Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a:________
sweet [91]

Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a Tuff.

  • A form of rock called tuff is created when volcanic ash is blasted from a vent during an eruption.
  • The ash is transformed into a rock after ejection and deposition. Tuff is defined as rock with an ash content of more than 75%, whereas tuffaceous refers to rock with an ash content of 25% to 75%.
  • The thickness of tuff often decreases with distance from the volcano and is usually greatest close to the volcanic vent. The typical shape of a tuff deposit is that of a "lens," not a "layer."
  • Tuff may also be thickest on the vent's side that faces away from the wind or on the side facing the direction of the blast.

A phagocytic cell has a mutation in a gene for a hydrolytic enzyme that renders the enzyme nonfunctional. What is the most likel
pshichka [43]

Answer: The phagocyte’s ability to destroy the ingested pathogen is compromised and it will become inactive.

Explanation:

There are different hydrolytic enzymes. Lysozyme attacks cell walls of gram positive bacteria. Elastase is a protease. Collagenase attacks collagen, produced by some bacteria. Plasminogen activator is also a protease.

Loss of function of any one of these enzymes will reduce or prevent the breakdown of bacteria in the phagosome (vacuole) so that the phagocyte is inactivated.
