The major organ of the circulatory system that causes blood to flow through the body by its pumping action is the heart.
Hi! I'm assuming you know the four states of matter- solid, liquid, gas, and plasma.
Putting them into a crime scene, however, is tricky.
Depending on which type of crime scene it is, there will be different types of states of matter in each, or possibly multiple.
Liquid can be seen as blood if it was a murder. Solid can be seen in that same crime scene if the murderer by chance left his knife, gun, or solid device they used to commit the murder. In other cases, gas can be seen used to kill someone because of it's toxicity. Plasma is a hard one, though, but can be seen in blood as well, because our blood is made up of plasma and other materials.
Hoping I helped, and I'd love to receive brainliest answer! :)
Answer:
The bottom one shows how the circulatory system of a fish functions.
Three factors that determine the reactivity of elements are the
valence electrons are the electrons in the outermost electron shell of an atom.
The number of electrons in an atom's outermost valence shell governs its
bonding behaviour. That is why in periodic table the elements were put together
according to their numbers of valence electrons.
METALS
The most reactive kind of metallic element is a metal from
Group 1 sodium or potassium.
An atom in Group 1 has only one valence electron.
NON-METALS
A nonmetal tends to attract another valence electrons to
attain a full valence shell.
