When you see butterflies with different wing colors, you should conclude that there's a difference in their protein expression, so there's a mutation somewhere in the genome of the butterfly with the new color.
To answer the first question, if the desired color exists in nature, you should take the specific butterfly's caterpillars and raise them. If the desired <span>butterfly color doesn't exist in nature than you should wait for the mutation to occur (which could take many years) or look for the gene in the butterfly which is responsible for the pigmentation of their wings.

For the second question, mutations in the gene of the coloration of the butterfly's wing could change the color, so what scientist do is to try to provoke different mutations on the caterpillar's gene until they have a butterfly with the desired color.
So everything is about molecular genetics, every difference between species is due to mutations.
The great white shark is about 4.5 meters in length, but some can be as large as 6 meters. They weigh about 2250 kilograms. The top part of their bodies are usually blue-gray in colour. Great white sharks can reach a speed of up to 25 kilometers per hour. They search for food near the surface of the ocean. They stay below deep in the water where they are well hidden.
Hope it helps!

Answer:
<h2>letter A</h2>
Explanation:Whittaker placed bacteria in their own kingdom, Monera, because of fundamental organizational differences between prokaryotic bacterial cells, which lack membrane-enclosed nuclei and organelles , and the eukaryotic cells of other organisms that possess internal membranes. Plantae, Fungi, and Animalia consist of complex, multicellular eukaryotic organisms that differ from each other in details of cell structure and in how they secure and process energy. Protista is a collection of single-celled eukaryotic organisms and simple multicellular forms, some animal-like, some plantlike.
<h2>letter b</h2>
Molecular evidence, particularly from ribosomal ribonucleic acid (RNA), suggests that the five-kingdom scheme is also too simple. Some biologists believe that Protista should be partitioned into three or more kingdoms. Similarly, kingdom Monera contains two very biochemically distinct groups of prokaryotes: archaebacteria, and eubacteria. A proposed system acknowledges this ancient evolutionary split by creating a higher level of classification, domain, above kingdom. This system distinguishes three domains: Archaea, Eubacteria, and Eukarya (containing protists, plants, fungi, and animals).
Adenine always pairs with Thymine, and Cytosine always pairs up with Guanine in DNA. When dealing with RNA, however, Uracil replaces Thymine. So in RNA, A pairs with U and C pairs with G. (just a fun fact) :)
Answer: B. The blood is circulated out of the body for cleansing and then returned.
Explanation:
Hemodialysis is a medical therapy in which the patient's blood is taken out with the help of tubes and treated out of the body. The blood is pumped out using the blood compartment. The blood is circulated using a external filter, that is called as dialyzer. The blood get cleansed and impurities are removed and purified blood returned via circuit back to the body. This technique is used to control the blood pressure and balance of important minerals in the body that involves the potassium, sodium and calcium in the blood.
Based on the above information, option. B is the correct option.
