Answer:
lower activation energy
brainliest is appreciated
Explanation:
Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership.2
Answer:
a) 
b)
c) 
Explanation:
Given ,
Frequency of white flower plant (
) is 
Thus, frequency of dominant white allele (
) is equal to 
As we that, as per Hardy-Weinberg equilibrium equation
Substituting the value of in above equation, we get
a) As per Hardy-Weinberg equilibrium equation
Substituting the given and calculated values in above equation, we get -
b) The frequency (decimal form) of the dominant allele
c) number of homozygous purple flower plants
frequency of purple flower plants (
) 
Number of flowers
Answer:
Brain
Explanation:
A shock is a medical condition which is caused when the body has the less available substrates for the aerobic respiration and shift to anaerobic cellular respiration.The shock takes place in four-stage in which the second stage is the compensatory stage.
During the compensatory stage, the sympathetic nervous system gets activated to shift back the respiration from anaerobic respiration to aerobic respiration.
The sympathetic nervous system releases the epinephrine and nor-epinephrine which acts on the kidney to maintain blood pressure. During this process, the Brain is not affected by the shock condition.
Thus, Brain is correct.
B. Unbalanced because temperatures are rising
Answer: is 84.78 mm^2
Explanation:
we will first find out their areas, the area to be found is of a circle 
R^2
for the first one,
R=radius
pi=3.14
so,=3.14*(3mm*)^2
=28.26mm^2
for the second one
=3.14*(6mm*)^2
=113.04mm^2
their differences are equal to 113.04 - 28.26
=84.78 mm^2
