Answer:
See the answer below
Explanation:
The greenhouse effect refers to the heating effects produced by the earth's atmosphere on the planet as a result of the atmosphere absorbing reflected radiation from the sun by the earth.
The earth's atmosphere is a blanket of gases, some of which are referred to as greenhouse gases. These gases have the capacity to trap radiations coming from the sun that is reflected by the ground layer of the earth. Thus, they produce a warming effect on the earth.
A bulk of the radiation coming from the sun is reflected back into space by the earth's stratosphere. The small percentage that passes through are dispersed in different directions and some of them pass through the atmospheric blanket to reach the ground layer of the earth. While some are absorbed by the ground itself, some are emitted back into the atmosphere where the greenhouse gases trap a large portion and prevent them from escaping back into space.
This leads to the warming of the earth and the entire phenomenon is referred to as the greenhouse effect.

how does climate and vegetation vary with latitude and elevation?
Answer:
Climate and vegetation vary with latitude and altitude of an area. Latitude measures distance from the equator; altitude measures elevation above sea level. ... Deserts have little precipitation and little vegetation. They are found in tropical, temperate, and Polar Regions.
The climate and vegetation may significantly vary with the latitude and elevation. This is because as elevation increases the temperature decreases gradually that do not favor the actual growth of vegetation.
What is Climate?Climate may be defined as a type of weather conditions that are persuading in any geographical location for a long period of time. In a more simple sense, it is characterized as the long-term pattern of weather in a particular area.
Latitude estimates the distance from the equator part of the earth and goes through the tropical, temperate, and colder regions of the earth. The vegetation is typically reduced with increasing the altitude or elevation with respect to the sea level.
It may also be noticed that the vegetation may alter with respect to the geographical location of the whole earth. It was never found to be completely absent.
Therefore, the climate and vegetation may significantly vary with the latitude and elevation.

Akshay decides one day to run a marathon without any training. After 10 minutes your lapsed and akashay, has run half a mile, he begins to get cramps in his thigh he's also breathing very rapidly what is causing the cramps on his legs?
Answer:
Lactic acid accumulation in the leg muscles
Explanation:
Muscle cramps are painful feelings caused by sudden contractions of the muscle. Cramps are caused by several reasons, however, based on the description of Akashay's activity, it is caused by ACCUMULATION OF LACTIC ACID in the leg muscles due to strenuous exercise.
According to this question, Akashay decided to run a marathon without any prior training. However, he started to get cramps on his thigh coupled with rapid breathing. There is a lack of oxygen in his cells, hence, anaerobic respiration was used leading to the formation of lactic acid. The buildup of lactic acid is what causes the painful sensation called CRAMP.

10 POINTS QUESTION: Objects of different masses are suspended from a height. Which combination of features will have the greatest gravitational potential energy?
A. high mass and high height
B. high mass and low height
C. low mass and low height
D. low mass and high height
Answer: high mass and high height
Explanation:
The gravitational potential energy is refered as the potential energy that has to do with the energy in a particular object due to the height of that object.
With the above explanation, when objects that have different masses are suspended from a height, the one that will have the greatest gravitational potential energy will be the one with a high mass and high height.
Therefore, the correct option is A.

Explanation:
Sickle cell anemia has a mutant gene in which that produces has valine amino acid instead of glutamate in the hemoglobin protein. In the given question the structure of the protein has only one difference that is the replacement of the glutamic acid in normal hemoglobin to valine in the β-globin amino acid chain in the mutant protein.
Valine 6 (beta chain) binds to a different hydrophobic patch (on the alpha chain and causes the disease in sickle cell anemia cases.

List down 5 evidence of exogenic processes and show how it affects or how it is affected by human activities.
Answer:
Mass wasting has drastic effects on human and animals life in the form of landsliding , earthquakes . Deposition is the pres in which sediments , rocks and soil are added land mass . A positive effect of deposition is that it creates new land . And negative effect is it takes away new lands .
The five (5) evidence of exogenic processes on Earth's surface include the following:
1. Weathering.
2. Stripping.
3. Erosion.
4. Mass wasting.
5. Deposition.
Exogenic processes can be defined as the processes that occur at or near the surface of planet Earth due to the action (influence) of exogenic forces or geomorphic agents.
The five (5) evidence of exogenic processes on Earth's surface include the following:
1. Weathering: the removal of various minerals from rocks causes depletion in oil and gas reserves that may be available for human consumption.
2. Stripping: it involves the removal of essential chemical elements and components from precious stones and landform such as a mountain.
3. Erosion: this causes flooding and washing away of various soil nutrients and as such affects agriculture.
4. Mass wasting: it moves rock debris, soil nutrients, and regolith downward, which are substances that are useful for certain human activities such as during mining.
5. Deposition: it is a consequence of erosion and it result in the laying down of sediment on a landform or landmass.
This sometimes make the foundation of buildings stronger to withstand stress.

Explain enzyme-substrate specificity.
[tex]\purple{\tt{\huge{Answer}}}[/tex]
substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.
Answer:substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.
Explanation:Enzymes and substrates share specificity in that an enzyme will only react with a specific substrate • This is because the active site is complementary in both shape and charge to a given substrate • The model by which this is known is ‘lock and key’ as the substrate is a precise structural fit for the enzyme, much like a lock and key • When the enzyme and substrate bind, they form an enzyme-substrate complex, before the substrate is catalytically converted into a product
In which direction is the wind likely to blow in the picture?

B. From the sun to the land
O O O O
C. From the land to the ocean
D. From the land to the sun
Answer:
From the ocean to the land. just took the quiz.
Explanation: a p e x
During the day, the air above land in coastal regions warms up more quickly and starts to rise, hence option A is correct.
What is the direction of the wind?As the warm air rises, a low-pressure region develops on the surface, enabling air from the sea to enter. As a result, the wind blows from the sea to the land during the day.
Predominant winds often blow east-west rather than north-south, especially in the afternoon when the land is being heated by the sun to its maximum.
the Coriolis effect causes wind systems to twist counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere most frequently in the spring and summer.
Therefore, because of the greater temperature differences between the ocean and nearby land, hence option A is correct.

what’s the chemical reaction for the digestion of fats.
Answer: The chemical reaction for the digestion of fats is when A triester is produced through the chemical reaction of three fatty acid molecules with glycerol, a molecule that contains three hydroxyl groups. When fats are broken down these fatty acid chains and glycerol are free for the body to use.
Explanation:
Lipids (fats and oils)
Lipase enzymes break down fat into fatty acids and glycerol. Digestion of fat in the small intestine is helped by bile, made in the liver. Bile breaks the fat into small droplets that are easier for the lipase enzymes to work on. Bile is not an enzyme.
