Answer:
3) 0.75m/s
Explanation:
The wavelength of a wave is calculated using the formula;
λ = v/f
Where!
λ = wavelength of wave (m)
v = velocity or speed (m/s)
f = frequency of wave (Hz)
According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.
Using λ = v/f
v = λ × f
v = 0.25 × 3
v = 0.75m/s.
 
        
             
        
        
        
both alleles in the heterozygous
genotype are exhibit in the phenotypes.  Allele
is completely dominant over the other, and  it is the phenotype is a blend of the two
homozygous phenotypes, there are more than two forms of the same gene, and
there maybe one more superior form and several different phenotypes
 
        
             
        
        
        
Answer:
A)Fixation. Nitrogen in its gaseous form (N2) can't be used by most living things
B) it can not be used because it most be converted or, ’fixed’  to a more useable form. To do this it goes through a process called fixation.fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) in a given population to a situation where only one of the alleles remains. 
C) This form can be made more usable if it’s converted. It has to go through the process of fixation so the gene pool changes.

Answer:
The nutrient cycle describes the use, movement, and recycling of nutrients in the environment. Valuable elements such as carbon, oxygen, hydrogen, phosphorus, and nitrogen are essential to life and must be recycled in order for organisms to exist.
