The walls of the small intestine are folded by what?

Biology

stiks02 [169]3 years ago
6 0

The small intestine is the part of the gastrointestinal tract where the absorption of nutrients and minerals occurs. Because of that, surface of the small intestine needs to be increased. The inner wall (mucosa) is lined with epithelial tissue and covered with folds called plicae circulares. From the plicae circulares extend finger-like pieces of tissue called villi. The individual epithelial cells of mucosa also contain finger-like extensions-microvilli. Thus, plicae circulares, villi and microvilli are structures that improve absorption by increasing the surface of small intestine.

Answer:

B. The rating number means it will  protect you that many times  longer than without sunscreen

Explanation:

The sun protection factor is a comparison between the length of time it will take for a skin that has no sunscreen to begin reddening compared to a skin with sunscreen applied. Therefore, the ratings is an indication of the length of time a person will be protected from ultraviolet rays than when the individual has no sunscreen applied.

While higher SPF's are believed to offer more protection against UV rays, the added protection is usually just a negligible amount. They are very important for the skin and protect the body against diseases like cancer.

What is the potential energy in the thylakoid membrane used for?
liubo4ka [24]

The right answer is to perform photosynthesis (more precisely to convert ADP to ATP by ATP synthase).

Light comes to us in the form of photons. These photons have a different energy potential depending on their wavelength.

When a pigment picks up a photon corresponding to its absorption capacity, one of its electrons goes into the excited state. This energy can be transmitted in 3 ways: either by spreading it in the form of photon or heat; both ways lose energy. The third is to transmit resonance energy and there is almost no loss of energy.

A photosystem consists of a reaction center and a collector antenna to optimize the absorption of photons triggering photochemical reactions in order to operate the ATP synthase to produce ATP in the presence of a hydrogen gradient.
