Why can bacteria quickly adapt to their environment whereas human take thousands of years?
Two reasons:
1- Bacteria are very simple simple celled organisms, which allows them to adapt quickly. In a changing environment, the bacteria don't have multiple organ systems to adapt.
2- Bacteria have very quick reproductive/division cycle. A generation for humans is typically defined as 20-25 years, whereas a bacterial generation can be as quick as hours to minutes. This means bacteria can reproduce exponentially overnight, while it could take humans hundreds of years to produce the same amount of offspring. This is important in terms of environmental adaptation. Say it takes 4 generations to adapt to a particular environmental threat; bacteria can accomplish this in under an hour, while humans could potentially take 100 years to adapt.

What is the difference between animals and bacteria?
!) Animals are multicellular and bacteria unicellular. 2) Animals are eukarotes whereas bacteria prokaryotes. 3) Bacteria can be autotrophs but anaimals are usually always heterotrophs. 4)Bacteria have cell wall and other coatings which animal cells lack 5) Bacteria lack membrane bound organelles which animals have. 6) Bacteria have ONE chromosome per cell whereas Animals can have more. 7) Bacteria divide by fission whereas Animal Cells divide by Mitosis and Meiosis.
What will happen after treating different types of bacteria with a Gram stain?
Some bacteria will appear purple, whereas other bacteria will appear red.
What 2 examples is a bacterial cell is different from an animal cell?
Bacteria typically have cell walls, whereas animal cells do not. Animal cells have a membrane bound nucleus, whereas bacteria have a non-bound nucleoid.
Does sugar kill bacteria?
the concentration of sugar in the bacteria is low whereas that of the outside, where the sugar is, is high. to make the concentration balanced, water molecules have to leave the cells of the bacteria therefore causing the bacteria to shrink and eventually die. (sorry if the answer is too long) this process is called "hypertonic"
Are protists bacteria?
No. Protists have nuclear membranes in their cells whereas bacteria do not.The kingdom Protists include bacteria. This kingdom includes other organisms besides bacteria. Just as we belong to the animal group.
Are people bacteria or germs?
Germs are any pathogenic (disease causing) microorganism. These might be bacteria, or they might be other things. Bacterial cells lack a nucleus. Humans are eukaryotes, whereas bacteria are prokaryotes. So people are not bacteria. People are multicellular, whereas germs are generally considered to be single celled orgamisms (most typically bacteria) or viruses. In that sense people are not germs either.
Compare and contrast bacteria and viruses?
Viruses are considerably smaller then bacteria. Instead of being a living cell able to undergo a life cycle on their own (bacteria can do this), they must take over the cell processes of another cell in order to reproduce. Viruses and bacteria are similar in that they both need a suitable environment to survive. Bacteria and viruses are both pathogenic (disease causing) to humans. Bacteria are killed by antibiotics. While viruses are not.
What is a word for bacteria?
Bacteria, by definition, is single-celled. Some bacteria, however, contains organelles and some doesn't. Bacteria without organelles is called prokaryotic, whereas bacteria with organelles is eukaryotic.
Why bacteria is grow in labortary if its ubiquitous in nature?
Bacteria can grow in the laboratory because the conditions provided are optimal for their growth, such as a nutrient-rich environment, suitable temperature, and pH levels. In nature, bacteria may face competing organisms or adverse conditions that limit their growth, whereas in the laboratory, these limiting factors are controlled or removed.
Does the climate effect decomposition?
Hypothermia slows bacterial growth and reproduction. Since bacteria are generally the prime agents of decomposition, hypothermia tends to slow the process. This is why we refrigerate our food.
Differences between bacteria and virus?
Bacteria are single-celled organisms that can reproduce on their own, while viruses are not cells and rely on a host cell to reproduce. Bacteria are larger in size than viruses and can be treated with antibiotics, whereas viruses are smaller and are typically treated with antiviral medication. Bacteria are living organisms with their own cellular machinery, whereas viruses are considered non-living as they require a host cell to replicate.
Why do Bacteria differ from viruses because bacteria have?
Bacteria are single-celled organisms that can live independently and reproduce by dividing, whereas viruses are acellular particles that require a host cell to replicate. Bacteria have a cellular structure with organelles like a cell membrane and ribosomes, while viruses consist of genetic material (DNA or RNA) encased in a protein coat. Additionally, bacteria can be killed by antibiotics, whereas viruses are not affected by antibiotics and require antiviral medications.
