Answer:
Abnormal, unhealthy cells develop
Explanation:
Gene expression is the process through which genes are turned on through transcription, and to some extent through the translation of the mRNA.
Gene expression is highly regulated to ensure the cell can create the correct combination of proteins to carry out it's tasks. If gene expression is out of control, the mRNAs that are transcribed in the cell are not properly regulated, and therefore the proteins in the cell are not regulated. Since proteins carry out essentially every function in the cell, the cell becomes unhealthy, and incorrectly uses its resources.
Accurate control of gene expression also ensures that the cell can perform specialized functions, it is what makes a heart cell distinct from a brain cell, for example. Therefore, if it is out of control, cells will not be specialized correctly.
Answer:
Air temperature
Explanation:
These variations in air pressure are due to temperature differences caused by variations in solar energy received at the surface of the earth
The direct source of energy to move the sailboat is probably wind, since wind is what pushes the sail of the sailboat, which is what propels the sailboat forward.
Hope this helps!
Answer:
the drive-reduction theory
Explanation:
The drive-reduction theory is one of the theories of motivation.
This theory contains the idea that a physiological need creates a drive, which in turn motivates an organism to satisy their need.
The theory targets homeostasis or biological balance.
When there is a need such as lack of water, the need would cause a drive to be developed (thirst).
The drive would activate a response (search for water to drink).
The response is then terminated when the need has been satisfied.
Reverse transcriptase use mRNA to
form DNA apex
Reverse transcriptase is a broad
family of enzymes that play a unique role in the flow of genetic information. The
synthesis of DNA from an RNA template through reverse transcription produces
complementary DNA. Reverse transcriptase use an RNA template and a short
primer complementary to the 3' end of the RNA to direct the synthesis of the
first strand complementary DNA, which can be used directly as a template for
the Polymerase Chain Reaction.
