The angle of rotation about the blank bond is referred to as ϕ (phi) and that about the blank bond is called ψ (psi).These angles describe the blank conformation of any particular residue in any protein, and allow one to predict whether a combination of amino acids in a polypeptide will be able to form and maintain blank. conformation of any particular residue in any protein, and allow one to predict whether a combination of amino acids in a polypeptide will be able to form and maintain blank.Proline is not able to blank the ideal ϕ and ψ angles for an α helix, owing to the presence of the rigid imidic group as its side chain.Furthermore, proline does not have an blank that acts as a stabilizing blank in the middle of the helix. As a consequence, the secondary structure is predicted to be blank..

Terri lost her water bottle while hiking in Canada it was a hot day so she drank water from a stream to stay hydrated a few days
hammer [34]

Answer:

She got infected through the water she drank at the stream.

Explanation:

Protozoa is a type of pathogenic microorganisms.

Giardia are flagellate protozoa that cause the disease called giardiasis. The parasites enters the body through ingestion of contaminated food or water The food or water are usually contaminated by the feces of infected people or animals.

The protozoa attach to the lining of the host’s small intestine, where they prevent the host from fully absorbing nutrients. They may also cause diarrhea, abdominal pain, and fever.

The symptoms in the question above points to a likelihood that Terri’s sickness was caused by a Giardia protozoa.

Determine whether each example represents continental drift or sea floor spreading.
laila [671]

Answer:

Sea floor spreading-> <u><em>Oceanic ridge and Magma pushing two plates apart</em></u>

Continental drift-> <u><em>Concept of pangaea and Oceanic plates sliding under continental crust</em></u>

Explanation:

Due to the divergent plate movement, the magma come out to the surface, forming the mid oceanic ridge and this separation of plates on the sea floor is known as the sea floor spreading. The magma here pushes the two plates to move apart because of the convection current that generates in the mantle. One example of mid oceanic ridge is the Mid-Atlantic Ridge.

  Continental drift refers to the slow and gradual movement of the lithospheric plates over the viscous asthenosphere layer. This motion of continents takes place because of the plate tectonic movement. Due to this plate motion, the denser plate gets subducts beneath the less denser plates. For example, the oceanic crust when collides with a continental crust, it gets subducted because of its higher density. The great supercontinent "pangaea" also formed and separated due to this plate motion.
