The artificial selection is a procedure of selectively breeding certain species of plants and animals in order to develop certain desirable traits. Artificial selection helps the humans to get the plants or livestock that are the most useful for them. Among the given options, the choosing of the sheep giving the most wool, mating of the goats producing more milk, and mating of the ducks to produce large eggs are all examples of the deliberate artificial selection.
But the using of the fishing nets that are catching only the large crabs is an example of indirect artificial selection as it leads to the increased population of small crabs.
Hence, the correct answer is 'option d'.
Hey,
I believe this answer is A: The desert plants are likely to be better at retaining water.
Which they do, and they have to cause water is very scarce in the desert unlike the rain forest.
Desert plants likely to be larger is not proven and most plants can vary in size.
Narrower stems may have something to do with it but that goes back to they have to hold more water so this is incorrect.
Brighter flowers doesn't have anything to do with water consumption within a plant so this is incorrect as well.
Hope this helps!
Brainliest is always appreciated if you feel its deserved.
