Answer:
The cell membrane
Explanation:
The cell membrane, sometimes also known as the plasma membrane, serves as a clear boundary between the inside of a cell and its outer environment.
<h3>
The other four bases will be 5'-ATTC-3'</h3>
Explanation:
A pallindromic sequence of DNA is the sequence which could be read the same in both direction on both strands. Among nucleotide Bases A (adenosine) pairs with T (thymine) with a double bond while G(Guanine pairs with C (cytosine) with triple bond. Since the complimentary strands run in opposite direction, then if the eight bases on one strand is 5'-GAATATTC-3' then the sequence on the complementary strand will be 5'-GAATATTC-3'.
This causes a phenomenon referred
to as valve regurgitation. This reduces the flow of blood in the blood vessels
and causes a reduction in the oxygenation of tissues of the body. This causes homeostatic signaling by the body resulting
in the exertion
of the heart pumping and increased breathing (heavy breathing). This is why
some of the symptoms include shortness of breath,
fatigue,
and light-headedness.
Answer:
Its D, The cell membrane(also known a the plasma membrane) has a job in which it has to allow passage in and out of the cell. Therefore it can prevent harmful substances from entering the cell. Think of it as security, either allowing you access or denying you depending on if you're a threat
