Competition
- when space is full pack organisms compete for resources and the sooner the
resources are gone. Predation - organisms feed on and kill animals lowering
their population growth and the prey population growth, same as herbivore and
human prey. Disease - again feeds on hosts. Stress from overcrowding - females
could kill offspring. Hurricanes (density-independent limiting factors).
Contour plowing, the contour lines of the terrain are being traced, and curves are considered the contour lines in this instance. Contour plowing is always done parallel.
Answer:
1. Allele frequency of b = 0.09 (or 9%)
2. Allele frequency of B = 0.91 (0.91%)
3. Genotype frequency of BB = 0.8281 (or 82.81%)
4. Genotype frequency of Bb = 0.1638 (or 16.38%)
Explanation:
Given that:
p = the frequency of the dominant allele (represented here by B) = 0.91
q = the frequency of the recessive allele (represented here by b) = 0.09
For a population in genetic equilibrium:
p + q = 1.0 (The sum of the frequencies of both alleles is 100%.)
(p + q)^2 = 1
Therefore:
p^2 + 2pq + q^2 = 1
in which:
p^2 = frequency of BB (homozygous dominant)
2pq = frequency of Bb (heterozygous)
q^2 = frequency of bb (homozygous recessive)
p^2 = 0.91^2 = 0.8281
2pq = 2(0.91)(0.9) = 0.1638
Whether or not the article describes persenal experience is the major determining factor in this question. If the article tells the story of another, it is secondary, if the article was written by someone who is recounting on their experience, it is first peron. Hope this is clear and understandable.
Answer:
It it not, In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
