The ones that survive the best with their traits in their natural environment go through natural selection for their best traits.
Artificial selection is the intentional reproduction of individuals in a population that have desirable traits. In organisms that reproduce sexually, two adults that possess a desired trait — such as two parent plants that are tall — are bred together.
2) D. behavioral isolation
3) C. Artificial selection
Hope this helped
C. better meat
Farmers always are looking to better their stock to possibly increase milk production or increase the meat quality.
D testing on animals has produced several lifesaving vaccines
this would show that despite putting the animal at risk, thousands of lives are saved through its resources.
it is a
Animals that produce human medicines could be cloned.
the answer is a:)
i just did it & i was righ! good luck!!
The correct option is A) Animals that produce human medicines could be cloned.
Dolly is known to be the fist organism which was cloned by nuclear transfer. Before this, organs, tissues etc had been clone but Dolly was the first organism to be cloned.
The successful cloning of Dolly provided scientists with the hope that organisms that were useful to humans could be cloned.
By cloning, we can produce more of organisms with the desired characteristics such as organisms producing a better source of medicine, meat, milk eggs etc.
yeah its C.artifical selection
mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are important factors here. as a cell increases in size, its surface area and volume increase as well. we call that the surface area to volume ratio (sa: vol). but the catch is that volume increases at a greater rate than surface area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow! check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
