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.

The growth of bacteria is determined not only by the composition of their surroundings but also by sudden changes in the living environment. For rapid growth in different environments, bacteria need to adjust their enzyme levels in order to rapidly benefit from the nutrients currently available in their surroundings. If the living environment undergoes rapid changes, the bacterium’s own production of proteins has to conform to these changes in an effective way. How are bacteria able to adapt to a rapidly changing environment?
Answer:
Bacterial genes are organized into clusters of coregulated genes, that are regulated such that they are all turned on or off together.
(hope this helps)
Answer:
Bacteria can adapt to environmental changes thanks to their effective mechanism for regulating gene expression, that is, mechanisms that bacteria have effective mechanisms to control which genes are expressed and at what levels. Bacteria have specific regulatory molecules that control whether a particular gene will be transcribed into the mRNA. These molecules act by binding to DNA near the gene and help or block the transcription enzyme, RNA polymerase. Operons are very important in bacteria because operons allow the cell to efficiently express the groups of genes whose products are needed at the same time.

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.

One important abiotic factor in marine ecosystems is the a. amount of plankton. c. kinds of algae. b. water depth. d. size of animals. Please select the best answer from the choices provided
Answer:
b. water depth
Explanation:
The abiotic factors are the factors that are not part of the biosphere, thus they are not living organisms. In this case, the water depth is that type of factor that would influence the marine ecosystems. The depth of the water is crucial for the type of organisms that can exist in it, their density, and diversity. This is because the water has certain characteristics that provide certain conditions, like if the water is shallow, it will be warmer, but if its deep, then it will be colder. The amount of nutrients in it also depends on the depth. The sunlight can penetrate into the water only in the shallow parts, but not in the deep ones, so the basis of the ecosystems, the producers can exist only where they can have sunlight to perform the process of photosynthesis.
Water depth is an important abiotic factor in marine ecosystems, as it influences the distribution and abundance of marine organisms.
Explanation:One important abiotic factor in marine ecosystems is the water depth. Water depth plays a crucial role in determining the distribution and abundance of marine organisms. Different depths provide varying levels of light, temperature, and pressure, which in turn influence the types of organisms that can survive in a particular marine zone.

1. Name TWO contributions made by soil organic matter to the environment.
2. What happens to the pH of the ocean seawater as carbon dioxide dissolves into it?
3. Give TWO relationships between greenhouse gases and heat radiation that negatively affect the globe.
Answer:
1) Binds soil particles into aggregates and improves the water holding capacity of soil.
2) When carbon dioxide dissolves in seawater, most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH.
3) Carbon dioxide (CO2) and other greenhouse gases act like a blanket, absorbing IR radiation and preventing it from escaping into outer space. The net effect is the gradual heating of Earth's atmosphere and surface, a process known as global warming.
Without greenhouse gases in its atmosphere , the Earth would be much colder on average than it is now. Greenhouse gases: absorb energy transferred as infrared radiation from the Earth's surface. release infrared radiation in all directions, which keeps the Earth warm.

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.
