it protects the seed against any damage or harmful weather conditions and also helps in dispersal of the seed through different means.
It's actually A. Vertebrate have a hard out shell.
The viscosity of water is the thickness of water (it might also be considered the stickiness when talking about other fluids). Water has many properties, and the viscosity of water influences in many of them. We can take the surface tension of a liquid as an example. The more viscous a substance is, higher will the surface tension be and vice versa since there will be a higher and lower attraction between molecules respectively.
→ The surface tension of water is something really important since it contributes in many ways to the environment and if you think about it, if the water was a little less viscous, there wouldn't be water since the viscosity of water makes it resistant to evaporation to a certain degree.
Hope it helped,

Photorespiration or oxidative photosynthetic carbon cycle or C2 photosynthesis is a process in which enzyme RuBisCO oxygenates RuBP that leads to wastage of some energy formed during photosynthesis. This process involves three organelles chloroplast, peroxisomes and mitochondria.
Photorespiration occurs in dry and hot climatic plants when there is more oxygen in atmosphere than carbon dioxide. It is a light dependent process where glycolate is synthesized.
The plants have minimized its occurrence because it is a wasteful process. In photosynthesis carbon dioxide is used while in photorespiration carbon dioxide is releases. Thus, these processes work against each other so the plants minimize its occurrence.
