Darwin went to the continents of Africa and South America, wherein both of them have a tropical grassland/Savanna biome. The grasslands in these continents gave him a chance to notice that species do vary globally. He observed the similarities between the different large, flightless birds species–rheas, ostriches, and emu.
To start with, let's compute the volume using this formula:Volume = length x width x height = 9in x 4in x 9in = 144 in
For the second item, use the same formula to get the volume:Volume = length x width x height = 1.89 in x 4in x 9in = 68.04 in
Just take note to indicate your in with an exponent of 3. I just can't type it here so do it when you do your assignment.
Answer:
The correct answer is B.. The enzyme is like a lock, and the substrate is like a key.
Enzymes are bioctalyst which accelerate the bio-chemical reactions taking place inside the living organisms.
Enzymes have specific region in their structure for the binding of their substrate which is called as active site. The shape of the active site of the enzyme complements the shape of the substrate.
The shape and amino acid residues of the active site provide the specificity to the enzyme for its substrate.
It can be easily explained with the help of lock and key model in which a substrate (key) perfectly docks in the active site (key hole) of the enzyme (the lock).
Their digestive systems cannot digest solid foods until that age
Condensation is the formation of clouds.
