Overview of types of immune responses. Difference between innate and adaptive immunity. Differences between humoral adaptive immunity and cell-mediated adaptive immunity.

Outcomes

In this course you will learn how to:

1. Use exponential notation and exponential identities.
2. Multiply exponents.
3. Divide exponents.
4. Raise a power to a power.
5. Change fractional exponents to radical form.
6. Simplify surds.

In this video we’re going to discover how to factorise quadratics that don’t have 1 as the coefficient of the x-squared term. These are called non-monic quadratics. We can do it by trial and error and just spotting the factors, but this takes a lot of trial an error. Luckily there is a different method we can use instead, which we will looks at in this video.

Three activities which illustrate the law of exponents.

This is a simple video which describes how indices problems are solved using simplified laws.

Online problems where the student is required to simplify the expression using the product property of exponents.

An activity explaining the properties of exponents.

Outcomes

In this course you will learn how to:

1. Solve quadratic equations by factorisation.
2. Solve quadratic equations by using the quadratic formula.
3. Solve simultaneous equations involving quadratic equations
4. Solve word problems involving quadratic equations.

Role of phagocytes in innate or nonspecific immunity. Neutrophils, macrophages, and dendritic cells.

By the end of this unit you will be able to:

• Solve equations with a single variable which are called linear equations
• Solve equations with a single variable that is squared (quadratic equations) by factorisation.
