Answer:
False
Explanation:
The primary productivity is higher than the secondary productivity, or any other productivity for that matter. The primary productivity comes from the producers, and it basically represents the total biomass of the producers. The producers outnumber and outweigh all other organisms by far, so they produce significantly much more biomass than any other type of organisms, thus being rated on the top for productivity.
Answer:
27,000
Explanation:
The provided statement talks about an estimate of energy release by an Earthquake with a magnitude of 4 to a magnitude of 7. According to the statement, for the moment magnitude scale, 31.5 times more energy is released with increase of one magnitude scale. Therefore, if we take a rounded value of 31.5 as 30 and multiply it three times (30 X 30 X 30) to represent 3 scales (4 to 7) on moment magnitude scale, we will get 27,000 times more energy.
The cell will begin to die and shut down.
Answer:
Water along with carbon dioxide and oxygen are the agents of chemical weathering to support that statement.
Explanation:
- Chemical weathering is the continuous process that makes the rocks weak and decompose by changing its composition.
- Water is the main agent for chemical weathering, the molecules of water separates the ions from their existing compounds and edges them.
- Water has the ability to completely dissolve some minerals. for example, salt.
- Oxygen also takes part in chemical weathering by the process called as oxidation.
- Similarly carbon dioxide initiates weathering by the acid rain.
Answer:
A) Peptidoglycan
D) Lipopolysaccharide
Explanation:
Gram-negative bacteria have a cytoplasmic membrane, a thin peptidoglycan layer, and an outer membrane containing lipopolysaccharide. There is a space between the cytoplasmic membrane and the outer membrane called the periplasmic space or periplasm.
