1) No . The male seahorse don’t have female organs to give birth .
2) Its because , in a steel , like a metal . It has free electrons which
increase the rate of vibration or the rate of transferring vibration . Causing the vibration of sound wave to be able to travel through the steel faster then usual .
3) Each time we blink , moisture will be spread across our eyes . If we don’t blink , our eye will be dry and eventually vision will be worsen .
4) I don’t know how to do

Atoms

The atom is a basic unit of matter consisting of a dense central nucleus surrounded by a cloud of negatively charged electrons . the nucleus is the very dense region consisting of nucleons , protons and neutrons at the center of an atom . The atomic nuckeys contains a mix of positively charged protons and electrically neutral neutrons . the electrons of an atom are bound to the nucleus by the electromagnetic force .

The name atom came from the Greek , which means uncuttable , or indivisible . Something that cannot be divided further . It was first proposed by early Indian and Greek Philosophers . During the 17^th and 18^th centuries , its was said that atoms are physical basis for this idea by showing that certain substance could not be further broken down by chemical methods.

Only during the 19^th and early 20^th centuries , its was proven that the subatomic components and structure inside the atom , thereby demonstrating that the ‘atom’ was divisible , proving quantum mechanics were used successfully to model the atom .
