Answer:
Part A: Proteins are made from amino acid monomers. There are 20 different types of amino acids which make up all the proteins of the body. The amino acids are made up of a carbon atom which is joined to an amino group, a carboxyl group and a variant group, known as R. Nucleic acids are made up of 5 carbon sugar, phosphate group and nitrogenous bases. Hence, nucleic acids are made up of nucleotides.
Part B: Protiens are important molecule which carry out various functions of the body. They are involved in regulation of various body process. Some proteins are involved in the transportation of various molecules. Other type of proteins are involved in various immune functions and hence protect the body. For example, antibodies are proteins which defend the body against pathogens.
Nucleic acids are involved in the storing and expressing of genetic information. They also direct the body for protein synthesis.
Answer:
D.) Organism
Explanation:
On the basis of biological organization, one female arctic fox will be considered as an organism.
Biological organization refers to a hierarchy starts from simplest biological structure to complex biological structures that define life, such as from atoms to biosphere.
So, biome is the community of animals and plants having common characteristics according to the environment; species is also a group of living organism sharing similar genes; ecosystem include different groups with the physical (abiotic) environment and organism is the basic living system,that include at least one cell.
So, one female arctic fox will be termed as an organism and the correct option is D.
The polar head of a phospholipid is made of phosphate. The polar head has a negative charge that is made up of phosphate molecules. This polar region attracts water and is positioned outward to interact with the water.
I hope this helps!
Answer:
A liter is a cubic decimeter, which is the volume of a cube 10 centimeters × 10 centimeters × 10 centimeters (1 L ≡ 1 dm3 ≡ 1000 cm3).
Explanation:
Hence 1 L ≡ 0.001 m3 ≡ 1000 cm3, and 1 m3 (i.e. a cubic meter, which is the SI unit for volume) is exactly 1000 L.
