Pls help due soon: Why is the moisture of cirrus clouds mostly in the solid state?
The moisture of cirrus clouds mostly in the solid state as the higher altitude allows for lower temperatures, leading to frozen water crystals. The correct option is A.
What are cirrus clouds?These clouds indicate that the weather is favorable. They are distinguished by their high altitudes, which reflect the direction of the wind, which moves them and constantly changes their shapes.
The higher they are, the lower the temperatures; son water vapor condenses into crystals, which are blown in different directions by the wind.
Cloud formation occurs when humid air ascends and experiences adiabatic cooling due to the high temperature.
Because the density and pressure of the air decrease as altitude increases, the air tends to expand with elevation in response to the reduced pressure.
Gases in expansion experience adiabatic cooling, losing caloric energy as their molecules move further apart. As the air rises, it becomes colder and thus denser.
Thus, the correct option is A.

Which of the following is NOT one of the major land biomes? a. tropical rain forest c. temperate grasslands b. temperate savanna d. temperate deciduous forest
Answer:
Temperate Savanna.
Explanation:
Savanna is not temperate, it is also called tropical grasslands, further supporting my answer. It is PART of the kinds of grasslands, So because it is a part, it is not a major Biome.
Temperate savanna is not the major land biomes.
What is Biomes?Some of the electrons in metallic atoms are held there quite loosely. As a result, they frequently lose electrons and generate cations. In contrast, most nonmetallic atoms have a stronger attraction to electrons than do metallic atoms, and as a result, they gain electrons to form anions.
As a result, when two atoms from a metallic and a nonmetallic element unite, the nonmetallic atoms usually tend to take one or more electrons from the metallic atoms and create ions.
One-third of the Earth is covered in forests, which are primarily made up of trees. A large portion of the terrestrial biodiversity of the planet, including insects, birds, and mammals, is found in forests.
Therefore, Temperate savanna is not the major land biomes.

Evaluate if knowing the type of the source of pollution helps make clean-up easier. Justify your opinion in 4-6 sentences and using at least 3 direct quotes from the article.
Knowing the source of pollution aids in clean-up because the nature of pollutants and how they are recycled differ, so knowing the type and amount of pollutants aids in pollution cleanup.
What is the significance of knowing the types of pollution?Knowing the source of pollution can make clean-up easier because it allows for targeted and effective removal of the pollutants as it identifies the specific source of the pollution rather than trying to address pollution throughout a wider area. It also helps in determining the most appropriate remediation technique to use, the cost of clean-up, etc.
Hence, knowing the source of pollution aids in clean-up because the nature of pollutants and how they are recycled differ, so knowing the type and amount of pollutants aids in pollution cleanup.

Both species benefit in the type of symbiosis called parasitism. Please select the best answer from the choices provided T F
The statement “both species benefit in the type of symbiosis called parasitism” is false.
Parasitism is a type of symbiosis where one organism is harmed while the other benefits.
An example of parasitism is a dog infested with ticks.
The ticks benefit from drinking the dog’s blood, harming the dog in the process.

Describe two things that would happen in an ecosystem if there were no unicellular organisms. Explain why something with only one cell can be considered to be an organism.
Unicellular organisms include bacteria, protists, and yeast. For example, a paramecium is a slipper-shaped, unicellular organism found in pond water. It takes in food from the water and digests it in organelles known as food vacuoles. Nutrients from the food travel through the cytoplasm to the surrounding organelles, helping to keep the cell, and thus the organism, functioning. Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells. One can easily observe the differences in these cells under a microscope. Their structure is related to their function, meaning each type of cell takes on a particular form in order to best serve its purpose. Nerve cells have appendages called dendrites and axons that connect with other nerve cells to move muscles, send signals to glands, or register sensory stimuli. Outer skin cells form flattened stacks that protect the body from the environment. Muscle cells are slender fibers that bundle together for muscle contraction. The cells of multicellular organisms may also look different according to the organelles needed inside of the cell. For example, muscle cells have more mitochondria than most other cells so that they can readily produce energy for movement; cells of the pancreas need to produce many proteins and have more ribosomes and rough endoplasmic reticula to meet this demand. Although all cells have organelles in common, the number and types of organelles present reveal how the cell functions.

If there were no unicellular organisms available in the ecosystem then there will be no atmospheric nitrogen fixation and no recycling of organic matter into plant usable products.
Unicellular organisms are small single celled organisms that can be observed through microscope but not with naked eye. The unicellular organisms are bacteria, fungi, virus, and protists. If no unicellular organisms are present in the ecosystem then there will be no nitrogen fixation by the soil bacteria like Nostoc, Cyanobacteria, and others. Since, plants cannot utilize atmospheric nitrogen directly so these bacteria convert the atmospheric nitrogen into plant usable form that is ammonia. When no soil bacteria present in the soil ecosystem then the plants will not be able to grow as ammonia is a chief ingredient of many biomolecules in plants. If there will be no unicellular organisms then there will not be any decomposition process of the organic matter and the waste of dead animals, plants, and other living beings will not recycle into plant usable form this will limit plant growth and will also affect the natural cleaning mechanism of ecosystem. Only one cell can be considered an organism if it shows characteristics of an organism like food intake, respiration, reproduction, and growth.Hence, if there were no unicellular organisms available in the ecosystem then there will be no atmospheric nitrogen fixation and no recycling of organic matter into plant usable products.
