El vidrio no templado contiene burbujas de aire microscópicas que se expanden y contraen a medida que el vidrio se calienta y enfría, especialmente a temperaturas extremas como durante el enlatado y la congelación. Cuando esas pequeñas burbujas de aire se expanden, hacen que el vidrio se rompa o incluso explote. Espero que esto haya ayudado, por favor, dé cinco estrellas y mentalmente.
Answer:

Explanation:
Cytochalasin D prevents the addition of monomers at plus ends of existing filaments. When the concentration of G-actin in the cytosol is below the critical concentration, the loss of monomers at <span>minus ends</span> of existing filaments eventually results in their shortening. This occurs despite the pool of available G-actin in the cytosol.
Answer: These may be:
- physical defenses (1st line)
- chemical defenses (2nd line)
Explanation:
Plants employ several methods in order to defend themselves from pathogens. These may be physical defenses or chemical ones. Several have adaptations to their surfaces that prevent the entry of pathogens, called physical barriers such as
- thick waxy cuticles
- thorns, which are modified plant branches
- spines, which are modified plant leaves
- gall production at infected sites to prevent pathogenic spread
Chemical defenses include the production or secretion of:
- defensins
- antimicrobials such as tannins or resins
- gum at areas facing pathogenic attacks
