The ____ is a major group of Archaea that do not have cell walls, has an S-layer, can be square shaped and have intricate networks between the cells

A) Crenarchaeota B) Euryarchaeota C) Nanoarchaeota D) Korarchaeota

The ______ is a group of Archaea that have rigid cell walls made of pseuedopeptidoglycan, glycans, and glycoproteins
A) Crenarchaeota B) Euryarchaeota C) Nanoarchaeota D) Korarchaeota

Which of the following convert atmospheric nitrogen into NH3?
A) Certain types of archaea B) Certain types of bacteria C) Certain types of plants D) Certain types of archaea, bacteria, and plants E) Certain types of archaea and bacteria

To answer these questions, we can use our knowledge of microbiology and the characteristics of different organisms. Let's break down each question and determine the correct answer:

Question 1:
The options provided are A) Crenarchaeota, B) Euryarchaeota, C) Nanoarchaeota, and D) Korarchaeota. We are looking for a major group of Archaea that do not have cell walls, have an S-layer, can be square-shaped, and have intricate networks between the cells. To find the answer, we should consider the characteristics of each group:
- Crenarchaeota: This group includes thermophilic Archaea and does not match the given characteristics.
- Euryarchaeota: This group includes methanogens, halophiles, and thermophiles, but does not match the given characteristics.
- Nanoarchaeota: This group includes tiny parasitic Archaea, but does not match the given characteristics.
- Korarchaeota: This group includes hyperthermophiles, and their characteristics do not match the given ones either.

None of the options A, B, C, or D correspond to the characteristics mentioned. Therefore, there may be a mistake or missing information in the question. It is not possible to provide a correct answer based on the given options.

Question 2:
The options provided are A) Crenarchaeota, B) Euryarchaeota, C) Nanoarchaeota, and D) Korarchaeota. We are looking for a group of Archaea that have rigid cell walls made of pseudo-peptidoglycan, glycans, and glycoproteins. Let's go through the options to find the correct one:
- Crenarchaeota: This group does not match the given characteristics.
- Euryarchaeota: This group also does not match the given characteristics.
- Nanoarchaeota: This group does not match the given characteristics either.
- Korarchaeota: This group does not match the given characteristics.

Again, none of the options A, B, C, or D correspond to the given characteristics, so it is not possible to provide a correct answer based on the given options.

Question 3:
We are looking for the organism(s) that convert atmospheric nitrogen into NH3. The options provided are A) Certain types of archaea, B) Certain types of bacteria, C) Certain types of plants, D) Certain types of archaea, bacteria, and plants, and E) Certain types of archaea and bacteria. To find the correct answer, we need to consider which organisms are capable of nitrogen fixation (converting atmospheric nitrogen into a usable form).
- Certain types of archaea: Some archaea, such as nitrogen-fixing methanogens, are capable of nitrogen fixation.
- Certain types of bacteria: Certain bacteria, such as Rhizobium or Azotobacter species, are known nitrogen fixers.
- Certain types of plants: Some plants, such as legumes and certain species of trees, have a symbiotic relationship with nitrogen-fixing bacteria in their root nodules, allowing them to fix nitrogen.
- Certain types of archaea, bacteria, and plants: This option includes all the organisms mentioned above and is also correct since it encompasses all known nitrogen-fixing organisms.
- Certain types of archaea and bacteria: This option is also correct since it includes all nitrogen-fixing archaea and bacteria.

Therefore, the answer to the third question is D) Certain types of archaea, bacteria, and plants, or E) Certain types of archaea and bacteria.

In summary, due to the lack of appropriate options for the first two questions, it is not possible to determine the correct answers. However, for the third question, the answer is D) Certain types of archaea, bacteria, and plants, or E) Certain types of archaea and bacteria.
