Answer:
species rose by allopatric speciation when Isthmus of Panama separated the ancestral species.
Explanation:
- The causes of the morphological and the genetic comparison of the groups of 30 species can be explained by the part of the species that have an allopatric specialization.
- Suggest the mode of the specialization that occurs when the biological population of the same species becomes isolated with each other
- This prevents the interference of the gene flow.
- The isthmus of the Panama is a narrow strip of the lands and contains the countries of the Panama and was formed about 2.8 million years ago.
(1) convection occurs in substances that flow.it can be initiated by uneven heating. (2) in the mantle convection of hot rock creates plumes which move tectonic plates. in the outer core convection causes magnetism. (1) is your first question and (2) is your second. hope this helps! :)
Answer:
True
Explanation:
The process whereby ions such as sodium and potassium are passed across cell membrane in human cells is known as membrane transport system. This process is regulated by a series of mechanism which involves the creation of electrochemical gradients across the plasma membrane of the cells. The membrane transport system is powered by energy in form of ATP. The three major electron transport system in humans are passive transport (diffusion), osmosis and facilitated diffusion.
Answer:
1. kept north and south Korea apart
Explanation:
This armistice signed on July 27, 1953, formally ended the war in Korea. North and South Korea remain separate and occupy almost the same territory they had when the war began. The Korean War, which began on June 25, 1950, when the North Koreans invaded South Korea, officially ended on July 27, 1953.
