Answer: a specific gender
Explanation:
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Answer:
Complementary base pairing
Explanation:
DNA probes are the single stranded stretches of nucleotides that are complementary to the original strand. DNA probes are used in various molecular technologies like polymerase chain reaction and DNA finger printing.
DNA probes can only hybridize with the specific complementary base pairs. Hence, complementary base pairing determines the specificity of DNA probe.
Thus, the correct answer is option (D).
<span>When a tuning fork vibrates over an open pipe and the air in the pipe starts to vibrate, the vibrations in the tube are caused by d. resonance. When the tuning fork vibrates near the open end of the cylinder, the sound waves from the fork are sent into the pipe. When one object vibrates, it forces another object to vibrate at the same frequency and this is called resonance</span>
