Answer:
Stem cells are cells in the human body that have the ability to develop into many other body cell types. Stem cells are very useful for drug development, research, they aren't likely to be rejected in transplants, and are used to repair damaged or diseased cells and tissues. However, they cannot be grown for long periods of time, there are very small numbers in each tissue and cell making them very hard to find, and for certain studies they have been shown to cause cancer. To be honest, using them in research does have its pros and cons, they are very useful and easier to use in research, plus they can help repair damaged and diseased cell tissues. But at the same time they can be difficult to use correctly and properly, it can cause serious health problems if cancer doesn't take place. I think that using them in research is okay, as long as they are used correctly and properly.
Hope this helps! :)
The bark of a tree is impervious to gases and water because bark cells are dead cells of the epidermis and compactly arranged without intercellular spaces. They contain a chemical called suberin in their walls that make them impervious to gases and water and it doesn't allow gases or water into the tree as bark cells are in the bark outer most layer of the tree.
because the total time for restoration is lengthy, peat can be considered a fossil fuel. The correct option is B.
<h3>What exactly are fossil fuels?</h3>
Fossil fuels are fuels derived from the remains of dead plants and animals that decomposed over time under intense heat and pressure.
Because their replenishment time is longer than a human lifetime, fossil fuels are non-renewable energy sources.
Some examples of fossil fuels are petroleum, coal, etc.
The missing options of the question are:
- peat is a fossil fuel because rewetting it takes only 3-5 years.
- peat is a fossil fuel because the total time for restoration is lengthy.
- peat is not a fossil fuel because it has biologic origins, making it a biofuel.
- peat is not a fossil fuel because humans can promote the replenishment of peat.
The restoration process of peat takes a long time of more than 100 years. As a result, because the total time for restoration is lengthy, peat can be considered a fossil fuel.
Thus, the correct option is B.
