The correct answer is: chemoautotrophs

Since these bacteria obtain energy by the oxidation of electron donors (inorganic hydrogen sulfide) in their environments (chemical reactions) we can classify them as chemotrophs. In addition, they synthesize all necessary organic compounds from CO2 so they are autotrophs (opposite from heterotrophs that are unable to fix carbon).

A land developer and several ecologists are discussing how a parcel of private land should be developed with housing while savin
FromTheMoon [43]

Options for the question have not been provided. They are as follows:

A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

B) The isolated hectare plots increase the ability of individuals to disperse from one habitat to another.

C) The separate 1-hectare plots are less vulnerable to edge effects.

D) The large plot will create more inbreeding in many species.

Answer:

A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

Explanation:

In the given case, 20 hectares of land has been allocated to natural habitat. This means that natural flora and fauna will flourish here without any human interference. In this situation it is better to have an intact 20 hectares area at one side of the land, rather than having 20 separately spread out 1 hectare areas. This is because having one large piece of land at one side will reduce the edge effect.

Edges occur where two different habitats meet. While edges can be beneficial when it comes to natural habitats because the boundary habitat increases overall biodiversity, it can be detrimental when the edges are due to human settlements. It will be difficult to avoid human interference as the natural habitats are scattered among human settlements. Each individual plot will also get less area due to which it will be difficult for all the species to accommodate comfortably. Many animals can venture out in search of food which can be dangerous to both animals and humans. It is better to have a big separate land at one corner so that everyone can survive peacefully.

What is the difference between pollen and spores?
Stella [2.4K]

Answer:

Spores are used by groups of ancient plants and fungi in one stage of their reproduction. ... Spores grow into intermediate plants called gametophytes. Neither of these groups of plants produces flowers. Pollen is used by flowering plants to fertilize seeds.

If the na+ voltage-gated channels in a muscle cell open, what will be the result?
sammy [17]
If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.
