Cladograms is a branching which bears a lot in common with the idea of family trees. In a cladogram what occurs at a node is a "splitting event". <span>At each </span>node<span> a splitting event </span>occurs which represents the cumulative change that happens in population over time.
Meiosis is two rounds of genetic seperation while, mitosis only has one. Both of these process of cell division and replicating is associated with cytokinesis.<span>The end result of both are daughter cells produced from a parent cell</span>
This observation can be explained by the theory of endosymbiosis. From what scientists have discovered, it can be explained that the double membrane of both chloroplast and mitochondria are as a result of them been subjected to phagocytosis but they were not digested. Their DNA suggest that they were once free living prokaryotes. This agree with the endosymbiosis theory which states that eukaryotic cell organelles developed from prokaryotic cells.
Out of the following given choices;
A Bowman's capsules
B afferent and efferent arterioles
C nephrons
D collecting duct
E glomeruli
The answer is D. Also known as vasopressin (a stress hormone)
acts on the receptors of the collecting ducts of the nephron during water
stress to increase water reabsorption. The hormone stimulates water reabsorption by stimulating insertion of
"water channels" or aquaporins into the membranes of kidney tubules.
Answer:
The correct answer would be "The percentage of dark brown sea lions will increase, and the percentage of light brown sea lions will decrease".
Natural selection refers to the natural phenomenon by which organisms which are better adapted to the changing environment tend to survive and reproduce more as compared to the organisms which are less adapted.
As aquatic environment make dark brown sea lions more reproductively successful thus, the offspring of dark brown sea lions would have better chances to reach the reproductive age.
Hence, with the percentage of dark brown sea lions would increase and that of light brown sea lions would decrease.
