CLoud b would release rain because it is the first one to release heat.
Answer:
The answer is dopamine, tegmental
Explanation:
The most effective sites for self- stimulation for reward are along the trajectory of the Dopamine axons airising in the ventral Tegmental area and projecting to the forbiden.
It is important because you need vitamins and minerals from them e.g. Scurvy no vitamin c
The correct answer for this question is 'Mouth, Stomach, Small Intestine'.
what is Digestion?
Digestion is the process of breakdown of large insoluble food molecules into small water soluble molecules for absorption is called as digestion
The digestion of Carbohydrates usually takes place in small intestine but the digestion process starts in the mouth by the help of salivary amylase present in the saliva. The complete digestion takes place in small intestine with the help of pancreatic enzymes called α-glucosidase and amylase
The protein digestion takes place in the stomach as the Ph conditions are favourable for the digestion of proteins the stomach walls release pepsin enzyme for the synthesis of proteins the protein digestion also takes place in small intestine.
Lipids are mostly digested in the small intestines by the help of bile and pancreatic lipases the lipids get broken down to fatty acids and monoglycerides for easier absorption this process of breaking down fats is called as Emulsification

#SPJ4
Answer:
Control group: volunteer stationary bike riders in a pollution-free chamber
Experimental group: volunteer stationary bike riders in a chamber filled with air pollutants common to Los Angeles
Independent variable: exposure to air pollution
Dependent variable: The heart rates (physical fitness) of the volunteer riders.
Explanation:
In a scientific experiment, data is compared between the control group and experimental group to ascertain the effect of the independent variable on the dependent variable. A control group is the group in an experiment that is not treated with the independent variable i.e. the independent variable is controlled while the experimental group is the group that is treated with an independent variable.
N.B: The independent variable is the variable controlled by the experimenter in order to influence the dependent variable (measurable outcome).
In this experiment, the independent variable is the AIR POLLUTION the volunteer riders are exposed to while the dependent variable is the PHYSICAL FITNESS/ HEART RATES of the volunteer riders, which is dependent on the exposure to air pollution (independent variable).
The control group in this experiment is the volunteer riders placed in a POLLUTION-FREE CHAMBER where the independent variable cannot influence or have any effect on the measurable variable (dependent). The experimental group is the volunteer riders placed in a CHAMBER FILLED WITH AIR POLLUTANTS. The independent variable (air pollution) has been changed in the experimental group.
