What is the difference between natural variation and natural selection?

Variation is simply the differences between individuals of a species. E.g. we are all humans but there are variations which make us all different. Natural selection is the process by which the individuals best adapted to survive, breed and pass on their genes. Those not suited to an environment will eventually die out. Some variations may be advantageous therefore there may be more of those organisms around and therefore those will be most prevalent in that habitat. Some variations may be detrimental and cause those numbers to decline.

What is Q&A on Scoodle?

At Scoodle we understand that everyone learns in a different way. Some people learn through practice, using essays and notes; others prefer video lessons to watch and learn, some just need help with a specifically hard question, while some learn best 1-on-1 tutoring sessions. At Scoodle we cater for all types of learning styles and needs. From GCSE Maths video lessons to A-level English essays and specialist educators in every subject - we’ve got you covered.

Currently doing my third degree in economics

I am an experienced tutor with over 10 years of experience. I’ve been tutoring children from KS1 up to A-Levels as well as University students, for north of 10 years; I tutor English, Maths and Science. I, myself, have a degree in Medical Genetics, a PGCE in secondary science from the University of Leeds and am currently doing my third degree in Economics. I’ve had the pleasure of working with students who weren’t doing so well when we met, but who achieved amazing grades with their hard work and my dedication to them and I’ve had some great results from my students in their SAT exams, GCSEs and A-Levels. I have an open door policy, figuratively speaking - I’m available to my students or their parents, on my mobile, whenever they need or have any queries. I expect homework to be completed weekly and full concentration in class. I’m flexible, firm but fair with my students and always keep parents in the loop with regards to weekly progress. Just a note: I’ve set my hourly wage here at £33 but prices really do depend on the age range I am teaching. So please do ask about pricing for your particular child!
