Answer:
See the explanation below
Explanation:
From the balanced equation of photosynthesis:
6 moles of CO2 is required to produce 6 moles of oxygen.
Assuming that 5.2 g of CO2 reacts with water,
mole of CO2 = mass/molar mass = 5.2/44.01 = 0.1182 mole
Hence,
0.1182 mole of CO2 will yield 0.1182 mole of O2.
Mass of oxygen that will be produced from 5.2 g of CO2:
= molar mass of O2 x mole of O2
= 0.1182 x 16
= 1.9 g of O2.
<em>Note: Because the mass of CO2 is in two significant figure, the final answer was adjusted to be in two significant figure. The mass of oxygen can be computed depending on the mass of CO2 involved.</em>
Answer:
Explanation:
The epithelial tissues have a role that covers the inner lining of the organs of the body and also covers the outer surface of the body and lining of digestive system. If the body lacks the epithelial tissues then the microbes will invade the body and will cause diseases. The food and other foreign particles will harm the inner lining of the digestive system. This will result in internal leakage.
Explanation:
1. B"only proteins are formed from amino acids"
2. D. "They are carbohydrates made of simple sugars"
3. B "monosaccharides"
4. A
Answer:
Insular cortex
Explanation:
The insular cortex is found in the visceral sensory area and receives sensory input from the thalamus to the CNS. They play a role in emotions including self awareness, motor control etc and they also play a part in the regulation of the body's homeostasis.
As a result of its involvement in a reaction, an enzyme is unchanged.
Enzymes are catalysts that speed up chemical reactions that occur within the biological systems (they increase the reaction rate by lowering its activation energy). Enzymes react with substrate that binds to them (key-lock mechanism) and convert the substrate into the product. Most of enzymes are proteins by their structure but a few are catalytic RNA molecules-ribosymes.
Enzyme activity can be affected by other molecules (activators and repressors), pH, temperature etc.
