1.what effect does air pressure have on wind movement?
2.what happens to the density of air as it is heated
3. It’s a hot, sunny morning in a coastal town in south Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?
Answer: 1) Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience. 2) So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons.
Explanation: 3) Now that there are large puffy clouds in the area, most of sunlight will be clocked from reaching the earth's surface. The land will cool faster than the ocean (because water has a high heat capacity and has to lose more energy to drop by a degree which will take longer than land).
Explanation:
1)Air pressure drives the creation of wind worldwide. Although it is not the only factor, differences in air pressure throughout the Earth's atmosphere lead directly to wind and influence the speed and direction of that wind. Pressure differences also affect larger weather systems like storms, even hurricanes.
2)
Heating of the earth, which in turn heats the atmosphere, is responsible for the motions and movements of the air in the atmosphere. The faster molecules move, the hotter the air. As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons. The air is heated by the burner and the expanding air becomes less dense, causing the balloon to rise through the denser, cooler surrounding air.
How do moving glaciers change the surface of the earth??? please help!!!
Answer:
Glaciers are massive bodies of ice that move across the surface of the Earth like rivers. As glaciers move they change the surface of the Earth by wearing away loose rocks and soil and depositing them somewhere else.
Explanation:
Answer:
Glaciers change the surface of the earth by causing small or large amounts of material to be pushed out of the way as the glacier slides along a path set by gravity and angle of the slope it is on.

Why does the starch remain present and is detected by iodine in the boiled solution?
Answer:
Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. ... A blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow. I hope this helps!

Why do people have different traits
Answer:
Despite sharing some characteristics with our peers and our family members, every one of us has a unique combination of traits. Some traits are controlled by genes passed from parent to child, others are acquired through learning but most are influenced by a combination of genes and environmental factors

Which of the following is not part of cell theory?
А Cells are the basic unit of life in all organisms.
B All living things come from one or more cells.
C All cells must be able to make their own food.
D All cells come from existing cells.
Answer:
c. cells must be able to make their own food
Answer:
C. All cells must be able to make their own food.
Explanation:
The other three are the cell theory. :)
But, C is NOT, so it's the answer. Most cells don't make their own food, so it isn't something that is considered part of the theory.

Answer:
its answer is 1. cerebellum
Explanation:
The cerebellum is a part of the brain that plays a vital role in virtually all physical movement. This part of the brain helps a person drive, throw a ball, or walk across the room. The cerebellum also assists people with eye movement and vision. Problems with the cerebellum are rare and mostly involve movement .
What part of meiosis is responsible for variation?
Answer:
the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
Answer:
The two events that set meiosis apart from mitosis are known as crossing over (or genetic recombination) and independent assortment. These occur in prophase and metaphase of meiosis
During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
Explanation:
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I
Red blood cells produce the protein hemoglobin, which delivers oxygen to the body. Skin cells do not produce hemoglobin. How does this specialization take place?
A. Red blood cells have different genes than skin cells
B. Red blood cell produce DNA, but skin cells do not.
C. Different genes are activated in blood cells compared to skin cells
D. Blood cells have recombinant DNA
Answer:
A. Red blood cells have different genes than skin cells
Explanation:
This specialization takes place because, the red blood cells have different genes than the skin cells.
Red blood cells have different genes than skin cells. Therefore, option A is correct.
What is hemoglobin?Iron is a component of hemoglobin, which enables it to absorb oxygen from the air we breathe and transport it throughout the body. Hemoglobin can be thought of as the iron-containing, oxygen-transporting protein found in red blood cells. The color of red blood cells is also due to hemoglobin.
You have a low red blood cell count if a hemoglobin test finds that your hemoglobin level is lower than normal (anemia). Numerous factors, such as vitamin shortages, bleeding, and chronic illnesses, can contribute to anemia.
Skin cells do not produce hemoglobin because they have different genes than red blood cells. Therefore, option A is correct.

Where do convection currents take place? Is it in the lithosphere or the asthenosphere?
Convection currents are present in the air – A good example of convection current is the warm air that rises towards the ceiling in your house. The process happens as the warm air is said to be less dense than that of the colder air. Another good example of convection current is wind. The lithosphere is the solid, outer part of the Earth.

Often During summer months large bodies of water will experience "fish kill." These do not happen during the winter months. Explain these events using your understand of the properties of water.
Answer: see below.
Explanation:
gases dissolve more in colder water, so in summer the water can become oxygen depleted. Evaporation in summer can reduce water volume; even in summer rainfall climate evaporation rates may exceed precipitation. Evaporation will also cause higher conentrations of solutes of which some may reach toxic levels. Summer sun may also cause algal or cyanobacterial blooms which can further deplete dissolved oxygen and may release toxins into the water.
