D. Bacteria because “bacteria” is actually a domain itself
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.
Answer:
The correct answer would be b. because water provides electrons.
During the light reaction of the photosynthesis, the water is photolysed into high energy electrons, hydrogen ions, and oxygen.
The overall reaction can be written as:
2 H₂O + sunlight → 4 H⁺ + 4 e⁻ + O₂
It takes in water-splitting complex associated with photo-system II rooted in the thylakoid membrane of chloroplast.
The oxygen is released as the byproduct of photosynthesis.
The hydrogen ions help in the formation chemiosmotic potential across the thyllakoid membrane which help in the formation of ATP (adenosine triphosphate).
The electrons are used to replace the electrons lost from chlorophyll a of reaction centre associated with photo-system II. The electrons are lost due to the photo-excitation of chlorophyll a.
The electrons lost from chlorophyll a help in the production of ATP and are used to reduce NADP⁺ into NADPH.
The ATP and NADPH are used in light-independent reaction of the photosynthesis to produce glucose or food.
It is the 1st one because it looks right
b. Angiosperm
Explanation:
Acorn is the fruit of oak tree. It is a nut and bears only one seed.
Since the scientist finds that the fruit produced on the tree is a nut then it is obviously an angiosperm because:
The only groups of seeded plant are Gymnosperms and Angiosperms.
Gymnosperms produce cones and have naked seed.
The seed produced within a fruit is a characteristic of angiosperm.
