So, the instrument that is used once are kept separated.
Answer:
The correct option is D. The nerve and red blood cells will turn on and off different portions of their DNA, using different genes to make different proteins.
Explanation:
A zygote is totipotent which means it has the ability to differentiate into any cell type found in the body along with the placental cells.
The nerve and red blood cells are specialized cells and they cannot differentiate into any other cell type.
All cells in the body are formed from the zygote. All the cells in the body have the same chromosomes and the same genes. However, these cells become specialized because certain part of the DNA is activated in one type of cell which helps it perform its function. Different genes are activated in different specialized cells which are able to transcribe and translate.
Answer:
the drug was pulled from the market because of the evidence that it was a(n) <u>teratogen</u>
Explanation:
Teratogens are drug or other agents that cause physical or functional bnormalities in fetuses that are exposed to such agents. A typical example is alcohol. The degree of the abnormality on the fetus depends on a number of factors which are:
- the type of agent
- the developmental stage of the fetus
- the duration of exposure
- the concentration of teratogenic agent being exposed to
ATP
Adenosine 5'-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups. The word adenosine refers to the adenine plus the ribose sugar.
