Answer:
Bone.
Explanation:
Calcium is one of the important element present in the body. Calcium plays an important role in the muscle contraction. The calcium ions also acts as a signalling molecule during cell signalling.
The calcium is present in our extracellular fluids, bones, and teeth. The major constituent of calcium is present in the bone. The bone consists of around 90% body;s calcium.
Thus, the correct answer is option (b).
Upregulation of vasopressin and oxytocin in the spinal cord using microcatheter interventions could increase monogamy among meadow voles. the correct answer is option(e).
In contrast to non-monogamy, monogamy is a type of dyadic interaction in which an individual has only one partner during their lifespan or, alternatively, just one partner at any given moment. The phrase is also used to describe how some animals behave in social situations, specifically the status of having just one mate at any given time.
Inhibitory interneurons may be activated by oxytocin and vasopressin across subcortical and possibly cortical networks, including reward pathways, to moderate their effects. Brain areas that are important for maintaining behavioral and physiological equilibrium are where oxytocin and AVP are largely produced. These two peptides are produced by several cells in distinct areas of the brain, including the supraoptic nucleus (SON) and paraventricular nucleus (PVN) in the hypothalamus.

Materials eliciting increased tongue flicking and prey attack in garter snakes were isolated from both earthworm and fish prey. New extraction methods based on chloroform-methanol mixtures are valuable adjuncts to the more typical aqueous preparations. Both high- and low-molecular weight components from earthworms and fish were active. The similarity between the active chemicals in these two classes of prey was established using several methods of analysis.
The optic nerve swelling as it enters the eye through the optic disk is known medically as papilledema.
<h3>What results in eye papilledema?</h3>
Increased pressure from the brain and CSF on the optic nerve causes papilledema. The nerve swells as a result of the pressure as it enters the eyeball at the optic disc.
<h3>What causes papilledema most frequently?</h3>
The most frequent causes of papilledema without IIH were cerebral venous sinus thrombosis, intracranial tumor, and intracranial hemorrhage.
<h3>What occurs when a person has papilledema?</h3>
The following list of papilledema symptoms is possible: loss of vision or blurred vision The optic nerve, which regulates your vision, is subjected to physical pressure as a result. Blurred vision or visual loss in one or both eyes are common symptoms of optic nerve compression.

Answer: They may be prokaryotic is false.
Explanation:
Protists are eukaryotic organisms i.e they have membrane bound organelles and Nucleus. They are neither plants,animals or fungus. Protists have many form of nutrition and they may be aerobic or anaerobic.
Some protists photosynthesized like algae while others are heterotrophs
They may be unicellular or multicellular.
Some protists have cell walls while others don't.
