Answer:
Quarantine may create heavy psychological, emotional, and financial problems for some people. To be effective, quarantine demands not only that at-risk people be isolated but also that they follow appropriate infection control measures within their place of quarantine.
Explanation:
Answer:
Changes can occur to physical properties of a substance, but the chemical composition of the substance remains the same.
Answer:
Are you talking about bacteria type viruses? because that's what I would assume.
Explanation:
Well, all viruses have a core of genetic material like RNA or DNA.
Viruses can have different families, geonomic makeup, host range and transmission mechanism.
I hope this helped in a way.
Answer:1. Pyruvate carboxylase
2. Phosphoenol pyruvate carboxy kinase
Explanation:
The conversion of pyruvate to phosphoenol pyruvate is catalyzed by two enzymes Pyruvate carboxylase and phosphoenol pyruvate carboxy kinase
1. Pyruvate carboxylase reaction
Pyruvate in the cytoplasm enters the mitochondria. Then, carboxylase of pyruvate to oxaloacetate is catalysed by a mitochondrial enzyme, pyruvate carboxylase. It needs the co-enzymes biotin and ATP.
The oxaloacetate formed has to be transported from the mitochondrial to the cytosol because further reaction of gluconeogenesis are taking place in cytosol.
2. Phoaphoenol pyruvate carboxy kinase (PEPCK)
In the cytoplasm, PEPCK enzyme then converts oxaloacetate to phoaphoenol pyruvate by removing a molecule of CO2. GTP or ITP donates the phosphate group.
The net effect of these two reactions is the conversion of pyruvate to phoaphoenol pyruvate. This circumverts the irreversible step in glycolysis catalyzed by pyruvate kinase (step 9 if glycolysis)
The stem has more things to transport that's why it has more vascular bundles. The roots only get water from the ground and moving nutrients from the soil to transfer it to the stem. Having more vascular bundles helps the stems to transfer things to leaves and other parts of the plants.
