Answer:
C
Explanation:
A system is at equilibrium when the rates of opposing reactions are equal.
Answer A does not show the rate of reactions, it only shows concentrations of reactants.
Answer B only shows constants, it does not show rates of reactions.
Answer:
5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)
6.) Frequency of R: 0.5
7.)Frequency of R: 0.5
8.)Frequency of R: 0.375
Explanation:
5.) If R and B code for the different forms of the same protein then they are only a few possible out comes
6.) First calculate the total alleles in population
allele R= 40
Allele B=40
total allele = R+B= 40+40
=80
Now to find allele R frequency is:
(Total R alleles) / (Total allele in pop)
40/80=
0.5
7.)Calculate the total alleles
Alleles from for R
RR= 10
R=10x 2= 20
Multiply the value by 2 because there are 2 R alleles present in
RB=20
R=20
Number doesn't change there is only 1 R allele
Total R=20+20
=40
Alleles For B
BB=10
B=10×2
=20
Same thing here, two B alleles together so multiple by 2
RB=20
B=20
Total B= 20+20
=40
Total alleles in pop add
40+40
=80
Frequency of R
Total of R/Total Alleles
=40/80
=0.5
8.)Repeat the same thing in 7 but use different numbers
RR=10
R=10x2
=20
RB=10
R=10
Total R= 20+10
=30
Answer:
a. Mitosis results in two exact copies of parent cell's genetic information.
They feed on dead, decaying, organic matter.
Answer:
Sadie's continue use of marijuana will lead to her brain's reduction of the neurotransmitter anandamide which will require her to need more of the marijuana to achieve its effects.
Explanation:
The active ingredient of marijuana is tetrahydrocannabinol (THC)which is responsible for causing change in the brain.
This activates specific receptors called cannabinoid receptor.This receptors are found in limbic and cerebral cortex region and cerebellum.
As these receptors are located in the brain, the effect of these receptors are also wide spread.In healthy brain, these receptors are activated by a neurotransmitter called as anandamide that have pain relieving effect and also play important function in brain.When THC activates these receptors,causes interference of the normal function.
marijuana also boost another type of neurotransmitter called dopamine after taking the drug.
