Answer:
Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression.
During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of nucleotide bases, but they have slightly different chemical properties. The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.
Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm. The mRNA interacts with a specialized complex called a ribosome, which "reads" the sequence of mRNA bases. Each sequence of three bases, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time. Protein assembly continues until the ribosome encounters a “stop” codon (a sequence of three bases that does not code for an amino acid).
The flow of information from DNA to RNA to proteins is one of the fundamental principles of molecular biology. It is so important that it is sometimes called the “central dogma.”
Answer:
False.
Explanation:
Carbon Dioxide is considered a greenhouse gas. This means that when released into the atmosphere, it forms a "blanket" of gas that traps heat. This phenomenon causes a rise in temperature.

Sentences:
#1 A Hammerhead shark is a type of shark that comes from the family, Sphyrnidae. These sharks were named for their head shape, <span>which are flattened and laterally extended into a "hammer" shape.
#2 The Wobbegong shark is known as a type of carpet shark and is </span>found mostly in the shallow temperate and tropical waters of the western Pacific Ocean. As well as in the Eastern Indian Ocean.
#3 Sand Sharks come from the Odontaspididae family. These sharks can be found world wide, and mostly in tropical waters. It can also be known as the Sand Tiger Shark in both the US and in the UK.<span>
#4 The Sawshark has a l</span><span>ong, saw-like rostrum edged with sharp teeth. They use this to slash and disable their prey.
#5 An Angelshark contains a flattened body and wide </span><span>pectoral fins, that offten give them a strong resemblance to rays.
#6 The Cat shark can also be refered to as the Bamboo shark. This species finds comfort in swing very close to the ground.
#7 Cow Sharks belong in the </span><span>Hexanchidae family because of their additional pair of gill sets.
#8 The Bramble shark can be found in the </span><span>eastern Pacific Ocean, and in tropical and temperate waters worldwide.
#9 A Carpet shark can commonly be mistaken for a Wobbegong shark, although they can sometimes be the length of a whale shark.
#10 The Alopias shark can also be known as a Thresher shark and has the ability to</span> <span>inhabit both coastal waters and oceans far from land, from the surface to depths of at least 360 meters.
#11 The </span><span>Carcharhiniformes shark can also be known as a ground shark and they can weigh as much as a Bull shark.
#12 The Heterodontus is a bull shark </span><span>that is a small order of basal modern sharks. </span><span>
#13 </span>Sharks in the Swualiformes family, have two dorsal fins, which usually possess spines.
#14 The <span>Hexanchiform shark has only one dorsal fin and six or seven gill slits. This species is extinct.
#15 The Smooth-Hound Shark is narrow finned and is sometimes referred to as the </span>Florida smooth-<span>hound.
