The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment.

Answer:

The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.

Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.

In a population of plants, the allele for long stems is completely dominant over the allele for short stems. If 35% of the popul
KatRina [158]
Assumptions:
1. Equilibrium has been reached for the allele proportions
2. Absence of <span>evolutionary influences such as </span>mate choice<span>, </span>mutation<span>, </span>selection<span>, </span>genetic drift<span>, </span>gene flow<span> and </span>meiotic drive<span>.
</span>
Defining L=long stem, l=short stem, and L is dominant over l.
f(x) = frequency of allele x  (expressed as a fraction of population)
Then the Hardy-Weinberg equilibrium law applies:
p^2+2pq+q^2=1
where 
f(LL)=p^2
f(Ll)=2pq
f(ll)=q^2

Given f(ll)=0.35=q^2, we have
q=sqrt(0.35)=0.591608
p=1-q=0.408392
=>
f(Ll)
=2pq
=2*0.408392*0.591608=0.483216
= proportion of heterozygous population

Answer: percentage of heterozygous population is 48.32%

Solnce55 [7]

Answer:

Answer - 9 : 37

Explanation:

Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene.
