It indicates that our ancestors had a different build than humans of today.
Answer:
the answer is
Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.Increasing the light intensity increases the rate of photosynthesis, until some other factor a limiting factor becomes in short supply. At very high light intensities,photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature.
Explanation:
Answer:
The answer is W. chloroform-chloroform and acetone-acetone interactions are stronger than chloroform-acetone interactions. This is because the bond between acetone-acetone is a dipole-dipole interactions and chloroform-chloroform dipole-dipole compared to the weaker hydrogen-bonding between acetone-chloroform.
It turns out that this hydrogen-bonding happens to be stronger the original dipole-dipole forces, so this shows NEGATIVE DEVIATION from Raoult's law.
Answer:Toothed whales do not make the long, low-frequency sounds known as the whale song. Instead they produce rapid bursts of high-frequency clicks and whistles. Single clicks are generally used for echolocation whereas collections of clicks and whistles are used for communication.
Answer: D. All living cells come from other living cells.
Explanation:
A is incorrect because organisms like bacteria and amoebas are unicellular, or have 1 cell.
B is incorrect because cells are specialized: nerve cells and muscle cells do not share the same function.
C is incorrect because inanimate objects are not alive and do not have cells.
D is correct because cells reproduce by mitosis, creating copies of themselves.
