what are 5 functions of carbohydrates ​

Answers

☁️ Answer ☁️

PROVIDES INSTANT ENERGY TO THE BODY:

This appears to be the primary function of carbohydrates in the body.

Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.

RESERVE FOOD:

Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.

CARBOHYDRATES FORM OTHER BIOMOLECULES:

Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.

DETOXIFICATION OF THE BODY BY METABOLISM:

Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.

SPARING PROTEIN

In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.

What is the central nervous system?

The brain and spinal cord make up the central nervous system. The brain directs our thoughts, memories, movements, and emotions. Between the brain and the nerves that run throughout the body, the spinal cord relays messages.

It regulates cognition, personality, memory, emotion, speech, and the capacity to feel and move. The corpus callosum, a band of nerve fibers in the middle of the brain, connects the left and right hemispheres of the brain.

Thus, the central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.

Answers

Answer:

look,Examples of X-linked recessive conditions include red-green color blindness and hemophilia A: Red-green color blindness. Red-green color blindness means that a person cannot distinguish shades of red and green (usually blue-green), but their ability to see is normal.

Red-green colorblindness is an X-linked recessive disorder in humans.

What do you mean by disorder?

An illness that disturbs the normal physical or mental functions of any individual.

The allele of colorblindness resides on X-chromosome, which means the male is affected with one mutant allele. while both the alleles are required to be mutant to cause the disorder in females. Another example of X-linked disorder includes Hemophilia. Red-green colorblindness reveals that an individual cannot able to differentiate the shades of red and green but occupy the normal vision.

Therefore, Red-green color blindness is an X-linked recessive disorder in humans.

The phase of mitosis which is shown below in the picture is Anaphase. During this phase, chromosomes break at centromeres.

What do you mean by Mitosis?

Mitosis may be defined as a process where a single cell divides into two identical daughter cells.

Anaphase is the phase of mitotic cell division where chromosomes break into chromatids that are separate from each other and are pulled towards the opposite pole with the help of spindle fiber.

The strangler fig is a vine that starts out as a seed in the tree canopy of the rain forest. It drops its roots down from the canopy to the forest floor. By sprouting in the rain-forest canopy, the strangler fig seedling is exposed to more-

The strangler fig plant shows an aggressive growth habit as an adaptation that allowed its growth. It drops to the forest floor and develops its seeds by exposure to sunlight. Thus, option A is correct.

What are adaptations?

Adaptations are a crucial part of the evolutionary process that allows the organism to fit and survive in altered environmental conditions. It has been due to the process of natural selection that gets inherited.

The aggressive growth habit of the strangler fig vine is to ensure its survival in the rainforest covered in canopies. The seed of the plants uses sunlight and nutrients to grow at a faster rate and hangs their roots on the first floor. The sunlight increases its rate of germination.

Therefore, option A. sunlight is used for germinating the fig seeds.

n= 1 ------ 2 electrons

n = 2 ----- 4 electrons

n =3 -----  0 electrons

n = 4 ----- 0 electrons

Carbon has the electronic configuration; 1s2 2s2 2p2.

This means that there are only two electrons in the n-1 level and there are four electrons in the n=2 level.
