Answer:
Due to muscle contraction and fighting of white blood cells.
Explanation:
Exercise increases the temperature of body because about 20% of the energy produced in contracting muscles is used for muscle contraction while the remaining 80% is converted into heat energy, as a result body's temperature increases whereas a person who has infection also experience high body temperature because the body work faster to fight against the infection that leads to high temperature.

Answer:
Somatic mutations are mutations that occur in body cells, that is the cells that do not make gametes. These mutations are not passed on to further generations; for example, if a mutation that changes a gene in a skin cell would not affect your children because skin cells don't produce gametes.

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.
define magnification and cisternae?
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.

An archer shot a 0.06 kg arrow at a target the arrow accelerated at 5,000 m/s squared to reach a speed of 50.0 m/s as it is left the bow.During this acceleration what was the net force to the nearest newton?
Answer:
the net force to the nearest newton is 300 N
Explanation:
The computation of the net force to the nearest newton is shown below:
According to the newton second law of motion, the force is proportional directly to the change rate in momentum
So,
Resulted force = mass × acceleration
F = 0.06 kg × 5,000 m/s
= 300 N
Hence, the net force to the nearest newton is 300 N
Answer:
300 N

which characteristic of living organisms is responsible for the production of oxygen in the leaf of a plant exposed to sunlight.
Answer:
Photosynthesis.
Explanation:
Photosynthesis is a characteristic of living organisms and it is typically responsible for the production of oxygen in the leaf of a plant exposed to sunlight. It is a chemical process used by plants to obtain food from sunlight.
All living organisms such as plants and animals require energy to function properly (life activities). Thus, the cell organelle where energy from nutrients is released is generally referred to as mitochondria. Animals and plants retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

D. Age of organisms when they died
Answer: changes in climate
Change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).
What are Fossils?A fossil is defined as the preserved remains, impression, or trace of a once-living thing from a past geological age, including bones, shells, exoskeletons, fossilized traces of animals or microbes, amber, hair, petrified wood, and DNA. The totality of fossils is known as the fossil record.
There are five types of fossils which are as follows:
Body FossilsMolecular FossilsTrace FossilsCarbon FossilsPseudo fossilsThe fossil record shows that the types of living things on Earth changed over time which reveals the Earth's history.

Drop a paper a piece of thermocol and a piece of plastic from a height of 10 to 15 feet not the time for each object to hit the ground why does paper take more time than thermocol and thermocol more than the plastic piece make the paper to fell down in such a way that it should hit the ground before all of them and how does it happen
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.
