The ester bonds in lipids are found where the fatty acids of the lipid join to the glycerol back bone of the lipid.
Lipids are made from two kind of molecules namely Glycerol and Fatty acids. A glycerol molecule is made up of three carbon atoms with an alcohol group attached to each of the carbon atoms and hydrogen atoms occupying the remaining positions.
A fatty acids consist of an acid group at the end of the molecule and a hydrocarbon chain.
In a process called esterification, the acid group of the fatty acid joins to the alcohol group of the glycerol molecule and water is released resulting in the formation of a linkage called an ester bond.
Answer:
The correct answer is - option B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable.
Explanation:
The independent variable in a study or experiment is a variable that is subject to change or manipulated to see the effect on the result of the study by influencing the dependent variable. In this study, the independent variable that is manipulated is the presence of the pups to see what is led to the behavior of meerkats.
The dependent variable is a variable that is influenced in a study by the independent variable and led to the result of the study as the frequency of sentinel behavior is influenced by the presence of the pups so the dependent variable here is the frequency of sentinel behavior.
I believe the answer is A, Ray crystallography
Answer:
The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground. Volcanic rocks are formed from lava that flows on the surface of the Earth and other planets and then cools and solidifies.
