (bpm)
Hope this helped!
Viral, bacterial, fungal, communicable? I know three not sure on the fourth one sorry
Answer:
The independent variable is <u>sports drink</u> and the dependent variable is <u>amount of energy</u>.
Explanation:
In regression analysis there are two types of variables.
One is the dependent variable and the other is the independent variable.
A dependent variable is the variables under study. That is the variables that is being observed for any changes when the factors affecting the dependent variable is changes.
An independent variable is the variables that is changed to determine the changes in the dependent variables. There can be more than 1 independent variable in a regression analysis.
In this case an experiment is conducted to determine the affect of sports drink on the energy of the players.
The experiment consisted of giving some players water and some sports drink. Then the players were asked to watch a basketball game on TV for 30 minutes. Then they were asked to perform some physical tasks. The efficiency of the players were then observed.
In this case the dependent variable is the energy of the players and the independent variable is the drink they had, either water or sports drink.
