The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.
<h3>What is Active transport?</h3>
Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.
During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.
But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.
The complete question is as follows:
What part of the body uses active transport to take up nutrients after concentration has reached equilibrium?
- Lungs
- Stomach
- Small intestine
- Liver
Therefore, the correct option for this question is C, i.e. small intestine.

<span>When organisms are born in the wild, they tend to start developing an understanding of their surroundings based on their experiences. If an organism is transplanted to a different environment right after birth, it will develop the instincts to survive in that environment. A sudden change in its environment will result in the organism being out to place, possibly unable to cope with the selection pressures of its new environment. This will likely be the case with these guppies. This issue with transplantation is very real with animals born in captivity, which is why many are put through simulation exercises such as hunting and hearing the calls of predators, so that they may be able to survive in the wild, when transferred.</span>
Answer: Rosalind Franklin
Explanation: Rosalind was the first oerson to get a picture while Watson and Crick came up with the strusture and won the nobel piece prize
What’s the smallest muscle in the human body?
The stapedius, in your middle ear, measures about 1mm in size (or
1/26 of an inch). Connected to the stapes bone, it contracts to pull
back the stapes and help protect your inner ear from loud noises. The
stapedius also contracts to keep your own voice from sounding too loud
in your head.
What’s the smallest bone in the human body?
Conveniently, that would be the stapes. It is one of three tiny bones
in the middle ear that convey sound from the outer ear to the inner
ear. Collectively called the ossicles, these bones are individually
known as the malleus, incus, and stapes. Those are Latin words for the
shapes the bones resemble: a hammer, anvil, and stirrup.
What’s the smallest organ in the human body?
You’ll find the pineal gland near the center of the brain, in a
groove between the hemispheres. It’s not an organ like those in the
abdominal cavity. It’s the human body’s smallest endocrine gland, and it
produces melatonin, a hormone (derived from serotonin) that affects how
we sleep, wake up, and react to seasonal changes. It’s called pineal
because it’s shaped like a little pinecone.
What’s the smallest blood vessel in the human body?
<span>Capillaries, the smallest, thinnest-walled blood vessels in the body,
connect veins and arteries. They can be as small as 5-10 micrometers
wide — or 50 times thinner than a baby’s hair. Each of us contains about
10 billion of them, with the average adult body containing about 25,000
miles of capillaries.</span>
Answer: B (Color blindness)
Explanation:
Typical red-green color blindness in human patients is caused by mutations on genes located in the X chromosome. These mutations act in a recessive manner. Since females have two X chromosomes, the presence of a mutation in a single one of them does not normally result in color blindness. Males, in contrast, have a single X chromosome and therefore the presence of a mutation is likely to cause the disease.
About the other options: Down‘s syndrome is a numerical chromosomal anomaly, not related to sex. Human blood type is a codominant trait. Finally, tail length in dogs is a polygenic trait not amenable to classic Mendelian analysis.
