'Poly' means two or more, so that is obviously the answer.

Answer:

D. polyunsaturated

Explanation:

A fatty acid consists of carbon atom chain linked by chemical bonds some of which may be double bonds.Polyunsaturated Fatty Acid also known as PUFA is characterized by the presence of two or more carbon double bonds in the chain. In case the carbon chain contains only one single double bond, the resulting fatty acid is known as monounsaturated fatty acid.So option D is the required option in this case.

What are some examples of how electrolysis is used in scientific research ?

charle [14.2K]

Answer:

Explanation: Perhaps the most familiar example of electrolysis is the decomposition (breakdown) of water into hydrogen and oxygen by means of an electric current. The same process can be used to decompose compounds other than water. Sodium, chlorine, magnesium, and aluminum are four elements produced commercially by electrolysis.

Nancy and Hiyang are training for a race. They entered some of their training notes in a chart. Which information should be adde

Mnenie [13.5K]

The information that should be added to the chart in order to find out who ran a greater distance is THE UNITS USED TO MEASURE DISTANCE EACH DAY.

In science, the use of units if very important and each record made must be accompany with relevant units that are appropriate for the measurement taken. If units are not used along with data, it will be very difficult to quantify the values that are recorded. Scientists all over the world use SI units in their works in order to ensure uniformity.

1. For a mixture of pure hexane and pure dimethylformamide, the dimethylformamide layer will be found as:______.a. the top layer

castortr0y [4]

Answer:

1. the bottom layer

2. aqueous HCI

3. the top layer

4.aqueous NaOH

5. mostly in the diethyl ether layer

Explanation:

Pure dimethylformamide is considerably more polar than hexane hence thee two solutions will form two phases with the pure dimethylformamide as the bottom layer.

If we want to extract aniline from chloroform, HCl must be added in order to give a salt that can be extracted into the aqueous layer.

For a mixture of methylene chloride and diethyl ether, the diethyl ether layer will be found as the top layer since it is considerably less polar than methylene chloride.

Benzyl alcohol can be extracted from a solution of chloroform by adding NaOH and extracting it into an aqueous layer.

A large partition coefficient for the extraction of naphthalene into diethyl ether from water means that naphthalene will be found mostly in the diethyl ether layer.

Help on science please!

erik [133]

Answer:

See explanation.

Explanation:

1. Forrest: From 425,000,000 to 300,000,000 is a change of 125,000,000. Divide the 125,000,000 by 425,000,000 to get the percent change:

125,000,000 / 425,000,000 = .294, which is a 29.4% change, a decrease.

2. Population: From 4,500 to 326,500,000 is a change of 326,495,500. Divide 326,495,500 by 4,500 to get the percent change.

326,495,500 / 4,500 = 72,554.55 which is a change of 7,255,455% change, an increase.

3. Conclusion: The growth in population required living area. People needed farms, houses, cities, and communities to live in. Forests were cleared to make room for the people to live. Forests are also used to provide building materials. The population increase contributed to the decrease in forest lands.
