A freshwater and salt-water biome refers to the body of water (aquatic biome) that makes up about 75 percent of the surface of planet Earth.
The freshwater biome is divided into three (3) major levels or zones and these include:
1. Littoral zone: it is the shore area of a freshwater and it can either be very wide or very narrow.
Some examples of organisms found in the littoral zone are:
2. Limnetic zone: it is the open water area of a freshwater.
Some examples of organisms found in the limnetic zone are:
3. Profundal zone: it is the bottom and deep water area of a freshwater.
Some examples of organisms found in the profundal zone are:
On the other hand, a salt-water biome is divided into four (4) major levels or zones and these include:
1. Intertidal zone: it comprises these organisms;
2. Pelagic zone: it comprises these organisms;
3. Abyssal zone: it comprises these organisms;
4. Benthic zone: it comprises these organisms;

Eukaryotes have a cell wall.
Prokaryotes do not have a membrane-bound nucleus.
Eukaryotes copy DNA and are able to reproduce.
Prokaryotes cannot live without a host.
Prokaryotes, such as bacteria and archaea, lack a membrane-bound nucleus and other internal membrane-bound organelles, while eukaryotes, including animal, plant, and fungal cells, have a nucleus surrounded by a nuclear membrane and contain multiple internal membrane-bound organelles.
The main difference between Eukaryotes vs Prokaryotes pertains to their cell structure.
Prokaryotes, such as bacteria and archaea, do not have a membrane-bound nucleus where their genetic material is housed.
Instead, their DNA is located within a region known as a nucleoid.
These cells also typically lack other types of membrane-bound organelles.
On the other hand, eukaryotes, including animal, plant, and fungal cells, have a nucleus enclosed by a complex nuclear membrane, and this nucleus contains the cell's DNA.
Eukaryotes also have other internal membrane-bound organelles, giving it additional complexity.
This key structural difference significantly impacts how these cell types operate and interact.

Answer:
Explanation:
Prokaryotes have are simple celled and do not have a nucleus while eukaryotes are more complexed and have a nucleus.
It is the external part of the female genital organs.
It is the birth canal of the female reproductive system.
It is the organ in the female that carries the egg to the uterus.
The vulva is the external part of the female genital organs.
"Offspring grows" is a phrase commonly used to refer to the development of a fetus during pregnancy.
It means that the embryo, which is the early stage of development of the fertilized egg, undergoes a series of cellular divisions and differentiation processes, eventually forming a fully-formed baby.
The growth of the offspring is a complex and highly regulated process that involves many different biological systems and processes, including the placenta, umbilical cord, and various hormones and signaling molecules.
The growth and development of the offspring is a critical aspect of reproduction, and is essential for the continuation of the species.

Answer:
messenger RNA
Explanation:
Answer:
messenger RNA (mRNA)
Explanation:
mRNA is responsible for transcribing the bases of DNA into a blueprint for making proteins
Answer:
The complete question includes a chart which I'm including below:
Which mutants are in the same complementation group as mutant strain 1?
of course: ("+" indicates that complementation was observed)
,,,and the answer regarding which mutants are in the same complementation group as mutan strain 1 are: 2,4, & 7.
The mutated DNA is TAC CTC ACT GAG CGT.
What is the impact of this particular mutation on the organism? In order to find out, you need to transcribe and translate the codons.
Answer:
The mutation that involves the change in the sequence of DNA bases is reflected both in the transcription of mRNA and in translation, giving rise to an alteration in the protein, which may not function and whose impact on the organism is a morphological or functional alteration.
Explanation:
According to this scenario, the DNA has experienced a mutation by changing the sequence by one of its bases, Cytosine by Thymine, producing in the mRNA a termination codon that interrupts the normal synthesis of the protein, preventing that protein from fulfilling its function. This particular mutation is called Nonsense mutation.
For normal DNA
DNA TAC CTC ACC GAG CGT
mRNA AUG GAG UGG CUC GCA
Protein Met - Glu - Trp - Leu - Ala
For the mutated DNA
DNA TAC CTC ACT GAG CGT
mRNA AUG GAG UGA CUC GCA
Protein Met - Glu - STOP - Leu - Ala
The change of a cytosine by Thymine in the mutated DNA produces that the third codon of the mRNA is altered, encoding a UGA termination codon, which prematurely stops the protein synthesis and originates an incomplete protein, probably not functional, whose impact in the organism is a morphological or functional alteration.
The correct answer is - B) more; in total.
The urban areas use much more energy than the rural areas, by far. The reasons for that are numerous, with the two biggest being the number of people and the industry.
The number of people living in urban areas is higher than the number of people living in rural areas. Also, the people in the urban areas use much more energy because they rely on much more technology, technology that uses energy in order to work.
Most of the industry is also located in and around the urban places. The industry is a huge consumer of energy, thus increasing the usage of energy further more.
