Answer:
Nearly all of the Earth's atmosphere is made up of only five gas es: nitrogen, oxygen, water vapor, argon, and carbon dioxide. Several other compounds are also present. Although this CRC table does not list water va por, air can contain as much as 5% water vapor, more commonly ranging from 1-3%.
Explanation:
Site: Go ogle sorry...
The Earth's atmosphere is primarily composed of nitrogen (78%) and oxygen (21%), with trace amounts of other gases such as argon, carbon dioxide, and neon. Water vapor levels vary but can reach around 4%. Additionally, there are trace amounts of various gases, including methane and ozone.
In the Earth's atmosphere, nitrogen and oxygen predominate. At around 78%, nitrogen predominates, with oxygen making up around 21%. These two gases are necessary for maintaining life since oxygen is required for breathing and nitrogen is used by plants and other living things.
Smaller amounts of other gases like neon, carbon dioxide, and argon are also present. Water vapor plays a significant effect on weather and climate, fluctuating but sometimes reaching 4%. Methane, ozone, and other trace gases are present in small levels yet have a big impact on climate, affecting greenhouse effects and atmospheric chemistry.

You see a volcano with relatively steep sides and sticky lava that does not flow easily. It produces explosive eruptions due to gas building up in the viscous magma. What type of volcano is this?
Claim:
Evidence:
Reasoning:
You see a volcano which produces low viscosity, runny lava, it spreads far from the source and forms a volcano with gentle slopes. It is formed by thick lava that flows slowly and is not explosive.
What type of volcano is this? Use the sentence starters from the previous slides: Claim:
Evidence:
Reasoning:
Answer:
Stratovolcano Stratovolcanoes
Explanation:
Stratovolcano. Stratovolcanoes have relatively steep sides and are more cone-shaped than shield volcanoes. They are formed from viscous, sticky lava that does not flow easily. The lava therefore builds up around the vent forming a volcano with steep sides.

With an increase in farming comes an increased impact on the environment. Why would increasing amounts of pesticides in the soil and groundwater be bad?
Answer: Pesticides are found as common contaminants in soil, air, water and on non-target organisms in our urban landscapes. Once there, they can harm plants and animals ranging from beneficial soil microorganisms and insects, non-target plants, fish, birds, and other wildlife.

Increasing amounts of pesticides in the soil and groundwater be bad because they are harmful to the health of humans and animals, and they cause very harmful diseases.
What are pesticides?Chemicals known as pesticides are used to control or kill pests that threaten crops on farmlands. These pesticides are harmful to the health of people and animals if consumed, even if they aid the farmer in eliminating his pest problem and probably boost productivity.
Pesticide tolerance, as established by the Environmental Protection Agency (EPA), refers to the quantity of a pesticide chemical that can be applied to a product.
Therefore, growing concentrations of pesticides in the soil and groundwater are problematic, since they endanger both human and animal health and lead to extremely dangerous diseases.

How does heart failure affect the lungs?
Carbon dioxide enters the lungs.
Blood leaves the lungs.
Fluid can build up in the lungs.
Too much oxygen enters the lungs.
Answer:
A damaged heart can't pump blood as effectively from your lungs out to your body. Blood backs up, raising pressure in the veins inside your lungs. This pushes fluid into your air sacs. As liquid builds up, it gets harder to breathe.

Answer:
You are correct it's the earth!
Explanation:
The reason why is because, the term "elliptical orbit" is used in astrophysics and astronomy to describe an oval-shaped path of a celestial body. The Earth, as well as all the other planets in the Solar System, follow this type of orbit around the Sun. The shape is created by the varying pull of forces, such as gravity, on two objects, such as the Sun and a planet.

A cyclist travel 9 km in 30 minutes. What is the students average speed in km/h?
A.14 km/h
B.16 km/h
C.18 km/h
D.20 km/h
The students average speed is 18km/h. So, the correct option is C.
What is Speed and Velocity?Speed is defined as the time rate at which an object is moving along a path, whereas velocity is defined as the rate and direction of motion of an object. Speed is a scalar quantity as it has only magnitude, whereas velocity is a vector quantity as it has both magnitude and direction.
Speed is expressed as
Speed= Distance/ time taken
Velocity is expressed as:
Velocity= Displacement/ Time taken
Both are expressed as meter per second. (m/s)
For above given information,
If student travelled 9km in 30 minutes
So, it will cover in 1hr = 9* 60/30 = 18km/hr
Thus, the students average speed is 18km/h. So, the correct option is C.

The more homologous structures two species have, the ________ closely related they may be.
Answer:
more closely
Explanation:
The more alike the structures are the more closely related the organisms are to one another.
The more homologous structures two species have, the more closely related they may be, as homologous structures are traits or anatomical features that are similar in different species.
Homologous structures are features that are similar in different organisms because they are inherited from a common ancestor. These features may have different functions in each organism, but they share a similar underlying structure. For example, the bones in the wings of a bird, the arms of a human, and the flippers of a dolphin are all homologous structures, despite having different functions and appearances. The degree of similarity of homologous structures can be used as an indicator of how closely related two species are to each other.
