Eukaryotes are organisms that have evolved membrane-bound organelles such as mitochondria, Golgi apparatus, and in the case of p

lants chloroplasts. Eukaryotes may be multicellular organisms consisting of many cell types which form different tissue structures. Cell membranes and cell walls are composed of a variety of lipids, proteins, and carbohydrates each which provides structure and function to the eukaryotic cell.
Which macromolecule is a primary component of cell walls, and which argument provides evidence for how the structure of this molecule relates to its purpose within the cell wall?

A
Lipids are water soluble fatty acids that are the primary component of cell walls; they regulate water uptake by the cell because they form carbon chains.
B
Lipids are water insoluble fatty acids and the are the primary component of cell walls; they protect the cell and help maintain its shape because they form carbon rings.
C
Carbohydrates like cellulose and chitin are the primary component of cell walls; they repel and prevent excess uptake of water because they form rigid linear carbon chains.
D
Carbohydrates like cellulose and chitin are the primary component of cell walls; they protect the cell and help maintain its shape because they form chains of rigid carbon rings.

A trait that occurs in 900 individuals out of a total of 1,800 individuals occurs with a probability of
olchik [2.2K]

Answer: 0.5

Explanation:

Number of people with traits = 900

Total number of individuals= 1800

To find the probability with regards to the question, we divide the number of individuals having the traits by the total population of individuals. This will be:

= 900 / 1800

= 0.5

Which statement best describes the relationship between proteins and nucleic acids?
Iteru [2.4K]
Although the options are not provided, the statement best describing the relationship is nucleic acids provide blueprints for the construction of proteins.
Messenger RNA molecules (mRNA) take instructions from DNA molecules and take the code out of the nucleus. There, ribosomes work with the RNA molecules to produce a chain of amino acids, which in turn links and folds in a specific manner to form a protein molecule.
