All of the organisms in the domain Archaea are prokaryotes.
Archaea are unicellular organisms with no nuclei, hence are prokaryotes.
Characteristics of Archaea Greek word Archaios means ancient.They are unicellular organisms that resemble bacteria and have some similarity to eukaryotes.Hence a third domain Archaea was introduced by Carl Woese based on ribosomal RNA analysis.They can live in extreme conditions like higher temperature, higher cold regions etc.To learn more about prokaryotes :

how many codons specify 5 amino acids?
Answer:
20, Im not completely sure tho
Explanation:
what are the two main types of chemical bonds?
Answer:
Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.
Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.
Hope it helps!!!
Answer:
the two main types of chemical bonds are:
ionic bonds and covalent bonds.
If 22% of a DNA sample is made up of cytosine, C, what percentage of the sample is made up of adenine,
A?
Answer:
28% of Adenine
Explanation:
Chargaff's Rule states that A = T and C = G
Because of that, the sample must have the equation:
A + C = T + G
G must have the same amount as C so,
A + .22 = T + .22
Both sides of the equation must equal each other by .50, so .50 - .22 = .28
.28 x 100 = 28%
If 22% of a DNA sample is made up of cytosine, C, the percentage of the sample is made up of adenine, A is 28%
What is DNA?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.
DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are the same.

Explanation:
hope this helps :)
A spore grows into a mature gamete producing plant is best describe the life cycle of fern.
What is the life cycle of fern?The life cycle of the fern has two different stages such as sporophyte and gametophyte. The sporophyte stage which releases spores whereas gametophyte stage which releases gametes. Gametophyte plants are haploid whereas sporophyte plants diploid. This type of life cycle is known as alternation of generations.
So we can conclude that a spore grows into a mature gamete producing plant is best describe the life cycle of fern.

Deforestation leads to environmental imbalance. Give reason.
Answer: Well, deforestation is cutting down trees, and many arboreal animals live in those trees. So if they have no proper shelter, they would have no place for personal activities such as breeding, feeding etc. And without those important activities that they have to do everyday, the population of arboreal animals will keep on decreasing until they go extinct. Though that's not the only problem. The herbivores won't get anything to eat, hence not letting the omnivores or carnivores get their food. As you can see, deforestation can create a huge environmental imbalance.

I attached an image to my question.
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.

Here are the options.
a. Wood is routinely recycled to make new wood-based products.
b. Wood products can be manufactured from different tree species.
Eliminate
c. Wood may be replenished by planting new trees to replace those being used.
d. Wood products can be manufactured using various other materials such as plastics.
The correct option is c.
Wood may be replenished by planting new trees to replace those being used.
Explanation:
This is because wood is a Renewable resource because Renewable resources are resources that can be replenish or reproduce again after usage either by naturally producing another one. Theses resources are not exhausted because they can naturally be reproduce again. Wood is a Renewable resources because new ones are planted to replaced the used ones.
Over the next 10 years, many of the UK’s nuclear power stations are expected to close.
Suggest how this may affect the future balance of sources of energy used for electricity production in the UK.
Answer:
Greatly affected.
Explanation:
This closing of nuclear power stations greatly affect the future balance of sources of energy used for electricity production in the UK because the burden of production comes on other sources such as production of electricity from fossil fuels, wind and solar radiation etc. If electricity is produced from fossil fuels so it leads to pollution of the environment whereas if the electricity is produced from wind and solar radiation, it is very costly but good for the environment.

Answer:
Cause: Earth’s magnetosphere traps radioactive solar wind particles in bands around Earth → Space travel through the Van Allen belts is dangerous.
Cause: Earth is surrounded by a magnetic field → Effect: Solar wind deflects toward the poles.
Cause: Solar wind particles interact with Earth’s upper atmosphere → Effect: An aurora is created
Explanation:
I have been able to drag the tiles to the correct boxes to complete the pairs.
When there is a trapping of radioactive solar wind particles in bands by the earth's magnetosphere, it becomes dangerous to travel in space through the Van Allen. Cosmic rays and solar particle add up to the additional hazards that it poses. A Van Allen radiation belt is known to be a zone where energetic charged particles are found. Most of the energetic charged particles originate from the solar wind. The solar wind are captured by and held around a planet by that planet's magnetic field.
When the solar wind interacts with the earth's atmosphere, there is a collision of atoms of oxygen and nitrogen from the earth's atmosphere. The energy that is formed is a colorful glowing halo which is known as an aurora.
Answer:
Cause: Earth’s magnetosphere traps radioactive
solar wind particles in bands around Earth.
