Answer:

I believe that it increases (becoming more dense)

Explanation:

Well 0°C is freezing point so I think that in that state it will become a solid from a liquid and freeze into ice.

It increases because when you cool water, it’s particles become so close that it’s volume decreases and density increases

What is a pacu fish's predators/dangers

Zepler [3.9K]

he Piranha is one of the most efficient predators on the face of the earth. Granted it is not a large animal, with most only reaching about 5 1/2 to 10 inches (14 – 26 cm), but it is known world wide for its ferocious nature. They have razor sharp teeth and are opportunistic carnivores.

A frenzied attack by a group of Piranha will set the water churning. They will attack and eat all sorts of aquatic animals, insects, lizards and amphibians. They will also devour rodents, carrion (dead meat), and sickly or weakened land animals that venture into the water.

The teeth of the Piranha are triangular in shape with an exact fit in their jaw, comparable to a bear-trap. They are designed to puncture and slice the flesh from their prey. They can strip their prey to the bone in a matter of minutes.

These fish are a great source of fascination. Their natural behaviors have become fodder for the scripts of moviemakers looking for a sensational twist to excite and entice an audience. What could be more intriguing than creating a 'fear factor' from the behaviors of these provocative fish found in the "wild". Yet just like the Great White Shark and the Anaconda constrictor, also popular subjects of thriller movies, the Piranha’s behaviors are over-fantasized.

The Piranha does engage in a feeding frenzy that will "make the water boil" if only because a hungry school of fish are trying to reach the same limited food source. All that activity is bound to create water turbulence. A Piranha school generally only consists of about 20 or so fish, but in a feeding frenzy it can reach up to several hundred..

Piranhas are not always that deadly. Many species live solitary lives once they reach maturity and only four or five species pose any significant danger. Piranhas rarely attack people. Many experts believe they are actually timid fish, and shoal for protection. Even the most aggressive are thought to be not really dangerous until they are trapped and confined, and then attack in self defense. As a pet they are fascinating and beautiful fish, yet you can't hold or pet them. They are not affectionate and owners must be extremely careful, especially when handling them. They do have sharp teeth and an aggressive/defensive nature. Most Piranha bites are sustained when the fish are being handled, though that's not to say a hungry fish is never dangerous.

The majority of triglyceride digestion occurs in the small intestine facilitated by the enzyme

bixtya [17]

Answer:

pancreatic lipase

Explanation:

Enzymes from pancreas involved in triacylglycerol digestion are called pancreatic lipases and they catalyze the partial hydrolysis of triglycerides into a mixture of free fatty acids and acylglycerols. After digestion of lipids, monoglycerides and fatty acids associate with bile salts and phopholipids to form micelles. Micelles are structures that are necessary for the transport the poorly soluble monoglycerides and fatty acids to the surface of the enterocyte. But, micelles cannot be absorbed by epithelial cell, only freely dissolved monoglycerides and fatty acids can. Free fatty acids and monogycerids can just diffuse across the plasma membrane because of their nonpolar nature.

Some absorption (e.g. for cholesterol) may be facilitated by specific transport proteins.

it is only found in the plant cells that support the plant which is also made of specialized sugar called cellulose

MAXImum [283]

The cell wall contains not only cellulose and protein, but other polysaccharides as well. The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.
