The correct answer for this question would be the second option. The one who invented he polymerase chain reaction (PCR) that allowed scientists to enlarge and study genetic material is Kary Mullis. PCR is <span> a technique that amplifies specific DNA sequences from very small amounts of </span>genetic material<span>. Mullis invented this while he is at Cetus. </span>
B. semicircular canals.
these are found in our ear and works by movement of a liquid and some sensory hair cells inside ear. when ever head moves in any direction sensory hair cells feels a movement of liquid and sends a signal to brain.

Answer: It is exchanging genetic material between two paired chromosomes
Explanation:
Animal fats and hydrogenated vegetable margarine contain saturated triglycerides. Saturated triglycerides are those that are made of saturated fatty acids. These saturated fatty acids are capable of forming atheroma (/plaques) along arterial walls, causing atherosclerosis or arteriosclerosis. These could both result in coronary thrombosis (blocking of a coronary artery by a clot of blood), and hence a myocardial infarction (heart attack).
Microorganisms can be defined as the organisms which are seen with the aid of microscope. This category includes the bacteria, algae, fungi, protozoa and viruses. These microorganisms play an important role in the decomposition of the biological materials. The nutrients are also recycled by these microorganisms. the microorganisms bound in a soil serve this purpose. Moreover, the microorganisms, such as algae carry out the process of photosynthesis and make their own food.
Some of the microorganisms have complex relationships with different animals and plants both, which help in their survival.
Hence, the right options will be "carry out photosynthesis, decomposition, and nutrient recycling'.
