Answer:

Electricity is a secondary energy source that we get from the conversion of other sources of energy such as coal, natural gas, oil, nuclear power, and so on. These sources are known as “primary sources.” Primary sources can be renewable or non-renewable, but the electricity itself is neither.

List 4 targets of antibiotics.
Aleksandr-060686 [28]

Answer: Antibiotics targets the synthesis of protein, nucleic acid, folate and cell wall.

1. Synthesis of protein; antibiotics binds to either 30s or 50s ribosomal subunits blocking the polypeptide from the exiting the tunnel thus inhibiting a full completion of protein expression or production.

2. Nucleic acid synthesis; Antibiotics also act by inhibiting genetic expression, DNA transcription and replication where DNA makes exact copies of itself, as well as RNA molecules preventing bacterial growth.

3. Cell wall synthesis; Inhibition of cell wall synthesis in microorganisms will prevent it from replication and growth.

4. Folate synthesis; Folic acid also known as vitamin B9 helps in DNA replication and cell division. Folate antagonists such as aminopterin kills bacteria by preventing folic acid production required for DNA replication.

the graph shows how the rate of photosynthesis of a plant varies with light intensity. interpret the graph and justify statement
dezoksy [38]

The graph shows that the rate of photosynthesis increases with increased light intensity, other conditions being constant.

<h3>Photosynthesis and light intensity</h3>

From the graph, the rate of photosynthesis increases with an increase in light intensity.

At low light intensity, the photosynthesis rate increases with an increase in the concentration of carbon dioxide and level off at some point.

With medium light intensity, the rate of photosynthesis is about twice that of low light intensity under the same concentration of carbon dioxide. It also gradually levels off when the concentration of carbon dioxide reached a particular point.

The same trend applies to high light intensity. The rate of photosynthesis increased accordingly, much more than low and medium-intensity light.

Both light and carbon dioxide concentration can limit the rate of photosynthesis. When both factors are abundant, photosynthesis can be limited by other factors such as water, nutrient, etc.
