A vector is any animal that transmits disease causing organisms (pathogens or germs) into a host.
Note: Ideally, a vector should be an animal. It is important to point out this fact because we have other organisms that aren't animals, yet are still capable of transmitting diseases.
Please read on the Basic Introduction to Biology here.
A disease is a deviation from the normal physiological and anatomical state of an organism which is usually associated with some specific signs and symptoms.
Please read on Micro-organisms causing Food, Water and Air Borne Diseases here.
Note: A host is an organism on which another organism (called a parasite) lives and feed on. They usually suffer in a parasitic relationship.
Please read on Homeostasis here.
The disease causing organism (pathogen or germs) when inside the vector causes no disease to it; but as soon as the vector introduces the pathogen into the host, it affects the physiological system of the host; and as a result brings about diseases in the infected host.
For example, the pathogen for river blindness in humans is Onchocerca volvolus. This pathogen initially lived inside the blackfly which happens to be its vector.
The Onchocerca volvolus (within the blackfly) causes no harm to it but as soon as the blackfly introduces it into its host (humans), it may then bring about river blindness to its host.
Please read on Immunization here.
The table below shows some vectors, the micro organism they carry and the disease they transmit to humans.

Amazing facts in Basic Science
Rasceta is the name given to the lines on your ✋ palm ✋
Goats have rectangular pupils in their eyes.
Think of the pupil as a hole located in the centre of the iris of the eye.
Note: To get an idea of an iris; when one is said to have blue eyes, it's because the iris is blue

🍓 strawberry 🍓 has it's seed outside the fruit
It actually takes 🍍 pineapples 🍍 2 years to grow

NOTABLE POINTS IN Basic Science
The eyebrow is an area of dense, delicate hair just above the eye.
Eyebrows perform two main functions:
Eyebrow modified in the form of Nike.

Note: Eyebrows can also be modified to enhance beauty; especially female beauty.
All fruits have seeds. There is nothing like a naturally occurring seedless fruit. Even banana, coconut and pineapple have all got seeds.
Weight can be defined as the force of gravity acting on an object. If you traveled to space, you would be weightless because there isn't any force of gravity acting there. We all have weight on earth becasue the force of gravity acts here. Weight is measured in Newton
Massis the amount or quantity of matter/material contained in a body, For instance, everything you are composed of, both from within and outside will make up your mass. Mass is constant throughout the universe. You will have the same mass on earth and moon. Mass is measured in gram or kilogram. Mass is quite different from weight.
Matter is anything that has mass and occupy space. Matter can exist in four states namely:
