Commensalism, in ecology, is a class of relationships between two organisms where one organism benefits from the other without affecting it. This is in contrast with mutualism, in which both organisms benefit from each other, amensalism, where one is harmed while the other is unaffected, and parasitism, where one benefits while the other is harmed.

Nerve fibers from the olfactory bulb project directly to ________. nerve fibers from the olfactory bulb project directly to ____

ohaa [14]

The olfactory cortex (nucus) of the temporal lobe is where the nerve fibers of the olfactory bulb projects directly. This cortex is where you get the smell sensation before determining what the smell actually is. The olfactory cortex is located on the medial aspect of the temporal lobe, particularly in the uncus or the piriform lobe. It is also called the Rhinoencephalon or the nose brain.

Thyroxine, an important hormone that controls the rate of metabolism in the body, can be isolated from the thyroid gland. If 0.4

MA_775_DIABLO [31]

Answer:

The molar mass of thyroxine is 18,2 g/m

Explanation:

To solve this we must apply the colligative property of cryoscopic descent whose formula is:

T° sv pure - T° sl = Kf x molality

So let's replace our values

5,444°C - 5,144°C = 5,12 °C/m x molality

0,3°C = 5,12 °C/m x molality

0,3°C / 5,12 m/°C = molality

2,5 m

Now you should know that molality is moles from solute in 1kg of solvent but you dont have 1kg you have just 10 g. Let's convert for the rule of three

10 g = 0'010 kg

If 1 kg has 2,5 moles of thyrosine, how many for 0,010 kg

moles = (0,010kg * 2,5 moles)/1kg

moles = 0,025

Now we have the moles of thyrosine in our solution and we were informed that we dissolved 0,455 g so let's get the molar mass (mass of compound for one mole)

moles = mass/ molar mass

molar mass = mass/moles

molar mass = 0,455g/0,025 moles

molar mass = 18,2 g/m

The theory of plate tectonics is supported by _______. The Eurasian and African plate are pushed away from the North and South A

anyanavicka [17]

Answer:

1. ridges and trenches (either answer is acceptable)

2. mid-atlanitc

3. subduction zone

4. molten

5. oceanic trenches

Explain:

6. Rocks in the ocean eventually get subducted back into earths mantle due to slab pull. New rocks form at mid-ocean ridges as ridge forces two plates to diverge.

To make new cells, humans undergo a process of cell division called mitosis. Before a cell goes through cell division (mitosis),

sashaice [31]

Before a cell goes through cell division (mitosis), it must grow and make a copy of its DNA which is termed as an Inter-phase.

Explanation:

Some tasks must be carried out by the cells before they undergo division: The cell must grow, it must copy the genetic material (DNA) present in it, and divide into two daughter cells. These steps carried out by cells are termed as cell cycle.

Cells that contains a nucleus or Eukaryota cells, there are two major phases called interphase and the mitotic (M) phase. that comprises the cell cycle.

In inter-phase, growth of the cell and making a copy of its DNA is carried out.

In mitotic (M) phase, the cell separation of the DNA in the cell into two sets and division of its cytoplasm takes place resulting in the formation of two new cells.
