Answer:
Transpiration:
Losing the water absorbed by the plant through its aerial parts in the form of water vapor to the atmosphere. Water is absorbed by roots from the soil and transported as a liquid to the leaves via the xylem to mesophyll cells, through intercellular spaces, and moving through substomatal space to the stoma. The leaves and aerial parts have small pores that allow water to moves as a vapor.
Advantages:
With the transpiration exchange of gases also takes place.
Excess amount of water removed from the plant body.
Absorbing water and distribution of water among plant body parts
Cooling the exposed aerial parts of the plant to the sun and warm winds.
The osmotic balance of the plant cell is regulated by the process of transpiration.
The logical sequence in order to loss of water due to transpiration is as follows:
xylem, mesophyll cells, intercellular spaces, substomatal space, stoma.

Answer:
Depolarized graded potential.
Explanation:
A depolarizing graded potential is a local change in the membrane potential that makes a small increase in the potential. The membrane potential is less negative because the graded potential caused the entrance of Ca²⁺ or Na⁺ ions to the inside of the cell decreasing the negative voltage in the inside of the cell.
Answer:
The earth system is itself an integrated system, but it can be subdivided into four main components, sub-systems or spheres: the geosphere, atmosphere, hydrosphere and biosphere. ... The atmosphere receives energy from solar radiation which warms the earth's surface and is re-emitted and conducted to the atmosphere.
Answer:
Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
