Explain why Gram-negative bacteria are more resistant to biocides than Gram-positive bacteria. Be specific and descriptive in your response. A description of the differences between Gram-negative and Gram-positive bacteria should be included, along with an explanation of why any of those differences would have anything to do with the actions of biocides.

Explanation:

Gram positive and gram negative bacteria differ in their cell walls.  gram positive bacteria have a thick peptidoglycan layer and an outer membrane protect the gram negative against many antibiotics that could otherwise damage the peptidoglycan layer or inner cell.

the answer for this question would be d. glaciers

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
