Natural casts
Natural casts are fossils that consistof minerals that are filled in an open mold of an organism. This type of castsis made when minerals are deposited in the mold. Casts can also be syntheticallyproduced when the molds are filled with synthetic material such as latex.
b. reservoir
c. stream
d. pond
The one that is a man-made aquatic habitat is a reservoir. The correct option is b.
Technically speaking, “reservoir” usually refers to an expanded lake behind a dam. Such a dam could be a man-made structure created to hold freshwater, or it could be a natural development. Reservoirs are man-made bodies.
Lake is any big body of still water or gently moving water that fills a sizable inland basin. There are no well-established definitions that clearly separate lakes, ponds, marshes, or even rivers, etc.
A body of water moving on the earth, such as a river or creek. A tiny body of still water that has been created either naturally or artificially. They are all-natural water bodies.
Therefore, the correct option is b. reservoir.

Answer:
Option A- It allows for genetic variation among organisms.
Meiosis is important for organisms since it allows for genetic variation among organisms.
Further Explanation:
Mitosis and meiosis are two different types of cell division. Mitosis produces two daughter cells which are identical to each other. While in meiosis “four haploid” daughter cells are produced. It is a highly systematized cell division process as the spore or gamete produce must comprise one member of each homologous pair of the chromosomes. The crossing over results in genetic exchange between the non-sister chromatids of “homologous chromosomes”. Meiosis plays a significant role during the alternation of generation in plants and acts as a bridge between the sporophyte stage and gametophyte stage. During meiosis cell division, haploid gametes or spores are produced whereas mitosis produces daughter cells which are genetically similar to each other. During meiosis the pairing of homologous chromosomes occurs by synapsis which separate during anaphase.

Answer:
Explanation:
The abundance of volcanoes and earthquakes along the Ring of Fire is caused by the amount of movement of tectonic plates in the area. Along much of the Ring of Fire, plates overlap at convergent boundaries called subduction zones. As rock is subducted, it melts and becomes magma
