Answer:
An organism that is completely composed D amino acids cannot survive.
Explanation:
Most of amino acids in all organism are present in L conformation.As result in all organism the enzymes are specific for L amino acids but not for D amino acids.
Bacterial cell wall contain some D amino acids such as D glutamate,D alanine but not entirely composed of D amino acids.
Answer:
4.21778 J/(g*C)
Explanation:
specific heat = joules / (mass times temperature change)
949 / (9 times 25)
949 / 225 =
4.21778
Answer:
SUBSTANCES
Explanation:
According to this question, Jasmine is conducting an experiment in order to see how much temperature change occurs when three different substances are heated. Based on this experiment, the INDEPENDENT VARIABLE, which is the variable that is changed or manipulated is SUBSTANCES.
A controlled experiment is an experiment where all other variables except the INDEPENDENT VARIABLE is kept the same or unchanged. The independent variable is the only variable allowed to change, which in this case is the SUBSTANCES USED.
We see that in the left-hand side of the equation, the side of the reactants, that we have 2 moles of Na and bromine is in it's diatomic form.
Therefore, we have 2 moles of each of these elements. When we combine the sodium bromide molecule in the products, we are going to want to keep these molar amounts the same. So we are going to need to put a 2 in front of the sodium bromide in order to correctly balance this equation.
So the coefficient for sodium bromide (NaBr) in this equation is 2.
Answer:
O-18 is used as a tracer in many hydrologic studies. It is most often used as a component in a mixing-model and hydrograph separation, as O-18 acts conservatively and is applied naturally and uniformly over broad areas. O-18 can be used when different sources (old water/new water) have different isotopic values.
