You have to write a letter to a friend about what u learned in Science class. Here is a example
Dear Jamie, I want to tell u about some interesting things.I learned in Science class today. About
~ Cloning - the process of producing similar populations of genetically identical individuals . PUT in own words.
*Genetic determinism of sexes
*Two types are known.
I. Drosophila met at mammals , insects and some plants.
a) Chromosomes have notation:
Masculine ⇒ xy
Feminine⇒xx
II. Abraxas met at amphibians,reptiles,birds and fish.
a) Chromosomes have notation:
Masculine⇒xx
Feminine⇒xy
decline in air, land and water pollution; no one to ensure proper disposal of toxic wastes; decreased destruction of habitats; increase in species extinction
The answer to this is false because some nuclear radiation is slow. <span />
The genetic variation between humans and orangutans is the greatest is the right option.
Explanation:
A phylogenetic tree is illustration which shows evolutionary relationship between different species. This concept is based on Darwin's descent with modification.
Human and orangutan are 97% similar in their DNA sequences.
The difference in DNA bases shows large genetic variations in both the species.
The species are organized on the basis of traits that are changed over time as compared to their ancestors as they evolve.
Less related species will have more differences in their DNA sequence.
The phylogenetic tree formed indicates that orangutan and human are less related to each other than other species.
