What will most likely happen if a person does not consume the minimum daily requirement of carbohydrates?

Answers

If a person does not consume the minimum daily requirement of carbohydrates then the body will use stored glycogen and the person will look unhealthy and become weak after some time.

Importance of carbohydrates: Like other nutrients, carbohydrates are also very essential for various functions of the body. Carbohydrates such as glucose are required for instant energy and day-to-day activities. If there is no or less amount of carbohydrate in the body then our body will start converting the glycogen that is stored in the liver into glucose. After some time, the person will start to appear unhealthy, thin and weak if there is no minimum daily requirement of carbohydrates is met.

Thus, the correct option is A.

What are Proteins?

Proteins may be defined as intrinsically appearing, a remarkably complicated substance that consists of amino acid residues united by peptide bonds.

The primary structure of the protein is so simple and it looks like a linear chain of the polypeptide. The secondary structure of proteins consists of alpha-helix and beta-pleated sheet that involves the twisted form of polypeptide chains.

The tertiary structure of the protein is more complicated as compared to secondary and primary. This structure emerges due to the constant folding of polypeptide chains.

Option D is the correct answer

In this investigation, you will observe the release of O2 and CO2 into the environment. Gas production by two types of organisms will serve as evidence of photosynthesis and cellular respiration in action. In part 1, you will vary the amount of sugar present and observe the effect on cellular respiration.

Answers

Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen).

During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise. As byproducts, carbon dioxide and water are produced.

What are the three stages of cellular respiration?

The Krebs cycle, oxidative phosphorylation, and glycolysis—an anaerobic process—are the three phases of aerobic cellular respiration.

All forms of cellular respiration begin with glycolysis, which is anaerobic and oxygen-free. The pathway will go on to the Krebs cycle and oxidative phosphorylation if oxygen is present. However, some species may engage in fermentation to continuously manufacture ATP in the absence of oxygen.

Total amount of ATP molecules generated during aerobic respiration from a single glucose molecule.

During glycolysis:

As 2ATP

From 2NADH 5ATP (oxidation phosphorylation)

In pyruvate oxidation;

From 2NADH 5ATP (oxidative phosphorylation)

Citric acid cycle;

Transmit Absorb Frequency Light Energy Reflection Transparent

(image attached)


thank you!! WILL GIVE BRAINLIEST!!

Answers

Answer:

Transmit - cause (something) to pass on from one place or person to another.

Absorb - take in or soak up (energy or a liquid or other substance) by chemical or physical action.

Frequency - the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.

Light Energy - Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun.

Reflection - the throwing back by a body or surface of light, heat, or sound without absorbing it.

Transparent  - (of a material or article) allowing light to pass through so that objects behind can be distinctly seen.

Answer:

In the photo to the left, we can see a red tomato. This tomato appears red because of how it is interacting with the light energy it is receiving. It is reflecting red, and absorbing all other colors: orange, yellow, green, blue, and violet. In this depiction, you can see an entire rainbow of colors going into the apple and only red coming/bouncing (reflecting) back off. You can also see the green of the stem, which is colored in the same way. It absorbs certain frequencies of light--all other colors of light than green--and reflects certain frequencies of light, green light.

In this image, we are able to see the apple and stem because the air/medium that we are seeing this image through is transparent. If the surroundings were opaque, we wouldn’t see red at all (all colors would be blocked if light is blocked).

Another transparent factor in this image are light waves. Actual lightwaves (unless they are being refracted in such a way that they are being spread out--like a laser beam hitting a spray of water mist) are transparent.

You wouldn’t be able to see the [red] lightwaves bouncing off, you would only see the red of the apple. When light is being refracted by a different translucent material--such as glass, plastic, and water--that material is also transmitting the light, it is passing on the light wave. This is when refraction/the bending of light due to a change in media occurs.

A parasite that frequently infects a particular species of mosquito that feeds on people can result in the serious and occasionally fatal disease known as malaria. Malaria often causes severe disease, including high fevers, shivering chills, and flu-like symptoms. Humans can contract four different types of malaria parasites: Falciparum Plasmodium, P.

Female Anopheles mosquitoes carrying the Plasmodium parasite bite people to feed their own eggs, which is how the parasite is propagated. An infected mosquito injects sporozoites, or early stages of the parasite, into the host's bloodstream while it consumes its prey (often between twilight and sunrise). The sporozoites are transported by the blood to the liver, where they develop into schizonts, which are a type of parasite. Each schizont multiplies into thousands of merozoites throughout the course of the following one to two weeks. The merozoites escape the liver and re-enter the bloodstream where they assault red blood cells, continue to grow and divide, and eventually kill the blood cells.
