Problem:

Question 1: What matter if I increase the temperature to 95°C. So double-strand DNA denatured into two ssDNA, and then I decrease the temperature to room temperature. Are they able to reassociate after denaturation?

Question 2: Describe the stability and/or unstability of five diferent types of isotopes and their specific involvement in evolutionary insights.

Question 3: Describe evidence used by scientists to determine whether early hominins were browsers (eating shrubs primarily) or grazers (eating grasses primarily). Describe evidence used by scientists to infer that ancestors became primarily bipedal before having an enlargened brain. What factors would have likely contributed to being bipedal and what factors would havecontributed to having an enlargened brain? Indicate the time ranges for the transitions described.

Please provide discription of all the answers.
