The abiotic factors that play an important role in the tropical forests are the rain, to give the animals and plants the water they need to grow, the sunlight, it gives the plants and trees the energy they need to perform certain tasks like photosynthesis, which gives animals air to breathe.
Answer: ATP (adenosine tri-phosphate) supplies energy for cellular activities when one of its phosphate bonds is broken.
The answer is; D
A balanced equation is one that observes the law of thermodynamics on the conservation of matter and energy. Matter or energy cannot be created or destroyed but can only be transformed.
In this equation, therefore, the number of elements on the right side of the equation should match those of the left side. Of the choice equations, this is a balanced one; 6CO2 + 6H2O --> C6H12O6 + 6O2 and one that reflects the process of photosynthesis.
Answer:
the frequency of the resistant allele after one generation is 0.989
Explanation:
Given that :
A farmer plants Bt cotton that is genetically modified to produce its own insecticide.
Of the cotton bollworms feeding on these Bt plants, only 5% survive
i.e the survival rate s = 5% =0.05
unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide
Frequency of R allele = 0.01
In order to determine what will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton; we need to first determine the frequency of the recessive allele r.
According to Hardy-Weinberg Equilibrium ;
p+q = 1
Let p = R and q = r
R + r = 1
0.01 + r = 1
r = 1 - 0.01
r = 0.99
Now; the frequency of the resistance allele after one generation can be calculated as :

where ;
q' = R
q = r



q' = 0.989
Thus; the frequency of the resistant allele after one generation is 0.989
