If the tree is 30 m around, then shouldn't we take the lengths of the arms and divide it into the perimeter of the tree? So what we do is take 30/1.3 = about 23. So it would take about 23 children to stretch their arms around the tree.
E-coli bacteria which most useful in the routine monitoring of microbial pollution are gram negative rods and this is common indicator organism of water contamination.
It is important to identify enteric bacteria which is one of the major causes of diarrhea disease is bacteria and that detection of pathogenic bacteria is a global key to the prevention and identification of food borne diseases and enteric infections like diarrhea.
The extent of water contamination can be measured using these indicator organisms. This fecal coli-form group has been used as the most common indicator of general wastewater contamination because they are abundant and easy to identify.

<span>Moving to the sun. Even trees that grow to the sunlight, phototropism, take advantage of movement. Without it, any time your "Home" becomes dark, you die.</span>
Explanation:
Lysosomes are to damaged organelles, as garbage collectors are to garbage.
1.
where in a population:
p - the frequency of the <em>A</em> allele
q - the frequency of the <em>a</em> allele
- the frequency of the <em>AA</em> homozygous genotype
- the frequency of the <em>aa</em> homozygous genotype
2pq - the frequency of the <em>Aa</em> heterozygous genotype
A population at equilibrium will have the sum of all the alleles at the locus equal to 1.
2. Conditions:
A. The breeding population must be large
B. No natural selection
C. The mating must occur randomly
D. No mutations to cause changes in allelic frequency.
E. No changes in allelic frequency due to immigration or emigration.
3. By comparing the actual genetic structure of a population with what we would expect from a Hardy-Weinberg equilibrium, we can determine how much it deviates from the baseline provided by the mathematical model. Depending on how large the deviation is, one or more of the model's assumptions are being violated. Thus, we can attempt to determine which one.
