Which membrane give eukaryotes an advantage over prokaryotes in protecting their genetic material from damaging chemical changes?
The nuclear membrane, found in eukaryotes, separates the genetic material from the rest of the cell, providing better protection from damaging chemical changes compared to prokaryotes that lack this membrane-bound nucleus. This physical barrier helps prevent harmful substances from reaching the DNA, decreasing the risk of mutations or damage.
How are variations and mutations linked?
Variations are differences in traits among individuals, while mutations are changes in the DNA sequence that can lead to variations. Mutations are one of the mechanisms that create variations in a population, which can then be passed on to future generations. In this way, mutations contribute to genetic diversity and the potential for adaptation in a population.
What are three main ways that variations in genotype arise in population?
Variations occur due to mutations. There are three factors of mutations which impact the formation of new genotypes. 1) Point Mutations - Very small impact mutation which still might enhance the protection against environment and reproduction. 2) Mutations that alter Gene number and sequence - has major role in evolution as it might help to add new functions. 3) Mutation Rates - In animals and plants mostly very slow, however, prokaryotes due to high rate are able to mutate very fast.
How do mutations increase variations?
Mutations are changes in the DNA sequence that can lead to differences in traits. These variations can result in new genetic combinations, increasing diversity within a population. Over time, these mutations can be passed on to future generations, contributing to the overall biodiversity of a species.
What is the relationship between genetic variations and mutations?
Mutations are random changes in DNA; genetic recombinations are new arrangements of genetic material (as a result of sexual reproduction). Together, they are the "fuel" that powers the "evolution machine," the direction of which is determined by natural selection.

What causes variations in numbats?
Mutations in a numbat's DNA.
Can mutations increase the variations in a species' traits?
Yes
What effect can mutations on a virus?
They create genetic variations.

Why are most mutations in eukaryotes recessive?
Most mutations in eukaryotes are recessive because for a mutation to be expressed phenotypically, it typically needs to be present in a homozygous state. In a heterozygous individual, the presence of one normal allele usually masks the effects of the mutated allele, leading to a recessive trait.
Why are mutations and conjugation important for natural selection in prokaryotes?
Becauase they need to adapt to the new environment to enter the bodies
What did Darwin call individuals that express mutations?
Darwin referred to individuals that expressed mutations as variations or variants in his theory of evolution.
