Answer:

Yes.

Explanation:

Yes, a tree is falling over in a forest make a sound because both the tree and ground are hard surfaces which can produces sound by contact physically with each other. For testing this hypothesis, we have to take a tree and cut that tree. when the tree falls on the ground it will definitely produces sounds by contact physically with the ground when falls with a large force.

A) Explain why antibiotics would kill a prokaryotic cell. (2 points)

lisov135 [29]

Answer:

Antibiotics are simply chemicals that kill prokaryotic cells but do not harm eukaryotic cells. They are natural chemicals produced by fungi and bacteria that act to control their bacterial competitors. For example, streptomycin stops protein synthesis in prokaryotic cells by binding to their unusual ribosomes.

Explanation:

Sorry if this makes no sense. Basically, the antibiotics will harm/kill cells like the prokaryotic cell, but it won't harm or kill any human cells that are essential. They'll kill bacteria, though. The chemicals in the antibiotics aren't compatible with the ones in the prokaryotic cell, so it'll kill it.

If the changes are maintained as a result of stimulus, the effect is: a. Homeostasis b. Feedback response c. Negative feedback r

Volgvan

Answer:

b. Feedback response

Explanation:

Homeostasis is the ability of the system to preserve a constant state despite external inputs. Homeostasis requires the constant monitoring of internal environmental conditions in order to keep the balance of the system. Conversely, a feedback response enables to maintain a change observed in the internal conditions of a given system (for example, a living organism). This change is regulated by the interaction among different elements in the system including effectors, sensors and stimuli, which work together to maintain the feedback state.

A researcher was studying mutations in bacteria. He found that certain bacteria had changes in their DNA that allowed them to be resistant to antibiotics. This research is an example of evolutionary genetics. The mutation will lead to all the bacteria becoming resistant to the antibiotic.

Genetic evolution :

Evolutionary genetics examines the relationship between genetic variation and evolutionary change. As a result of the recent expansion in the availability of whole genome sequence data, large amounts of genetic data are being produced at an increasing rate, making programming an indispensable tool for researchers.

The spread of antibiotic resistance among pathogenic bacteria is a straightforward and elegant example of adaptation through natural selection. Through mutations that alter the biological targets of antibiotics or by obtaining resistance genes from other bacteria, microorganisms can develop resistance to antibiotics.
