How does natural selection affect variation?
Variation naturally occurs in populations as new traits arise from random mutations. However, through natural selection only those traits that are beneficial to the organism are passed on to the next generation. Any harmful mutations are naturally weeded out.
What causes variation in human beings?
the variations in genes, genes of sexually reproducing organisms will vary due to crossing-over of genes, mutations, and adaptations. In asexually reproducing organisms genes will vary through adaptations and mutations.
Are punnett squares used to show the results of sexual or asexual reproduction?
Sexually because of the genetic variation between parents. Asexuals can't really use punnett squares because only one parent is there and no variation really occurs except through mutations.
Does the graph of an inverse variation pass through the origin?
Inverse variation does not pass through the origin, however direct variation always passes through the origin.
How does slow change over time occur genetically?
Through mutations in DNA, and natural selection of advantageous mutations.
How are mutations passed down from parent to offspring?
Mutations can be passed from parent to offspring only by mutations found in genes. These genetic mutations can be hereditary. Chromosomal mutations only occur in one person and cannot be passed on to the offspring.
Why do features of gulls enable them to be classifi ed in the vertebrate group?
Gulls are classified as vertebrates because they have a backbone. more specifically in the bird classification because they take oxygen through their lungs, they maintain their own temperature (homeotherm). They reproduce through internal variation, so they lay eggs (oviparous).
Some vertebrates can go through nymph and pupa forms?
No
How does the constant of variation affects the appearance of the graph of a direct variation function?
The formula direct variation is xk=y, where k is the constant of variation.Direct variation functions always pass through the origin. Direct variation functions are linear functions (goes in a straight line), except that they pass through the origin. Regular linear functions don't pass through the origin. That is the only difference.
What is the constant of variation k of the direct variation y kx through (3 2)?
It is 2/3.
What is the relationship between natural selection and adaptation?
Adaptation is a future generation, and a natural selection is when the Natural Resources select the generation continued. Natural selection is the evolutionary driver of adaptive change. All organisms born are variations and the variation that survives and reproduces better than its conspecifics will have more progeny with the selfsame adaptation that helped the organism to survive and reproduce. Thus, through mutation leading to variation and mutations leading to improvements on that variation natural selection chooses and shapes the organism to be well adapted to its immediate environment.
What is the class of a vertebrates that breathe through their lungs and their skin?
how do birds breathe
