Green plants are considered producers because they directly absorb sunlight to make energy :)
To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.
If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.
p +q=1
0,3 +q=1
q= 1-0,3
q= 0,7
Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.
0,09 + 2pq +0.49= 1
2pq +0,58= 1
2pq= 1-0.58
2pq=0,42
The freqency of the heterozygotes in this population is 0.42
Answer:
Scientists define density as the mass of a substance per unit volume. The word “per”
signals that thinking about density requires thinking about a relationship. It is the relation
between the mass (or weight) of one unit of a material and the volume of that one unit.
Density cannot be directly perceived or measured. It must be inferred from the
relationship of the mass and volume. However, it can be determined by calculation
which is how many schools teach it. To calculate density, you first measure the weight
and volume of an object precisely, then you divide the mass by the volume (i.e. d=m/v,
density equals mass divided by volume). So for example, the density of water is 1 gram
per cubic centimeter because a volume of 1 cubic centimeter of water has a mass of 1
gram. A substance which has a mass of greater than one gram per cubic centimeter
has a density greater than 1.0 gram per cubic centimeter; a substance which has a
mass of less than one gram per cubic centimeter has a density of less than 1.0 gram
per cubic centimeter.
