Glucocorticoid steroid hormones are secreted by adrenal glands by stimuli arising from the hypothalamus of the brain. Adrenal glands are situated at the upper poles of the right and left kidneys. Glucocorticoids are usually secreted in response to stress.
Natural indicators are important because they relate information about the acidity or alkalinity of a substance by demonstrating a shift in color which inform the observer about the pH level of the concerned material.
Natural indicators possess useful chemicals which relate information about pH level and because of this they are used in manufacturing of chemical indicators.<span />
Answer:
The answer is D, hydrogen bonds.
Explanation:
Recently, I am studying medical biochemical products and believe that with biotechnology, we can have a much healthier body and a better quality life . This is the product I have been researching recently.
tissue microarray
: Creative Bioarray provides custom tissue arrays to help scientists efficiently analyze gene and protein expressions in multiple tissue samples. Tissue microarray is a high-throughput technique that allows rapid gene expression and copy-number surveys of large numbers of different tissue specimens. In addition, it represents a technical revolution for highly effective use of human tissue specimens, which are both difficult and expensive to obtain in enough amount and case number.
Based on the availability of more than 500,000 human and 30,000 animal samples in our tissue bank, we have constructed high quality tissue arrays to satisfy customers' special requirements.
We have also established standard operation procedure in custom array service. Our tissue microarrays are produced by re-locating tissues from conventional histological blocks. Typically, 40 to 1,000 cylindrical formalin-fixed and paraffin-embedded tissue cores can be densely and precisely arrayed into a single paraffin block. From the block, up to 300 serial 4-8 μm thick sections can be produced and placed on individual glass microscopic slides.
