Answer:
Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane
<span>The two most common ways are the use of a water restrictor in the shower head, most of the heads in the U.S.A are equipped with a water restrictor. Secondly, the commode water tanks have been made smaller using less water per flush. Some conservation of water may be gained by using "instant" water heaters in the shower/bath and basin rather than a hot water tank type heater. Locating an instant water heater near the output of the water reduces the need to let the water run until it becomes hot at the output. </span>I hope that this is the answer that you were looking for and it has helped you.
Answer:
C. an amino acid
Explanation:
Nucleic acids are one of the four biological molecules found in living systems, which function in the storage and transmission of genetic information. Nucleic acids are polymers and like every other polymers, they are made up of monomeric units called NUCLEOTIDES joined together by covalent bonds called phosphodiester bonds.
NUCLEOTIDE is structurally composed of three major components viz:
- A five-carbon sugar: This can either be ribose or deoxyribose depending on whether the nucleic acid is a RNA or DNA respectively.
- Nitrogenous base: The four nitrogen-containing bases found in nucleic acids are Adenine, Guanine, Cytosine, Thymine (DNA) or Uracil (RNA).
- Phosphate group
Answer:
Explanation:
Mutations may or may not affect the phenotype because they can occur in coding or non coding areas of the DNA. If they occur in coding areas of the DNA, the protein that is coded in that part could be processed incompletely or have a different amino-acid in some part of its structure, this would affect the phenotype. If they occur in non coding areas, this would have no effect on the phenotype.
