Biology

3 0

The independent SiO4 4- tetrahedra join with the Mg2+ and Fe2+ ions to generate the mineral olivine in the rock peridotite.  

Olivine is the naming of group-producing minerals, which are usually found in ultramafic and mafic rocks, like gabbro, basalt, diabase, dunite, and peridotite. They are generally green in appearance and exhibit constituents, which generally range between Fe2SiO4 and Mg2SiO4.

If your cells couldn't go through meiosis- how could this affect you?
Nonamiya [84]

Answer:

An organism would not be able to reproduce without meiosis.

Explanation:

Between meiosis and mitosis, meiosis is by far not as important. If you are a asexual organism, this would be NOT IMPORTANT whatsoever. If you are a sexual organism, this would LARGLY effect you. But on a world scale, this is NOT AS IMPORTANT.

This is because, without mitosis, you could not heal and would die much much younger since your cells could not be replaced. On the other hand, without meiosis, any organism that reproduces sexually would be unable to do so, which could lead to extinction in many, many species. This would not be harmful, however, to species that can also or mainly reporuduce asexually through budding, fragmenting, or sporing. So overall:

<u>Organisms that produce sexually would go extinct. </u>

This is the only real affect I can think of. Since meiosis does not  produce any cells aside from reproductive cells. And asexual organisms produce reproductive cells through other means.

1) Ecology is the scientific study of the distribution and abundance of organisms, the interaction among organisms, and the interactions between organisms and their abiotic environment. Ecologists try to understand the inner workings of natural ecosystems and the species they contain.

2) Ecosystems have no particular size. An ecosystem can be as large as a desert or a lake or as small as a tree or a puddle. If you have a terrarium, that is an artificial ecosystem. The water, water temperature, plants, animals, air, light and soil all work together.

3) The biotic factors of an ecosystem include all the populations in a habitat, such as all the species of plants, animals, and fungi, as well as all the micro-organisms. Also recall that the nonliving factors are called abiotic factors. Abiotic factors include temperature, water, soil, and air.

4) For aquatic ecosystems, these factors include light levels, water flow rate, temperature, dissolved oxygen, acidity (pH), salinity and depth.


Hope this helped. ;)
