Answer:
Bio diversity is portamt of the survival of nature. because the various diversity make many differences around us. Look between the rain forest and desert. forest has big diversity but desert hasn't. We breath in every second Co2 export and get the O2. but how they made? they made from the tree.Trees are always photosynthetic and the animals help to there to reproduction cycle. Theta the important of diversity. We all are depend on the nature and diversity.
Nonsense mutation: a sense codon changes into a chain-terminating codon.
Missense mutation: a single nucleotide changes the codon and the corresponding amino acid
Silent mutation: A change in that does not result in a change of amino acids (ex: AAA and AAG both code for lysine)
Answer:
The correct answer is B. Isotopes of an element differ in the number of neutrons.
Explanation:
Isotopes are atoms of the same chemical element, and therefore with the same number of protons, in which the number of neutrons in the atom core differs. According to current models, an atom consists of an atomic nucleus surrounded by a cloud of electrons. The core consists of a number of protons and a number of neutrons. The number of protons determines the atomic number of the element and also the chemical properties. The number of neutrons determines, among other things, the stability of the nucleus and, together with the number of protons, the atomic mass. Two atoms with the same number of protons but a different number of neutrons are called two isotopes of the same element.
"Cell membrane" Outermost layer surrounding the cytoplasm.
The answer is "Speciation".
When a population of organisms gives rise to new more species and this new species cannot effectively breed with one another, the term for the process is called Speciation. It refers to the evolutionary process in which the reproductively isolated populations of species evolve to become distinct species.
