Since it’s in the ratio of 1:2:1 the genotype will be Rr and Rr.
CO2 + H2O = O2 m + C6H12O6 photosynthesis
C6H12Og + O2 = CO2 + H2O + ATP respiration
Answer:
The options are :
The spaces get wider because the concrete sections shrink.
The spaces stay the same because the concrete sections does not shrink or expand.
The spaces get narrower because the concrete sections expand.
Some spaces get wider, some spaces get narrower, and some spaces stay the same because each concrete section behaves differently on a hot summer day.
The answer is
Some spaces get wider, some spaces get narrower, and some spaces stay the same because each concrete section behaves differently on a hot summer day.
Concrete surfaces react with a change in temperature by either shrinking or expanding depending on the temperature difference.
When there is an increase in temperature it expands a bit and shrinks a bit too when the temperature is decreased.
