Question is incomplete. Complete question is as follows:

The ____ abuts the lumen of the alimentary canal and consists of epithelium, lamina propria, and muscularis mucosae.

Answer:

Mucosa

Explanation:

Mucosa or mucosal membrane forms the lining of many cavities in the body like the alimentary canal and also covers many internal organs. It lines reproductive, digestive and respiratory system. In the gastrointestinal tract the mucosa is made of three layers: epithelium, lamina propria and muscularis mucosae.

The epithelium of mucosa is made of simple columnar epithelium cells. It consists of many types of cells like parietal cells (secrete HCL) and foveolar cells (secrete mucus). Lamina propria is a loose connective tissue present beneath the epithelium. It provides nutrition and support to epithelium. Muscularis mucosae has smooth muscle fibers which helps the glands on the surface to secrete their contents and also increase the contact between contents of lumen and epithelium.

If you submerge a mussel in an environment in which the ambient osmotic pressure progressively increases, the blood osmotic pres

bezimeni [28]

Answer:

The correct option is 'a'

If osmotic pressure increases when a mussel is submerged in the water,the blood osmotic pressure also increases.

Explanation:

Mussels are bivalves that are found in fresh water as well as marine water.

They have bluish blood and small heart pumps the blood.Some mussels have red blood which contain hemoglobin that carry oxygen rather than hemocyanin.

The mussels show increase in blood chloride level and amino acid when the osmotic pressure of the water increases.

Submerging the mussel in the aquatic environment increases osmotic pressure of the mussel.

Where does nad+ deliver electrons compared to fad in cellular respiration?

Anna71 [15]

Answer:

The correct answer would be "NADH delivers its electrons to complex I and FADH₂ deliver its electrons to complex II" in cellular respiration.

There are mainly four complexes associated with electron transport chain of cellular respiration.

Complex I or NADH: ubiquinone oxidoreductase is the complex at which NADH is oxidized to form NAD⁺. The free electrons are transported with the help of ubiquinone.

Complex II or succinate dehydrogenase is the complex associated with oxidation of FADH₂ to FAD⁺. It also transports the free electrons with the help of the ubiquinone pool.

Complex III or cytochrome bc1 complex transport free electrons from ubiquinone to the cytochrome C which is a water-soluble electron carrier.

Complex IV or cytochrome c oxidase transport the free electrons to oxygen to form water.
