Low calcium levels in the <em><u>blood</u></em>
Explanation:
In primary hyperparathyroidism, one or more of the parathyroid glands is overactive. As a result, the gland makes too much parathyroid hormone (PTH). Too much PTH causes calcium levels in your blood to rise too high, which can lead to health problems such as bone thinning and kidney stones. <em> </em><em>this</em><em> </em><em>w</em><em>i</em><em>l</em><em>l</em><em> </em><em>h</em><em>a</em><em>p</em><em>p</em><em>e</em><em>n</em><em> </em><em>i</em><em>f</em><em> </em><em>p</em><em>a</em><em>r</em><em>a</em><em>t</em><em>h</em><em>y</em><em>r</em><em>o</em><em>i</em><em>d</em><em> </em><em>h</em><em>o</em><em>r</em><em>m</em><em>o</em><em>n</em><em>e</em><em>s</em><em> </em><em>g</em><em>o</em><em>t</em><em> </em><em>h</em><em>i</em><em>g</em><em>h</em><em> </em><em>i</em><em>n</em><em> </em><em>h</em><em>u</em><em>m</em><em>a</em><em>n</em><em> </em><em>b</em><em>o</em><em>d</em><em>y</em><em>.</em><em>.</em>
Answer:
hydrophilic- attracts water
hydrophobic- repels water
Explanation:
A cell membrane is a bilayer of phospholipids. They have a hydrophilic phosphate heads, and hydrophobic fatty acid tails.
so in the cell membrane they would arrange like this:
The heads are point outwards as they attract water, and tails inwards as they repel water.
Hope this helps!
That would be Chemoautotrophic
