What structure produces a thick secretion that can become gritty overnight, producing what is commonly called "sleep in the eyes"?
a. lacrimal apparatus
b. lacrimal caruncle
c. medial canthus
d. conjunctiva
The lacrimal caruncle structure produces a thick secretion that can become gritty overnight, resulting in what is commonly referred to as sleep in the eyes.
Eye discharge, or "sleep" in your eyes, is indeed a combination of mucus, oil, skin cells, and other debris that accumulates inside the corner of your eye while you sleep. Depending on how much of the liquid with in discharge has evaporated, it can be moist and sticky or dry and crusty. Eye mattering, ocular boogers, eye gunk, eye pus, and goopy eyes are other slang terms for eye discharge. Eye discharge, also known as "rheum," serves a protective function by removing waste products but also possibly hazardous debris from tear film and the anterior surface of your eyes.
The lacrimal caruncle is a small, pink, globular spot at the inner corner of the eye, also known as the medial canthus. It has both oil glands and sweat glands. The whitish material which sometimes accumulates in that region is from these glands. The tarsal plate is made up of connective tissue that supports the eyelids.

Select the descriptions that apply to the ribosome.a cellular structure that is composed of both RNA and proteina membrane‑bound organelle that stores digestive enzymesa cellular structure that is responsible for the synthesis of proteinsa membranous network associated with protein productiona membrane-enclosed organelle involved with cellular respiration
The descriptions that apply to the ribosome is a cellular structure that is composed of both RNA and protein.
All cells contain ribosome, which are macromolecular organisms that carry out biological protein synthesis (mRNA translation). To create polypeptide chains, ribosomes combine amino acids in the order dictated by the codons of messenger RNA (mRNA) molecules. The short and big ribosomal subunits are the two main parts of ribosomes. Each subunit is made up of numerous ribosomal proteins and one or more ribosomal RNA (rRNA) molecules (RPs or r-proteins). The translational apparatus also refers to the ribosomes and related components. A messenger RNA chain is produced from the DNA sequence that specifies the order of the amino acids in a protein. Messenger RNAs are bound by ribosomes, which use their sequences to determine the proper arrangement of amino acids to produce a specific protein. Transfer RNA (tRNA) molecules choose which amino acids to transport to the ribosome and then bind to the messenger RNA chain via an anti-codon stem loop. There is a specific transfer RNA that must precisely match the anti-codon of each coding triplet (codon) in the messenger RNA and carries the appropriate amino acid for incorporation into a developing polypeptide chain. After the protein has been created, it can fold to create a useful three-dimensional structure.

The three major types of contamination are physical contamination, chemical contamination, and biological contamination.
Contamination is the presence of refuse such as dust as well as particles during in the production and transportation processes. Any unwanted matter found inside the product is referred to as a contaminant. These contaminants have an impact on the product's or process's quality. Cross contamination occurs when unwanted matter has been introduced or transferred from one manufacturing process to the next.
Physical contamination would occur if a leak in the retaining containment contaminated the product inside.
An example of chemical contamination is when a product would be stored in a container which it previously held some other product but was not cleaned properly. The remaining product's chemical composition may introduce impurities into the new product, contaminating it.
Bacteria may thrive in biological contamination if the container also isn't properly cleaned and dried. The contaminated container then will affect the product, potentially introducing microbes into the batch.
