<u>Answer:</u>
The Earth has got its tilted axis and this is the reason for different seasons to be formed. Communities are a set of population found in that particular area and are of two types.
A) Terrestrial (Land)
B) Aquatic (Water).
These communities to flourish need a perfect environment with a perfect season. Hence according to the season formed due to the tilted axis influences the terrestrial community which forms in that particular region and have the ability for the region specific community growth.
The terrestrial community of a tundra or desert or rain forest all depends on the particular season that can be formed due to the position of the earth facing the sun.
The outer layer of the skin is called the epidermis. This layer is formed by epithelial cells. The dead layer of cells is called the stratum corneum.
Answer:
Adenosine triphosphate or ATP is the energy-providing molecule of the organisms which produce energy during the metabolic process. Therefore this is also considered as the energy currency of the cell.
As a biomolecule, it is made up of three components: a ribose sugar, adenine nitrogenous base and three phosphate groups. Its adenine base is attached to the 9th nitrogen atom of the 1′ carbon of the sugar. and three phosphate group are attached to the 5' carbon atom of the sugar.
High energy is stored in the three phosphate bonds which when broken down to adenosine diphosphate and monophosphate releases energy. New ATP is generated through the process of phosphorylation in mitochondria and chloroplasts in plants. The ATP production reaction is catalyzed by ATP synthase
Hello
The pH range of tolerance for humans is well defined and very small for a number of reasons.
First, we must understand that all biological reactions in our body are carried out by biological catalysts called enzymes. These enzymes operate under specific pH and and temperature conditions. Deviation from these conditions will result in inefficiency of the enzymes' functions. This may be observed macroscopic-ally as poor digestion among other things.
Next, an equilibrium is necessary for the movement of CO2 in red blood cells. CO2 is kept in equilibrium in the form of carbonic acid. This equilibrium may be disturbed by the change in pH; resulting in a difficulty to breathe.
Other effects such as fatigue, headaches and nausea may also be observed as the blood circulates throughout your body and its functions will be impaired by the changed pH.
