I believe the answer would be A.
The flow is larynx, trachea, bronchi, bronchioles, alveoli
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.
This is because the traits like height, are influenced by environmental conditions around the individual. For example, there are two children born to same mother. But one is given best facilities, nutrition and care, whereas other one is brought up by a poor family, which hardly get good food to eat. His condition is much worse than the first case. In such a situation, the former child will grow up healthy and fit, and will have more height than the later one. Although, both got genes from same parent, but the environmental conditions influenced the expression of those genes differently.
I believe the answer is heart, liver, pituitary gland, kidneys, and skin! hope this helped :)
Put the steps of the carbon cycle in order using Step 1 as your starting point. Step 1: Carbon dioxide is taken in by plants during photosynthesis.
The cycle repeats when the carbon stored in the atmosphere as carbon dioxide gas is taken in. step four
The animal releases the carbon dioxide back into the atmosphere during respiration. step three
The animal eats a plant and uses its carbohydrates for energy. step two
