Which response represents the potential risks of a biohazard exposure to the facial mucous membranes of the eyes, nose, or mouth
Assoli18 [71]

When exposed to the mucous membranes on the face, biohazards can contaminate the eye as well as enter the circulation and stomach.

  • Biological compounds that endanger the health of living things, particularly humans, are referred to as biohazards, sometimes known as biological hazards.
  • Medical trash or samples of microorganisms, viruses, or toxins (from a biological source) that may be harmful to human health are examples of biohazards.
  • Bacteria, viruses, parasites, and molds or fungi are examples of biological health risks.
  • When they come into touch with skin, are eaten, or are inhaled, they can be harmful to human health.
  • They have the potential to spread diseases such parasite infections, tetanus, lung infections, and food poisoning.
  • The method via which a person can come into touch with a dangerous material is referred to as an exposure pathway. There are three primary exposure routes: direct touch, ingestion, and inhalation.

Energy flows through an ecosystem in one ____, from the sun or organic compounds to ____ and the to various ____ . ((HELP ME PLE
vlabodo [156]
Hi!

Energy will flow through an ecosystem in one <em>direction, </em>from the sun or inorganic compounds to<em> autotrophs </em>and then to various <em>heterotrophs. </em>

The energy flow in an area will be delivering light energy to <em>autotrophs</em>, which make their food from the energy the sun produces. 

The energy flow also delivers energy via inorganic compounds to <em>heterotrophs</em>, which do not make their own food.

Hopefully, this helps! =)

When RNA is processed in the nucleus and made ready for transfer out into the cytoplasm for protein synthesis, which of the foll
IRISSAK [1]
Answer:
Letter E - exons are cut from the strand and removed

Explanation:

Letter A and B are incorrect because the poly-A tail and guanine cap are added to the 3’ and 5’ end respectively. They aid in translation of the mRNA, while serving as protection. The poly-A tail is repeated adenine nucleotides, while the guanine cap is a modified guanine nucleotide.

Letter C is incorrect because alternative splicing is one mechanism for generating variation, and is thought to be one of the reasons for why humans have smaller genomes than other organisms and still maintain high complexity. Alternative splicing is incredibly important because it produces more than one transcript from a pre-mRNA.

Letter D is incorrect because introns are the non coding portions of the mRNA. They are excised to make a smaller mRNA transcript, and one that contains all the protein genes.

This letter E is the correct answer, because exons are the coding portions of the mRNA, and are not excised during RNA processing.

Hope that helped! If I made a mistake, please let me know.
