A. Low-lying coastal areas may flood.
C. Fertile land may become dust bowls.
D. Air quality decreases, posing threats to human health.
Answer:
When carbon dioxide is released into the environment, typically due to human activities and respiration in animals, it gets trapped in the atmosphere. Carbon dioxide is just one greenhouse gas, but as all of the gases accumulate in the Earth, the temperature begins to rise globally. There are many implications to this, including the melting of glaciers, bleaching of corals, and increasing necessity for air conditioning systems and ventilation. When glaciers melt, they become a part of the ocean, meaning that as more glaciers begin to thaw out, the ocean will being to grow up and out. As sea levels rise, humans and animals are left with no choice but to being moving to higher points of elevation to avoid sinking. Another consequence of glacial melting is the loss of habitat for animales in many environments. Those living in glacial areas will begin to lose the snow and ice they are built to withstand. Those living near the sea or at low points of elevation will lose their habitats as it sinks deeper into the ocean. Another problem with global warming is coral bleaching. As the ocean warms up from the rising temperature, corals will being to overheat until they become ”blaeched’ whihc essentially means that they die. Lastly, global warming will create an increasing necessity for air conditioning systems and ventilators. People who do not have access to these things or cannot afford them can risk health complications. Global warming is a problem that cannot be ignore and the world needs to take more steps to plant trees and grasses that can photosynthesize the carbon dioxide into oxygen.

4 steep slope and impermeable bedrock
Answer:
3
Explanation:
B. shared; atoms
C. transferred; ions
D. transferred; atoms
Option B is correct.
B. shared; atoms
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
Answer:
B. shared; atoms
Explanation:
Covalent bond is formed by sharing of electrons between two atoms. In this way full outer shell is achieved by both the atoms. Since there is no gain or loss of electrons, no ions are formed in the process.
It is usually formed between the atoms of similar electronegativity. It can be of many types like sigma bond, pi bond etc. If a pair of electrons is shared, it's a single bond. If two pairs are shared, it's a double bond and if three pairs are shared, it's a triple bond.
The gene coding for the protein untwists and

O RNA nucleotides form complimentary base
pairs with the DNA bases.
Hydrogen bonds and sugar-phosphate bonds
form and the mRNA strand is synthesized.
mRNA peels off the DNA and moves to the
cytoplasm.
RNA nucleotides form complimentary base pairs with DNA bases. Hydrogen and sugar-phosphate bonds form and the mRNA is synthesized.
Explanation:
The process of mRNA formed by DNA is called transcription. The genes coding for the protein is present on DNA as a nitrogenous base or nucleotides.
Transcription takes place inside the nucleus with the assistance of major enzyme RNA polymerase. In transcription 5'to3' single strand of RNA is synthesized which is complementary to the 3'to5' strand of DNA. The sequence of DNA has promoter sites which will be recognized and DNA will unzip to form transcription bubble. Several transcription factors and enzyme will be required to synthesize mRNA.
This mRNA after some modification would become primary transcript and pass on to the cytoplasm where protein synthesis will take place.
