What is selective breeding?
None of the below
When you breed two animals together because of their desirable traits to create an offspring with many desirable traits, u do this for many generations
When you breed together two different animals to create a hybrid animal and then sell it for lots of money.
All of the above
What is natural selection?
There is no such thing as natural selection
Natural selection is when the variation of an animal helps it survive longer and reproduce. When it reproduces, it creates another animal that can survive very long. The animals who do not have these variations do not survive.
Natural selection is when humans breed animals to create more animals with desirable traits. For example, if someone wants a chicken that makes very large eggs, they could breed two chickens that do that.
Natural selection is when the animal species that do not survive for long die off completely extinct.
True or false: Individuals that have variations that best adapt them to their environments are most likely to survive and reproduce
(a)
What causes a species bacteria to become resistant to antibiotics?
Variation
Natural selection
Genetics
Adaptation
Why did the pepper moths in England turn brown from pale in 1900?
Because the darker ones were more attractive to moths, so they reproduced more
Because the white ones couldn't camouflage on people's clothes
Because of the pollution during the industrial revolution. The pollution cause the pale lichens on trees to die of and turned the bark brown. The pale moths could not hid from predators on the dark bark.
There is no reason for that to happen.

(a)
Who proposed the theory of natural selection?
Isaac Newton
Neil Armstrong
Albert Eintstein
Charles Darwin
What did the theory of natural selection state?
There is still no such thing as natural selection.
applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature
the individuals that are nest adapted to their environment are the ones that are most likely to pass on their features to the next generation
Gravity is arbitrary and that affects the natural selection of people for certain occupations in which their is realiance for the whole society to function.
(a) is the chemical from which chromosomes are made.
(a) is the part of a cell in which chromosomes are found.
(a) is the part of a chromosome that determines one particular characteristic of an organism.
(a) means that passing on of genes from parents to their offspring.
(a) means the differences between organisms belonging to the same species.
