The best and most correct answer among the choices provided by your question is the first choice or letter A. Margarines are products <span> made up of fatty acids that are derived from alkenes.
</span>The main ingredients in most margarines are vegetable oils like soybean or safflower oil.Vegetable oils<span> are mostly unsaturated, which is a problem because unsaturated oils are liquid at room temperature and cannot be used as spreads.

Answer:
the answer is A I just answered this one I hope it helps
The regression equation is:
y = 1.15 – 0.251 x₁ + 0.078 x₂ + 0.306 x₁x₂
<span>
<span>
<span>
Where,
x₁ = -0.2508
x₂ = 0.0777
x₁x₂ = 0.3058
Inserting the values,
<span>
<span>
</span></span>y = 1.15 – {0.251 × (-0.2508)} + {0.078 ×(0.0777)} + {0.306 × (0.3058)}
</span></span></span>
y = 1.15 - (- 0.0629508) + 0.0060606 + 0.935748
y = 1.15 + 0.0629508 + 0.0060606 + 0.935748
y = 1.3125862
Answer:
x₁ and x₂ are main effects (a type of tuna and type of packing liquid) that contribute significant information for the prediction of <span>y.</span>
Answer:
Test Tube 2 (<em>S. sonnei)</em>
Explanation:
Triple sugar iron agar test is the microbiological assay used to test the fermentation reaction performed by the bacteria. The fermentation process differs based on substrate and the acids formed as a byproduct.
The test is based on the byproduct formed as a result of fermentation. The test tube contains 1% lactose, 1% sucrose and 0.1 % glucose, ferrous sulphate, phenol red pH indicator.
When the bacteria ferment any of the three sugar, the medium turns yellow.
In test tube 1- The tube shows pink slant, pink butt and no black precipitate which indicates that no fermentation took.
In test tube 2- the tube shows pink slant, yellow butt and no black precipitate due to fermentation of Glucose only due to alkali acid reaction.
In test tube 3- the tube shows yellow slant and yellow butt which shows that glucose and either lactose or sucrose has been fermented.
Thus, test tube 2<em> (S. sonnei</em>) is the correct answer.
