Answer:
b. the use of DNA as the information storage molecule
Explanation:
Prokaryotic cells are the ones that lack the membrane-bound organelles and well-defined nucleus. Eukaryotic cells have the nucleus and other membrane-bound organelles. Most of the prokaryotic cells are smaller in size as compared to eukaryotic cells. Despite these differences, both prokaryotic and eukaryotic cells have DNA as their genetic material. DNA serves to store genetic information in both types of cells.
Answer:
B. Fungicides to treat affected crops and planting rust-resistant varieties
Explanation:
Leaf rust is a disease caused by the fungus <em>Puccinia triticina</em> which affects leaves, stems and grains in wheat and related cereals (i.e., barley and rye). This disease is known to affect crops in moist conditions. Leaf rust disease is spread through fungi spores from infected wheat plants to healthy plants. Recently, leaf rust-resistant varieties have been developed by crop improvement programs aimed at introducing leaf rust-resistant (lr) genes involved in resistance against this important crop disease. Moreover, there are different types of fungicides (e.g., Prothioconazole and Tebuconazole) used for chemical control of this disease.
Answer: The blood vessels surrounding your stomach and intestines constrict and the digestive muscles contract. It's that drop in blood flow that makes you feel like winged insects are fluttering around in your stomach.
Explanation:
<span>PCR is a relatively simple process because it only requires three cycles to produce enough of the desired DNA.
