Some genetic mutations can be completely harmless, while others are life-altering. Mutations happen when DNA is copied incorrectly. This causes an irregularity in the DNA. Mutations are permanent changes to genetic material that can be passed on to offspring. These changes happen randomly and can occur in any type of gene. While some mutations are not harmful (hazel eyes, for example), many mutations have harmful effects on health.
You should use the same amount of beads for both chromosomes because they need to match in size.
I am assuming you are making a pair of homologous chromosomes out of pop beads, and they should have the same size because they code the same information, the only difference between them is that one comes from the mother and ther other from the father. (Homologous chromossomes have the same genes in the same loci).
Answer:
Adjacent to the yolk sac
Explanation:
Chorionic villi are microscopic and fingerlike projections found near the placenta which contain capillaries, increase surface area of blood that allow blood to flow and transfer nutrients from the mother to the fetus. The chorionic villi is adjacent to the yolk sac because it developed from the yolk sac, villi can extend and contact maternal blood vessels thereby nourishing the embryo and transfering nutrients from the mother to the fetus.
Answer:
This flaw of thinking is called the HINDSIGHT bias.
Explanation:
<em>"We don't really know the result, but we think as though we do." </em>
The Hindsight bias, <em>creeping determinism</em>, or <em>knew-it-all-along phenomenon</em>, is the <u>assumption of an individual regarding an event that have already occurred as expected, as if he knew it even before the event took place</u>. This leads to the person believing they have a high sense of certainty of what the outcome would really be, even before the culminating of the event. This usually <u>results to </u><u>overconfidence or overestimation</u><u> in recalling the sequence of events before the predicted bias</u>.
<h3>There are 3 levels of hindsight bias </h3>
- Memory distortion - unable to recall the previous judgment (<em>"I said it would happen"</em>).
- Inevitability - the event must happen even with or without the circumstances (<em>“It had to happen”</em>).
- Foreseeability - that belief and confidence wherein results of the event were already anticipated, even way before the event culmination (<em>“I knew it would happen”</em>).
Both the shrimps and the cockroaches are considered to be as scavengers at any point because they feed on dead organisms. Therefore the most accurate statement among the two organisms is "<span>Both animals are detrivores, and they fill the same niche in different environments."</span>
