<span>They lose the ability to gain nutrients.
Hence, people with celiac disease cannot tolerate gluten. Gluten is a type of protein found as nutrient in food and is released to the digestive system. When the body receives food that contains gluten (e.g. wheat, rye, and barley) the immune systems responds and attacks the small intestines. In the event of this, the linings of the small intestine called villi are damaged. When the villi get damaged, the body cannot properly absorb nutrients. </span>
There are two types of alveolar cells. The type I alveolar cells which lines the alveoli and much more abundant than type II alveolar cells. Then the type II alveolar cells lesser in number but functions differently than type I alveolar cells. Type II alveolar cells secrete surfactant (composed of lecitin and sphingomyelin) for the lungs. Surfactant reduces the surface tension inside the alveoli, preventing alveolar consolidation. This is important as babies with dysfunctional type II alveolar cells (usually preterm babies less than 32 weeks age of gestation) will have respiratory distress syndrome in the absence of surfactant.
The correct answers A false
Answer:
Explanation:
Chemical cycles typically involve three general steps: ... As organisms die, decomposers break them down, further supplying the soil, water, and air with chemicals in inorganic form. The producers gain a renewed supply of raw materials for building organic matter, and the cycles continue.
Two nucleotides on the same strand form a <u>Phosphodiester bond </u>while two complimentary bases on opposite strands form <u>Hydrogen bonds</u>. An a-t base pairing forms <u>2</u> such bonds.
The constituent components that make up DNA's double-helix structure are known as nucleotides. Each nucleotide has a base in it. The four various colors you see here stand for the four different bases that might be used. Between nucleotides, a unique kind of covalent link known as a phosphodiester bond occurs. The two strands of DNA are formed by these phosphodiester linkages.
Hydrogen bonds are the bonds that develop between base pairs. Thymine and adenine make two hydrogen bonds, and guanine and cytosine form three hydrogen bonds. Therefore, we have concluded that hydrogen bonds are the type of binding that develops between base pairs in DNA to hold the two strands of a double helix together.
