Developmental biology THEMES including concentration gradients, time, location/induction, inhibition of an inhibition, negative and positive feedback loops, etc. just to name a few. Pick ONE themes and using three different developmental stages/processes provide three detailed examples of this ONE theme (if possible to do these three stages/processes in one model organism please do so, but if choose to use more than one organism for your examples that is fine).

Expert Solution

I have choosen negative and positive feedback mechanism, concentration gradient, location.

Now i am providing details about one theme using 3 stages:-

Negative and positive feedback mechanisms used to maintain homeostasis. Describe one negative and one positive feedback regulation (8pts). For each negative and positive feedback: What is the variable? (0.5pt) What is the normal range? (0.5 pt) Which conditions may change the variable? (0.5 pt) How the changes to be detected? (1 pt) What is/are the responses(s)? (1pt) What is the final effect? (0.5 pt)

Question 1 Positive feedback differs from negative feedback because ________. positive feedback is generally beneficial while negative feedback is typically harmful positive feedback tends to enhance the triggering stimulus while negative feedback tends to return the body to a homeostatic balance or "ideal" level positive feedback is critical to health while negative feedback serves only to alert us to potential health threats positive feedback provides moment-to-moment wellbeing while negative feedback causes a cascade effect 2 points Question 2 A substance...
