I had taken the test just now and got it right for which the answer is spores. Because they take place in sexual and asexual reproduction. Hope this helps. Have a great day! please can you mark me brainliest :)
Sorry I am like 2 years late lol
False
I believe the answer is true plz mark brainliest if correct
Eubacteria, unlike Archaea, generally live in less extreme environments. They are unicellular, prokaryotic, lack nuclei, and unlike many Archaea, cannot live without oxygen.
Organisms in the Kingdom Eubacteria, also known as the domain Bacteria, are unicellular prokaryotic organisms without nuclei.
Compared to organisms in the domain Archaea, which often thrive in extreme environments, organisms in Kingdom Eubacteria generally live in less extreme environments, making option 'B' the correct answer to your question.
They are found in variety of habitats and can adapt to a broad range of conditions, but they do not typically favor the same harsh, extreme environments that many Archaea do.
They also lack the adaptation to live without oxygen seen in some prokaryotes, like certain Archaea.

In 1983 a hospital-acquired intestinal infection caused by the bacterium Enterococcus faecium joined the list of bacteria that could not be killed by penicillin.
Which of these BEST describes why certain bacteria have become resistant to penicillin?
A) The penicillin in the 1970's was much weaker that the penicillin used today, thus it was not as effective.
B) Penicillin was not effective in treating any bacterial diseases, so the doctors had to find new treatments.
C) These new bacterial strains came out of the jungles and forests already equipped to be penicillin-resistant.
D) Penicillin was so heavily prescribed by doctors that it led to certain, more fit, strains of bacteria to be able to survive.
2)
I think B but i’m not for sure
Answer:
D. Penicillin was so heavily prescribed by doctors that it led to certain, more fit, strains of bacteria to be able to survive.
Explanation:
Researchers thought penicillin was the cure for all, and thus it became overused. Through natural selection, new, stronger strains of bacteria developed.
Hershey and chase have concluded that DNA is not protein it was the genetic material.
Explanation:
Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.
The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.
The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.
They would have concluded that the protein coat also entered the bacterial cell and could not deduce that protein is the genetic material.
Explanation:
In their experiment, Hershey and chase found that all the DNA coated with 32 p were missing from the solution as bacteriophage after adsorption on bacterial cell their DNA was transferred to the bacterial cell. The presence of 32 S in the solution shows that the protein coat does not enter the cell during infection.
This way they concluded that DNA is the genetic material and not the protein.
Since phage infecting bacteria inserted their DNA into it and got replicated increasing their number. Also, protein is not involved in their growing numbers.
