Answer:
Our organ systems in the human body perform functions such as digesting food, breathing and transporting important nutrients for the human body to function properly. Thus, while the digestive system processes food, the respiratory system provides oxygen and the excretor eliminates waste, the circulatory system connects the different systems for the human body to function.
Explanation:
When we eat, we incorporate different nutrients that provide us with the substances and energy that our body needs to function properly. The digestive system allows us to obtain these nutrients, while the circulatory system is responsible for carrying them throughout the body. The nutrition function, which allows the use of nutrients, is carried out by the digestive, circulatory, respiratory and excretory systems. Food, once ingested, is subjected in the digestive system to crushing and chemical transformation (digestion) that results in obtaining simpler substances, converting them into soluble and assimilable substances (nutrients) that are incorporated into the circulatory system and are transported to each of the cells of the tissues. A proportion of the oxygen that is part of the inspired air and that has penetrated the lungs, enters the blood circulation in the pulmonary alveoli. In this way, oxygen enters the circulatory system to be transported to all cells in the body.

Given the following data;
Time = 0.75 hour
Speed = 88 km/h
To find the distance traveled by the car;
Distance = speed * time
Substituting into the equation, we have;
Distance = 88 * 0.75
Distance = 66 kilometers.
Therefore, the car will travel a distance of 88 kilometers.
Energy Released from the cellular respiration of glucose is
A.First stores within ATP
B.Stored in the liver as fat
C.Turned into fat
D.used directly for body activity
Answer:
During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule. To this extent, the Answer is (A)
Explanation:
Brainliest Please
Energy that is released from the cellular respiration is called as the ATP that is adenosine triphosphate. It is the energy currency of the cell.
What is the number of phosphate in ATP ?The number of phosphates in the molecule of ATP is 3 phosphates.
Glucose and the other food's molecules get broken down by the controlled stepwise oxidation in order to just provide the chemical energy in form of ATP and the NADH. Energy that is released during breakdown of the glucose and the other organic fuel molecules that are from the carbohydrates with fats and the proteins in the glycolysis is just captured and then stored in the ATP.
During the cellular respiration the glucose is just broken down in presence of the oxygen in order to just produce the carbon dioxide with water. Energy that is just released during reaction is just captured by energy-carrying molecule that is ATP (adenosine triphosphate).

On Monday afternoon, Arun has keyboard practice session in his school auditorium. He crosses his school playground and enters the cool and dark auditorium. Initially he is unable to see anything. But after sometime he is able to make out the way between the rows of seats. During this time, in his eyes.
Answer:
The correct answer would be - pupils expand or become bigger so more light can enter the eyes.
Explanation:
When Arun crosses the playground he was in a warm and sunny condition where light is more than required so the pupil becomes small in an excess light condition.
So, that less light can enter the eyes and when he enters into a dark auditorium then less light enters in his eye and he can't see a thing and pupil expands and more light enters the eye enabling to see and able to make out the way between the rows of seats
A classmate explains that igneous rocks can be changed to metamorphic rock by first being melted into magma and then cooling. What correction needs to be made to this statement?
Answer:
Cooled magma becomes igneous rock
Explanation:
Took the quiz
Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.
What are rocks?There are three different types of rocks: metamorphic, sedimentary, and igneous. These rocks can all alter. In actuality, any rock may transform into any other kind of rock.
Condensation and cooling: The Earth's interior can experience temperatures hot enough to produce magma. Igneous rock is created as crystals develop in the cooling magma.
If the lava cools gradually, as it does if it stays inside the Earth for an extended period, the crystals enlarge. The crystals will be very tiny if the magma cools quickly. Crystallization is the process by which crystals emerge from magma.
Therefore, Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.

In which part of the water cycle does the sun heat up water and turn it into water vapor?
A) Collection
B) Evaporation
C) Precipitation
D) Runoff
Answer: B
Explanation: The sun interacts with the ocean
Water at the ocean's surface is heated by the Sun. The molecule of liquid water change into water vapor with enough energy. The process is called evaporation. Water in the oceans is lost because of energy from the Sun.
What is the role of the sun in the water cycle quizlet?
The sun's warmth causes the water on the Earth's surface to evaporate, or change from a liquid water to a water vapor or gas.
The sun and gravity play a role in the water cycle
Water is transported around the globe by ocean and atmospheric circulation. The precipitation falls from the clouds to the land through the Watersheds.
Is the water cycle driven by the sun?
The water cycle is powered by the sun's energy. The sun warms the water in the oceans, lakes, and seas. In a process called evaporation, the water changes from liquid to vapor.
What effect did the sun have on the water?
The water cycle is dependent on the sun. The sun provides most of the heat and energy on Earth. Liquid and frozen water evaporate into water vapor gas, which rises high in the sky to form clouds that move over the globe and drop rain and snow.
The major source of energy in the water cycle is the sun
The energy from the sun is what drives the water cycle. Water from the oceans, lakes, rivers, and even the soil is converted into solar energy. transpiration moves water from plants to the atmosphere.
The quizlet is caused by the energy from the sun
There is water in the air. Energy from the Sun causes liquid water to evaporate. Liquids change to the gas state during evaporation. You just studied a few terms.
The puddle is part of the water cycle
Clouds form in the atmosphere of the water that is in a continuous cycle. Water accumulates into a puddle. Evaporation occurs when the sun dries up the puddle. turns into liquid.
What is happening in the water?
The water cycle shows the movement of water. In the form of rain and snow, liquid water falls into water vapor and condenses to form clouds. Water moves through the atmosphere.
Is water attracted to the sun?
Dark surfaces, water and metal absorb sunlight.
The sun's heat and light affect the environment
Earth would be frozen solid without the Sun. Most living things rely on the steady light and heat of the Sun. Liquid water is possible because of the Sun's heat.
How does the sun light up?
Nuclear fusion takes place when the sun's core is very hot and there is a lot of pressure. Nuclear fusion creates heat and light. Our planet is warm enough to support life because of the amount of solar heat and light.
If there was no Sun, what would happen to the water cycle?
Water is constantly moving around the Earth. This is dependent on the Sun's energy. Without the Sun there would be no water cycle, which means no clouds, no rain, and no weather.
How does the sun affect the weather?
A new study suggests that solar variations affect the amount of clouds. Large eruptions on the surface of the Sun can temporarily shield Earth from so-called Cosmic rays which now appear to affect cloud formation.
The Sun is important in the occurrence of atmospheric processes
The weather and the sun. Our changing weather is caused by the energy that the Earth receives from the Sun. Large and small weather systems are warm by solar heat. There are obvious causes and effects of the day-night and summer-winter weather cycles.
The effect of heat?
There are milder effects of heat and health. The effects of heat stroke are severe. This is a serious illness. Body temperature can go up to 105F and can be accompanied by convulsions, coma and even death.
What happens when warm water is blown over land?
The circulation is caused by the low pressure over the warm land and the high pressure in the cool air. The high pressure in the cool air takes the place of the warm air in the low pressure which causes the air to move and wind is formed.
The water cycle has seepage
Water enters the soil from the ground. Seepage is when water slowly moves through soil and rock before being stored underground.
The water cycle has a main source of energy
Credit: NASA.
The water cycle has two main sources of energy
The heat and light of solar energy can cause water to melt or evaporate in the water cycle.
The water cycle requires heat energy from the sun
