Answer:
Pyruvate kinase
Explanation:
Yeasts convert glycerol and sugars into glyceraldehyde 3-phosphate (G3P) through independent pathways. Then, G3P forms pyruvate and, in some circumstances, pyruvate is converted in ethanol, which can be used as energy sources. If the mutation affects any reaction before G3P formation, it will only affect yeast growing either on sugar or pyruvate but not both.
Pyruvate kinase is the only enzyme on the list acting after G3P is formed and before pyruvate is formed. All other options are enzymes acting only in the formation of G3P from sugars. Meaning that only pyruvate kinase mutants will lack the ability to grow on both sugars and glycerol.
Answer:
Oxygen is a colourless, odourless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere.
Answer:
The picture is upside down
Explanation:
- Provide the family with lead education
- Consider treating the child with appropriate chelation therapy
- Refer the child to a clinical center specializing in lead poisoning
If the blood lead level<span> of a preschooler is found to be between 20 and 44 mcg/dL, the nurse should provide lead education to the family. The nurse should also consider treating the child with appropriate chelation therapy. The nurse may refer the child to a clinical center specializing in lead poisoning. The nurse should refer the child to social services if the child’s blood lead level is between 15 and 19 mcg/dL. The nurse should immediately provide diagnostic testing and initiate chelation therapy if the child’s blood lead level is 70 mcg/dL or greater.</span>
