<h2><u>
Answer:</u></h2>
<u><em>The nucleus has three major functions: </em></u>
- Store the inherited material of the cell (DNA)
- Coordinates the activity of the cells ( i.e. growth, intermediate metabolism, protein synthesis and cell division/ reproduction).
- It maintains gene safety and monitors the functions of the whole cell through the regulation of genetic expression.
Answer:
1. Plants utilize some of the incoming energy derived from photosynthesis for their own self-maintenance.
3. Plants and algae carry out both photosynthesis and cellular respiration.
5. Plants, algae, and cyanobacteria utilize light energy from the sun into their own biomass.
Explanation:
The gross primary productivity (GPP) of an ecosystem represents the rate at which the solar energy is captured during photosynthesis in a given period. Producers (plants, algae and cyanobacteria) perform cellular respiration to provide energy for their life processes. Cellular respiration consumes part of the total photosynthetic output. The energy available in tissues of producers after cellular respiration is called net primary productivity (NPP).
Therefore, NPP is the amount of biomass or the energy stored in the tissues of the producers for growth after cellular respiration for their normal daily activities and self-maintenance. So, NPP is always less than GPP.
The control group would be plant d because nothing is being done to it. While all the other plants listen to music, it is the only one that doesn’t which shows the difference between a normal and altered result
