Answer:
The correct answer to the question: Suppose there is a mutation in a laminin-binding integrin gene that causes a loss of function in the cytoplasmic domains of the integrin. Which one of the following would you expect to observe as a result of this mutation?, would be, C) The strength of tissues would be decreased because the integrin could no longer associate with intermediate filaments in hemidesmosomes.
Explanation:
Through integrin receptors, laminin contributes to cell attachment, differentiation, strengthen of tissue phenotype, movement, and shape of the cell and support of tissue survival. Therefore if a mutation occurs in the laminin-binding integrin gene producing a loss in the cytoplasmic domains, the interaction after they bind would be affected, due to the integrin would be unable to signal the cytoplasm and the maintenance of tissue will decrease.
Hemidesmosomes, are intermediate filaments composed of a group of proteins that cross the plasma membrane such as integrin (α6β4), collagen (BP180 or BPAG2), protein CD151 and another type of protein placed exclusively in the cytoplasm called plectin and BPAG1e. These proteins interact in the cytoplasm. Inside the hemidesmosomes, the proteins of the basement membrane and the filaments inside the cell settled a chain of connections.
Answer:
Some have lifelong relationships with other organisms, called symbiotic relationships. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Commensalism: only one species benefits while the other is neither helped nor harmed

See explanation below.
Explanation:
Starfish, also known as sea stars, are marine organisms that belong to the Class Asteroidea. They are considered invertebrates because they lack a vertebral column. Moreover, most starfish species have five arms but some species can have up to 15!
Here are some characteristics that differentiate starfish from other organisms and make them so unique:
- Possession of tube feet.
- Most species have pedicellaria, claw-shaped structures with movable jaws.
- Radial symmetry
- They can possess from 5 to 15 arms.
- Do not possess brain.
- They can regenerate parts of their body.

Explanation:
the plasma membrane of a skeletal muscle fiber is called the sarcolemma. The sarcolemma invaginates into the cytoplasm of the muscle cell (sarcoplasm). This forms membranous tubules that pass across the muscle cells.
