I think the correct answer among the choices presented is option B. The major reaction of the unsaturated compounds is addition. This type of reaction is a reaction in wherein one molecule combined with another molecule forming a larger molecule and no other products.

Why do some cells make food molecules?

kvasek [131]

Answer:

All living cells release energy from food molecules through cellular breathing and/or fermentation. Some cells make food molecules using light energy through the process of (making food from light).

Making food from light- Photosynthesis

Breathing- Respiration

All living units give out power for a given time from food small complex units through formed of small units breathing and or fermentation. Some units make food small complex units using light power for a given time through the process of (making food from light).

My barometer is reading 1253 torr. What is the pressure in mmHg?

kobusy [5.1K]

Answer:

The pressure in mmHg is 1253 (option C)

Explanation:

Two quantities are directly proportional if when multiplying or dividing one of them by a number, the other is multiplied or divided by that number. In other words, the magnitudes are directly proportional when one magnitude increases and so does the other in the same proportion; or when one magnitude decreases and so does the other in the same proportion.

The rule of three or is a way of solving proportionality problems between three known values and an unknown value, which can be applied to directly proportional quantities as follows:

a ⇒ b

c ⇒ x

So $x=\frac{c*b}{a}$

where a, b and c are data and x is the unknown value to be calculated.

In this case, knowing that 1 Torr = 1 mmHg, the rule of three can be applied as follows: if 1 torr is equal to 1 mmHg, 1253 torr is equal to how many mmHg?

$pressure=\frac{1253 torr*1 mmHg}{1 torr}$

pressure= 1253 mmHg

The pressure in mmHg is 1253 (option C)
