It stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include intermediary metabolism, growth, protein synthesis, and reproduction (cell division). The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.

Answer: N. pubens has found a place within the existing food web in its new environment.
Explanation:
The statement that best explains the impact that N. pubens has on its environment is that "N. pubens has found a place within the existing food web in its new environment".
From the information given, it's stated that the Rasberry crazy ant (Nylanderia pubens) was accidentally introduced in Texas and it attacks livestock, displace existing species, and damage electrical equipment.
It's further stated that it consumes "honeydew," a sugary liquid substance secreted as a waste product by aphids, which suck the sap out of plants.
This shows that it has found a place within the existing food web in its new environment.
Secretin is a hormone produced in the intestines that promote the release of insulin from pancreatic islet cells.
Discussion about secretin:
- When fatty acids and acidic chyme are present, secretin is released. It performs a number of functions by attaching to secretin receptors, the majority of which are related to digestion and acid neutralization.
- In its principal function, secretin tells the pancreas to release bicarbonate ions into the pancreatic juice, raising the pH to between 8 and 8.3 in order to neutralize the acidic chyme. The pancreatic juice's digesting enzymes may function at their best as a result, safeguarding the duodenum's lining.
- Additionally, secretin controls the pyloric sphincter's tightness, gastrin release, HCl synthesis, and small intestine motility.
As a result, secretin also encourages the pancreas to produce more insulin in response to ingesting glucose.
