Las especies invasoras son animales, plantas u otros organismos que se desarrollan fuera de su área de distribución natural, en hábitats que no le son propios o con una abundancia inusual, produciendo alteraciones en la riqueza y diversidad de los ecosistemas. Cuando son transportados e introducidos por el ser humano en lugares fuera de su área de distribución natural, consiguiendo establecerse y dispersarse en la nueva región se les denomina especies exóticas invasoras resultando normalmente muy dañinas

Hello, Leah082656. There are many heated arguments over discussing stem cell research because of these two moral principals: the duty to prevent or alleviate suffering and the duty to respect the value of human life. In order to get embryonic stem cells, the embryo has to be destroyed. Although this is a huge controversial problem, by researching this could actually save and treat many other people. Some people are for it because it saves multiple people in the process, and some do not like this because it is killing an embryo. Whatever your stance is on this debate, these are the two sides that people debate over. I hope I helped!! Have a great day. :)
Answer: A
The cells would lose water and shrink. In a hypertonic solution, the
concentration of solute is higher than water in a cell. With this, there is a
net movement of water from inside to outside initiating water to lose from the
cytoplasm and vacuole causing the cell to shrink due to osmosis and achieve
equilibrium.
This process is applied in food preservation where microbial cells will
be dehydrated in a hypertonic environment, making them malfunction and preventing
them to cause food spoilage.
