1 answer:
Alex787 [66]3 years ago
6 0

Answer: Options are not given, here are the options.

a.Thylakoid membranes become more permeable to ions

b.The chlorophyll breaks down

c.The peripheral proteins lose their ability to bind to the transmembrane proteins

d.Water cannot bind to PSII to form oxygen

The correct option is C.

The peripheral proteins lose their ability to bind to the transmembrane proteins.

Explanation:

In photosystem 11, it is the center where light is converted to moving electrons. When the chlorophyll molecule absorb light, the electrons gain energy.

Increase temperature affects the activity of photosystem 11 because the peripheral protein lose their ability to bind to the transmembrane protein which is as a result of high temperature affecting the surface of ionic interactions which is for binding to transmembrane protein.

Why do greenstick fractures commonly occur in children? Their bones contain higher amounts of collagen. Their bones contain high
Alisiya [41]

Answer:

This traumatic pathology occurs in children because the concentration of minerals is lower in children, since these have a greater collagen fibrillar organic structure, which is what gives children greater elasticity during bone growth until the areas close. proliferative.

The denomination in green stem comes from the analogy between this type of fracture and the one that occurs when trying to break the green stem of a plant.

It is characterized by being an incomplete fracture, with rupture of the periosteum and cortical bone on the convex side of the bone, while in the concave area the periosteum does not break, as a consequence the bone is not completely broken (incomplete fracture), but the fragments move and present an angulation of variable amplitude that needs to be corrected

Explanation:

To be more specific, these fractures occur more up to ten years of age, according to some research.

The centers of bone proliferation and differentiation where osteochondral mineralization of long bones occurs is what confers greater flexibility and greater organic content in the long bones of children.
