Answer:
Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and out-going infrared (thermal) radiation that are part of Earth’s energy balance. Changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system. Since the start of the industrial era (about 1750), the overall effect of human activities on climate has been a warming influence. The human impact on climate during this era greatly exceeds that due to known changes in natural processes, such as solar changes and volcanic eruptions.

Answer:
1. Increases
2. Decreases
3. Increases
4. Decreases
5. Increases
6. Increases
Explanation:
Raising air temperature increases temperature of our body while on the other hand, if the air temperature decreases the temperature of our body also decreases because high air temperature heats up our skin surface and low air temperature cools down our skin surface which ultimately increases or decreases the internal body temperature. Adding clothing increases body temperature due to capturing of heat produced by our body. Sweating cools down our body temperature because the water takes the internal heat with itself to the outside. In shivering, the body produced heat so the body temperature increases. Exercising also produces heat inside our body which increases the body temperature.

explain how the structure of a book lung allows it to perform its function
Answer:
Book lungs are within small openings in the abdomen of the arachnid. The book lungs themselves consist of a series of haemolymph filled plate-like structures. Between the plates there is an air space and this allows air to circulate around the plates. Gaseous exchange then occurs through the surface of the plates.

I NEED HELP PLEASE!! There are two forms of PKD- autosomal Dominant and
autosomal recessive. Since
Aditya has the dominant form,
if he marries a woman with no family history of PKD, what
are the chances their children will inherit the gene? Show
a punnett square to illustrate your answer
Answer:
Highly likely
Explanation:
ADPKD-AUTOSOMAL DOMINANT POLYCYSTIC KIDNEY DISEASE:-here aditya is affected with ADPKD,and if he marries a women with nofamily history of such disease ,in autosomal dominant PKD,people of this condition are born with one mutated copy of PKD1 OR PKD2 GENES and there are 90% chances that from one affected person with this disease will pass down to the progeny(next generation) and both male and females are equally affected. As for the punnett square, I don't remember those at all, I'm sorry :(
If Aditya has the autosomal dominant form of PKD, he must have inherited at least one copy of the PKD gene from one of his parents. Therefore, Aditya's genotype is either heterozygous (PKD/Pkd) or homozygous dominant (PKD/PKD).
What is PKD?PKD stands for polycystic kidney disease, which is a genetic disorder that causes multiple cysts to develop in the kidneys. There are two types of PKD: autosomal dominant PKD (ADPKD) and autosomal recessive PKD (ARPKD).
If Aditya marries a woman with no family history of PKD, she is most likely homozygous recessive (pkd/pkd).
Using a Punnett square, we can determine the probability of their children inheriting the PKD gene:
PKD Pkd
pkd Ppkd Ppkd
pkd Ppkd Ppkd
Each box represents a possible offspring genotype, with the probability of each genotype indicated in the box. From this Punnett square, we can see that:
50% of their children will inherit one copy of the PKD gene (heterozygous, Pkd/pkd)
50% of their children will inherit two copies of the normal gene (homozygous recessive, pkd/pkd)
Therefore, there is a 50% chance that their children will inherit the PKD gene.

Read the excerpt from How Hurricanes Form.
Hurricanes are often compared to engines. Just like engines, they need a type of fuel. Hurricanes form over warm ocean waters near the equator. For hurricanes, their fuel is warm, moist air. When hurricanes form, the warm, moist air above the ocean rises upward from close to the surface of the water. Because the warm air rises, it results in less air under the surface of the water. This area with less air is known as an area with low pressure.
Air from areas surrounding this low pressure space pushes in to the area. This fills the low pressure area. The new air in this space becomes warm and moist and also rises. As the air continues to rise, the air surrounding the space swirls in to take its place. This process of air swirling in to replace air that has risen continues. Eventually, the moisture in the air forms clouds.
The wind and the clouds that form create a system. A system is a pattern of weather. The system of clouds and winds continues to spin and grow. The water evaporating from the ocean's warm surface acts as the fuel, which is what helps this spinning and growing. The system rotates faster and faster until the eye of the storm forms in the center area. Ironically, the eye of the storm is the calmest part, and it has very low air pressure. The higher pressure above the hurricane continually flows down into the eye.

why is there minimal seismic and volcanic activity in New York
NY1 does state that New York is not close to a tectonic plate, and it is uncertain which one of these faults—if any—would be the source of a strong earthquake.
Answer:
Explanation:
lthough the eastern United States is not as seismically active as regions near plate boundaries, large and damaging earthquakes do occur there. Furthermore, when these rare eastern U.S. earthquakes occur, the areas affected by them are much larger than for western U.S. earthquakes of the same magnitude.[1] Thus, earthquakes represent at least a moderate hazard to East Coast cities, including New York City and adjacent areas of very high population density.
Seismicity is scattered throughout most of the New York metropolitan area, with some hint of a concentration of earthquakes in the area surrounding Manhattan Island. The largest known earthquake in this region occurred in 1884 and had a magnitude of approximately 5. For this earthquake, observations of fallen bricks and cracked plaster were reported from eastern Pennsylvania to central Connecticut, and the maximum intensity reported was at two sites in western Long Island (Jamaica, New York and Amityville, New York). Two other earthquakes of approximately magnitude 5 occurred in this region in 1737 and 1783.[2][3][4]
The map shows earthquakes of magnitude 3 and greater that occurred in this region from 1924 to 2010, along with locations of the larger earthquakes that occurred in 1737, 1783 and 1884. More recently, the 2011 Virginia earthquake, a 5.8 magnitude quake centered in northern Virginia that occurred on August 23, 2011, was felt by the occupants of some buildings in Manhattan, more than 200 miles north of the quake's epicenter and caused minor physical building damage in Brooklyn.[5] There were some disruptions, including building evacuations and delays at airports, while Amtrak train service at Penn Station was also delayed.[6]
