Complete question:
Imagine a newly discovered biological molecule that is mostly hydrophobic in its structure. This new molecule will most likely be classified as a___________.
a. Proteins
b. Lipids
c. Nucleic acids
d. Carbohydrates
Answer:
b. Lipids
Explanation:
Lipids are the biomolecules that are mostly nonpolar in nature. Storage lipids such as fatty acids and oils have small or long chains of hydrocarbons. This makes them largely hydrophobic. Similarly, phospholipids have fatty acid chains that make their hydrophobic component. Steroids are also the lipids that have a distinct sterol nucleus in their structure. This makes then hydrophobic. Therefore, most of the lipids have structural components that make them largely hydrophobic molecules. So, the newly discovered molecule is most likely a lipid.

Answer:
Two or more elements,
Two or more elements,Chemically combined elements,
Two or more elements,Chemically combined elements,More and definite proportions.
Explanation:
A compoundcan be definedas a substance which is composed of two or more elements, that are combined together chemically.
These constituents elements are present in definite proportion and quantities. The composing elements of a compound can be separated only by the means of chemical procedures. A compound is composed of more than one type of atom.
Hence answer could be:
Two or more elements,
Two or more elements,Chemically combined elements,
Two or more elements,Chemically combined elements,More and definite proportions.
Answer:
The correct answer will be option-E
Explanation:
The autonomic nervous system or ANS activity in the brain is mainly controlled and regulated by the hypothalamus structure. The autonomic centres of the hypothalamus control the hormonal secretion adrenal medulla like adrenaline and norepinephrine.
The secretion of the hypothalamus controls the activity of the vasomotor center which help maintain the blood pressure.
Thus, option-hypothalamus is the correct answer.
Explanation: we will conclude this by the following characteristics:
1.organims that lack a proper nucleus.
2.they have membrane bounded organelles
3.they are tiny single cell oraganisms which cannot be seen by naked eye.
4.they are the oldest livinh organisms on earth
5.they are present in very harsh conditions like volcanic vents or at the bottom of the sea
