How do fossils provide evidence that suggest that evolution has occurred ASAP

Biology

QveST [7]4 years ago
5 0
When looking at fossils from a specific animal, with further detail it can be determined if there are any animals that are living now that could possibly be related to each other. For example it can be determined that a elephant was related to the once known mammoths simply because of how similar there bone structure was and the way they looked physically. If elephants were once mammoths then it could be suggested that after a long period of time they evolved to live in warm climate which made them lose their fur and how they became smaller in size.

Alleles for other genetic diseases also provide protection against malaria when only one copy of the allele is present. In what
Ugo [173]

Answer:

The correct answer will be- red blood cells (RBC)

Explanation:

Malaria has proved endemic to the human species as it has killed the humans in large numbers and it has acted as one of the strongest selective force.

The malaria disease has caused the mutation in the genes in the red blood cells which carries the oxygen to different organs of the body. The mutation in the genes causes the circular shape of red blood cell to sickle-shaped cells which carry less oxygen to the organs.

The change in the shape of red blood cell provides resistance against malaria disease but it becomes a problem where malaria is not a problem.

Thus, red blood cells (RBC) is the correct answer.

how does the second law of thermodynamics help explain the diffusion of a substance across a membrane?
Damm [24]

The second law is the trend toward randomization, or increasing entropy.  

Second law allows for diffusion because diffusion is an increase in entropy .Diffusion is the process of movement of molecule down the concentration gradient until they doesn't exist . This movement represents an increase in the entropy.

Second Law of Thermodynamics state that molecules will spontaneously move towards an area of lower concentration, from an area of higher concentration. Molecule are capable to travel across cell membranes known as lipophilic molecules as they dissolve in the lipid bilayer. Movement represents an increase in the entropy or disorder in the system .
