Answer:
b. chemoautoptrophs
Explanation:
They are called chemotrophs; this means that they obtain their energy from chemical reactions.
1. Proteins are made from subunits called amino acids. There are 20 different amino acids which are responsible for the variation of proteins. Those amino acids are linked together by peptide bonds and form polypeptide chains. According to the polypeptide structure, there are 4 levels in protein structure as primary structure, secondary structure, tertiary structure and quaternary structure.
2. Starch is a type of carbohydrate. Hence, the subunits of starch are sugar molecules which are called as glucose. The elements of glucose are C,H,O. By linking glucose units with 1-4 alpha glycosidic bonds, the polysaccharide chain is formed. Hence, starch is also a polysaccharide<span>.

3. DNA is made from subunits called nucleotides. Nucleotides consist of deoxyribose, phosphate group and nitrogenous base.
There are two types of nitrogenous base as purines and pyrimidines. Adenine (A) and guanine (G) are purines and
thymine (T) and cytosine (C) can be seen as pyrimidines. Those nucleotides are linked together by sugar phosphate bonds which are formed between 5' phosphate group and 3' -OH group<span>.</span><span>

Answer:
The distance between the beginning of the first P wave and the first S wave tells you how many seconds the waves are apart. This number will be used to tell you how far your seismograph is from the epicenter of the earthquake. Measure the distance between the first P wave and the first S wave.

Answer:
The consumption of mosquitoes by bats and the control of flooding provided by tropical forests in mountainous areas of central america are examples of <u>ecosystem services</u>.
Explanation:
Ecosystem services can be described as the functions performed by parts of the ecosystem which benefit in regulating the ecosystem. These services offer a huge help to humans without the humans having to perform any work. For example, in the above question, humans are naturally getting rid of mosquitoes because the mosquitoes are being consumed by the bats. The floods in Central America are also being controlled by the tropical forests and humans have no work in it. Hence, both these examples show ecosystem services.
