Answer: Agriculture is increasingly harming the environment for multiple reasons. One being deforestation. Deforestation reduces ecological services it provides humans produces large amounts of Carbon Dioxide which adds to greenhouse gases -> which add to our current problem with climate change. Additionally, the pesticides and fertilizers agriculture uses can be harmful to the nearby ecosystems as it can end up in surrounding rivers which causes it to cycle back.
Answer:
How do your cells know what to do? Just like builders have blueprints to tell them how to build a house, your cells also have instructions. Your cells' instructions are molecules of DNA.
What is DNA?
DNA is the material that makes up our chromosomes and stores our genetic information. When you build a house, you need a blueprint, a set of instructions that tells you how to build. The DNA is like the blueprint for living organisms. The genetic information is a set of instructions that tell your cells what to do.
DNA is an abbreviation for deoxyribonucleic acid. As you may recall, nucleic acids are a type of macromolecule that store information. The deoxyribo part of the name refers to the name of the sugar that is contained in DNA, deoxyribose. DNA may provide the instructions to make up all living things, but it is actually a very simple molecule. DNA is made of a very long chain of nucleotides. In fact, in you, the smallest DNA molecule has well over 20 million nucleotides.
Explanation:
A mixture of equal amounts of two enantiomers <span>is called a racemic mixture.</span>
Astronomers use light years to measure distances in space because space is so massive and distances so far that conventional numbering is inadequate and unmanageable. One light year is a distance measurement equivalent to six trillion miles.
