<span>When used in glaucoma, this drug blocks beta-1 and beta-2 adrenergic receptors resulting in decreased aqueous humor production: Timolol
Beta blocker is common medication in glaucoma, but many beta blocker is selective to beta-1 or beta-2. Nonselective beta blocker would be timolol.</span>
Nitrogen released from dead matter goes into soil, helping/feeding the plants, who in turn give us oxygen
The question is:
What may be observed as a result of the described mutation in an individual?
<span>1) Skin cancer due to UV rays </span>
<span>2) Darker blue pigmentation </span>
<span>3) A lack of alterase for other functions it may serve </span>
<span>4) The release of a different pigment color
The correct answer is B.
In this theoretical molecular cascade, we have three key parts, the blue2 gene, the blue2 operator and the enzyme alterase.
The enzyme alterase stops the expression of the blue2 gene by binding to its operator, and therefore the blue pigment protein.
The blue2 operator has a specific binding spot for alterase. If this binding spot is changed due to a conformational change, the alterase would not be able to bind to the operator and the blue2 gene could express undisturbedly, resulting in increased concentration of the blue pigment protein.</span>
Answer:
"Endocrine Organs and the Nervous system II. Nerves and hormones work together to regulate function of the human digestive system; they control muscular contractions and the rate of secretion from digestive organs. ... Several hormones coordinate digestive functions of the stomach, pancreas and gall bladder."
