Answer:
The features of prokaryotes include circular DNA molecules and small ribosomes.
Explanation:
Prokaryotes are organisms having only one cell (unicellular). In their cells, an organized nucleus is absent along with other membrane-bound organelles. Examples include bacteria and archaea. The prokaryotic cell mainly consists of the plasma membrane, cytoplasm, DNA and ribosomes. Some prokaryotes have special structures such as flagella, pili, fimbriae, etc. Flagella help in the locomotion and pili or fimbriae are used for the attachment to host cells and other surfaces.
Their cells contain large quantities of genetic material (DNA and RNA). A single, large circular strand of DNA is found in the central part of the cell (nucleoid) and contains most of the genes. The ribosomes found in prokaryotes are smaller in size. A large number of ribosomes are present inside a prokaryotic cell. The shape and composition of ribosomes are slightly different than those in eukaryotic cells.
Answer: The correct answer for the fill in the blank is A) Found near coasts.
Chaparral biomes are found in small regions of almost every continent. This generally includes areas near the coast like the coastal areas of the Mediterranean. They have quite hot and dry cimatic conditions.
The different types of terrains in these biomes are slopes of mountains, rocky hills etc. The weather conditions change constantly in these biomes. Therefore, plants and animals found in these biomes adapt quickly to the changing environmental conditions.
Answer:
San Francisco has a history of earthquakes, while New Orleans has never had one. Because of risk assessment, buildings would be built much more sturdy in San Francisco vs New Orleans. New Orleans is surrounded by water and marsh and the area covered with loose sediment, which would exaggerate the ground movement. Both are densely populated but getting out of New Orleans is difficult (ex-Hurricane Katrina)
Explanation:
Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. Imagine what the world would look like! More importantly, decomposers make vital nutrients available to an ecosystem's primary producers—usually plants and algae.
The promise of jobs and prosperity, among other factors, pulls people to cities. Half of the global population already lives in cities, and by 2050 two-thirds of the world's people are expected to live in urban areas. But in cities two of the most pressing problems facing the world today also come together: poverty and environmental degradation.
