sertanlavr [38]3 years ago

Answer:A good index fossil is one with four characteristics: it is distinctive, widespread, abundant, and limited in geologic time. Because most fossil-bearing rocks formed in the ocean, the major index fossils are marine organisms. That being said, certain land organisms are useful in young rocks and specific regions.

SIZIF [17.4K]

One factor that would limit the settlement on top of living organisms is the panels hang vertically from the side of a dock.

The factors that affect settlements can explain how an organism adapts to its environment. There can be numerous factors based on the situations that can limit the settlement of an organism in its new environment. Competition, predation, disturbances, resources, etc can affect the establishment of a species in an area.

A set of panels hanging vertically can hinder the settlement on top of living organisms. Many organisms are known to survive in the harsh stormy seas and many are known to live in places where freshwater and ocean surface water mix (estuaries). But if the place where the animal such as crabs and snails have to reach is hung vertically it might be difficult for them to establish themselves as it will be harder for them to reach and hang on to the panels.

Compare and contrast what happens in mitosis and meiosis and discuss the importance of each process to a living organism.
Semenov [28]

In mitosis, the first stage is prophase. The nucleolus disappears and the two centrosomes begin to form the mitotic spindle. The spindle xtends between two opposite poles f the cell. Next is the metaphase. The centromeres of the chromatid pairs align at the center of the miotic spindle. Then anaphase, the centromeres will split that separates the chromatid pair. They are now called chromosomes. The last phase is the telophase. The chromosomes will then form a thread-like chromatin and for ache envelope, a nucleoli appears. <span>The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.</span>
