Biological pest control methods supplement but cannot replace chemical pest control methods.t/f

Answers

Answer 1

Answer: This is false. Farmers of organic food have been doing this for a whileand it has become a trend. Food grown this way is usually a lot moreexpensive but the evidence that the food made in this manner ishealthier still up for debate as inconclusive results have been found,pointing out that there's really not that much of a difference.

Answer 2

Answer:

Answer:

False

Explanation:

Biological pest control methods are used to control the population of pest below a level where it cannot damage the crops. Instead of using chemicals (which lower the soil quality), living organisms (which are predator, parasite, herbivore etc.) are introduced in the crop field to keep a check on population of damaging pest or weeds

This is an organic method of gardening where a beneficial organism is chosen to control the harmful pest

Hence, given statement is false

true

The biogeochemical cycles move through mainly the biotic and abiotic components of the earth, more elaborately the spheres -biospheres, lithosphere, hydrosphere and atmosphere regions of the ecosystem. These biogeochemical cycles, from its terminology and discernable word morphology- involves the biological, geological and chemical components that make out to complete an exact and purposed cycle. The purpose in these cycles are to maintain balance and to ensure the ongoing process of the living and non-living organisms in the environment. These cycles’ help to living organisms survive and thrive. One popular example is the water cycle.

Create a sentence explaining how amino acids form proteins.

Answers

Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

Sample answer: Amino acids are monomers that combine to form polymers called proteins.
