Answer: Prokaryotic cells do not have a nucleus. Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment
Explanation:
The best answer to choose would be — “Weak winds that blow for short periods of time with a short fetch.”
Few factors determinate size of surfing waves:
1The weaker the wind speed, the shorter the wave.
The shorter amount of time that the wind blows, the shorter the wave.
Concluding my statement, and in opposition to the answer, it is the stronger winds along with a long period of time those winds with a long fetch that will be able to make the biggest waves.
Answer:
Within the geological structure of Cayuga Lake Basin there is a diversity of limestone sources, which would make it possible for the lake to be a good location for the construction of a cement-making plant.
Explanation:
Cayuga Lake, part of the so-called Finger Lakes, located in New York, has an extension of about 40 miles. This lake is of great economic and ecological importance, because it allows fishing and recreation activities, besides being a place of passage for migratory birds.
The Skaneateles, Onandaga, Marcellus, Manilius, Moscow and Tully formations are an important source of limestone of variable quality, from which lime can be obtained for the manufacture of cement.
Although the presence of limestone would be ideal for building a cement-making plant, a project of this size should consider the environmental impact it could have.

Answer;
-The bacterium would exhibit positive chemotaxis.
Explanation;
-Chemotaxis is the movement of cells or organisms in response to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.
Flavonoids play a crucial role as signal molecules in promoting the formation of nodules by symbiotic bacteria commonly known as rhizobia. The roots of leguminous plants use positive chemotaxis to attract rhizobia. Flavonoids are the chemicals associated with attraction of Rhizobium bacteria.
