Answer:
Succession is not ever guaranteed to stop in any area due to the possibility of natural disasters, climate change, and disease. The climax within an area my exist for many years but the area always has the potential to be disrupted by unexpected events that may damage plant life.
Explanation:
The common characteristic of those two organisms is hard spherical shells (exoskeleton).
Foraminiferans are single cell marine eukaryotes divided into granular endoplasm and transparent ectoplasm. Foraminiferans are enveloped with tests, hard shells, usually composed of calcium carbonate (sometimes from organic compounds or silica).
Coccolithophore is a unicellular, eukaryotic alga with special calcium carbonate plates (or scales) of uncertain function (coccoliths). Each unicellular alga is enclosed in its own collection of coccoliths, the which make up its exoskeleton- coccosphere.
Answer:
The options
a. sympatric speciation; vicariance
b. allopatric speciation; vicariance
c. sympatric speciation; dispersal
d. allopatric speciation; dispersal
The CORRECT ANSWER IS d.
d. allopatric speciation; dispersal
Explanation:
Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).
Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.
In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
You can use a plotting compass or iron filings to detect a magnetic field:
1.put a piece of paper over a magnet (this stops the iron filings sticking to the magnet)
2. sprinkle iron filings onto the paper
3.gently tap the paper to spread the filings out
4.observe and record the results
