What are the characteristics of local wind
Answer:
Mesoscale winds are better known as local winds or regional winds. A local wind can persist anywhere from several minutes to several days. Local winds can be driven by temperature and pressure differences or by variations in topography, the shape and height of Earth's surface features.
Explain how parts of a whole system contribute to the function of a whole system?
Organ systems are made up of parts that contribute to the functions of the whole system.
How do parts contribute to the functioning of the whole system?The human body system is made up of parts that work together to carry out certain functions. For example, the integumentary system conducts the function of protecting the body and consists of skin, hair and nails that integrate together to make the whole system.
The immune system an other example of the same that is made up of intricate organs, tissues and cells like the White blood cells that come together to carry out the function of keeping infections at bay.
Two or more body systems also work together to perform a particular function. Like the respiratory and circulatory systems join to provide oxygen to the cells and give out carbon dioxide.
This is how parts of the whole system contribute to the function of the whole system.

A. Individual ants together make up an ants’ nest
B. When an organism finds a new way to get itself water
C. When an organism is more successful at hunting than another
D. When people get together to stop the killing of the hawks, skunks, and weasels
Can somebody explain me, between option A and D... why option D is the right answer?(*)
(*) because someone else asked this question and people chose D here in Brainly, but there was not an explanation.
Thank you!
Answer:
D. When people get together to stop the killing of the hawks, skunks, and weasels.
Explanation:
A and D make answering this problem a bit confusing, but it's the wording that matters.
Answer A, states that Individual ants together make up an ants' nest. In other words, 1 + 1 + 1 + 1 + 1 + 1 + 1 = 7
Great, we understand that a bunch of ants means there's an ants nest in that area, but on the other hand...
Answer D, states that people get together to stop the killing of hawks, skunks, and weasels. Which means, people get together WITH A PURPOSE to stop the killing... And in order to have a purpose to stop the killing, the people must cooperate to make a change.
Otherwise, a crowd of people is just a crowd. No purpose, and no reason for cooperation like the answer choice in A with ants.
You got this! Good Luck! <3

Explanation:
Cool air can hold less water vapor than warm air. Apply this fact to explain why clouds and precipitation form on the windward side of the mountain.
Answer:
Clouds and precipitation form on the windward side of the mountain due to change in temperature and pressure.
What is the relation between pressure and temperature?
Temperature of any substance is directly proportional to the pressure of that substance.
If the temperature of the wind increases so that winds get warmer and at the same time pressure of gas also increases, due to which particles will go far from each other. After this warm air rises up and cools down will condenses to form clouds, after this precipitate will falls on the windward side of the mountain.
Hence due to temperature and pressure precipitate will form on the windward side of the mountain.

B)There would be less nitrogen available to the ecosystem.
C)There would be fewer fossils formed.
D)There would be increased rain and flooding in the soil.
Answer:
B) There would be less nitrogen in the system
Explanation:
How does bacteria affect the ecosystem?
Bacteria play important roles in the global ecosystem.
The cycling of nutrients such as carbon, nitrogen, and sulfur is completed by their ceaseless labor. Organic carbon, in the form of dead and rotting organisms, would quickly deplete the carbon dioxide in the atmosphere if not for the activity of decomposers.

Ammonia is very toxic to cells, even in moderate concentrations. Which two general strategies do organisms use to keep ammonia concentrations at safe, low levels? Select two answer choices.
To keep ammonia concentrations at safe and low levels it is transported to the liver where it is transformed into urea and glutamine. Urea is carried to the kidneys and excreted in the urine.
What is the path of ammonia in the human body?Ammonia is a substance produced by intestinal bacteria and body cells during protein digestion. It is a waste product that is normally transported to the liver, where it is transformed into urea and glutamine. Urea is carried to the kidneys and excreted in the urine.
With this information, we can conclude that to keep ammonia concentrations at safe and low levels it is transported to the liver where it is transformed into urea and glutamine. Urea is carried to the kidneys and excreted in the urine.

Explanation:
charles darwin predicted the existence of a moth with a very long "tongue" after he discovered a species of night-blooming flowers with extremely long, tube-shaped blooms. About 50 years after Darwin died, such a moth was discovered. Apply lesson concepts to explain the basis for Darwin's prediction.
The prediction of Darwin depends on the sizes of both the moth's tongue and the tube of blooming flowers.
What do you mean by Species?Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.
The moth's long tongue helps them to take the nectar from the tube of blooming flowers which are also very long. In this situation, the moths that possess long tongues survive in both conditions whether the tube of blooming flowerers is short or long.
This same concept was also predicted by Charles Darwin. The long tongue of the moth gives them the advantage in every situation of the tube's length.
Therefore, the prediction of Darwin depends on the sizes of both the moth's tongue and the tube of blooming flowers.

Amy demonstrated the formation of a type of rock. She kept a bowl of hot water in the freezer. The water solidified to form ice.
The formation of which type of rock did Amy demonstrate?
O Eroded rock
Igneous rock
Metamorphic rock
O Sedimentary rock
Answer:
Igneous rock
Explanation:
Igneous rock is formed as liquid rock in the form of magma or lava cools. In this case, the water represents lava or magma. Freezing the water changes its phase from a liquid to a solid, similar to the changing of liquid rock (magma or lava) into solid rock.
Which do you think would adapt and survive overtime to a mass extinction? A starfish or an eel?
Answer:
Starfish
Explanation:
This is an opinion questions, so there really isn't a right or wrong answer. You could just as easily choose Eel. Your task is to pick one and defend your reasoning.
I chose starfish because starfish have a long history of demonstrated adaptability to a wide variety of conditions. Their armored skin protects them from a variety of predators, as does the poison that many of them contain. They have the ability to regrow limbs, and even regrow entire starfish from certain body parts. When it comes time to breed, starfish meet together in groups. Each female releases a few million eggs from the gonads in each of her arms. Each male then releases billions of sperm from each gonad in each of his arms, thus covering the eggs with sperm to fertilize them.
4. Which scenario is an example of allopatric speciation?
A disease ravages a large fox population, killing all members that did not have a genetic resistance to the disease
A river separates members of a squirrel population that used to occupy the same geographical area
Houseflies from a certain region migrate and interbreed with a different housefly population in a neighboring area
Hawks with thin, sharp beaks primarily eat fish and small rodents, while hawks with larger beaks tend to eat reptiles and larger birds.
A river separates members of a squirrel population that used to occupy the same geographical area, Thus, option "2" is correct.
What is Allopatric speciation?Allopatric speciation is said to occur when two groups of organisms are separated by a physical or geographical barrier. Examples of such barriers are ocean, mountain range, rivers, etc. A good example of allopatric speciation is Galapagos finch.
Different species of this bird can be found in different islands at Galapos, which is located at Pacific Ocean off South America. The ocean is barrier that isolate the species from one another.
