Answer: the true statements about eicosanoids includes options A,B,D,E
Explanation:
EICOSANOIDS are mostly produced from the precursor arachidonic acid, a C20 polyunsaturated fatty acid. They are broken down within seconds to inactive residues after synthesis.High concentrations of eicosanoids are necessary for effective action.The three major types of eicosanoids includes:
-prostaglandins,
- thromboxanes, and
- leukotrienes.
Depending on the above types mentioned, they play a role in inflammation, pain, fever promotion, blood pressure regulation, and blood clotting. They also influence the immune response and certain respiratory and reproductive processes.
However, eicosanoids are NOT transported in the blood stream to their site of action RATHER they exert their effects on the tissue where they are synthesized.
Explanation:
<em>(</em><em>P1V1</em><em>)</em><em>/</em><em>T1</em><em>=</em><em>(</em><em>P2V2</em><em>)</em><em>/</em><em>T2</em>
<em>(</em><em>1</em><em>5</em><em>X</em><em>5</em><em>)</em><em>/</em><em>2</em><em>9</em><em>7</em><em>=</em><em>(</em><em>p2x2</em><em>.</em><em>5</em><em>)</em><em>/</em><em>4</em><em>7</em><em>3</em>

His group's cube was made of <span>D) zinc. Looking up the density values of each of the choices, it can be seen that zinc has the closest density out of all of them. It's actual density has a value of 7.14 g/cm3. The others have density values that are way too far from the average density of 7.4 g/cm3.</span>
Answer:
2,3-dimethyl-2-butene > 3-methyl-3-hexene > cis-3-hexene > 1-hexene
Explanation:
According to Saytzeff rule, the more highly substituted an alkene is, the more stable it is. Since this is so, 2,3-dimethyl-2-butene will be the most stable of all the alkenes listed because it is the most substituted alkene.
Let us also note that terminal alkenes are the least stable because the pi bonds of the alkenes are least stabilized by alkyl groups. This implies that 1-hexene is the least stable alkene among the listed alkenes.
