Answer:

i already commented it but i want points anyways its 80 because 20x4 = 80. it said one gram equals 4 calories and there is 20 grams so basically 4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4

The question is incomplete, the complete question is;

Which of the following aspects of biotechnology is Not considered to be a moral or ethical issue?

a.research and testing on animals

b.cloning living material

c.reducing research cost

d.damaging the environment

Answer:

c.reducing research cost

Explanation:

Ethical issues arise when a particular course of action is at odds with the generally acceptable moral standard in the society.

Research and testing on animals is contested as an ethical issue by animal rights activists.

Cloning living material is prohibited among some sections of society and is also being contested as an ethical issue.

Damaging the environment the environment owing to biotechnology research is generally regarded as an ethical issue.

However, reducing research cost is highly acceptable in any research. It does not pose an ethical issue.

Which of the statements are true? Triacylglycerols (triglycerides) are carboxylic acids. Fats that contain more unsaturated fatt

astraxan [27]

<h2>The correct answer is given below:</h2>

Explanation:

Fats or lipid can be defined as high energy containing organic macro-molecules.
The basic molecule which makes up fat or lipid is Triacylglycerol.
A Triacylglcerol molecule is made up of one molecule of glycerol attached to three fatty acids molecules.
Here, the carboxylic acid groups of three fatty acid molecules are attached with the help of ester bonds to the three hydroxyl groups of one glycerol molecule.
Fatty acids are of two types, Saturated and Unsaturated.
Saturated fatty acid molecules can be defined as those in which the carbon atoms forming the hydrocarbon chain of the fatty acid molecule are linked to each other by single covalent bonds. The structure of saturated fatty acid molecule is linear or straight.
Unsaturated fatty acid molecules can be defined as those in which there are presence of one or multiple double covalent bonds in between the carbon atoms forming the hydrocarbon chain of the fatty acid molecule.
These double bonds in unsaturated fatty acid molecules form kinks or bend in the structure of the fatty acid .
In lipid or fat, the fatty acid molecules associate with each other by hydrophobic or Van der Waals forces of interactions.
In saturated fat, due to the linear structure of the fatty acids, the fatty acid molecules associate close to each other thereby forming a compact fat molecule with high melting point. This causes them become solidified at room temperature.
In unsaturated fat, the presence of kinks or bends in the fatty acid molecules results in the generation of fat molecules whose structure is not compact due to the presence of spaces in between the fatty acid molecules. These fats have a lower melting point which causes them to be liquid at room temperature.
The first statement is FALSE as triacylglycerols are formed by the esterification of three molecules of fatty acids with one molecule of glycerol.
The second statement is TRUE as unsaturated fatty acids have lower melting point than saturated fatty acids.
The third statement is FALSE as saturated fats have higher melting point than unsaturated fats.
The fourth statement is TRUE as triacylglycerols are formed by the esterification of three molecules of fatty acids with one molecule of glycerol.
The fifth statement is TRUE as unsaturated fats have lower melting point and so they are liquid at room temperature.
