Lab Instructions Scientific Reasoning ACT I Mission Memo Background The situation with the astelars calls for immediate action. Because the eggs were laid much later than expected, the nests will reach unusually high temperatures before the offspring hatch and enter the sea. Such temperatures could kill a developing astelar. If the offspring do not survive, an entire generation of these endangered creatures will be lost. The astelars need your help. While I focus my processors on running the Int...

Scientific Reasoning Module - Act III Final Assignment Background A population is a group of organisms of the same species that live in a particular geographic location. For example, people living in the city of Phoenix are considered a population of humans. Biologists estimate the number of organisms in a population (population size) to know whether a species has become too rare or too abundant. Knowing a population's size also enables biologists to manage the resources needed to susta...

What is the activation energy? - correct answer The energy required to convert a substrate to a product How do enzymes catalyze reactions? - correct answer By forming a substrate-enzyme complex. The enzyme br...

Greetings Fellow Explorer: The temperature of Phygaris continues to rise with the passing of the season. The baby astelars are now experiencing higher temperatures than they would in a typical breeding season. Trapped in their eggs, they have no way to avoid the rising temperatures. We can choose to do nothing and hope they survive. Alternatively, we can intervene by moving the eggs to a cooler beach. However, a decision of this magnitude should not be made lightly; we must use evidence to choos...

Bio 181 Lab Final Exam – Questions With Solutions

How does substrate/enzyme concentration affect enzymatic activity? - ️️If there is too much substrate compared to the enzyme, enzymatic activity will plateau Increasing the amount of enzymes will increase the rate of enzymatic activity How do enzymes catalyze reactions? - ️️By forming a substrate-enzyme complex. The enzyme brings the substrates together and put stress to break the bonds. Enzymes create a micro-environment or break bonds What is a catalyst? - ️️A substance that ...

Lab Instructions: Cell Biology Act II Mission Memo Greetings Fellow Explorer: What an incredible medical discovery we have made together! A contagious cancer is one of the rarest diseases throughout the galaxy. If left untreated, the cancer will not only spread from the lungs to other organs, but will spread from sick gliders to healthy gliders. Fortunately, we have collected data needed to determine how the tumor cells differ from healthy cells. The elevated concentration of Growth Factor...
