Answer:

Option-B, C and E

Explanation:

Archaebacteria are a group of prokaryotes which can survive the extreme conditions. The archaebacteria which can survive very high temperature are called hyperthermophiles. The hyperthermophilic bacteria can survive temperature range between 70 t 125 °C observed in hydrothermal vents.

The archaea bacteria can withstand the high temperature as their membrane is adaptive. The membrane of the archaea is more stable due to the ether linkage which makes carbon less chemically reactive. The phospholipids possess a monolayer which decreases the layer fluidity and thus the unwanted movement of molecules.

The archaea also contain cyclopentane rings in the ester-linked phospholipids which allows tight pacing of the molecules which decrease the movement of solute into and out of the cell.

Thus, the selected options are correct.

In the cranial nerve model, which best describes the location of the optic chasma:________

eimsori [14]

Answer:

Cranial Nerves:

The cranial nerves are the set of 12 pairs of nerves which are originated from the brain. As they are responsible for some of the essential functions , such as vision, smell, and balance of the human body structure.

The 12 pairs of the cranial nerves are as as under:

The olfactory nerve
The optic nerve
The oculomotor nerve
The trochlear nerve
The trigeminal nerve
The abducens nerve
The facial nerve
The vestibulocochlear nerve
The glossopharyngeal nerve
The vagus nerve
The spinal accessory
The hypoglossal nerve,

It is very hard for the students to remember all the names of the cranial nerves as we can just recall them by memorizing the device-Old Opie Occasionally Tries Trigonometry And Feels Very Gloomy, Vague And Hypoactive.

Explanation:

Optic chasma:

The optic chasma originates as one of the cranial nerves, as it serves for the function of vision sense in human body. The nerves are responsible for carrying the set of information and data from the retina of the eye to the brain. As the communication between the two regions or part of the body, as they hold the capacity to carry the charges or information from the retina of the eye towards the brain.

Which cell is most important for the defense against parasitic organisms ?

Murljashka [212]

I'd say, ina general way, that the most imporant cells in defense against parasitic organisms are definitely white blood cels, the cells responsible for defeating antigens, pathogens and deseases.

Although these might be the most important ones in that specific task (defending against parasitic organisms), all the cells in the immune system, along with other non-cell things are important, since they all play a specific role indispensable in our immune system.

Hope it helped,
