The correct answer will be- the Pineal gland
Explanation:
The endocrine system is a system of glands which controls the body functions by secreting chemical messengers called the hormones.
The endocrine gland which is found in the middle part of the brain is called the pineal gland which is associated with the wake-sleep cycle of the body by producing a hormone called melatonin.
Thus, the pineal gland is the correct answer.
The right answer is <em>Bacillus.</em>
The pH-sensitive green fluorescent dye conjugates (available for <em>E.coli</em> and <em>Staphylococcus aureus</em>), give an accurate and faster results than other phagocytosis assay.
These conjugates are non-fluorescent in the extracellular medium (at neutral pH), but fluoresce will be brightly green at acidic pH such as in phagosomes, which makes it an ideal tool for phagocytosis assay.
