The basic structure of a steroid differ from other macromolecules such as carbohydrates by having a four ring structure whereas a carbohydrate do not have. A steroid is a group of organic substances which has four rings that are arranged in a certain configuration. Examples are testosterone, estradiol and lipid cholesterol. It will always have seventeen carbon atoms in its structure. Carbohydrates, on the other hand, are a group of organic substances that consist carbon, hydrogen and oxygen atoms typically in a 2:1 ratio of the hydrogen and oxygen atoms. So, it would have an empirical formula of Cx(H2O)y.
Answer:
oxygen
Explanation:
because it comes after water
Answer:
Effort = 125 N
Explanation:
Given
Load (L) = 500 N
Load distance (L.D) = 20 m
Effort distance (E. D) = 80 m
Effort (E) = ?
We have the formula that
E * E.D = L * L. D
E * 80 = 500 * 20
80E = 10000
E = 10000/80
E = 125 N
