<span> Embryonic stem cell research is kind of a dead area now since there is no way to control the differentiation. Most research is being done on adult stem cells to help map and control the differentiation process.
Stem-cells from aborted fetuses - The government doesn't sponsor this, if it is done it is by private companies not located in the USA. You could try researching umbilical cord stem cells to be somewhere near your topic. They come from the afterbirth of normal deliveries.
You could do a much easier report by covering cloning of mice through stem-cell technology. It is happening and helping scientists understand diseases. </span>
Answer:
The cyclist’s displacement is +5 m.
Explanation:
We have, A cyclist starts at a position of origin. He takes 3 s to move east to a position of +8 m. He then cycles west to a position of +5 m which takes an additional 2 s.
It is required to find the cyclist’s displacement. Displacement of an object is the shortest path covered by it or it is given by the difference of final to the initial position.
Finally, he cycles west to a position of +5 m. Distance between final and initial position is +5 m.
Hence, the cyclist’s displacement is +5 m.
Answer:
What will most likely happen in these lakes is that there will be a decline of several fish populations. The correct answer is A.
Explanation:
The options attached to the question are given below:
A. The decline of several fish populations
B. An increase in the number of fish.
C. An increase in the number of primary producers.
D. Increased predator- prey relationship.
The fishes, just like any other living organisms has ideal body temperature and pH at which they act best. The ideal pH for fish living in lake water is between 6 and 8. If the pH is reduced below this value then the water will become acidic and this will be toxic for the fish population living in the lakes. Therefore, those fish that can not cope will die and there will be a decrease in the fish populations.
Pinworms belong to the group of worms called the Nematodes which is the answer. Pinworms are intestinal roundworms living in the intestinal tract of animals and human. There are 4 types of pinworms and one of it is Enterobius vermicularis which then infects the humans.
