Answer:
The correct answer would be - crust, mantle, outermost and innermost layer.
Explanation:
It is not possible to travel through all of the layers of Earth, however, Hypothetically, if an individual takes a journey of traveling to the core of the Earth, he needs to go through total five total layers, including the "center of the Earth" as described in Jules Verne's novel.
The crust is the first and outermost layer of the earth from the top of the earth's surface. It is the layer we and all geographical areas such as caves present. The second layer is the mantle that can be distinguished in the upper mantle is the primary mantle itself. After the mantle person would enter the outer core and then the final layer is the inner core.
Cephalization is the differentiation of end part of the body into a head in which nerve tissue is concentrated. Sponges have a very loose nervous system and their cells work individually, not controlled by a nervous system. Since they have no defined head as a consequence of concentrated nervous system, the sponges could not have cephalization either.
Answer:
Polyploidy
Explanation:
Polyploidy can be defined as a rapid method of speciation that has been important in the history of flowering plants.
In plants, it involves the possession of two complete sets of chromosomes and it leads to the origin of new species.
Hence, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).
Answer:
Explanation:
The DNA double helix acts as a template for its own duplication. Because the nucleotide A will successfully pair only with T, and G only with C, each strand of DNA can serve as a template to specify the sequence of nucleotides in its complementary strand (more.
