Add the protons and neutrons to find atomic mass 5+4=9. the atomic mass is 9
<span>The basic building blocks of a cell membrane are phospholipids. Phospholipids contain a hydrophobic (insoluble in water) end made up of two fatty acid chains of nonpolar molecules such as carbons and hydrogens. The other end is hydrophobic (soluble in water) and contains polar phosphate molecules. These phospholipids are arranged in a bilayer with their hydrophilic end group exposed to water on each side of the membrane and the hydrophobic nonpolar molecules protected inside the double layer. </span>
Answer:
6.) larger diameter of stomatal pores
A) Increased transpiration pull
1.) thicker film of water on surface of mesophyll cells
2.) higher relative humidity in air around leaf
B) decreases transpiration pull
3.) less curvature of water surface on mesophyll cell walls
4.) lower rate of water evaporation from surface of mesophyll cells.
5.) larger air space in leaf interior
C) has no effect on transpirational pull.
Explanation:
- Transpiration primarily occurs through stomatal openings in the leaves. Increasing the diameter or size of these opening would ultimately increase the amount of water escaping from them and therefore, increase the transpiration rate.
- Higher humidity in the air entails the presence of greater number of water vapours in the atmosphere. Since osmotic pressure plays a major role in transpiration, therefore, this decreases the rate of transpiration.
Answer:
Sedimentary rocks are classified based on how they form and on the size of the sediments, if they are clastic. Clastic sedimentary rocks are formed from rock fragments, or clasts; chemical sedimentary rocks precipitate from fluids; and biochemical sedimentary rocks form as precipitation from living organisms.
Explanation:
