The number of chromosomes in a female
scorpion’s egg cells have half as many chromosomes as compared in her body
cells. Chromosome is a single long molecule of DNA wound around proteins called
histones. It is
made up of DNA wrapped around proteins.
Answer:
- They are made of denser objects, which can condense at relatively high temperatures;
- They are made of heavier elements, which have a stronger gravitational attraction to the Sun;
The process where a specie develops and evolves into new many species is termed as speciation. Macroevolution explores the mechanism of speciation where organisms across biological populations evolve as distinct population.
There are many causes to speciation, a) geographic isolation, b) gene flow reduction, and c) reproductive isolation.
