Answer:
nucleus
Explanation:
Since the nucleus of the cell contains DNA (genetic material), she must focus on the nucleus.
Answer:
DISADVANTAGES
Embryonic stem cells can have high rejection rates
Adult stem cells have a determined cell type
Obtaining any form of stem cell is a difficult process
Stem cell treatments are an unproven commodity
Stem cell research is a costly process.
ADVANTAGES
can help enhance the growth of new healthy skin tissue, enhance collagen production, stimulate hair development after incisions or loss, and help substitute scar tissue with newly developed healthy tissue.
Answer:
According to the previous observational study it is possible to notice that thinning determined in great way the rate of trees that survived the fire.
Explanation:
In general the trees that had been previously cut, were the ones that presented more resistance to the fire, while the trees that had not been thinned were the ones that were severely affected in the spreading conflagration. Reason why in comparison of these two samples, it would be possible to conclude that previously cutting down trees can survive better to the spreading fire.
Answer: Van der Waals forces
Explanation:
Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.
The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.
Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.
Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
It’s because 15ml was just under the range and 50ml is just over it. 30 is a happy middle.
