Answer:Through polymerization reactions.
Explanation:
This happens when monomers bond together to form a polymer.
There are several ways;
The Skeletal system protects for example the heart and several aspects of large vasculature. The skeleton also has the means to produce blood cells in the marrow of some of the bones.
Answer:
The carbon cycle refers to the procedure in which the atoms of the carbon are recycled again and again on Earth. Carbon recycling occurs within the biosphere of the Earth and between the nonliving environment and living things.
In case if I were a carbon, then I would have originated from fossil fuels and left the ground, through the process of photosynthesis I would have entered the trees, I would have consumed by animals, even I would have released from some of the trees or plants that dies, I would have also released from animals by the process of decomposition after their demise, and animals can even breathe me in out by the process of respiration.
Explanation:
Answer:
A) The radial orientation of cellulose microfibrils in the cell walls of guard cells causes them to bow outward and open when the stomatal pore when turgid.
Explanation:
Stomata are pores on the surface of leaves that work as valves controlling the gas exchange in plants; they are bordered by a pair of curved guarded cells in charge of opening and closing by increasing or decreasing the stomatal pore area.
Guard cells walls structure consist of a combination of stiff cellulose microfibrils oriented along the circumference of the cells and a softer matrix material which makes it possible for stomata pore to open by increasing water pressure (turgor).
Option B states that when guard cells become turgid, they close the stomata. This is a false statement as we explained before.
Option C states that light (known stimulant for opening stomata) causes guard cells to become flaccid which is also false. Guard cells become turgid in order to open the stomatal pore.
Option A is correct.
