Im pretty sure its hypothesis
Lipids are unique because, they are made from one carbon skeleton unlike the other macro molecules groups which are made from smaller building blocks.
With the exception of steroid hormones, lipids are generally hydrophobic. Also lipids are relative small molecules when compare in size with other macromolecules.
Parenchyma cells synthesize and store organic products.
Answer:
The DNA testing process is comprised of four main steps, including extraction, quantitation, amplification, and capillary electrophoresis.
Explanation:
1. Separate white and red blood cells with a centrifuge.
2. Extract DNA nuclei from the white blood cells. ...
3. Cut DNA strand into fragments using a restriction enzyme.
4. Place fragments into one end of a bed of agarose gel with electrodes in it. 5. Use an electric current to sort the DNA segments by length.
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.
