Answer:
1. circulate through the slug, engulfing bacteria
Explanation:
A sentinel cell is a cell of the immune system that is in charge of "eating" any kind of parasite in the body. In this case, it circulates through the slug and whenever it sees a bacterium, virus or foreign object, the sentinel cell engulfs it immediately.
Once the sentinel cell has eaten the bacterium, it produces several enzymes and substances that degrade the bacterium.
Out of the following given choice;
F. replaces the animal's soft tissues.
G. enters the animal's body cavity.
H. hardens before the animal decays.
J. mineralizes the animal's bones.
The answer H. This can be caused by hot pyroclastic flows or falling volcanic ash from the atmosphere following a volcanic eruption. The ash buries animals and plants intact without moving them and without completely crushing or burning them. Over time excess silica dissolved in the water often replaces soft bone materials molecule by molecule, creating an almost indestructible fossil (like petrified wood) that lasts for millions of years
Acrostics have sentences following each beginning letter that coincide with it.
this is how you would do it
D- write sentence relating to DNA replication
N-write your sentence relating to DNA replication

Answer:
True
Explanation:
DNA packaging in chromatin and the modifications are fundamental to the genetic expression.
Structure and modifications of chromatin regulate DNA metabolic processes, including transcription, recombination, reparation, etc.
Modifications that affect the way in which the DNI is packaged and used, but do not affect DNI sequences, are known as epigenetic modifications, and different enzymes are in charge of them.
Modifications might function by interfering between nucleosomes contact, or interacting with effector, or translating proteins.
Effector proteins initiate biological responses such as the activation or repression of transcription.
Packaging in chromatin has a big influence on genetic transcription. Genetic expression requires transcription factors that, once joined to genes regulatory sequences, initiate modification cascades that result in a gene expression or silence. Some of the chromatin modifications have been associated with genic activation or repression.
