1.what have scientist learned from studying the skin of an urodele (Notophthalmus) at different stages in its life cycle?
Homework Answers
There are numerous scientist who have conducte studies on various aspects of Notophthalmus Scientist such as.Brodie, Hamilton, Hurlbert, Webster and many others have contributed regarding the skin of newts.
The skin of notophthalmus contain tetrodotoxin which is a neurotoxin. This toxin concentrated on the dorsal surface.This toxicity on their skin make them unpalatable to many species such as mamals, fish, reptiles and amphibians.Many animals avoid the newts because of the effectiveness of their skin toxins. The bright red colour of the newts is aposematic i.e warning off potential predators. The cryptic green-brown coloration help them to avoid predation. The subspecies of newts with bright coloration maintain a diurnal activity. Thus skin coloration of the newts contribute to a effective anti-predator mechanism.

Question 1. You are a cancer researcher studying skin cancer cells that have become metastatic (ie. they've migrated from the site of the original tumor to establish new secondary tumors). You analyze skin samples from an unaffected patient and from one with the metastatic cancer. After a series of detergent solubilization and centrifugation steps, you separate pellet samples from each tissue type by gel electrophoresis and find the following results: skin normal cancer tissue tissue 250 Da 120kDa 75kDa- 60kDa...

You are a scientist studying DNA replication. You have the ability to introduce temperature-sensitive mutations into the bacteria that you are studying (temperature-sensitive mutations work normally at one temperature, but when you raise the temperature a little, the mutation exerts its effect. This allows you to grow colonies with mutations that would otherwise be lethal. The fact that these mutations are temperature sensitive has nothing to do with the problem, other than to make it accurate to how these would...

Imagine the scenario: You are a famous scientist who has been studying blood parasites across the globe. You have just returned from the Amazon rainforest where you have collected 12 blood samples from different monkeys and also one human sample from a Brazilian volunteer. You want to investigate what type of parasite do monkeys have, and whether it has originated from humans? You decide to sequence one of the ribosomal RNA genes, the 18S rRNA. Why did you choose this...
