It says if you scratch scabies they will get worse sort of like chicken pox.

Disease Talk with Survey of Human Body Systems Students

The integumentary system is the largest organ in the body, our outermost covering, and our first line of defense against foreign material that might enter our body. Use the website I paste below to learn about the three skin diseases listed. Choose at least one other disease to learn about. View at least one other website for each of the diseases to see pictures of what the diseased skin looks like and to gain additional information. Post a comment after you have completed your research. Be sure to include personal knowledge/experiences with the diseases. For example, you may have always heard how one of these spreads; you may have seen someone's skin you has had one of these diseases/disorders; etc. Describe your reaction to your new knowledge and your prior knowledge with these disorders/diseases. Remember not to mention names of people or refer specific people in your posts. Reply to at least one other person's post by asking them a question or commenting on their post.

Which threats to biodiversity caused several mammal extinctions?

Hello, my biology students. We have been studying A LOT about biodiversity. The most recent subject we discussed was "threats to biodiversity." Remember, each group discussed a threat within your group and then we discussed all of them as a class. They are:
1) Habitat Loss 5) Habitat Degradation
2) Water Pollution 6) Habitat Fragmentation
3) Land Pollution 7) Edge Effect
4) Exotic Species
Your task:
A) Research the extinct animal that I assigned you and figure out the reason for its extinction.
B) See if it fits into one of the threats to biodiversity that we mentioned.
C) Reply to my blog and make a short description of your animal and its name.
D) Describe how its extinction occurred and which threat led to the animal's demise.
E) Make two additional posts as replies to other students' posts.
