What is the main characteristic of the bacteria domain?All living things are classified into kingdoms based on specific characteristics found in organisms in that kingdom.
For the bacteria kingdom, the main characteristic present is that they lack a well defined nucleus as well as nuclear membrane.
Organisms without a well-defined nucleus are known as prokaryoytes.
Thus, the main characteristics of the bacteria domain is that they lack a well-defined nucleus and are known as prokaryotes.

offspring.
Answer: During gamete formation, the alleles for each gene segregate from each other, so that each gamete carries only one allele for each gene. an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles.
What are genes?
Genes are an basic physical and functional unit of heredity.Genes are what make our DNA.

A hurricane passes through the Gulf of Mexico and destroys many of the coastal regions of Northwest Florida,
Which of the following is a likely impact of this catastrophic event on biodiversity?
Species brought in by the storm surge will displace species native to the coastal wetlands.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of
habitat.
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity
will increase in these areas.
Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the
local species, causing a decrease in biodiversity
Answer:
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of
habitat.

What is meant by "concentration"? How can you increase the concentration of salt (electrolytes) in a solution of water? How can you decrease the concentration of electrolytes in a solution?
Answer:
See the answer below
Explanation:
The concentration of a solution refers to the amount of solute that is dissolved in a particular amount of solvent.
In order to increase the concentration of salt in a solution of water, more solute (that is, the salt) would be required to be added to a fixed volume of the solution. The more the amount of the salt added, the more the concentration of the solution provided the volume remains constant.
In order to decrease the concentration of electrolytes in a solution, more solvent would be required to be added to the electrolyte while keeping the dissolved solute constant. The more the added solvent, the lower the concentration as long as the amount of solute dissolved remains constant.

What best describes the role of photosynthesis and respiration in the carbon cycle?
Answer:
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
Explanation:
Please mark me as brainlist
Photosynthesis removes carbon from the atmosphere, respiration adds carbon to the atmosphere.
What is photosynthesis?Photosynthesis is defined as the process through which plants convert carbon dioxide, water, and sunshine into oxygen and sugar for energy.
It can also be defined as a method used by plants and other living things to change light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
Through photosynthesis, plants transport carbon from the atmosphere into the biosphere and up the food chain. They use solar energy to chemically combine carbon dioxide, oxygen, and hydrogen from water to create sugar molecules.
Photosynthesis is primarily used to convert solar energy into chemical energy, which is then stored for use at a later time.
Thus, photosynthesis removes carbon from the atmosphere, respiration adds carbon to the atmosphere.

What biotic and abiotic factors influence the flow of matter and energy in different biomes
Answer:
Temperature, water and nutrients.
Explanation:
Biotic factor refer to the living component of the ecosystem. Plants and animals.
Abiotic factor refer to the nonliving component of the ecosystem such as light, temperature e.t.c.
Biomes refers to group of terrestrial ecosystems on the earth.
Therefore, the following factors affect biomes
Water: water can affect biomes in the sense that too much of it can lead to flood, thereby leading to loss of plants and animals. Decrease of it can lead to famine which also can lead to loss of biomes.
Temperature: The best temperature should be optimum temperature. An increase or decrease in temperature have negative effect on biomes which can lead to low vegetation, dehydration, inactiveness of animals.
Nutrients: nutrients availability can lead to increase in plants growth. Vegetation will increase if there is adequate nutrients supply but if there is low nutrients there will be reduced growth.
Therefore, temperature, nutrients and water is important for biomes.

Explanation:
A model answer for translation is always this:
mRNA leaves the nucleus via the nuclear pores and travels to a ribosome (in the cytoplasm or on the rough endoplasmic reticulum)
The ribosome attaches to the start codon on the mRNA.
A tRNA molecule with an anticodon complementary to the start codon on the mRNA carries a specific amino acid to the ribosome and lines up against the mRNA codon.
This is repeated, and each tRNA molecule transports a unique amino acid to the ribosome until the stop codon on the mRNA strand is reached.
As the ribosome moves along the mRNA strand, peptide bonds form between the adjacent amino acids, forming a polypeptide chain.
This chain detaches from the ribosome and will undergo folding to become a specific type of protein.
Hope this helps you to understand the process a little better! :)
