Of the following given choices;
a. object discrimination problem
b. landmark discrimination problem
c. double dissociation problem
d. single dissociation problem
The answer is; A
Temporal lobe which spans both cerebral hemispheres of the brain and below the lateral fissure is significant in interpreting sensory information. Its communication with the hippocampus is also vital for the long-term memory. There is a visual area in the temporal lobe that processes and interprets visual information from the eye hence one is able to recognize objects.
Placenta
It also does not allow the maternal and fetal bloodstreams to mix
Chloroplasts because that is the substance that gives leaves its green colour and also helps in photosynthesis
Answer:
The correct answer will be option-
1. UV light strikes the skin and converts a steroid molecule into an inactive form of vitamin D.
2. Inactive vitamin D is transported to the liver where it is modified.
3. Vitamin D is activated under the influence of PTH.
4. Inactive, chemically altered vitamin D is transported to the kidneys.
Explanation:
Vitamin D is a fat-soluble metabolite which helps maintain the health of the bone by maintaining the calcium homeostasis.
The vitamin D is synthesized mainly in the liver and kidney from the biologically inactive precursor of vitamin D called ergocalciferol and Cholecalciferol.
The inactive vitamin is synthesized in the skin when the skin is exposed to UV rays. The UV rays convert the 7-dehydrocholesterol, a steroid molecule to Vitamin D3, This inactive vitamin is then transported to the liver where it is converted to 25-hydroxyvitamin D.
This vitamin D form is further metabolized in the kidney controlled and regulated by the Parathyroid glands.
