D. A change in the amount of polar ice will alter how ocean currents move
<span>The cell uses oxygen to break down glucose which releases energy. This energy is stored in the form of ATP.</span>
Bio refers to study of living things + technology (is pretty straightforward- i dont think i need to explain this)
This means Vincent modifies the DNA of bacteria to study the function of their genes is the correct answer :)
DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical method while on the other hand, Polymerase chain reaction (PCR<span>) is a technique used in molecular biology to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.</span>
A cell membrane pump helps human cells to maintain a relatively constant sodium and potassium concentration.
<u>Option: A</u>
<u>Explanation:</u>
Sodium potassium pump is a plasma membrane protein that utilizes energy ATP — Triphosphate Adenosine turning into ADP — Adenosine Diphosphate to deliver intracellular and extracellular sodium (NA+) and potassium (K+) ions sequentially. The purpose of this entire mechanism is to preserve cell equilibrium.
The extracellular medium has a greater concentration of Na while the K concentration of the intracellular fluid is lower. Proteins trap sodium ions in the cytoplasm and pump them out from the cells to preserve cell stability while preserving concentrations. Within the cells proteins inject potassium ions into the cell.
