Answer:
Explanation:
The two requirements for a measurement are a <u>number</u> and a <u>unit.</u>
For example, here is a measurement:
38.6 cm
The <u>number</u> is 38.6 and the <u>unit</u> is cm, or centimeters.
Therefore, both <em>number </em>and <em>unit</em> are correct.
7.) Yes, both are insects.
8.) Homologous since the organisms are closely related
If it is already balanced because the compounds aluminum(Al) and oxygen(O) have the same number of atoms
Answer:
No, since DNA is quite fragile and the methods used in this experiment tend to break it apart. Scientists, therefore use special chemicals and procedures to protect DNA. For example, they add chemicals to control the acidity of the solution. Scientists use other chemicals to cut DNA apart very precisely to look at one part at a time. This process can take several days to several weeks
Explanation:
Is the DNA in any cell in the human body the same? Explain your answer.
Yes, in a multicellular organism (such as a human or a strawberry), all cells contain the same DNA. However, multicellular organisms have many different types of cells. For example, humans have liver cells, muscle cells, skin cells, brain cells, and the list goes on. It is not the DNA that makes each cell different but rather the way it is regulated by the cell. The combinations of genes that are turned on and off are what determine the shape of the specific cell along with its specific function.
Answer:
The cell membrane is located on the outside of a cell. It acts as a border that separates the cell from other cells or substances in the environment.
Explanation:
The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
