Out Of the following choices given, the best soil for gardening will be a soil that is 10 percent sand, and 80 percent clay. The correct answer will be A.
Answer:
B. White light increases photosynthesis in plants.
Explanation:
Photosynthesis in simple term is defined as the process an organism uses the energy got from light in order to utilise CO2 and H2O for the production of glucose/organic matter and O2 as a gas. Examples of these organisms include,
plants, bacteria etc
6CO2 + 6H2O --> C6H12O6 + 6O2
Light can be absorbed by pigments in the oragnism cell like chlorophyll. Different pigments absorb different wavelengths of light. Leaves of a plant are green because the chlorophyll within them absorb all the other wavelengths of light in the spectrum and reflects green light. Absorption spectrum shows that red and violet light are the most absorbed whereas green light is most reflected.
A white light has maximum photosynthesis because white light is polychromatic i.e of varying colours so it could absorb blue, red, violet etc.
So therefore, White light increases photosynthesis in plants.
Answer:
The first living organism on Earth are Bacteria in the first era.
Explanation:
Bacteria are the first organism to leave be on Earth. They came into existence about 3.5 billion years in the first era in the waters of small oceans. Then there were anaerobic hetetrophic bacteria because the atmosphere was free of oxygen before. Cyanobacteria then became the first autotrophic organisms and first photosynthesizer that release oxygen to the atmosphere after photosynthesis.
Answer:
Option (4) weakening bonds in reactants
Explanation:
Enzymes increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting
Answer:
Viruses have to invade the body of a host organism in order to replicate their particles. Therefore, most viruses are pathogenic. The main difference between bacteria and virus is that bacteria are living cells, reproducing independently and viruses are nonliving particles, requiring a host cell for their replication.
hope this helps :)
