Estrogen affects many parts of the body besides the uterine lining.  It is also important in secondary sex characteristics.  In addition, it increases the sense of smell and taste.

a. Based on your graph, during which part of the menstrual cycle would these senses be most intense?  How would this be an adaptation to increase the chances of conception?

Which of the following is an example of proximal stability creates distal mobility

Which of the following is an example of proximal stability creates distal mobility a decrease in hamstring mobility after performing a plank be increase hamstring mobility after stretching the Cavs see increased shoulder mobility after stretching the pectorals de increase hamstring mobility after performing a plank

Hypotheses concerning the evolution of arthropods

Insect evolution is evolving! There are two general hypotheses concerning the evolution of arthropods: the older Articulata Hypothesis and the more recent Ecdysozoa Hypothesis. Briefly, describe the morphological and molecular data that support each hypothesis. Okay, time to choose: which hypothesis is more credible, then explain why you made this choice by providing evidence to back up your claim.

0 produces leaves, branches, and flowers 0 brings gases, water, and nutrients to cells that carry out
photosynthesis

Which of the following human activities disrupt the phosphorus cycle and have negative effects on an ecosystem?

A. Soaps and laundry detergent enter the water supply.

B. Farmers use crop rotation to maintain nutrients at high levels in the soil.

C. Fossil fuels are extracted from deep in the ground, releasing nutrients stored in bedrock.

The Polymerase Chain Reaction

The Polymerase Chain Reaction (PCR) is needed before we do Gel Electrophoresis of DNA. PCR allows us to quickly amplify/copy a single segment of DNA a billion times. Then that DNA can be run on a gel. We will watch this video and answer the following questions https://youtu.be/mdB-Edy6scE

  1. What can the DNA Thermal Cycler do?
  2. What happens to the DNA at 95 degrees Celsius?
  3. What happens to the DNA at 50 degrees Celsius?
  4. What happens to the DNA at 72 degrees Celsius?
  5. What happens in cycle 2?
  6. What are the “desired fragments” that quickly become the majority of DNA in the tube?
  7. How many copies of your desired fragment are present after 4 PCR cycles?
  8. How many copies of your desired fragment are present after 5 PCR cycles?
  9. How many copies of your desired fragment after 30 PCR cycles?

 What factors play a part in the glomerular filtration rate?

What factors play a part in the glomerular filtration rate? What is the main factor that determines the rate of glomerular filtration? How is the glomerular filtration rate regulated? The glomerular capillaries are fenestrated, diameter of the efferent arteriole is smaller than the diameter of the afferent arteriole, the visceral layer of the glomerular capsule is porous. Molecular weight and electrical charge affects filtration pressure, the amount of filtrate produced by the kidneys each day, how much bowel you put out.

The allele responsible for cystic fibrosis is recessive in humans

The allele responsible for cystic fibrosis is recessive in humans. A woman with cystic fibrosis has children with a man who does not have this disorder but whose mother did. If they had two children, what would be the probability that their children have the disorder?

How did the Linnaean system of classification improve Aristotle’s system?

The system of classification developed in ancient Greece by Aristotle was used in Europe up until the early 1700s. How did the Linnaean system of classification improve Aristotle’s system?

A. The Linnaean system added more levels to the hierarchy of complexity that Aristotle developed.

B. B. The Linnaean system used genetic information to determine which organisms were the most ancient.

C. The Linnaean system organized living things based on their levels of complexity relative to each other.

D. The Linnaean system showed relationships between organisms based on observable characteristics.
