I believe it's saprotrophs
The main component of the cell membrane is a phospholipid bi-layer or sandwich. The heads (the phospho part) are polar while the tails (the lipid part) are non-polar.
Answer:
D. is responsible for most of the skin's structural strength.
Explanation:
A. contains no blood vessels.
False. The dermis contains blood vessels together embedded in it along with the sweat and sebaceous or oil glands, hair follicles, and nerve endings.
B. functions as a padding and insulation.
False. The fat layer that is located below the dermis is the one responsible for padding and insulation.
C. is divided into three distinct layers
False. The dermis is divided into only two separate layers. These are the papillary layer or the upper layer and the reticular layer or the lower layer.
D. is responsible for most of the skin's structural strength.
Yes, the dermis functions for providing the skin's structural strength because of it's thick fibrous and elastic tissue layer. This layer consists primarily of collagen and elastin that also allows for the skin's flexibility.
E. is made of epithelial tissue.
False. The dermis is made up of fibrous and elastic tissue. It is the epidermis which is composed of the epithelial tissue.
The information contained within the gene is copied into a new molecule by the process of transcription. Transcription is a process by which the information from one strand of DNA is copied into a new molecule called messenger RNA or mRNA. Even though mRNA contains the same information it is not the exact copy of the DNA segment. Protein molecules include DNA and RNA and the genetic information is copied into the protein molecules by the process of transcription and translation. Transcription is a process by which the information coded in DNA is transferred to RNA, where as translation is a process where mRNA provides information for the Ribosome the type of amino acid to link with. As amino acids are made up of proteins there will be transfer of information contained in a gene to be transferred to protein. Whereas the function of tRNA is to carry amino acids to ribosome during the transcription hence it does not carry any genetic information where as rRNA combines with the set of proteins to form ribosomes. These rRNA molecule moves along with the mRNA molecule but does not carry any genetic information.
Therefore the answer is d
