Under a microscope, gram-positive bacteria (when dyed with the gram stain) appear in purple-colored structures due to the peptidoglycan cell wall.
<h3>What are gram-positive bacteria?</h3>
Gram-positive bacteria are microorganisms (bacteria) that may be colored with crystal violet stain due to the presence of a peptidoglycan-based cell wall.
In conclusion, under a microscope, gram-positive bacteria (when dyed with the gram stain) appear purple-colored structures due to the peptidoglycan cell wall.

The plant uses osmosis in order for liquid to pass through it.
The correct option is (c) LDL consists of cholesterol and protein.
One of the five main categories of lipoproteins, low-density lipoprotein (LDL), transports cholesterol throughout the body to the areas where it is required for cell repair and deposits it inside the artery walls. They need to be bound to proteins in order to pass through the hydrophilic blood.
The hydrophobic core of the LDL particle is made up of fatty acid esters of cholesterol, while the outer membrane is made up of unesterified cholesterol. The membrane contains a single copy of the hydrophobic apo-B protein, which facilitates the binding of LDL particles to particular cell-surface receptors.
Hence, LDL consists of cholesterol and protein.

Answer:
Domain
Explanation:
It is common to find in textbooks the classification of living organisms into five kingdoms: Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Plantae and Kingdom Animalia. It is now known that this classification has some serious flaws and that some kingdoms are no longer considered.
A widely accepted classification today is one that comprises one category above the kingdoms: domains. This classification was proposed by Carl Woese in 1977 and is based on molecular phylogeny data. According to Woese, there are three domains: Archaea Domain, Bacteria Domain, and Eukarya Domain.
