What was Pangaea?when did it form and when did it break apart it was
Pangaea was a supercontinent. This enormous continent was consisted of all continental masses on Earth that merged together in the late Paleozoic era, around 335 million years ago. Pangaea lasted until the early Mesozoic era, breaking apart roughly around 175 million years ago. From the breaking apart of this supercontinent there were two large masses that formed, Laurasia on the north, and Gondwanaland on the south. As these two remnants of Pangaea continued to break apart, the modern day continents started to form and slowly started to give the planet the appearance that we see in the present.

What type of cell is prepared to live on its own?
A. Viral cell
B. Unicellular cell
C. Eukaryotic cell
D. Multicellular cell
Answer: A unicellular
Explanation: The entire body is unicellular therefore it can live on it's own
Final answer:
The type of cell that is prepared to live on its own is a unicellular cell (Option B).
Explanation:
Unicellular organisms are made up of a single cell that carries out all the functions necessary for life. In contrast, a eukaryotic cell (Option C) may be part of a multicellular organism and relies on a community of cells to survive. Viruses (Option A) are not considered living because they require a host cell to replicate. Multicellular cells (Option D) are individual cells that are part of a larger organism consisting of many cells, and they cannot live independently.
The presence of a membrane-enclosed nucleus is a characteristic of eukaryotic cells (Option B). Eukaryotic cells have membrane-bound organelles, including a nucleus, which differentiates them from prokaryotic cells which do not have a membrane-bound nucleus.
Lastly, a note on viruses: they are not considered living organisms as they are acellular, meaning they are not made up of cells. They are obligate parasites that require a host to replicate. Therefore, they cannot be categorized with cellular life such as unicellular or multicellular organisms.

Transcription occurs in the Nucleus of a eukaryotic cell
Transcription is the process of producing an RNA molecule from a DNA template within the nucleus of a eukaryotic cell.
Explanation:The goal of transcription is to produce a RNA molecule from a DNA template. Transcription occurs in the nucleus of a eukaryotic cell. In this process, the DNA unwinds allowing the RNA polymerase enzyme to attach to a specified sequence, known as the promoter. Once attached, it begins to build an RNA molecule, incorporating nucleotides that are complementary to the original DNA strand.

what is genetic equilibrium? what conditions are required to maintain genetic equiibrium?
The genetic equilibrium represents the condition of a genotype or an allele in the genetic pool of a particular population, where there are no changes in the frequency in the successive generations. This basically means that the population has managed to reach the peak of its evolution for the environment in which it leaves, so there's no evolutionary pressure for changes.
In order for the genetic equilibrium to be maintained for prolonged period of time, the population should not face any evolutionary pressure that will cause changes in it. In essence, this means that the environment in which the population lives should remain exactly the same as it is for longer period of time, so the population will have no need to change its appearance or behavior.

Dinoflagellates can perform photosynthesis and provide energy for themselves and for the coral that they live near. The coral provide protection to the dinoflagellates. This is an example of a
A. mutualistic relationship.
B. dependent relationship.
C. parasitic relationship.
D. commensalistic relationship.
Answer: A. mutualistic relationship.
Explanation:
Dinoflagellates are the algae which belongs to the family of Symbiodiniaceae. It is a single celled algae. It develops a mutualistic relationship with the coral polyps. The function of the dinoflagellates is the conduction of the process of photosynthesis. The products of photosynthesis are shared with the coral polyps which gives energy to the coral polyps to form calcium carbonate skeletons. The waste produced after this process in the form of inorganic nutrients and carbon dioxide is again utilized by the dinoflagellates. This way both species obtains the benefit. Hence, it is a mutualistic relationship between the two species.
The coral provide protection to the dinoflagellates. This is an example of a mutualistic relationship. The correct option is A.
The interaction between the dinoflagellates and the coral in this situation is an illustration of a mutualistic relationship.
Mutualism is a form of symbiotic partnership in which the interaction benefits both species.
In this instance, the dinoflagellates carry out photosynthesis and generate molecules that are high in energy, which serves as a source of nutrients and energy for both the dinoflagellates and the coral.
In exchange, the coral offers a safe habitat for dinoflagellates to flourish. It is a mutualistic connection since the life of both organisms depends on it and because both parties gain from it.
Thus, the correct option is A.

Maria has been making weather observations for the last couple of days. She made the following notes on the cloud coverage: "Monday: Sky is clear, no clouds. Tuesday: Sky is partly cloudy, large fluffy clouds".
Which understanding about the water cycle can help Maria explain the difference in the cloud coverage?
A. More water evaporated the land to form the clouds in Tuesday.
B. More water evaporated from the land to clear away the clouds on Monday
C. More water vapor condensed im the atmosphere on Tuesday to from the clouds.
D. More water vapor condensed in the atmosphere on Monday to clear away the clouds.
The correct answer to the problem is C. As I explained on your previous post, condensation is the leading cause of cloud formation.
The presence of large fluffy clouds on Tuesday compared to a clear sky on Monday is best explained by increased condensation of water vapor in the atmosphere on Tuesday, forming clouds.
The difference in cloud coverage that Maria observed on Monday and Tuesday can be explained by the water cycle. When Maria observed a clear sky with no clouds on Monday, it's likely there was less water vapor present in the atmosphere or that the conditions were not suitable for the water vapor to condense into clouds. On Tuesday, when she noted that the sky was partly cloudy with large fluffy clouds, this indicates there was likely more water vapor in the atmosphere that condensed to form the clouds. The most accurate explanation for the difference in cloud coverage is C. More water vapor condensed in the atmosphere on Tuesday to form the clouds.
how is modern earth different from earth over four billion years ago
Answer:
Earth was not habitable four billion years ago but now it is the only known planet that supports life.
Explanation:
Four billion years old earth was made up of dust and gases. It is claimed by scientists that the sources from which earth was formed included – a) Lunar rocks, b) Meteorites and c) Zircon crystal. The temperature of earth at that time was extremely high such that all the metals with in it were in molten state. Also there was no oxygen in the atmosphere. All these conditions made earth a non habitable planet.
But the present earth is a habitable planet with life on it that is dependent on its resources like air and water. Also the temperature of earth is much supportive to the existence of life on it.
