1. Light

What is it?

· Is a form of electromagnetic energy. Very small particles called photons move in a wave pattern.

· Visible light is the light which allows you to see the colors and shapes of objects.

· The sources of energy can be natural or artificial.

A force: is a push or pull acting upon an object as a result of its interaction with another object.Their effects: they can make an object move, change the speed of it, change the direction, change the shape..  2 types of forces:CONTACT FORCES Frictional ,Tension, Normal, Applied, Spring .ACTION-AT-A DISTANCE FORCES. gravitional, electrical and magnetic.tension: force that a spring or similars exerts on the object in these type of problems. Resistive Forc: prevents the slipping or sliding of 2 surfaces in contact. Normal force: exerted on an object which is in contact to another stable object. NEWTON LAWS

Variety:means differences between individuals.CLONING: we take a somatic cell with 2n.the somatic cell is put in a media to lose its identity.we remove the nucleous of an egg cell.we fused the somatic cell with the eeg cell and through this the somatic cell enters inside the egg cell. we put the final cell inside the another sheep.we will get a clone from the first sheep. Clone: is an individual which has been produced asexually from its parents. Cloning:asexual way of reproduction. Cloning plants:we can produce new plants by taking cuttings from the older plant and them you plant to make possible the growing. Difference between natural and artificial embryio twinwing:natural->in the first step the zygote divides into two identical embryios. Artifical-> in the first step the man separate the zygote and makes two identical embryos. difference of twins:identical->comes from the same egg cell. twins-> comes one from different ovul. How is a gene taken out from one organism to b ... (Continue)
