Answer:
mg of powder 1 and 
mg of powder 2
Explanation:
Let "X" denotes weight of powder 1 added to the new mixture and "Y" denotes weight of powder 2 added to the new mixture
Total weight of vitamin B1 in the mixture is equal to 
mg
Total weight of vitamin B2 in the mixture is equal to 
mg
Equation 1
Equation 2
Let us simplify the above two equations, we will get
Substituting value of X in equation 2 we get
The trout because the trout affect the population of the frogs so their for if you lower the population of the trout it would raise the population of the frogs and visversa. <span />
A neurotransmitter is a chemical substance that is released by a nerve fiber due to the presence of nerve impulses; it transport chemical information from one nerve to the other. A receptor refers to a protein molecule that is found on the cell membranes of every cell, it functions by responding in an appropriate manner to chemical signals that are coming from outside of the cell.
The relationship between the neurotransmitter and the receptor is that the neurotransmitter molecules typically bound with the appropriate receptors and bring about the expected changes in the targeted postsynaptic cell.
The antigen concentration is not used to deduce the infection pathway because the immune system of the body might fight off the antigen. The lymphocytes, which are a part of the immune system helps in the production of the antibodies, and destroying the antigens. Therefore, the use of the antigen concentration here may result in skewed results as the antigens might get destroyed by the immune response of the body. Moreover, the response of different individuals to different concentrations of the antigens will be different.
