Prokaryotic cell structure
24,50 € Add to basketProkaryotic cells are unicellular organisms without a nucleus,
containing circular DNA, ribosomes, and a cell wall, enabling
basic functions and rapid adaptation.
-
Septate filamentous fungi
24,50 € Add to basketSeptate filamentous fungi have hyphae divided by septa,
allowing internal transport, decomposition, and roles in
ecology, industry, and disease. -
Staphylococcus aureus bacteria
24,50 € Add to basketStaphylococcus aureus is a common skin and nasal bacterium
that can cause infections, spread by contact, and sometimes
show antibiotic resistance. -
Streptococcus bacteria
24,50 € Add to basketStreptococcus bacteria show cells and tissues, explaining
transmission, respiratory infections, and antibiotic control
processes. -
Streptococcus pyogenes bacteria
24,50 € Add to basketStreptococcus pyogenes is a Gram-positive bacterium causing
throat and skin infections, spreading through direct contact and
potentially leading to serious complications. -
Structure and formation of DNA
24,50 € Add to basketStructure and formation of DNA. This double helix molecule
stores genetic information through sequences of nucleotides and
nitrogenous bases. Its enzymatic replication process allows the
precise transfer of the biological code during cell division for
inheritance purposes. -
Template (Copy)
24,50 € Add to basketMerkel cells are specialized skin mechanoreceptors located
in the epidermis, associated with nerve endings, enabling
detection of touch, pressure, and texture. -
Template (Copy)
24,50 € Add to basketThe mast cell is an immune cell that releases histamine and
mediators, playing a key role in allergic reactions, inflammation,
and defense against pathogens. -
The cataract surgery process
24,50 € Add to basketCataract surgery process. The process details the extraction of
the opaque lens through ultrasound phacoemulsification and
its subsequent replacement with an artificial intraocular lens.
The intervention is a brief surgical procedure to restore clear
vision for the patients. -
Trichophyton fungi
24,50 € Add to basketTrichophyton fungi are dermatophytes that infect skin, hair,
and nails, causing ringworm such as athlete’s foot through
keratin degradation and contact transmission. -
UV-induced DNA damage
24,50 € Add to basketUV-induced DNA damage occurs when ultraviolet radiation
breaks molecular bonds, leading to mutations, cellular
dysfunction, and increased skin cancer risk.
