Activation energy is the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
for example , striking a match on the side of a matchbox provides the activation energy, in the form of heat produced by friction.
Answer:
The cell membrane separates the external and internal environment of the cell. The cell membrane is composed of bilayer lipids, proteins and small amount of carbohydrates.
The lipid part is soluble in hydrophobic environment or with the hydrophobic part of other phospholipids because like molecules dissolve in like molecules. The hydrophobic part is non polar and hydrophilic parts is able to dissolve in polar area due to the interaction of same molecules with each other.
Hey there! Cellular membrane and cell wall is your answer.
No.Tissue is a group of cells.If the organisms is single called,it can't form a group to make tissues.
Annual range is the difference of the mean temperature between the hottest and the coldest month.
<span>Cullowhee, NC,
Hottest month:
July - Ave. High: 85 </span>°F ; Ave. Low - 62 °F . Mean = (85+62)/2 = 73.5 °F<span>
Coldest month:
January - Ave. High: 48 </span>°F ; Ave. Low - 24 °F. Mean = (48+24)/2 = 36 °F
Annual Temperature range = 73.5 - 36 = 37.5 °F

</span><span>Hottest Month:
July: Ave High: 90 </span>°F ; Ave. Low: 66 °F; Mean = (90 + 66) / 2 = 78 °F<span>
Coldest Month:

Los Angeles, CA - lowest annual temperature range</span>
Hottest Month:
August: Ave High: 79 °F ; Ave. Low: 62 °F ; Mean = (79 + 62) / 2 = 70.5 °F
Coldest Month:
December-March: Ave High: 67 °F ; Ave. Low: 51 °F ; Mean = (67 + 51) / 2= 59 °F
Annual Temperature range = 70.5 - 59 = 11.5 °F
