It is a force resulting from the redistribution of energy contained by electrons, which tends to bind atoms together to form different types of molecules

Explanation:
Following the Hardy-Weinberg equilibrium theory, the frequency of the heter0zyg0us genotype is 2pq. In the exposed example, 2pq = 0.48.
<h3>
Hardy-Winberg equilibrium</h3>
The Hardy-Weinberg equilibrium theory states that the allelic frequencies in a locus are represented as p and q.
Assuming a diallelic gene,
→ The allelic frequencies are
- p is the frequency of the dominant allele,
- q is the frequency of the recessive allele.
→ The genotypic frequencies after one generation are
- p² (H0m0zyg0us dominant genotypic frequency),
- 2pq (Heter0zyg0us genotypic frequency),
- q² (H0m0zyg0us recessive genotypic frequency).
If a population is in H-W equilibrium, it gets the same allelic and genotypic frequencies generation after generation.
The addition of the allelic frequencies equals 1 ⇒ p + q = 1.
The sum of genotypic frequencies equals 1 ⇒ p² + 2pq + q² = 1
If the allele A has a frequency of 0.6, and the allele B has a frequency of 0.4, then the frequency of the heter0zyg0us genotype is
2pq = 2 x 0.6 x 0.4 =<u> 0.48</u>

Answer:
the two organelles found only in plants include chloroplasts and cell wall.
Explanation:
cell wall is the outermost boundary in most plant cells while animal cells lack it .but the cell wall of plant cells is different from that of prokaryotic cell wall, both in structure and chemical composition.CELL WALL prevents the osmotic lysis of plants and provides them a definite shape. another organelle found only in plants is the CHLOROPLAST. choloroplasts are the type of plastids which are not found in animal cells .choloroplast contain a green pigment called chlorophyll which halp in PHOTOSYNTHESIS. in adition to these plants also contain GLYOXYSOMES and a large "centeral" vacuole which is present in animal cells but it is of small size and pushed towards periphery due to nucleus.
Answer:
The change in mass of the bag was greater when it contained 20% fructooligosaccharides than when it contained 15% fructooligosaccharides because more water moved into the bag with 20% fructooligosaccharides than with 15% fructooligosaccharides.
Explanation:
Diffusion is the movement of substances from an area of high concentration to an area of comparatively lower concentration. Diffusion is said to be complete when both compartments/regions have equal concentration of the substance. The rate of diffusion increase with increase in concentration gradient, increase in temperature, and decrease in size of the diffusable substance.
In our example, the two compartments are the compartment in the diffusion beg which contains fructooligosaccharides and the compartment in the beaker which contains more water, because water (diffusing substance) moves from the beaker where it is more in concentration to the bag, where it is lesser in concentration. The bag, when it contained 15% fructooligosaccharides had relatively more water before diffusion than the bag when it contained 20% fructooligosaccharides, as a result of this, when diffusion starts, it will take a lesser volume of water to move into the 15% bag to attain equilibrium than it will take for the 20% fructooligosaccharides bag to attain equilibrium. Meaning that more water will move into the bag when it contained 20% fructooligosaccharides than 15% fructooligosaccharides making the overall volume in the bag higher.
Let me use hypothetical values; assume that before diffusion, both (15% and 20%) bags weighed 50 g of the solute (fructooligosaccharides) each, but had different concentration of the solute. Let us also assume that by the time 10g of water moves into the 15% bag, it attained equilibrium, bringing the total weight in the bag to 60g. It will take more than 10g of water to move into the 20% bag before it attains equilibrium, lets say it take 18g of water to move into the 20% bag to cause equilibrium, total weight of the 20% bag becomes (50 + 18 = 68g), hence the mass of the 20% bag will be higher than the 15% bag at equilibrium.
