I think the first statement is true; while the second statement is false. It is true that drinking sea water would cause a rise in the osmotic pressure of the extracellular fluid because sea water will be hypertonic (salty water) to the extracellular fluid therefore water will move from the extracellular fluid osmotically creating an a rise in osmotic pressure. The whole effect won't make water leave the blood capillaries.
Answer:
C
Explanation:
When researching on the lineage of 2 animals from a common ancestor, one can deduce it accurately from DNA samples and various bodily characteristics from the body of the 2 animals in comparison to the common ancestor.
A) Strands of DNA allows for scientist to deduce the percentage similarity between 2 animals. The more similar means that the closer the relatedness is between 2 species.
B) Bones and muscle structure gives one a rough gauge on similarity of both organisms. E.g. Compare human bone, muscle to chimpanzee bone muscle.
C) Comparison of food items is the worst methods as different species may feed on different types of food due to natural selection. E.g. Finch bird example on the galapegos island or sth.
D) growth of embryos of similar animals would have similar developmental stages and changes that is quite distinct to each species, allowing one to deduce the closeness of the 2 animals to a common ancestor.
Answer:
Explanation:
Most organisms are adapted to live within a particular range of temperatures and will not survive at temperatures too far above or below their range. Precipitation limits the organisms that can be found in a biome because all organisms need water, and the bigger the animal, the more water it needs.
