two hydrogen bonds are formed between adenine and thymine
Similarities: Natural Selection and Artificial Selection both result in the alteration of the gene pool. It can also change phenotypes of different species'.
Differences: Artificial Selection is when a specific trait is not wanted, and so it is not bred.
For example, humans did not like how yellow peas looked. They liked the healthy looking green better. So, they killed the yellow peas, and bred the green peas with other green pea plants, and right now it is almost completely out of our gene pool.
Natural Selection is when something naturally occurs, such as a natural disaster, famine, plague, invasive species introduction.
For example, if 10 camels lived in a desert, but one of them didn't have as good of a metabolism and stayed full longer, then that one would survive, while the others might not.
The answer is B: 'the smoke that results is toxic'. An example is the burning of domestic garbage, which remains a common practise, particularly in developing countries. This practice can release g<span>reenhouse gases like carbon dioxide and also tiny particles and toxic chemicals that can harm human lungs.</span>
Answer:
B. The mRNA produced has a different base sequence
Explanation:
Transcription is the process in which mRNA is transcribed from DNA, which is then translated into a protein.
An error made during transcription does not alter the sequence of the DNA. Therefore, the gene itself is not altered and the error is not passed on to the next generation.
Carbohydrates are never produced by transcription and translation, which produce polypeptide chains which from mature proteins.
