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'.
Answer:
Durring isolation, one may feel lonely, afraid, unloved, and unimportant.
Answer:
GACCTG (the fourth option)
Explanation:
To find the correct complementary strand, we need to know this simple rule:
T always pairs with A and C always pairs with G.
So whatever letter you have in the DNA strand, the complementary strand will have the complement to it. In this case, we have CTGGAC. The complement of C is G, for T it is A, and so on. Therefore, the correct complementary strand is GACCTG (the fourth option).

Answer:
Autotrophs, but not heterotrophs, can nourish themselves beginning with and other nutrients that are inorganic.
Explanation:
Unlike heterotrophs, autotrophs such as green plants, are able to synthesize their food (in form of sugar molecules) starting with inorganic molecules like atmospheric carbon dioxide, water in the presence of sunlight.
This is commonly known as photosynthesis. The equation is shown below
6CO2 + 6H2O --> C6H12O6 + 6O2 + Energy
