Answer:
It is important for scientists to study other planets because <u>it helps them learn more about Earth's history.</u>
<u></u>
Explanation:
In the expanse of the space-time continuum of the universe there are many celestial bodies from stars to planets that all formed at different times hence have different ages and are at different stages of formation.
Studying other planets helps reveal alot about our own planet, its history and its formation. By observing younger earth-like planets, scientists could understand how the earth looked like in its younger years and how it was formed.

The amino acids are the building blocks of the proteins.
Explanation:
The amino acids are the organic molecules made up of a carboxylic group, an amino group and a carbon side chain. The proteins are macromolecules, made up of amino acids. Many amino acids combine to form a protein. The structure of the protein depends on the sequence of the amino acids present in the structure of protein. A different protein has a different sequence of amino acids.
Answer:
Traditionally, some textbooks from the United States and Canada used a system of six kingdoms (Animalia, Plantae, Fungi, Protista, Archaea/Archaebacteria, and Bacteria/Eubacteria) while textbooks in countries like Great Britain, India, Greece, Brazil and other countries use five kingdoms only (Animalia, Plantae, Fungi, Protista and Monera).
Sexual reproduction leads to genetic variation because the sperm and egg that are produced contain different combination of genes than the parent organisms. sexual reproduction involves meiosis which is in the process of a cell doubling its DNA.
Answer:
It has four layers and attach with each other with desmosome.
Explanation:
The keratinocytes are arranged in four different layers which are the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. These cells are attached with desmosome which is a membrane protein. The presence of these four layers made a barrier against damage done by heat, UV radiation, water loss, pathogens etc. There are fewer cells at the end of the time as compared to the start because may be of the water pressure on the membrane or these cells for a long time.
