Comets are most like planets have elliptical orbits
Answer Choices:
DNA provides the energy needed for an organism to grow and function
DNA is copied into mRNA, which controls cellular functions
DNA codes for proteins, which allow an organism to grow and function
DNA unzips and each strand codes for a different amino acid
Answer:
DNA codes for proteins, which allow an organism to grow and function
Explanation:
DNA provides the energy needed for an organism to grow and function - this is false. DNA does not provide energy. A molecule called ATP, mostly produced by cellular respiration, provides energy for the cells to grow and function.
DNA is copied into mRNA, which controls cellular functions - this is false. While it is true that DNA is copied into mRNA, mRNA does not directly control cellular functions. Instead, mRNA is translated into proteins.
DNA codes for proteins, which allow an organism to grow and function - <u>this is true, as indicated above, DNA is transcribed to mRNA which is translated into proteins. Proteins carry out essentially all the functions in the cell</u>
DNA unzips and each strand codes for a different amino acid - this is false, DNA is transcribed into mRNA. Each mRNA codon (three bases) codes for a different amino acid
Objects with like charges repel/repulse each other while opposite charges attract each other
The direction of an electric fields is alway the direction electrons would naturally move.
Not sure about the last one, my gut instinct is opposite.
Totipotent stem cells have the ability to develop into any kind of cell found in the
human body.
When the sperm fertilizes the egg, creates the zygote which is the fist totipotent cell. After that, in the first cell divisions more totipotent cells
are produced. Within several days, these totipotent cells produce even more totipotent cells and after four days the cells begin to specialize.
The correct answer is Polar climates.
The polar climate areas are featured by an absence of warm summers. Each month in a polar climate exhibit a mean temperature of fewer than 10 degrees Celcius. Even in their warmest months, they have a mean temperature of fewer than 10 degrees Celcius.
The countries coming under the polar climate regions are Alaska (United States), Yukon (Canada), Greenland (Denmark), Finland, Norway, Iceland, Sweden, and Russia.
