es used by two farmers to protect the corn crop are described below.
Technique A: Sprayed his corn crop with an insecticide. The insecticide is known to kill all honeybee, butterfly, and moth larvae.
Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn.
Which technique is likely to have less of an impact on the environment?
Technique B because it preserves the harmless insects and targets only the moth larvae


Technique A because insecticide use is better for preserving the environment

Technique B because it may help humans who consume corn to fight bacA genetically engineered corn plant is approved for agricultural use.

Which type of bond exemplifies a weak chemical bond? covalent bonds in solution hydrogen bonds in solution ionic bonds in solids
vova2212 [387]

Covalent bonds in solution, hydrogen bonds in solution, ionic bonds in solids, nonpolar covalent bonds in solids- the weakest bond is hydrogen bond.

What is a chemical bond?

A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. In covalent bonds, the electrons are shared, whereas in ionic bonds, the electrostatic attraction of two ions with opposing charges forms the link. Strong bonds, also known as primary bonds, include covalent, ionic, and metallic ties. Weak bonds, also known as secondary bonds, include dipole-dipole interactions, the London dispersion force, and hydrogen bonds.

Since there is no necessity for an electron exchange during formation, the hydrogen bond is weak. As a result, it is simpler to break apart a hydrogen connection between two molecules.

Which scale is never used by scientists?
alukav5142 [94]

in a brewery, someone accidentally leaves cracked open the top of a beer fermentation container. what is the most likely outcome
Anna71 [15]

If someone accidentally leaves cracked open the top of a beer fermentation container, there is a possibility of the yeast cells breaking down in the beer and releasing some contents of cells in the beer. This process is known as autolysis.

When energy is extracted from carbohydrates in the absence of oxygen, fermentation occurs.

Fermentation also involves the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms creating sort of an effervescence leading to the generation of heat

From the question, if someone accidentally leaves cracked open the top of a beer fermentation container, there is a possibility of the yeast cells breaking down in the beer and releasing some contents of cells in the beer. This process is known as autolysis.
