Which type of RNA carries the genetic information from DNA to the site of protein synthesis?

Answers


The type of RNA that carries genetic information to the site of protein synthesis is messenger RNA or mRNA in short.

The first step for this to occur takes place in the nucleus of the cell in a process called transcription. In this process, the genetic information for the synthesis of a particular protein is copied onto mRNA, in a triplet base format and it is in code,

mRNA then leaves the nucleus and enters into the cytoplasm of the cell where it attaches itself to a ribosome. A ribosome is the site where proteins are synthesized and is also nicknamed the "work bench" of the cell.

Another type of RNA called tRNA then reads the coded information on the attached mRNA and recognizes a triplet of bases on it and decodes the information. This process is called translation. tRNA then fetches the amino acid that corresponds to that triplet of bases from the cytoplasm and into the ribosome where the amino acid is linked to others to form a chain and  thus a protein.

Saliva begins to change food starch into?

Answers

The first step of chemical digestion starts in the mouth. Saliva, the fluid released by the salivary glands in the mouth, contains an enzyme that breakdowns food starch and turns it into simple sugars. This enzyme is called amylase or also known as alpha-amylase or ptyalin. 

Saliva begins changing starches into sugar while still in the mouth.

How is a delta formed

Answers

When a river reaches a lake or the sea the water slows down and loses the power to carry sediment . The sediment is dropped at the mouth of the river. Some rivers drop so much sediment that waves and tides can't carry it all away. It builds up in layersforming a delta.

A group of scientists are studying the effects of different fertilizers on the growth of pea plants. They began their study with 10 pea plants. They gave each plant a different type of fertilizer and tracked their growth over a period of 2 months. What’s the independent variable in this experiment?

Answers

The answer is a type of fertilizer.

An independent variable is variable that is not affected in the experiment. It is what experimenter controls. On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected during the experiment.
In this case, the growth of pea plants depends on different types of fertilizer. So, the growth of pea plants is the dependent variable and different type of fertilizer is the independent variable.
