Predict what will happen to an abandoned strip mine over time.
Answer:
An abandoned strip mine will partially recover over time. Without human intervention, however, its recovery will be minimal.
Explanation:
Mines that have been abandoned or are no longer in operation were often locations of highly developed exploration, mining, or mine production. Rehabilitation programs typically need large financial investments.
What is an abandoned strip mine?The soil will lose its fertility after the mining process since only the parent rock will remain at the bottom and organic stuff will be lost.
Soil erosion will occur as a result of the soil becoming loose. In strip mining, the site might be partially reclaimed but not restored to its previous state.
A narrow strip of overburden (earth or dirt) is removed from above a desired deposit, the removed overburden is dumped behind the deposit, and then the desired deposit is extracted. This process is known as strip mining.
Therefore, a strip mine that has been abandoned will partially recover.

Select a statement that is not correct about bacterial fimbriae?
A.they protect the cell from dehydration
B. they are called attachment pili to distinguish them from the pili used to transfer DNA during conjugation
C.they are used to attach the cell to its substrate or to other prokaryote
D. they are hair-like projections that aid in attachment.
Answer:
About bacterial fimbriae, the statement that is not correct is that they protect the cell from dehydration.
Explanation:
Bacterial fimbriae are extensions of the cytoplasmic membrane, predominantly of a protein nature, which give the bacteria the ability to adhere to surfaces, tissues or other bacteria.
These pilous structures can be present in all bacteria, constituting a factor related to their infectious capacity. The main function of fimbriae is adhesion, so they do not constitute a protective element against dehydration.
The other options correspond to true characteristics of the bacterial fimbriae.

Hello. This question is incomplete. The full question is:
What factor will most likely decrease the rate of glucose production?
A. decreasing in availability of oxygen B. decreasing in availability of carbon dioxide C. increase in availability of water D. decrease in plant-eating organisms
Answer:
B. decreasing in availability of carbon dioxide
Explanation:
According to the answer options, we can say that this question is related to the formation of glucose through photosynthesis, which is the process that uses carbon dioxide and water to generate glucose. In this case, we can confirm that for the photosynthesis process to occur fully and the plant to achieve a large glucose production, a large availability of water and a large availability of carbon dioxide are required.
Therefore, we can conclude that a decrease in the availability of carbon dioxide would decrease the production of glucose.

What are the three criteria that an object has to meet in order to be considered a planet?
Answer:
1. Must orbit around a star
2. Must be close to/a sphere shape
3. Must have been proven to finish it's orbit around a star.
Explanation:
These are the main 3 requirements for something to be a planet.
Planets must do three things: Must orbit a star (in our cosmic neighborhood, the Sun). It must be big enough to be gravitationally spherical. Its gravity must have removed similar-sized particles from its orbit around the Sun.
What is a planet?When gas and dust particles collide and stick together as they orbit a star, planets are created. Because the star's wind blows away their gases and because they are made of heavier materials that are drawn to the star by gravity, the planets closest to the star tend to be rockier.
It states that a planet must fulfill these three requirements: It must follow the orbit of a star (in our cosmic neighborhood, the Sun). It needs to be of sufficient size for there to be sufficient gravity to mold it into a spherical shape. It must be of sufficient size that its gravity drove away any other objects in the vicinity of its orbit around the Sun that were of a comparable size.

what are the factors affecting photosynthesis ?
The process in which autotrophs convert light energy into chemical energy, and prepare their food.
This chemical energy is created from water and carbon dioxide and stored as a sugar molecule.
Photosynthesis occur in chloroplasts where the pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll use sunlight and synthesize nutrients by using carbon dioxide, water and sunlight.
several factors influence photosynthesis such as increase in light intensity causes higher rate of photosynthesis.
Higher concentration of carbon dioxide increases the rate of photosynthesis, range of CO2 needed is 300 – 400 PPM for photosynthesis.
Temperature should be in range between 25° to 35° C.

Which two spheres affect the water cycle the most?
Answer:
All of the liquid water on Earth, both fresh and salt, makes up the hydrosphere, but it is also part of other spheres. For instance, water vapor in the atmosphere is also considered to be part of the hydrosphere. Ice, being frozen water, is part of the hydrosphere, but it is given its own name, the cryosphere.
The water cycle has been an important biogeochemical cycle that involves the movement of the water. The water cycle involves the atmosphere and the hydrosphere.
What is the water cycle?The water cycle has been the transportation of the water that moves through the various spheres so to move the various phases of water on the earth. Water has been crucial for the survival and living of organisms.
This hydrologic cycle continuously moves the water above and below the earth's surfaces. It involves the movement of the water in the atmosphere and the hydrosphere of the earth. The hydrosphere has been constituted of water and includes oceans, seas, rivers, lakes, etc.
The water from the hydrosphere gets evaporated under the sun and gets converted into water vapor that rises due to less dense and rises into the atmosphere. The atmosphere is above the earth's surface which includes the sky and clouds where the evaporated water gets condensed into droplets that fall in the form of a precipitate.
Therefore, the atmosphere and hydrosphere are involved in the water cycle.

When is it appropriate to use a line graph, bar graph and a pie chart?
Answer:
When your graphing to data from an experiment.
Explanation:
You use any type of graph when you're doing an experiment because, in the beginning, you start by marking where you started then as time goes on you mark it accordingly. For example, say your starting at 5cm on a plant so on the line/bar graph you make 0 you 5 since that is where you're starting at. when you water the plant you decide to give it 10cm of water and put it in the sun constantly. A week later of sun and water it grew 10cm, so you mark it on your line/bar graph to show how much it grew over time. Make a little bit more sense?

Who Is Thomas Malthus?
Thomas Robert Malthus was a famous 18th-century British economist known for the population growth philosophies outlined in his 1798 book "An Essay on the Principle of Population." In it, Malthus theorized that populations would continue expanding until growth is stopped or reversed by disease, famine, war, or calamity. He is also known for developing an exponential formula used to forecast population growth, which is currently known as the Malthusian growth model.
KEY TAKEAWAYS
Thomas Malthus was an 18th-century British philosopher and economist noted for the Malthusian growth model, an exponential formula used to project population growth.
The theory states that food production will not be able to keep up with growth in the human population, resulting in disease, famine, war, and calamity.
A noted statistician and proponent of political economy, Malthus founded the Statistical Society of London.
Describe the fish and the algae’s role in cycling carbon in the atmosphere/water (environment) from the above illustration. Write in complete sentences, and make sure to include in your answer:
What impact do fish have on the amount of CO2 in the water
What impact does algae have on the amount of CO2 in the atmosphere
Which organism, fish or algae, can store carbon and how
Explain whether each organism uses or produces CO2
Answer:
Please find the explanation below
Explanation:
Carbon cycle is the series of activities that utilize and release carbon from and into the atmosphere respectively. Carbon in the form of carbon dioxide (CO2) moves in and out of living organisms. In this case involving the fish (an animal) and an algae (a protist).
Fishes are animals, hence, they undergo RESPIRATION process to release carbon dioxide into the atmosphere as a waste product, hence, making C02 concentration in a water body increase. However, contrarily, algae are photosynthetic organisms that make use of carbon dioxide as a carbon source when undergoing the process of photosynthesis. Hence, they reduce the amount of C02 in the atmosphere.
Carbon is stored as biomass in every living organisms. For example, when the fish feeds on algae, it digests it and forms carbon compounds which get stored until they die and get decomposed, which release the stored carbon in them.
Fish produces C02 via the process of respiration respiration while algae uses the C02 via the process of photosynthesis.
Why do roadside plants die frequently after salt trucks salt the roads?
A. Plants lose water to the soil because there is more water there
B. Plants can't take up water in their roots because the solute balance is "off"
C. All of these
D. Plants don't like salt, but take it into the roots anyway
Answer:
B.
Explanation:
Nature loves balance
due to the salt, and inbalance the plant will die of dehyration, same as people drinking sea water
Plants can't take up water in their roots because the solute balance is "off" so roadside plants die frequently after salt trucks salt the roads
How does plant take up water from soil ?
Osmosis is the process by which water moves into the roots of plants. The amount of salts in the water in the plant and the water in the soil determine how much water moves into the roots.Water may flow back into the soil from the plant roots if the salt level in the soil water is too high. The plant becomes dehydrated as a result, decreasing its yield or even dying.Even though the effects of salinity may not be obvious, crop yield losses may occur. The capacity of a particular crop to extract water from salinized soils determines its salt tolerance.By interfering with nitrogen uptake, reducing growth, and stopping plant reproduction, salinity affects crop, pasture, and tree production.The plant becomes poisoned and dies as the concentration of some ions, like chloride, that are toxic to plants rises.The salinization of rivers that were previously clean is dryland salinity's most significant off-site effect. This has serious financial, social, and environmental repercussions for both urban and rural communities, affecting the quality of water used for drinking and irrigation.The taste of drinking water may be affected by high salt concentrations. Particularly chloride has a low taste threshold. The levels of sodium and magnesium sulfate in drinking water may cause constipation and make it less suitable for grazing animals.

The ecology question above says : A fast swimming strong body fish such as a swimming which is adapted to clear fast and strong water current would most likely be found in which aquatic zone?
Which answer is correct????
Correct question: A fast swimming strong body fish such as a salmon which is adapted to clear fast and strong water current would most likely be found in which aquatic zone? Options in the attached file
Answer:
Source of a river zone
Explanation:
The fishes body is directly correlated with their environment and the pressures they receive from it. Those animals that are used to living in clear waters, with fast currents must be very strong, must have a hydrodynamic torpedo-like body and big and strong caudal fin to propel against the currents. These animals are used to living in water masses such as the source of a river zone.
Rivers belong to lotic environments, characterized by constant moving water.
Profundal zone: Sunlight can not reach this zone, so there are no plants. The Water movement is very limited, and in most cases, water is not clear.Littoral zone: Is the transition zone, near the shore, where the light easily reaches the bottom. Usually, there is plenty of vegetation fixated to the bottom. Wetland zone: In general these are calm water, very rich in diversity, and a proper breeding area for a wide variety of fish. Source of a River zone: Rivers flow from higher to lower areas. They originate at the top of the mountains and fastly descend to finally end in a lake or in the sea.Some species of salmons characterize by living in the sea during sexual maturity, but whenever they need to breed, they go back to the area where they were born. This is in sweet water. They swim in the river until they reach the place where they are going to oviposit. In order to do this, they need to swim against the current. Many times, females die trying to reach this special place.
