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.

which is true of the light reaction of photosynthesis
Hello There!
The correct answer is it produces "ATP"
Answer:
What is true of the light reaction of photosynthesis is that it produces ATP.
Explanation:
Photosynthesis is the conversion of inorganic matter to organic matter thanks to the energy provided by light. In this process the light energy is transformed into stable chemical energy, being the NADPH (nicotine adenine dinucleotide phosphate) and ATP (adenosine triphosphate) the first molecules in which this chemical energy is stored. Subsequently, the reducing power of NADPH and the energy potential of the phosphate group of ATP are used for the synthesis of carbohydrates from the reduction of carbon dioxide.

what type of cells are made from a secondary oocyte?
Answer:Ovarian
Explanation:
Answer: A secondary oocyte undergoes the second meiotic cell division to form a haploid ovum if it is fertilized by a sperm. Oogenesis begins with oogonia (singular, oogonium), which are the immature eggs that form in the ovaries before birth. Oogonia are diploid cells and are equivalent to spermatogonia in males.

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.

Sharon puts a large pot of water on the stove to boil pasta. Then she starts to make a tomato sauce. When the sauce is cooking, she looks at the pot of water and thinks the water level is much lower than it was. How does this diagram of part of the water cycle help Sharon explain what happened to the pasta water?
A .Energy from the stove heats the water, causing the water molecules to move faster and collide harder. This causes the water to change from liquid to gas.
B. As the water heats up, the water molecules begin to move faster and collide harder. This causes them to gain energy from the sun, and change from liquid to gas.
C. As the water heats up, the water molecules begin to move faster and collide harder. This causes them to release energy into the air, and change from gas to liquid.
D. Energy from the stove heats the water in the pot, causing the water molecules to move faster and collide harder, and eventually it causes the water to change from gas to liquid.
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 differences in the cloud coverage?
A .More water evaporated from the land to form the clouds on Tuesday.
B. More water evaporated from the land to clear away the clouds on Monday.
C. More water vapor condensed in the atmosphere on Tuesday to form the clouds.
D. More water vapor condensed in the atmosphere on Monday to clear away the clouds
Answer:
1. A
2. C
Explanation:
Hi again!
For the first question, we know that the water transformed into a gas. This fact eliminates choices C and D, primarily because they describe the change as "gas to liquid" instead of liquid to gas.
What separates B from A is that B is saying the liquid changed to a gas in response to sunlight, which is completely false and impertinent to the prompt.
A is the correct answer.
For the second question, we know that condensation causes clouds -- and that neither evaporation nor water vapor would clear clouds to make more of them, which eliminates choices B and D. Going back to condensation, the accumulation of water vapor plays a big role in the formation of clouds. While evaporation does play a part in [it] as well, condensation is what caused the sudden appearance of clouds in the troposphere.
C is the correct answer.
I hope I helped! :)
The diagram of the water cycle helps explain the evaporation of pasta water, while understanding the process of condensation in the water cycle can explain the differences in cloud coverage.
Explanation:The correct answer to the first question is A. Energy from the stove heats the water, causing the water molecules to move faster and collide harder. This causes the water to change from liquid to gas. When the water is heated, it evaporates and changes into water vapor, which is a gas. This is an example of the water cycle, where water goes through the processes of evaporation, condensation, and precipitation.
The correct answer to the second question is C. More water vapor condensed in the atmosphere on Tuesday to form the clouds. Clouds are formed when water vapor in the air condenses into tiny droplets or ice crystals. On Tuesday, more water vapor condensed in the atmosphere, resulting in the formation of clouds.

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.

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.
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.
