Answer: we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can!
I don't get your question, this can be helpful though
To explore the Hardy-Weinberg equation, we can examine a simple genetic locus at which there are two alleles, A and a. The Hardy-Weinberg equation is expressed as: p² + 2pq + q² = 1. where p is the frequency of the "A" allele and q is the frequency of the "a" allele in the population.
Goodluck
1) There are three clusters of leaves
2) the longest leaf measures x cm
3) the shortest leaf measures y cm
4) the plant weighs Z grams
5) the widest leaf measures w cm
Isotonic solutions affect cell size because since the outside of the cell and inside of the cell has equal amounts of salt, it is in a state of balance. The cell is not shrinking or swelling.
<span>Natural selection is likely when there are stronger selection pressures. For example, a perpetual selection pressure is the fact that organisms have to compete for food and resources, meaning the best adapted ones survive. However, a stronger selection pressure may cause natural selection to occur more obviously. An example of this is when the number of white peppered moths decreased during industrialization in England due to the soot collecting on the trees. The change in population was very fast and obvious.</span>
