ans 11) The art productions and architectural designs represent the following:
(*note*-pls hep yourself in expanding the points)
=> the beliefs of the ancient Egyptians.
=> the culture.(the way they used to live)
Answer:
land. land is heated and cooled faster than the sea? why you may ask?
Explanation:
water reflects most solar radiation that reaches its surface back to the atmosphere. since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. thus, land surfaces warm more quickly than water.
hope that helped you! <3 ;)
Ans.
The mutation that results in a mouse with less light fur as compare to other mice of same population, makes it easier for the mice to blend into their surrounding environment. According to law of natural selection, if a genetic mutation is beneficial for a population, the mutated organism survives to reproduce and that mutation gets transferred on to its offspring.
Thus, the correct answer is 'option). the mouse with the genetic mutation will survive and reproduce, and the trait (for fur) will spread over future generations.'
The correct answer is option (C) transposons or jumping genes.
Barbara McClintock was an american cytogeneticist. In 1940s, she discovered the phenomenon of transposition brought about by the mobile genetic elements or jumping genes or the transposable elements. These jumping genes refers to a sequence of DNA which can change its position in the genome or the genetic constitution of an organism. She discovered these jumping genes in the Maize for the first time and received the nobel prize in 1983.
Jumping genes form a major portion of the eukaryotic genome. They are often responsible for mutations and associated with the duplication of the genetic material. They also cause the structural changes in the chromosomes like inversion, deletion and translocation which are called the chromosomal aberrations.
