Question

1. lipids are oily. do they mix with water? 26. what are proteins made from? 27. what cell organelle makes proteins? 28. complete the following makes proteins: protein types table. enzymes storage proteins defensive proteins/ antibodies hormonal proteins receptor proteins contractile and motor proteins structural proteins transport proteins 29. what are the main functions of nucleic acids? store and trans genetic info 30. how many strands make up rna? how many strands make up dna? 31. list the three types of rna and the structural shape of the rna in the table below. type of rna shape

Explanation:

1. Lipids are oily and do not mix with water as they are non - polar while water is polar.
2. Proteins are made from amino acids.
3. Ribosomes are the cell organelle that makes proteins.

28.

Protein Types	Function
Storage Proteins	Store amino acids
Defensive Proteins/Antibodies	Protect against pathogens
Hormonal Proteins	Regulate body functions
Receptor Proteins	Receive signals
Contractile and Motor Proteins	Enable movement
Structural Proteins	Provide structural support
Transport Proteins	Transport molecules

1. Nucleic acids (DNA and RNA) store and transmit genetic information. DNA has 2 strands and RNA has 1 strand.
2. RNA has 1 strand and DNA has 2 strands.
3. The three types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). mRNA has a linear shape, tRNA has a clover - leaf shape, and rRNA is part of the ribosome structure.

Answer:

1. Lipids are oily and do not mix with water because of their non - polar nature compared to water's polarity.
2. Proteins are made from amino acids.
3. Ribosomes make proteins.
4. See above table.
5. Nucleic acids store and transmit genetic info. DNA has 2 strands, RNA has 1.
6. RNA has 1 strand, DNA has 2 strands.
7. The three types of RNA are mRNA, tRNA, rRNA. mRNA is linear, tRNA is clover - leaf shaped, rRNA is part of ribosome structure.
