a.

Summary Introduction

To design: A reflex map with feedback loops for hypercortisolism caused by an adrenal tumor.

Introduction: The main causes of hypercortisolism are an adrenal tumor, pituitary tumor, and excess secretion of cortisol.

b.

Summary Introduction

To design: A reflex map with feedback loops for hypercortisolism caused by a pituitary tumor.

Introduction: Hypercortisolism caused by a pituitary tumor is known as secondary hypercortisolism.

c.

Summary Introduction

To design: A reflex map with feedback loops for hyperthyroidism caused by a thyroid tumor.

Introduction: Hyperthyroidism refers to a condition in which an individual’s thyroid gland secretes too much thyroid hormone.

(d)

Summary Introduction

To design: A reflex map with feedback loops for hypothyroidism caused due to a pituitary problem.

Introduction: The failure of the pituitary gland to secrete TSH (thyroid stimulating hormone) causes secondary hypothyroidism.

Explain down bellow what happens to the cell in pictures not in words: Decreased pH in mitochondria Increased ATP Decreased pH in cytosol Increased hydrolysis Decreasing glycogen and triglycerides Increased MAP kinase activity Poor ion transport → For each one:→ What normally happens?→ What is wrong now?→ How does it mess up the cell?
1.) Community Diversity: The brown and orange line represent two different plant communities. a. Which color represents the community with a higher species richness? b. Which color represents the community with a higher species evenness? Relative abundance 0.1 0.04 0.001 2 4 6 8 10 12 14 16 18 20 22 24 Rank abundance c. What is the maximum value of the Simpson's diversity index (remember, Simpson's index is D = p², Simpson's diversity index is 1-D)? d. If the Simpson's diversity index equals 1, what does that mean about the number of species and their relative abundance within community being assessed?
