Enzymes are proteins that contains ribonucleic acid (RNA) .An enzyme binds to one or more reactant Molecule in order to catalyze a reaction.

Explanation:

1. Enzymes speed up chemical reactions by lowering the Activation Energy, which allows the reaction to proceed much more quickly.

2. During an enzymatic reaction, a molecule of Substrate binds to the enzyme and is broken down into one or more molecules of  product, which are released.

3. The induced fit between an active site and its substrate often strains bonds and helps the reaction proceed

4. The specific location within an enzyme molecule where the substrate binds is called the Active site.

5. Lactose takes years to break down on its own. But if exposed to the protein lactase, the reaction proceeds very quickly, while lactase itself remains unchanged. Lactase is an example of an enzyme

6. High temperatures or changes in pH can an enzyme, causing it to lose its shape and biological activity. An  inhibitor  is a molecule that can bind to an enzyme and prevent the enzyme from working.

7. An enzyme is considered a Catalyst because it speeds up a chemical reaction without being used up.

Domestic cattle often have interactions with wild animals. In South America,
scZoUnD [109]

Answer:

Bats are the only mammals that can fly, but vampire bats have an even more interesting distinction—they are the only mammals that feed entirely on blood.

Nocturnal Behavior

These notorious bats sleep during the day in total darkness, suspended upside down from the roofs of caves. They typically gather in colonies of about 100 animals, but sometimes live in groups of 1,000 or more. In one year, a 100-bat colony can drink the blood of 25 cows.

During the darkest part of the night, common vampire bats emerge to hunt. Sleeping cattle and horses are their usual victims, but they have been known to feed on people as well. The bats drink their victim's blood for about 30 minutes. They don't remove enough blood to harm their host, but their bites can cause nasty infections and disease.

Hunting for Blood

Vampire bats strike their victims from the ground. They land near their prey and approach it on all fours. The bats have few teeth because of their liquid diet, but those they have are razor sharp. Each bat has a heat sensor on its nose that points it toward a spot where warm blood is flowing just beneath its victim's skin. After putting the bite on an animal, the vampire bat laps up the flowing blood with its tongue. Its saliva prevents the blood from clotting.

Young vampire bats feed not on blood but on milk. They cling tightly to their mothers, even in flight, and consume nothing but her milk for about three months.

The common vampire bat is found in the tropics of Mexico, Central America, and South America.

Can humans live underwater what are some things to consider
timurjin [86]

Underwater living faces many of the same life support challenges as living in space. ... But in the future, underwater habitats might provide their own oxygen with artificial gill technology to extract dissolved air from the sea water

Since humans do not have gills, we cannot extract oxygen from water. Some marine mammals, like whales and dolphins, do live in water, but they don't breathe it. They have developed a mechanism to hold their breath for long periods of time underwater.

To put these depths into perspective, three American football fields laid end to end would measure 900 feet (274.32 m) long — less than the distance these divers reached underwater. Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.
