Answer:
2 feet
Explanation:
One of the basic requirements of scaffolding is that access must be provided when the scaffold platforms are more than 2 feet above or below a point of access.
Therefore, you must have a safe way to access a scaffold over 2 feet.
The answer is <span>B. fibrin.
Through the process of elimination: thrombin and thromboplastin are enzymes so these choices are incorrect. Platelets are actually cells, which leaves us B. fibrin as the correct choice.
</span>A fibrinogen is a protein involved in the formation of blood clot. It is converted by enzyme thrombin into fibrin during blood clot formation.
Answer:
1. The substition that least affect on the enzymatic activity would be (arginine) because lysine is( positively) charged at physiological ph.
The substitution that have effect most on the enzymatic activity would be (Glu) because it is (negatively) charged at physiological pH.
Explanation:
Fill In The Blank. In three separate site-directed mutagenesis experiments, scientists altered a Lys residue in corn PEP carboxylase to an Asn, Glu, or Arg. The substitution that you would expect to have the least effect on enzymatic activity would be ARGININE because it, like Lys, is POSITIVELY charged at physiological pH. The substitution that you would expect to have the most effect on enzymatic activity would be GLU because it is NEGATIVELY charged at physiological pH. (Use structure tables if you need to.)
The answer would be D. Every egg starts in the ovaries. Hope this helps.
Answer: An excess of a product of one reaction causes the enzyme of another reaction to stop working.
