Neuron Communication

Neuron Structure: There are three main types of neutrons, each with similar but slightly  different structures. These neutron types include Interneurons, sensory neurons, and motor neurons, each shown below. These three neuron diagrams each consist of an axon, dendrites, a cell body, and a nucleus (real neurons also possess a myelin sheath as well as […]

Week 14- Equivalent Rational Expressions

This week we began chapter 7, the first lesson of chapter 7 was on equivalent rational expressions for example are all equivalent rational expressions, also known as fractions. The definition of a rational number is “the quotient of two integers” whereas a rational expression can be defined as “the quotient of two polynomials”. Since these […]

Week 13- Reciprocal Functions

In this lesson (8.3,4,5) we started graphing and understanding reciprocal functions of linear and quadratic equations. Reciprocal linear functions: Reciprocals of linear functions will always create a “2 part graph” this is referred to as a hyperbola, a hyperbola of a linear graph will always have two “swooping L” shaped lines exactly opposite each other […]

Week 5 – Solving Radical Equations

The solving of radical equations can be difficult to maneuver at times and understanding what each consecutive step may potentially look like can sometimes prove more challenging. The main ideas to remember when working to solve a radical equation are as follows; what you do to one side of the equation you must do to […]

Agar Cube Lab

Concluding questions: 1.In terms of maximizing diffusion, what was the most effective size cube that you tested? The cube that we found was most efficient at absorbing/diffusing was our smallest cube approximately 2.Why was that size most effective at maximizing diffusion? What are the important factors that affect how materials diffuse into cells or tissues? The […]

DNA structure model (A)

1. Explain the structure of DNA- use the terms nucleotides, anti-parallel strands, and complimentary base pairing. DNA (or deoxyribonucleic acid) is essentially a large polymer made up of several nucleotide monomers. The polymer itself consists of two sugar-phosphate “backbones” that operate as anti parallel strands (one strand is inverted to the other strand). DNA is […]

Translation- protein synthesis (D)

1. Describe the process of translation; initiation, elongation, and termination. Initation begins when the mRNA binds to a small ribosome subunit, the two ribosome subunits bond together and search for the word “AUG” in order to start the second process, elongation. Elongation occurs while the ribosome holds onto the mRNA, the tRNA then collect amino […]

DNA replication model (B)

1. When does DNA replication occur? DNA replication will occur just prior to cell division. DNA will undergo its semi-conservative process and will begin its three stages of replication. 2. Name and describe the 3 steps involved in DNA replication. Why does the process occur differently in the “leading” and “lagging” strands? The three steps involved […]
