Answer:
The missouri River is a Longesr tributary of the Mississippi River.
The Missouri River is tributary of the Mississippi River.
What is the Missouri River?The Missouri River is known as the longest river in the United States. Missouri flows east and south for 2,341 miles before mixing with the Mississippi River north of St Louis, Missouri.
The river drains include parts of ten U.S. states and two Canadian provinces although a tributary of the Mississippi, the Missouri River is marginally longer and has a comparable volume of water. When combined with the lower Mississippi River, it creates the world's fourth-longest river system.
People depend on the Missouri River and its tributaries as a source of transportation and sustenance. The Missouri River was the main route for the westward expansion of the U.S. during the 19th century.
During the 20th century, the Missouri River was developed for irrigation, flood control, and the generation of hydroelectric power. Fifteen dams formed the stem of the river, with hundreds more on tributaries.

How are rocks formed? Explaine in 500 words or less.
Explanation:
Rocks are formed from aggregates of minerals. There are three different types of rocks and they are formed by different processes. Igneous rocks are formed by the cooling and solidification of magma within or on the earth crust. Sedimentary rocks are formed from pre-existing rocks by the lithification of sediments brought into a basin of deposition. Metamorphic rocks are changed rocks that have been mineralogically altered.
Different rocks form under specific conditions and environment. But rocks are connected to one another through the rock cycle. The rock cycle shows that rocks can transition from one form to another.help will make brainliest! :)

What are the four functions of cell division?
Answer:
Cellular division has three main functions: (1) the reproduction of an entire unicellular organism, (2) the growth and repair of tissues in multicellular animals, and (3) the formation of gametes (eggs and sperm) for sexual reproduction in multicellular animals.
Answer:
There are four key reasons why a cell may be required to divide mitotically:
Tissue repair / replacement.
Organismal growth.
Asexual reproduction.
Development (of embryos)

Explanation:
For an ideal gas, which two variables are directly proportional to each other (if all other
conditions remain constant)?
1. T and n
2. V and n
3. V and T
Answer:
3. V and T
Explanation:
For an ideal gas the volume and temperature remains directly proportional even if other conditions are constant.
This is the premise of the Charles's law.
Charles's law propounded by Jacques Charles found the relationship between the volume and temperature under constant pressure and predicted the absolute scale of temperature.
His law states that;
"The volume of a fixed mass (mole) of a gas varies directly as its absolute temperature if the pressure is constant".
So;
V ∝ T (P, n constant)
Order the following atoms from smallest to largest atomic radius: C, N, P
Answer:
N ∠ C ∠ P
Explanation:
Atomic radius:
It is define as the distance from nucleus of an atom the outer most electronic shell.
As we move down the group atomic radii increased because of increase of atomic number. Electrons are added in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
When we move from left to right across the periodic table electron are added in the same shell at the same time protons are also added in the nucleus hence positive charge is going to increase and this effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus and atomic radii decreases.
Carbon and nitrogen are present in period 2 while phosphorus is present in period 3 thus phosphorus has largest atomic radii. Carbon and nitrogen are present in same period but nitrogen is more right as compared to the carbon which means nitrogen has one more valence electron thus its size is smaller than carbon.
Values of atomic radii.
P = 98pm
C = 67pm
N = 65 pm
N ∠ C ∠ P

the entropy of the system
(1) decreases and heat is absorbed
(2) decreases and heat is released
(3) increases and heat is absorbed
(4) increases and heat is released
The entropy of the system increases and heat is absorbed in this chemical reaction.
What happen when NH4Cl reacts with water?When ammonium chloride NH4Cl reacts with water, it absorb energy for the surrounding and decomposes into its component ions such as NH4+ and Cl- so we can conclude that increases occur in the entropy of the system and heat is absorbed.

. A skydiver jumps from an airplane and opens his parachute. At some point during his fall, the downward force of gravity on the skydiver is equal to the upward force of drag on the parachute. Which of the following best describes the skydiver's motion at this point? The skydiver is gaining speed downward. The skydiver is moving at a constant speed. The skydiver is decreasing in speed.
The upward drag and downward force is equal for the skydiver when he jumps down from the plane. Thus, he experiences a constant speed through out his motion.
What is gravitational force?Gravitational force is a kind of force by which a body attracts other objects into its center of mass. Force exerted by the body depends on the mass and distance to it.
Earth pull every objects into its surface by gravitational fore of attraction. For moving body the the gravitational force acting downward have an acceleration due to gravity.
The skydiver experiences a force upward by the drag of a the parachute. When this force becomes equal to the downward fore of gravity, then his speed will be constant thus, no gain or lose for speed.

How is a carbon atom different from a hydrogen atom?
Answer:
Carbon atom is a chemical element with the symbol C and atomic number 6 ( electrons). While Hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron.
Explanation:
The carbon atom different from a hydrogen atom, because the atomic number of hydrogen is 1 . The atomic mass number of hydrogen is also one. For the carbon atom, the atomic number is 6, and the atomic mass number of carbon is 12.
What is an atomic number ?The term atomic number is defined as the number of a chemical element in the periodic system. The elements are arranged in order of increasing number of protons in the nucleus.
The atomic number is situated at the upper left, or number of protons. In the middle is the letter symbol for the element. Atomic number is equal to the proton number or the number of protons found in the nucleus of every atom of that element.
Thus, Carbon atom is a chemical element with the symbol C and atomic number 6. Whereas hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron and its symbol is H.
