Answer:
3. Second-order neuron cell bodies reside in the dorsal horn of the spinal cord.
Explanation:
The Anterolateral System, also called spinothalamic, carries information about pain, temperature, coarse touch or pressure, and itching and tickling sensations. This system mainly contains slow conduction fibers
The spinothalamic pathway can be subdivided into two: the neospinothalamic pathway the fibers project into the somatosensory cortex and the paleoespinothalamic pathway with projections at different points in the thalamus. The neospinotalamic pathway has the axons of the first-order neurons that establish synapses on second-order neurons, located in the dorsal horns of the spinal cord.
Answer:
E. Weather radio collars are the only practical means that park rangers have for tracking the movement of the rhinoceros in the park.
Explanation:
E. Weather radio collars are the only practical means that park rangers have for tracking the movement of the rhinoceros in the park.
Nowadays there is a lot of technology available for tracking and monitoring of wildlife in big areas. If these radio collars are falling off very frequently and the tranquilizer is being used a lot, it means the method they are using is not the best or very efficient for this type of big animals.
They can use for example GPS trackers in a microchip implanted below the rhinoceroses skin or <u>even inside the horn</u>. With this process the park rangers would just need to use the tranquilizer once to immobilize the animal for a little bit, implant the GPS tracker or microchip; <u>this device won't fall or slip off and won't do </u><u>any harm</u><u> to the rhinos either</u>. This procedure will reduce the risk of the collar falling off and the use of the tranquilizer every time it does fall. Additionally, with this trackers, the park rangers, supervisor or vet can access the information <u>24 hours a day, in real-time</u> from a computer or even an electronic device. This new technology even offers an alarm systems by SMS or calls every time an abnormal rhino activity is detected.
The answer is C, serve a different function.
In multicellular organisms, same types of cells makes up a tissue, and tissue makes up organs, then eventually organs work together as an organ system.
For example in humans, stomach cells makes up the stomach tissues, and stomach tissues makes up the stomach. stomach can help digest food and mix food molecules together. But in opposition, red blood cells is present in the blood tissue, however, their function is not to digest food, but is to transport oxygen.
Therefore, we can see that different cells serve a different function.
Out of the following given choices;
A Bowman's capsules
B afferent and efferent arterioles
C nephrons
D collecting duct
E glomeruli
The answer is D. Also known as vasopressin (a stress hormone)
acts on the receptors of the collecting ducts of the nephron during water
stress to increase water reabsorption. The hormone stimulates water reabsorption by stimulating insertion of
"water channels" or aquaporins into the membranes of kidney tubules.
Answer:
IN OLDEN TIMES:
A girl, when she reaches puberty is barred from entering the prayer room or performing any religious prayers during her menstruation. The only reason mentioned in our scriptures is that she is (ashudha) unclean during that period.
During ancient days, women would take bath in the river, pond or near the well. During the time when the girl would be menstruating, it would be awkward to bathe outside in the river as it would probably ‘pollute’ the water.
So, the ladies did not take bath. Since the ladies did not take bath, they were naturally termed ‘unclean’ during that time. Hence, their being barred from the clean’ places in the house, namely the prayer room or the kitchen.
However, Science has a different meaning for the menstruation. As per science, a woman is more irritable during those days because of a hormonal imbalance. Psychics claim that there is a different aura around a menstruating woman, maybe again a chemical reaction.
Segregating to pray requires a positive attitude and people tend to respond to the negative virations of a person standing with you; maybe that was the reason why a woman was barred from public places and the kitchen.
TODAY:
Times have changed,
It is the old saying of old people. But of a girl cooks during periods then it is not to become bad in taste or it won't get spoiled. The taste of food is going to be same as she cooks on other days. So I think this saying is wrong and girls can cook during their mensuratl days. It is a natural cycle and they r not responsible for it
