Where they have there effect on the tissues cells
I got you :)
The molecular clock (based on the molecular clock hypothesis (MCH)) is a technique in molecular evolution that uses fossil constraints and rates of molecular change to deduce the time in geologic history when two species or other taxa diverged. It is used to estimate the time of occurrence of events called speciation or radiation. The molecular data used for such calculations is usually nucleotide sequences for DNA or amino acid sequences for proteins. It is sometimes called a gene clock or evolutionary clock.
A. Lipid bilayer: the phospholipid bilayer is the membrane of a cell. The bilayer contains lipids, membrane proteins, cholesterol, receptors for various molecules, pumps to transport ions and solutes against the concentration gradient, and many other items necessary for a cell to function and work together with other cells.
b. Osmotic pressure: Osmosis is the flow of water across a semipermeable barrier from an area of low solute concentration to high solute concentration. Osmotic pressure is the lowest possible pressure to prevent this water movement.
c. Endoplasmic Reticulum: the Rough ER synthesizes proteins for use outside the cell. The Smooth ER produces lipids and some steroidal hormones.
A. Lipid Bilayer is therefore the correct answer. Osmotic pressure does not involve the various components of the cell membrane, and the ER's produce proteins and hormones. Therefore A is right.
Hope this helps! :) Let me know if you need a clarification.
Answer:
carbon bond is a covalent bond between two carbon atoms.
Explanation:
<span>Palpation and percussion can cause an increase in normal bowel sounds and hide abdominal vascular sounds. Therefore it is wise to perform auscultation prior to percussion and palpation during clinical assessment of the renal system. Palpation should be avoided if a client is suspected of having a tumor because it could harm the client. It is more important as part of clinical assessment of the renal system to listen for bruit by auscultating over the renal artery. Bruit indicates renal artery stenosis. The nontender areas should be examined prior to tender areas to avoid confusion regarding radiating pain from the tender area being percussed.</span>
