Why was the lion fish able to go from a very small initial population on the coast of Florida to taking over the Atlantic coast and Bahamas
Answers
Answer and Explanation:
Due to the lionfish not having any known predators in this region, it was able to reproduce with ease and no worry of any attackers, so nothing to keep the animal in check.
Because of this, the animal became an invasive species, and the people are trying their best to get rid of the species here by allowing anyone to catch it (with a permit/license as so non-permit people don't harm themselves) at anytime of year.

A 10kg mass is lifted to a height of 2m. What is its potential energy at this position?
Answers
Answer:
m=10kg h=2m Ep=mgh Ep=(10kg)(9.8 m/sec2)(2m) Ep=196J
Explanation:
The formula for potential energy depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

Answers
Answer: Adaptation
Explanation:
9. Most agricultural fields receive inputs of phosphorus, calcium, and magnesium, which are usually obtained by mining rocks containing those elements, grinding them up, and adding them
to fertilizers. Assess the likely impact of this practice on the demand for certain rocks and on soil dynamics with regards to both a) a nutrient cycle and b) a feedback loop.
Answers
This practice has a great impact on the demand of certain rocks.
There is great impact of this practice on the demand for certain rocks because they are necessary for the higher productivity of crops so their demand as well as price of that rock increases. This practice of adding of nutrients has good effects on soil dynamics as well as on nutrient cycle because these nutrients are not only use by the plants as well as by soil in order to maintain its structure.
A feedback loop is the part of a system in which some portion of the system's output is used as input for future operations. In this situation, the feedback loop is negative because all the materials are used from outside and the output can't be used in the system so we can conclude that this practice has a great impact on the demand of certain rocks.

What are some things water will adhere to? and What are some things water will not adhere to?
Answers
Answer:
1. Water has an amazing ability to adhere (stick) to itself and to other substances. Hydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH3), water (H2O) and hydrogen fluoride gas (HF).
2. In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Answers
Answer:
Organ 1: Stomach
Explanation:
The stomach holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a useable form. The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The large intestines are to absorb water and salts from the material that has not been digested as food and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption have already taken place. The small intestines have three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body. The small intestine is part of the digestive system.
