The answer is: B) silkworms.
“While sitting in her garden she deduced the secret of silk by watching the silkworms. She developed the process to remove the thread from the cocoon and set up silk cultivation farms and the weaving of the new cloth.” (Source: http://4kyws.ua.edu/SI_LING_CHI.html)
Answer:
D) The encoded protein contains four repeats of a specific sequence.
Explanation:
The polymerase chain reaction is a technique used to replicate or amplify the amount of DNA sample.
The technique employs running the DNA samples on the gel through which the DNA samples run based on their sizes.
The large-sized DNA fragment runs to a less distance whereas the small-sized DNA run to a large distance.
In the given question, four sizes of DNA bands are formed in the ratio of 1:2:3:4 which shows that the proteins encoded by this DNA have four repeats of a specific sequence of the template strand. This was confirmed when the largest band sample was again used as a sample of PCR and the PCR resulted in the four bands in similar 1:2:3:4.
Thus, Option-D is the correct answer.
Introduction to the outer condition and conceivable cancer-causing agents and, or the fast rate of mitosis that would enable malignancy to spread rapidly.
The skin has body securing capacities, it shields the interior organs from the introduction of the outer condition. It likewise pieces infections and other hurtful substances.
Soaring is a science when birds remain airborne and moving without flapping their wings. They are maintaining thrust and gliding downward but staying aloft
<h3 /><h3>Further explanation</h3>
Soaring birds is where the birds can maintain flight without wing flapping, because they using rising air currents. Many gliding birds are able to lock their extended wings by means of a specialized tendon. Some land birds such as vultures and certain hawks, sustain flight for long periods without flapping their wings.
For example soaring California Condor spreads its primary feathers so that each acts as a small, high-aspect-ratio wing. This reduces turbulence at the wingtips and helping the condor to stay aloft circling slowly in thermals.
Vultures have a low aspect ratio (ratio of length to width of the wing) which generally produce a lot of drag. Vultures overcome the problem of by flying with their primary feathers extended, creating slots between them. Each primary serves as an individual high-aspect-ratio wing. This high-aspect-ratio reducing wingtip turbulence and lowering the stalling speed of the wings. This helps vultures to circle in thermals, maintaining thrust by gliding downward, but staying aloft by sinking at a rate slower than the hot air rising.

Answer:
The correct answer for the fill in the blank is - A sequence of bases on the DNA that codes for a trait.
Gene is described as a segment of DNA ( deoxyribonucleic acid) that codes for a particular protein, which in turn corresponds to a trait/ characteristic of the living organism.
Gene is first transcribed into mRNA ( messenger RNA) through a process called transcription. mRNA is then converted into protein through a process called translation.
The protein thus formed corresponds to a particular trait ( like eye color, hair color).
