Answer:

False

Explanation:

Lipopolysaccharides are substances that have both lipid and polysaccharide. LPS layer is the characteristic feature of gram-negative bacteria. The LPS layer is present in the outer membrane of the cell envelope of gram-negative bacteria. It is not found in Gram-positive bacteria.

Broad-spectrum drugs are the chemotherapeutic agents that are effective against several kinds of pathogens while the narrow spectrum drugs target only a limited type of microbes. Therefore, an antibiotic that attacks the LPS layer would be effective against Gram-negative bacteria only which in turn makes it a narrow-spectrum drug.

sweet [91]

Answer:

Explanation:

The amount of biomass that is produced in an area during a given time is referred to as primary production/productivity.

<h3>What is biomass?</h3>
  • Renewable organic material obtained from plant and animal sources if referred to as biomass.
  • Primary productivity is the production of organic compounds through the process of photosynthesis, with the help of solar energy.
  • Primary productivity is measured as biomass produced per unit area over a give time period
  • It is usually expressed either in weight or energy.
  • There are two ways to express primary productivity:

a) Gross Primary Productivity(GPP): Takes into account the total energy produced in the ecosystem.

b) Net primary Productivity(NPP): Takes into account, solely the energy used by the producer for respiration.
