explain why air exhaled during exercise contains more carbon dioxide than exhaled at rest
Answer:
In addition, the blood contains some carbon dioxide (a waste product) that is transferred to the air in the lungs, which is then exhaled. The result is that the exhaled air contains less oxygen and more carbon dioxide than the inhaled air.
You will exhale more CO₂ during exercise because the body consumes more glucose and oxygen during exercise than when at rest.
During exercise the body require a lot of energy than usual hence more calories( glucose ) are burnt with oxygen to provide such energy therefore releasing more CO₂ as waste product , therefore you will exhale more CO₂ while exercising.
Hence we conclude that it is because the body consumes more glucose and oxygen during exercise than at rest.

A person lives on the Tropic of Capricorn. What is the altitude of Polaris?
O 23 1/2"
O 90°
O 66° 33"
O 15°
O 30°
O 45°
The correct answer as to what the altitude of Polaris would be for a person that lives on the Tropic of Capricon is 23° 1/2".
Polaris is a star and the altitude of any star is its height above the horizonThe Polaris is otherwise known as the North star as an indication that it is directly located overhead the north pole. Thus, it may not be visible once one moves South of the equator. The tropic of Capricon is located approximately 23° 1/2" South of the equator. In other words, the latitude of the Tropic of cancer is approximately 23° 1/2".Hence, the altitude of the Polaris at an altitude of 23° 1/2" will also be 23° 1/2", although it will most likely remain invisible.A person that lives on the Tropic of Capricon is approximately on latitude 23° 1/2". Since the altitude of a star is its height above the horizon, the altitude of Polaris from the Tropic of Capricon would, therefore, be 23° 1/2"

what is the concept that organisms can only come from other organism called
The concept that organisms can only come from other organisms is called biogenesis.
The concept of biogenesis has to do with the belief that organisms cannot just arise spontaneously from non-living objects or sources, but can only arise from another living organism through the process of reproduction.
Biogenesis is as opposed to abiogenesis. The latter is a concept that opines that organisms can arise spontaneously from non-living sources without any reproduction.

What is a cell?
Cell is the basic unit of living bodies. A cell contains a nucleus, cell membrane, lysosomes, Golgi bodies etc.
Nucleus regulates all the functions of a cell as brain do in our body. Cell membrane helps to transport ions inside the cell as Golgi bodied do.
Mitochondria provide the energy and produce the chemicals needed for all chemical processes in the cell as liver do in our body.
Therefore, nucleus and brain matches in function and cell membrane and Golgi bodies matches in function. Similarly mitochondria and liver marches as well as cytoplasm and skin matches in functions.

Answer:
The Correct answer is DNA is transcribed into RNA which is translated into protein
Explanation:
The genetic information is unidirectional, from DNA to proteins. First, DNA is transcribed into an intermediary RNA molecule is known as transcription (TC), a further messenger RNA molecule (mRNA) is translated into a corresponding sequence of amino acids (translation). This concept of information flow is known as the central dogma of molecular biology.

Tell me everything about carbohydrates
Answer:
Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products. Though often maligned in trendy diets, carbohydrates — one of the basic food groups — are important to a healthy diet.
"Carbohydrates are macronutrients, meaning they are one of the three main ways the body obtains energy, or calories," said Paige Smathers, a Utah-based registered dietitian. The American Diabetes Association notes that carbohydrates are the body's main source of energy. They are called carbohydrates because, at the chemical level, they contain carbon, hydrogen and oxygen.
There are three macronutrients: carbohydrates, protein and fats, Smathers said. Macronutrients are essential for proper body functioning, and the body requires large amounts of them. All macronutrients must be obtained through diet; the body cannot produce macronutrients on its own
Explanation:
recommended daily amount (RDA) of carbs for adults is 135 grams, according to the National Institutes of Health (NIH); however, the NIH also recommends that everyone should have his or her own carbohydrate goal. Carb intake for most people should be between 45% and 65% of total calories. One gram of carbohydrates equals about 4 calories, so a diet of 1,800 calories per day would equal about 202 grams on the low end and 292 grams of carbs on the high end. However, people with diabetes should not eat more than 200 grams of carbs per day, while pregnant women need at

There exist different levels of organization in nature, which go from the smallest things like atoms, to the most complex systems like ecosystems. In the exposed situation, the correct increasing order is Organelles, cells, tissues, organs, systems.
------------------------------------
According to the composing elements, we can find many different organization levels in nature.
Organelles: These are molecular subcellular structures that carry out one or more specific functions in the cell. Cell: Molecules get grouped in living cellular units that have auto replication capabilities. It is the smallest structural unit capable of functioning by itself. A cell is capable of communicating with other cells. When they receive signals from the exterior, they respond in varying ways. Their membranes delimitate them and protect them, constituting a selectively permeable barrier. Cells There are different cells with different sizes, shapes, and forms.Tissue: A tissue is the organization and association of the same type of cells. Each tissue performs different functions. These tissues can be epithelial, adipose, nervous, muscular, and etcetera. Organ: An organ is composed of different tissues that work together in a more complex function. Tissues form structures such as the heart, lung, kidney, brain, and etcetera. Each organ has its function. Systems: When different units -organs or individuals- get associated and work together, they become a system. By working together stably, these associated units maintain homeostasis.-----------------------------------------
