Evidence of evolution suggests life may change. Outline the impact on the evolution of plants and animals of: Changes in physical conditions in the environment - Some animals do not survive changes in the environment and become extinct or endangered. Changes in physical conditions such as climate ad exposure to fire has led to changes in flora (Australia drifts north) Changed in chemical conditions in the environment - pH of environment can be critical to functioning of enzymes and metabolism

A force can do one of four things to an object: 1. Make it speed up - accelerate. 2. Make it slow down - decelerate. 3. Change its direction. 4. Change its shape. If something is doing one of these four things there must be net force acting upon it. Newton’s First Law ’Every body continues in a state of rest or uniform motion unless acted upon by an external force.’ Something without net force acting on it will either stay still or move at a constant speed in a straight line until

3.1.1 Identify that matter is made of particles that are continuously moving and interacting The particle theory states that all matter is made up of tiny particles and they are constantly moving/continual state of motion. 1.1.2 Identify the difference between elements‚ compounds and mixtures in terms of particle theory Elements are simplest form substance meaning cannot be decomposed further physically or chemically. They are made up of same type of atoms only e.g. helium‚ oxygen. Compounds

During the fall of my 11th year‚ I was adopted by my second family along with little Leo. They were horrible to us‚ out of the 6 I was the eldest. All of us crammed together‚ Them barely having enough for all of us. Well‚ that’s a lie‚ They had enough‚ just didn’t want to share. They‚ I could never bring myself to refer to Them as anything other than They‚ didn’t care about us. All They cared about was the paycheck. I took on the role of the mother. I made sure that everyone got enough food to last

1) How do you calculate average speed? Average speed = Distance Time For example‚ if you have a car that has travelled 50km in 20 minutes the average speed would be 1km/2.5min. 2) A student measures the distance their rocket travels and has also recorded the length of flight. He works out the speed with the two values measured‚ and exclaims “I’ve worked out its top speed!” Discuss this statement. This is a false statement‚ the student has not worked out the rockets top speed‚ they have

Environmental Change Evolution is the process of change that occurs in living organisms over many generations. It is the result of natural selection by the environment of favourable variations in the organisms. Changes in the environment of living organisms can lead to the evolution of plant and animal species. These environmental changes in condition may be physical- temperature‚ rainfall‚ sea level and landforms e.g. Peppered Moths chemical- water salinity‚ acidity‚ use of pesticides‚ oxygen
