The difference between these three types of rock is in their formation process:
• Igneous rocks are formed by thesolidification of melted rocksm(agma) inside the Earth.
,
• Metamorphic rocks are formed from the other types of rock that suffer changes due to different processes,for examples caused by high preasures or heat.
,
• Sedimentary rocks are formed by the accumulation
Answer: D(nucleoid region)
Explanation:
In the diagram below the irregular shaped, supercoiled region, without a membrane, labelled D, surrounded by the cytoplasm of the cell is the nucleiod region that contains the main DNA in bacterial.
The nucleoid region in the prokaryotic cell contains the main DNA material. The nucleoid which means nucleus-like contains the main genetic material in prokaryotic cell, some satellite DNA are found in plasmid is other parts of the cell. Unlike the nucleus of eukaryotic cells the nucleiod lacks a cell membrane. The nucleiod has an irregular shape, and has a circular chromosome.
Answer:
Biogeographic isolation is the separation of organisms of a species through geographical or biological forces.
Explanation:
Chloroplast, the food producer organelle of plants and some other organisms (but not animals), can be found in virtually all plants. They house Chlorophyll, a pigment which plays a key role in photosynthesis, which turns sunlight into energy for plants. Chloroplasts can be found in the leaves of trees, the leaves of vegetables, and in algae.
