Answer:
Hi there the answer to this is A Directional Selection
Explanation:
Directional Selection is considered a 'positive' selection in which favored phenotypes is favored over other phenotypes causing the allele frequency to shift over time. This deals with the height from short to tall. Giraffes are a great example of directional selection.
Hope this was correct :)
Answer:
B.
Explanation:
Yes, Tt and tt have the same geneotype.
Two geneotypes can result in the same phenotype.
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'.
Essential services, such as water purification, nutrient cycling, and plant pollination are all examples of earth's Ecosystem services.
The ecosystem is defined as the interaction between the biological communities with its physical environment. The services provided by the ecosystem are termed as ecosystem services. The ecosystem with the help of its different components performs water filtration, recycling of the nutrients, pollination, seed dispersal etc. These all services provided by the ecosystem comes under the category of ecosystem services.
