they might conserve water
Answer:
- <em><u>color of light, then white light will produce the tallest plant."</u></em>
- Explanation:
<h2>Identify at least four controls in the experiment and give a possible example for each - Create a realistic way to test the hypothesis - Indicate a way to record data - Create a realistic conclusion based on your test</h2>
Genetic Drift is a term used to describe part of the evolutionary process. Genetic Drift is a term describing the random environmental factors such as volcanic eruptions, trees falling down, forest fires etc, that affect the gene frequency in the population of a species after the event has taken place. So, we can say that genetic drift in a population can affect the gene pool by either allowing the gene pool to increase of decrease. A typical example is that of the worldwide rhino population. The more the rhinos are poached, the smaller the genetic pool becomes. Eventually this can lead to the extinction of the species.
Answer:
Mutations are essential for evolution to occur because they increase genetic variation and the potential for individuals to differ. The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection.
Answer:
O Gln replaced by Glu or Asn
Explanation:
- Gln replaced by Glu or Asn, is a non-conservative substitution. Gln has a much shorter side chain or R-group than Glu or Asn. Additionally both Glu and Asn R-groups are polar and negatively charged while Gln is non-polar.
- In a protein, replacement with Glu or Asn would greatly destabilize the protein by introducing a charge and disrupting hydrophobic interactions formed between Gln and other non-polar residues.
- By comparing the R-groups of the residues, their length, hydrophobicity, charge and shape. One can predict if the substitution is disruptive or not, if residues are very similar then the interactions that they form are preserved. For example replacing Gln with Ala would be less disruptive.
