In the middle of every atom is the nucleus
The nucleus contains two types of subatomic particles, protons and neutrons.
The protons have a positive electrical charge and the neutrons have no electrical charge.
A third type of subatomic particle, electrons, move around the nucleus.
The chromosomes of a cell are in the cell nucleus. They carry the genetic information.
Chromosomes are essential for the process of cell division, replication, division, and creation of daughter cells.
Chromosomes are made up of DNA and protein combined as chromatin.
DNA present on the chromosome not only carries most of the genetic information but also controls the hereditary transfer.
The closest star to Earth are three stars in the Alpha Centauri system.
They are an average of 4.3 light-years from Earth
The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair
The third star is Proxima Centauri. It is about 4.22 light-years from Earth and is the closest star other than the sun.
Most of the universe is empty space, called a vacuum, but it is an imperfect vacuum.
There are clouds of interstellar dust and the tiny particles that make up the solar wind.
In the inner Solar System, we find the “Inner Planets”
Mercury, Venus, Earth, and Mars – which are so named because they orbit closest to the Sun.
these planets have a number of key differences that set them apart from planets elsewhere in the Solar System.
What is inside blood vessel?
White blood cell
Our immunity cell
They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health.
Red blood cell
Red blood cells are round with a flattish, indented center, like doughnuts without a hole.
Hemoglobin is the protein inside red blood cells. It carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale.
DNA contains the instructions needed for an organism to develop, survive and reproduce.
To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies
There is an asteroid belt that separates the inner planets from the outer ones.
The outer planets are called the jovian planets, meaning huge gas giant.
These planets in order are Jupiter, Saturn, Uranus, and Neptune. Pluto comes after Neptune, but it is no longer considered a planet.
