Answer:The relationship which is between bacteria and ungulates with the intestine is or good example of mutualism. Mutualism plays an important role in ecology. We can say that if we measure the exact fitness what we get as a benefit is a mutualistic relationship.example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. Oxpeckers land on rhinos or zebras and eat ticks and other parasites that live on their skin. The oxpeckers get food and the beasts get pest control.

What other substance (besides salt) could you sprinkle over ice to affect how fast it melts? Describe how you would test the substance's impact on the melting time of ice. Predict the results of such a test.
Answers
Answer:
See explanation
Explanation:
Salt makes ice to melt faster than it usual. Sugar is another substance that influences the melting time of ice.
If i have a sample of pure ice and another sample of ice treated with sugar. I have to maintain the both initially at 0 degrees temperature and have a stop clock to measure the melting time.
I will ultimately notice that the sample of ice treated with sugar will melt faster than the pure sample of ice due to the presence of an impurity.

what is the relationship between nitrogen and carbon-14?
Answers
Answer:
The relationship between carbon-14 and nitrogen is that carbon-14 forms from nitrogen atoms and eventual decays into atoms of nitrogen-14.
Explanation:
The relationship between carbon-14 and nitrogen is that carbon-14 forms from nitrogen atoms and eventual decays into atoms of nitrogen-14.
Since carbon-14 contains an unstable nucleus that decays radioactively over time, it is a radioactive isotope of carbon. The atomic nucleus of this substance, which goes by the symbol "C-14," consists of six protons and eight neutrons. On Earth, carbon-12 (C-12), an atom with six protons and six neutrons, makes up the vast bulk of the carbon.
In the high atmosphere of the planet, a nuclear process known as cosmic ray spallation produces carbon-14. High-energy cosmic rays hit with nitrogen-14 (N-14) atoms in the atmosphere, with the majority of these collisions coming from the Sun and other space-based sources.

2. Consider the table of boiling points and structural isomers. Note that butane has two possible isomers but that decane has 75 possible isomers. Why does the number of possible isomers go up with an increasing number of carbon atoms?
Answers
Answer:
because the number of constitutional confirmation , and geometric isomers goes up with each carbon atom added there are many more possible configurations and connectivities possible with decane , a 10 carbon chain , than with butane, a 4 carbon chain
"The number of possible isomers go up with an increasing number of carbon atoms because as the number of carbon atoms increases the tendency to form branching with other carbon atom increases as well."
What is isomer?
Isomers are molecules or polyatomic ions that have the same molecular formulas that is, the identical number of atoms of each element but different atomic configurations in space. Isomerism refers to the existence or potential of isomers. Isomers don't have to have the same chemical or physical properties.

How does energy play a role in different rock types forming? I had this question another time in my test and it's asking the same thing again.
Answers
Answer:
Yes
Explanation:
Yes, there are many energy forces that directly affect the formation of rocks and other substances. The Sun itself provides both energies in the form of heat/radiation and magnetic energy. Heat can get so intense when combined with pressure from being so far underground that it causes rocks to melt and become magma, which combines with other minerals and forms new types of rocks when they cool in the future. Magnetic energy helps push and pull the waves and wind on Earth which ultimately break down rocks into sand over the years.

Read this passage about Christopher Reeve.
Christopher Reeve was born on September 25, 1952, in New York City. His mother was a journalist, and his father was a professor. As a kid he played sports, did well in school, and liked acting. His passion for acting goes back to playing with his brother when they were little. Reeve acted in his first play at the age of nine. After attending college, taking acting classes, and acting in many plays and movies, Reeve landed his biggest role. In 1978, he played the title role in Superman. He received very positive reviews for his performance and starred as Superman in all the sequels. Reeve was soon acting as the lead role in dozens of movies after Superman. Once well-known, Reeve used his celebrity status for good causes, such as visiting very sick children through the Make-A-Wish foundation. He was also a track and field coach at the Special Olympics.
Besides acting, Reeve was also a licensed pilot and liked horseback riding. He learned to ride horses for a movie role, and he continued riding in his free time. Unfortunately, while riding one day in 1995, Reeve fell from his horse and became paralyzed from the neck down. Being confined to a wheelchair did not hold back Reeve from being socially active, and after many surgeries and rehabilitation, he decided to dedicate his life to helping people with spinal-cord injuries. He created the Christopher Reeve Foundation, which supports the improvement of the lives of people with disabilities and helps fund research to find a cure for paralysis. He was also politically active, working with senators to make sure that people with disabilities were treated fairly in the workplace. Reeve received many awards for his dedication to public service. He also wrote two books about his experiences, and a documentary was made about his life. Reeve passed away in 2004, but his legacy lives on today. He touched the lives of many people and showed us what it means to overcome extreme odds by never giving up.
Based on this passage, Reeve best fits in the yearbook category

You have learned that the atomic number of a chemical is the number of protons found in the nucleus. Atomic numbers can be used to find the number of neutrons and electrons in an atom. In this project, you will practice atomic mass and atomic mass number calculation as well as fill out a chart using the periodic table. Don’t forget to read through the rubric below, so you will know what you will be graded on. When you are ready, upload it replacing the “Lastname” in the saved document name with your last name.
Part I:
The atomic number of the sodium atom is 11. The atomic mass number can be estimated by rounding the atomic mass to 23. From this information, you can find the number of neutrons: 11 protons plus how many neutrons equals a mass number of 23? The number of neutrons would have to be the difference between 23 and 11, which is 12. This fact can be restated this way: 11 protons plus 12 neutrons equals a mass number of 23. For every proton in the nucleus, an electron revolves around the nucleus. Since 11 protons are in sodium, 11 electrons must be in sodium.
Using this information and the Periodic Table from lesson titled Periodic Table fill in the chart below.

Answer:
Our planet's rotation produces a force on all bodies moving relative to theEarth. ... The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected.
Explanation:
Earth's rotation affect ocean currents because: A. It causes them to flow in a curved path.
What is Earth rotation?Earth rotation can be defined as the amount of time that is taken by planet Earth to complete its spinning movement about an orbital axis.
This ultimately implies that, Earth rotation refers to the time taken by earth to rotate once on its axis. Also, a spinning movement of the Earth on its axis takes approximately 24 hours to complete with respect to the Sun and it result in an effect called Coriolis.
In conclusion, Earth's rotation affect ocean currents because it causes them to flow in a curved path due to Coriolis effect.

Explain the trend in boiling points as you move down group v11
Answers
Answer:
Fluorine

Bromine
Iodine
Boiling point increases as you go down the group v11
Explanation:
The elements of Group VII are the halogens consisting of f fluorine (F), chlorine (Cl), bromine (Br), iodine (I). All of which are non metals and exists as diatomic molecules - F2, Cl2, Br2, I2 with intermolecular attractions between the two molecules of each element held by Van der Waals dispersion force.
Moving down the group, the size of the atoms increases in size from Fluorine, F2 and Chlorine, Cl2 which are gases to Bromine , Br2 which exists as a liquid to solid, Iodine, I2. This attributes to the increasing in Strength of the Van der Waals forces as you go down the group. In order to break the vanderwaals forces , More heat energy is required to change thier states leading to the increase in boiling point going down the group.
