Why are viruses not considered to be living organisms?
Answer:
Cant reproduce
Explanation: Viruses cant reproduce by themselves they need a host cell that they take control of which provided all of the essential functions a living oraganism would provide in order to make more copies of itself hope this helps god bless
Answer:
they are acelluar
Explanation:
Viruses, like bacteria, are microscopic and cause human diseases. But unlike bacteria, viruses are acellular particles (meaning they aren't made up of living cells like plants and animals are), consisting instead of a central core of either DNA or RNA surrounded by a coating of protein.
Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli. They also don't reproduce independently but must replicate by invading living cells.
Mistletoe seeds stick to bark When the seed germinates, a root-like part digs through the bark into the sap-filled living wood of.
sap Mistletoe slows the growth of trees and, in large numbers, may
kill the tree. Which of the following best explains the relationship between trees and mistletoe?
A. Mistletoe is a predator that lives on trees by consuming them for food
B. Mistletoe is a parasite that lives on trees by taking some of the trees' food and water
C.
Trees provide shelter for mistletoe, and mistletoe provides food for the trees
D.
Trees provide shelter for mistletoe, and mistletoe helps the trees reproduce
Final answer:
Mistletoe is a parasite to trees, as it attaches to them and extracts nutrients and water, which can hinder the tree's growth and potentially lead to its death without offering any advantages to the tree.
Explanation:
The relationship between trees and mistletoe can best be explained as a parasitic one. Mistletoe seeds adhere to the bark of a tree and, upon germination, send root-like structures into the sap-filled living wood to draw out the tree's nutrients and water for its own growth. This can lead to the slowing of the tree's growth and potentially its death if infestation is extensive.
Parasitic relations are defined by one organism benefiting at the expense of another, which is the case with mistletoe and trees. Unlike other plant relationships where there may be mutual benefits, mistletoe does not provide any known advantage to the trees it infests. Therefore, the correct answer to the student's question is B. Mistletoe is a parasite that lives on trees by taking some of the trees' food and water.

Energy resources, the ease of attaining them, and the methods in which they are used, directly relate to economic growth of a country
as well the overall many other aspects of life within that country. All but one is directly related to energy and sustainable
development. That is
A) Family size
B) Per capita income
C) The health of the citizens
D) Availability of clean water
Answer: A. Family size
Explanation:
I just got the shÎt wrong for you .
Family size is not directly related to energy and sustainable development, while per capita income, citizen health, and clean water access are. Economic well-being often coincides with higher energy usage, and sustainability requires balancing energy development with environmental protection.
The aspects of life within a country that are directly related to energy and sustainable development include per capita income, the health of the citizens, and availability of clean water. However, family size is not directly related to energy and sustainable development. Economic well-being is highly dependent on energy use, with most countries displaying a correlation between higher standards of living, measured by GDP per capita, and higher levels of energy consumption per capita. This relationship indicates that access to sufficient and reliable energy resources is crucial for economic growth and maintaining the quality of life.
The world faces a challenge in balancing the development of energy resources against the environmental impact caused by their extraction and use. Increasing the efficiency of energy use can change the dependency on high levels of consumption. It's also important to consider transitioning to renewable energy sources to ensure a sustainable future.

Explanation:
Algae are small photosynthetic organisms found in aquatic ecosystems. As algae grow, they produce and store a carbon-rich oil in their cells. Up to 40% of their body mass can be taken up by oil. Scientists discovered a way to extract the oil to create algae fuel, a biofuel that can be used in place of fossil fuels. Scientists expected that algae would be able to produce up to 60 times more oil per acre than plants, like corn, that are commonly used to produce biofuel.
To commercially produce algae oil, very large ponds for algae growth were constructed. However, scientists soon made two discoveries.
As the algae grew on the ponds, they crowded and shaded one another.
Many insects and other consumers frequently entered the ponds.
Why would these be a problem for algae oil production?
A.
Consumers feed on algae, so they cause the energy stored in algae oil to be permanently lost from the environment.
B.
Shading reduces access to sunlight, so algae produce fewer sugars and are less able to store energy in the oil.
C.
Insects feed on algae, so they cause all of the energy stored in algae oil to be converted back into light energy.
D.
Crowding reduces access to food, so it makes algae less able to take in the sugars needed to produce oil.
Answer:
B
Explanation:
Let's try to eliminate answer choices.
A) "Consumers feed on algae, so they cause the energy stored in algae oil to be permanently lost from the environment." The incorrect part here is that it says the energy is "permanently lost from the environment", but this is not true. All energy is constantly being recycled and by the Law of Conservation of Energy, energy cannot be destroyed or "lost".
B) "Shading reduces access to sunlight, so algae produce fewer sugars and are less able to store energy in the oil." This is correct.
C) "Insects feed on algae, so they cause all of the energy stored in algae oil to be converted back into light energy." This is incorrect because it says that all the energy is converted back into light energy. However, if insects eat the algae, it's not possible for that energy to become light energy; light energy can only come from the sun.
D) "Crowding reduces access to food, so it makes algae less able to take in the sugars needed to produce oil." This is incorrect because the algae doesn't take in sugar; it produces the sugar.
Thus, the answer is B.

Bald cypress is most likely to found in wetland. Thus, option C is correct.
What is wetland?The area of the land which is either covered by water or saturated by water is called as wetland. A major factor that distinguishes wetlands from terrestrial landforms and bodies of water is the characteristic vegetation of aquatic plants adapted to unique anoxic, water-bearing soils.
Wetlands are considered to be among the most biologically diverse of all ecosystems, and are home to a wide variety of species of plants and animals. Methods to assess wetland function, wetland ecosystem health and wetland overall condition have been developed in many parts of the world.
Bald cypress is an example of a tree adapted to growing in wetlands, but gum, willow, alder, and maple are also commonly found. Tropical wetlands have many types of trees, which also includes palm trees. Therefore option C is correct.

Hemisphere? (AKS 6c, DOK 2)
Noon
West
East
June 21st represents the sun in the sky at noon for the northern hemisphere.
Explanation:
The summer is hotter because the sun's part is higher in the sky. This reason makes the days longer and makes summer sun more intense.
The summer solstice for northern hemisphere occurs in june 21. On this day the sun's position at noon is higher in altitude of the year.
In the summer season , The north pole is tilted towards the sun and this causes the sun's part to be higher in the sky causing the northern hemisphere to receive more light and heat.
The process of photosynthesis converts carbon atoms from carbon dioxide into _______. A. sugars B. hydrogen C. oxygen D. salts
Answer:
A. sugars
Explanation:
The photosynthesis equation is:
CO2(carbon dioxide)+ H2O (water) +sunlight --> O2(oxygen) + C6H12O6 (glucose)
Photosynthesis makes sugar (glucose) and oxygen. But, oxygen is just oxygen, and there are no carbon atoms in O2.
Glucose is C6H12O6, and the C represents carbon. So, photosynthesis converts carbon atoms from CO2 to sugars.
Therefore, the choice is A.

The trophic level which includes the greatest amount of available energy is made up of
organisms which-
Z. break down organic matter to release energy.
Y. convert sunlight to chemical energy.
X. hunt animals for their energy needs.
W. receive the energy they need from plants.
Answer:
z
Explanation:
Organisms that convert sunlight to chemical energy, called photoautotrophs, make up the trophic level with the greatest amount of available energy. Energy is lost at each transfer up the food web, so primary producers (photoautotrophs) embody the most energy. Energy transfer efficiency is termed trophic level transfer efficiency.
Explanation:The trophic level with the greatest amount of available energy is made up of organisms that convert sunlight to chemical energy. These organisms are known as photoautotrophs and include plants, algae, and photosynthetic bacteria. They harness the solar energy of the sun by converting it to chemical energy in the form of ATP (and NADP). The energy stored in ATP is used to synthesize complex organic molecules, such as glucose.
Energy flows from the bottom to the top of the food web in an ecosystem, with energy being lost at each transfer. This is why the primary producers (the photoautotrophs) have the most energy available. They form the base of the food web and provide energy to all other trophic levels.
The efficiency of this energy transfer to other trophic levels is termed the trophic level transfer efficiency (TLTE). As per the second law of thermodynamics, large amounts of energy are lost as metabolic heat when organisms from one trophic level consume the next level, reducing the amount of energy available at higher trophic levels.

3. What structure is used to transport organic molecules from the leaf to other parts of the plant?
The structure used to transport organic molecules from the leaf to other parts of the plant is the phloem.
Phloem is a unique tissue found in plants that is organized into a network of interconnected tubes or sieve components. Phloem vessels are made up of these tubes and supporting cells. The main job of the phloem is to move organic compounds such as sugars, amino acids and hormones from the plant's photosynthetic site in the leaves (source) to other areas where they are needed (sink). Translocation, a method of transport that relies on pressure gradients and active transport processes, is how this movement is accomplished.

Summarize what the researchers did to improve the quality of post mining site soil
Answer:
The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.
A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic. The compacted soil after mine proves harder to bring seed into the soil.
The researchers try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created “planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.
Final answer:
Researchers improve post-mining site soil by ensuring safety, removing pollutants, restoring biodiversity, and rehabilitating waterways. They analyze soil content, address specific soil stress factors, and use soil laboratory analysis for making input recommendations. Encouraging mining companies to restore old sites involves creative and incentivizing strategies.
Explanation:
Improving Post-Mining Site Soil Quality
Researchers have approached the rehabilitation of post-mining sites with comprehensive strategies to improve soil quality and restore ecosystem functions. They ensure the site is safe and stable, remove pollutants that contaminate the site, aim to restore biodiversity similar to conditions before mining, and rehabilitate waterways to their previous state. In-situ moisture content and in-situ density of soil are analyzed to assess field conditions effectively. To address aluminum stress on acid soils, which is detrimental to agriculture, researchers seek scientific foundations for innovative strategies. Assessment of site quality often involves examining site variables like soil composition and correlating them with plant growth, though this process can be expensive and labor-intensive. Methods such as wetland creation, revegetation, and agroforestry are employed to prevent flooding, soil erosion, increase grass production, and improve overall soil health. Soil input recommendations are carefully crafted based on soil laboratory analysis, helping to manage the dynamic and complex soil systems in an efficient way.
Encouraging mining companies to proactively rehabilitate old sites might involve creative ideas like implementing incentives, showcasing successful rehabilitation case studies as models, and developing partnerships that align the companies' interests with environmental stewardship. Researchers stress the importance of understanding the dynamic and holistic nature of soil systems to effectively target interventions for yielding substantive improvements in soil quality and ecosystem recovery on post-mining sites.
