Octopus and squid have chemoreceptors on their tentacles. The correct option is the third option.
Prostatis, or inflammation of the prostate (elevated PSA), likely due to bacterial infection, hence the elevated white blood cell count. This is sometimes also referred to as benign prostatic hypertrophy (BPH).
Answer:
Volume
Explanation:
The boiling point and density of water never changes, no matter how much you add
So the answer CAN'T be Boiling point or Density
Electrical Conductivity changes <em>only when the number of ions in a solution changes</em>
So it CAN'T be Electrical Conductivity
It has to be VOLUME because volume is the only physical property that changes when you add or take away liquid from a liquidous mixture
According to Darwin's Theory of Natural Selection, each generation produces more individuals than the ecosystem can sustain. However, not all individuals are identical and phenotypical variation exists.
Due to this variation, some antelopes are better at escaping lions, perhaps due to speed and/or stamina. Thus, the individuals that are slower and thus less fit will be killed and eliminated from the herd. The antelopes with heritable traits that makes them better suited to the environment, will escape and thus, survive and reproduce.
In Darwin's Theory predation is an evolutionary force.
