Explanation:

Energy reaches the Earth in the form of electromagnetic radiation.

Terrestrial solar radiation means solar radiation that reaches the Earth after passing through the Earth's atmosphere. About 97% of solar radiation reaches the Earth in the range of wavelengths 0.29 - 2.5 μm, and about 3% with wavelengths greater than 2.5 μm.

Answer:

Genetic relationships are analysed based on the comparison of allelic identity or differences, regardless of the number of SNPs that differ between two alleles of a gene, which simplifies the analysis.

Explanation:

Answer:

Materials

• Scrap piece of paper

• Pen or pencil

• Clock or timer that shows seconds or a helper with a watch

• Comfortable exercise clothes (optional)

• Calculator

Preparation

• Practice finding your pulse. Use the first two fingers of one hand to feel your radial pulse on the opposite wrist. You should find your radial pulse on the "thumb side" of your wrist, just below the base of your hand. Practice finding your pulse until you can do it quickly. (You can alternatively take your carotid pulse to do this activity, but be sure you know how to safely take it and press on your neck only very lightly with your fingers.)

• Measure your resting heart rate, which is your heart rate when you are awake but relaxed, such as when you have been lying still for several minutes. To do this, take your pulse when you have been resting and multiply the number of beats you count in 10 seconds by six. This will give you your resting heart rate in beats per minute (bpm). What is your resting heart rate? Write it on a scrap piece of paper.

• You will be measuring your heart rate during different types of physical exercises over a period of 15 minutes. Choose at least two different exercises. Some examples include jumping rope, lifting a two-pound weight, riding a bike, hula-hooping, walking, etc. Gather any needed materials. (If you want to make a homemade hula-hoop, steps for doing this are given in the activity Swiveling Science: Applying Physics to Hula-Hooping .) Do you think the activities will affect your heart rate differently? How do you think doing each activity will affect your heart rate?

Procedure

• Choose which exercise you want to do first. Before starting it, make sure you have been resting for a few minutes so that your heart is at its resting heart rate.  

• Perform the first exercise for 15 minutes. While you do this, write down the number of beats you count in 10 seconds after one, two, five, 10 and 15 minutes of activity. (You want to quickly check your pulse because it can start to slow within 15 seconds of stopping exercising.) How do the number of beats you count change over time? How did you feel by the end of the exercise?

• Calculate your heart rate after one, two, five, 10 and 15 minutes of exercise by multiplying the number of beats you counted (in 10 seconds) by six. How did your heart rate (in bpm) change over time?

• Repeat this process for at least one other exercise. Leave enough time between the exercises so that your heart rate returns to around its normal resting level (this should only take a few minutes). How did you feel by the end of the second exercise? How did your heart rate change over time for this exercise?  

• Take a look at the results you wrote down for this activity. Which exercise increased your heart rate the most? Which exercise increased your heart rate the fastest? Which exercise(s) elevated your heart rate to the target heart rate zone (50 to 85 percent of your maximum heart rate, where your maximum heart rate is 220 bpm minus your age)? Do you notice any consistent patterns in your results?

• Extra: Try this activity again but test different physical exercises. How does your heart rate change when you do other exercises? How are the changes similar and how are they different?

• Extra: Measure your heart rate while lying down, while sitting down, and while standing. How does your heart rate change with body position?  

• Extra: Repeat this activity with other healthy volunteers. How does their heart rate compare to yours? How does their change in heart rate while exercising compare to how yours changed?  

• Extra: Try this activity again but vary the intensity of your exercise. What intensity level elevates your heart rate to 50 percent of its maximum heart rate? What about nearly 85 percent of its maximum? Be sure not to exceed your recommended target heart rate zone while exercising

Explanation:

If you did a moderately intense exercise, such as walking, you may have seen an initial jump in your heart rate (where your heart rate falls within the lower end of your target heart rate zone within about one minute of exercise), but then your heart rate only slowly increased after that. After 15 minutes, you may have reached the middle of your target heart rate zone. To reach the upper end, people usually need to do a moderately intense exercise for a longer amount of time (such as for 30 minutes). If you did a more strenuous exercise—hula-hooping, for example—you may have seen a higher initial bump in your heart rate (such as reaching the middle of your target heart rate zone after just one minute of exercise), and then your heart rate stayed about the same for the remaining 14 minutes of exercise. Overall doing a more strenuous exercise generally raises a person's heart rate faster compared to doing an exercise that is only moderately i

Answer:

Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.

Explanation:

It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.

Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".

A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.

Answer:

The paper takes more time to fall than the piece of thermocol because it experiences a greater air resistance than the thermocol.

The thermocol takes more time than the piece of plastic because it experiences a greater air resistance.

The piece of paper can be made to fall faster than all of them and hit the ground faster by crumpling it and then giving it an initial velocity by throwing it downwards.

Explanation:

Objects falling freely due to the force of gravity alone are accelerated downwards at a constant value 9.8 m/s². This acceleration due to gravity is constant for all objects on the earth's surface and is independent of the mass of the objects.Therefore, when objects are release from the same height and allowed to fall freely under gravity, they are accelerated downwards to the same extent and are expected to hit the ground at the same time. However,due to the resistance of the air through which the objects are falling, they may hit the ground at different times depending on the shape of the falling objects.

Objects which have a greater surface area or volume per unit mass will experience a greater air drag or resistance and therefore, will take a longer time than objects of similar mass with a smaller volume or surface area.

The paper has a greater surface area per unit mass than the piece of thermocol, therefore, it takes more time to fall than the piece of thermocol because it experiences a greater air resistance than the thermocol.

The thermocol has a greater surface area per unit mass than the piece of plastic, therefore, it takes more time than the piece of plastic because it experiences a greater air resistance.

The piece of paper can be made to fall faster than all of them and hit the ground faster by crumpling it, thereby reducing its surface area per unit mass it and then giving it an initial velocity by throwing it downwards.

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.

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.

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.
