Answer:
D
Explanation:
temperature can change the arrangement of the protein molecules which is called denaturation. thus changing the shape for the protein receptor.
Answer:
Because, Air (or any gas) takes up space in water, just like solids. Air (or any gas) is less dense than water, so gas bubbles float to the top of water.
DNA or deoxyribonucleic acid is macromolecule composed of nucleotides (nitrogen nucleobase, deoxyribose sugar and phosphate group) which carries genetic information (instructions). Instructions within DNA are for development, growth, reproduction and many other functional roles of an organism.
All of the cells within an organism contain the same genome (full set of DNA-chromosomes). When cells begin the process of differentiation (cells become specified) their genome stays the same, but the gene expression is different (different genes are on or off).
Answer:
B
Explanation:
a plant living in a dry region means it will need to have less stomata on the upper surface of the leaf than the bottom to save as much water as possible since a more drier region lacks water, so look for a plant that has the least number of stomata on the upper surface - B
it has no stomata on the upper surface of the leaf which means less water loss through the stomata via transpiration
