Answer:
Plant tissues have several types of cells i.e vessel elements and tracheids (in xylem),sieve tube cells and companion cells (in phloem) ,parenchyma cells,collenchyma cells and sclerenchyma cells.
Explanation:
Xylem is made up of vessel elememts and tracheids.
Vessel elements have thick secondary cell walls.They lack end walls and join together to form long tubes.
Tracheids are slender cells with overlapping ends.
Phloem is made up of sieve tube cells and companion cells.
Sieve tube cells are long and their end walls have small pores.
Companion cells make proteins for sieve tube cells.
Parenchyma cells are spherical but flat at point of contact.They have thin primary cell walls and have large vacuole for storage of food.In leaves they are called mesophyll cells and are the sites for photosynthesis.In other parts they are sites of respiration and protein synthesis.
Collenchyma cells are fexible and function to support the organs in which they are found.
Sclerenchyma cells contain rigid secondary cell walls.Their cell walls are hardened with lignin which is the main chemical component of wood.
If the temp.rises then it will lead to excessive evaporation in hydrosphere, on lithosphere it willl cause extreme hot conditions and with the scarcity of water the animals, birds will die and also plants will be affected.Hydrosphere and lithosphere are included in biosphere so it willl altogether effect biosphere...

The answer would be <span>1.bicarbonate ions 2.acidic chyme
Pancreas juice is made of various enzyme and bicarbonate ions. The role of bicarbonate ions is to neutralize the acid that produced by the stomach. The acid is dangerous because it can damage the intestine wall and the enzyme produced.
The pancreas doesn't produce bile salt or </span><span>hydrochloride(HCl).</span>
Bioremediation is that process which use the biological organisms to protect and repair the environment.
Bioremediation refers to the use of biological agents or processes in order to protect and repair the environment from negative human impacts. This phenomenon depends on stimulating the growth of specific type of microbes that utilize contaminants such as oil, solvents and pesticides as a sources of food and energy.
These microbes has the ability to use these harmful substances as a food and convert these contaminants into water as well as harmless gases like carbon dioxide so we can conclude that bioremediation is that process which use the biological organisms to protect and repair the environment.
