Answer:
They were formed right after the "Big Bang" when our known universe originated from pure energy some billions of years ago. The energy was converted to the elementary particles (quarks, gluons, leptons etc...) from which protons and neutrons were formed. From these, atoms of different elements were produced
Answer:
presence or absence of a nucleus
Explanation:
These classification of organisms into broad domains is based on the present or absence of nucleus in the cell of an organism.
The archaea are prokaryotes and they lack a distinct cellular nuclei.
Bacteria are similar to archaea but bacteria have only one RNA polymerase
Eukarya have true nucleus and membrane bound organelles .
So, the variations in their cells are used to classify organisms into the broad categories
Answer:
The atomic structure of an atom involves 3 subatomic particles: the proton, neutron, and electron. The proton has a positive charge and is found in the core of the atom, with the neutral neutrons that also have a mass of 1 amu (atomic mass unit) just like the proton. The nucleus is the core of the atom and contains protons and neutrons and is practically the only area with mass. The electron cloud is basically an area surrounding the nucleus and it contains negative charged electrons. Electrons have no mass but are charged with a negative charge that keeps them. I really hope this helps :)
Explanation:
There is a helpful video that actually explains the structure of an atom in a rather fun way in just 2 minutes. It really does help big time and it's kinda funny if you look it up on YT and watch:
WKRP: Venus Explains the Atom
Have a wonderful great day :)
<span>Out of the following given choices;</span>
<span>a. cliff b. fault </span>
<span>c. plateau d. mountain</span>
<span>The answer is
b. A divergent boundary is a line at which two tectonic plates are moving away from each other. It is caused by the two magma convection currents in the mantle moving in opposing directions (one clockwise, the other anti-clockwise) hence dragging the crust with them. Therefore the biggest force at the boundary on the crust is that of pulling. This causes <span>fractures and faults on the earth’s crust.</span></span>
