Answer: Loess is the fine grained material that has been transported and deposited by the wind. The answer is <u>A.</u>
Explanation:
Since the wind can carry these types of material (find grained) father than sand, and also higher up, they are generally found very far from their original place of origin.
Loess is no larger than 50 micrometers in size. It is coarse in texture like clay, but finer than a grain of salt.
Answer:enzymes
Explanation:during digestion, food is broken down by chewing in the mouth.enzymes also acts on foods to reduce them into simpler constituents.enzymes acts on food in the mouth, stomach, intestine etc.
Enzymes that acts on proteins helps to break the peptides bonds present in proteins.they break up the polypeptide chains into amino acids .An example is trypsin .the conditions necessary for these enzymes to acts may be specific.some require acidic environment while others require basic environment.pepsin for example requires stomach hydrochloric acid to be converted from it's inactive form, pepsinogen.
The resultant Amino acids are then absorbed in the small intestine
The correct answer is: b. It is free to bind to another promoter and begin transcription
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex.
RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.
