which of the following statements describes areas of research for uses of bacteria in biotechnology?

Question

bacteria are being studied in order to determine a way to eliminate all bacteria.
bacteria are being studied in order to find ways to increase antibiotic resistance.
bacteria are being studied to produce vaccines and biodegradable plastics.
bacteria are being studied to eliminate genetic engineering practices.

Which of the following is a goal of future bioengineering efforts?
farmers may one day be able to use selective breeding in agriculture.
scientists hope to reduce the ability of humans to be recognizable with technology scanning.
scientists hope to one day be able to reduce biodiversity in organisms.
artificial limbs could be created in order to replace those tissues when they are injured or stop functioning properly.

how can bacteria become resistant to antibiotics?
antibiotics are only effective for a short amount of time and have a limited shelf life, so bacteria can become resistant to them over time.
bacteria that have resistant genes pass them on to future generations that carry mutations that lessen the effectiveness of the antibiotics.
antibiotics have only been used in a limited way among animals and humans, allowing the limited exposure to bacteria to cause them to be resistant.
bacteria have very little variations in their genetic material from one generation to the next allowing them to withstand greater doses of antibiotics.
