PLEASE HELP!! Phytoplankton are one of the most important parts of the food web in the Hudson river. what evidence supports the conclusion? A) The population of phytoplankton dropped sharply soon after zebra mussels invaded the river. B) The decrease in phytoplankton caused a decrease in the river's zooplankton, fish, and native mussel populations. C) The decrease in phytoplankton meant that the river's turbidity, or cloudiness decreased. D) Zebra mussels caused oxygen levels in the river to drop, partly by removing the phytoplankton that produce oxygen.

Answers

Answer:

Your answer is b

Explanation:

the answer is b because if there is no phytoplankton then there will be no fish and if you take out one part of the food chain then the whole chain comes apart. So meaning if there is no phytoplankton, then there is no fish, if there isn't any fish, then the other animals that come to eat at the river will eventually starve to death or move somewhere else to get more food.

The statement that supports the fact that phytoplankton are one of the most important parts of the food web in the Hudson river is; "the decrease in phytoplankton caused a decrease in the river's zooplankton, fish, and native mussel populations."

Phytoplankton refers to the microscopic and photosynthetic organisms found in water bodies. They are able to trap energy directly from the sun to produce their own food by photosynthesis.

If this primary productivity is hampered in the food web in the Hudson river, there will be nothing for the small fishes to and other native populations to eat and their population will begin to decrease.

Explain how the amount of pressure created by a smaller piston can be the same as the pressure created by a larger piston?

Answers

Answer:

The larger piston will travel a smaller distance but it will exert a larger force. The formula can be rearranged: P=F x A. Because the pressure (P) is the same in the whole system (which is the hydraulic jack), the force (F) will be larger where the area (A) of the piston is larger!

The relation between pressure, force and area shows that pressure is inversely proportional to the area while directly proportional to the force.

What is pressure?

The force was applied perpendicular to an object's surface per unit area across which that force is spread is known as pressure. The pressure gauge in relation to the higher pressures is known as gauge pressure. Pressure is measured in a variety of ways.

Although the larger piston travels a shorter distance, it exerts a greater force. It's possible to rearrange the formula

P=F / A.

where, the pressure (P) in the entire system is the same, the force (F) will be greater where the piston's area (A) is greater.

Therefore, it can be seen that pressure is inversely proportional to the area while directly proportional to the force.

When two or more atoms bond together it is called what?

Answers

Answer:

Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. Chemical reactions occur when two or more atoms bond together to form molecules or when bonded atoms are broken apart.

Explanation:

When two or more atoms bond together it is called a molecule.

Explanation:

When two or more atoms are bonded together they form a molecule.If the atoms bonded together are of the same element then it is said to be the molecule of that element.

For example, sulfur has a molecule of S_8 under normal conditions

If the atoms bonded together are of the different elements then it is said to be the molecule of that specific compound.

For example, ammonia is a compound made up of nitrogen and hydrogen, its molecule consists of one nitrogen atom bonded to three hydrogen atoms, NH_3.

So, we can conclude that when two or more atoms bond together it is called a molecule.

What is greatest velocity? How do you get greatest velocity?

Answers

Answer:

Maximum velocity is reached when you stop accelerating, because this is when you can't gain anymore speed, i.e. acceleration is zero. In other words the derivative of velocity is equal to zero. However, zero acceleration can also result in minimum velocity because you can't lose any more speed.

Explanation:

hope this helps

Velocity is equivalent to a specification of an object’s speed and direction of motion (e.g. 60 km/h to the north). How to get is, Choose a point to the left of the extremum and another point just to the right. If acceleration is negative to the left and positive to the right, the point is a minimum velocity. If acceleration is positive to the left and negative to the right, the point is a maximum velocity. There you go.

I get it! Now I know that atomic theory changed with time because...?

Answers

Answer:

Because more experiments gave more data, theories and models for atoms changed to be more accurate over time. Scientists discovered the small pieces of atoms (electrons-negatively charged and protons-positively charged) and changed their ideas of how they were put together.

Explanation:

The atomic theory changed with time because each scientist went behind another scientist and added on to their ideas and their theories. The models and everything changed as new things about the atom were being discovered. For example, some scientists saw that electrons did not have a specific placement in an atom and instead, it moves around freely in the electron cloud which changed the atomic model later on.

Please write Phython Code according the instructions.Project 2Project 2: Rock, Paper, ScissorsAssignment OverviewThe purpose of this project is to familiarize you with the use of Boolean logic, branching statements and loops. For this assignment, you will create a program that plays the game "Rock, Paper, Scissors."BackgroundRock, Paper, Scissors (also known by several other names, see http://en.wikipedia.org/wiki/Rock_paper_scissors) is an extremely popular hand game most often played by children. Often, it is used as a method of selection similar to flipping a coin or throwing dice to randomly select a person for some purpose. Of course, this game is not truly random since a skilled player can often recognize and exploit the non-random behavior of an opponent; for instance, if you notice that your opponent chooses Paper most frequently, you may choose Scissors (which beats Paper) most often in an effort to win.Rules of the Game:The objective of Rock, Paper, and Scissors is to defeat your opponent by selecting a weapon that defeats their choice under the following rules:Rock smashes (or blunts) Scissors, so Rock winsScissors cut Paper, so Scissors winPaper covers Rock, so Paper winsIf players choose the same weapon, neither win and the game is played againProgram SpecificationsThis project requires you to use:input to prompt the userprint to print resultsat least one branching mechanism (if statement)at least one loop (while loop)Boolean logicYour program will allow a human user to play Rock, Paper, Scissors with the computer. Each round of the game will have the following structure:The program will choose a weapon (Rock, Paper, Scissors), but its choice will not be displayed until later so the user doesn't see it.The program will announce the beginning of the round and ask the user for his/her weapon choiceThe two weapons will be compared to determine the winner (or a tie) and the results will be displayed by the programThe next round will begin, and the game will continue until the user chooses to quitThe computer will keep score and print the score when the game endsThe computer should select the weapon most likely to beat the user, based on the user's previous choice of weapons. For instance, if the user has selected Paper 3 times but Rock and Scissors only 1 time each, the computer should choose Scissors as the weapon most likely to beat Paper, which is the user's most frequent choice so far. To accomplish this, your program must keep track of how often the user chooses each weapon. Note that you do not need to remember the order in which the weapons were used. Instead, you simply need to keep a count of how many times the user has selected each weapon (Rock, Paper or Scissors). Your program should then use this playing history (the count of how often each weapon has been selected by the user) to determine if the user currently has a preferred weapon; if so, the computer should select the weapon most likely to beat the user's preferred weapon. During rounds when the user does not have a single preferred weapon, the computer may select any weapon. For instance, if the user has selected Rock and Paper 3 times each and Scissors only 1 time, or if the user has selected each of the weapons an equal number of times, then there is no single weapon that has been used most frequently by the user; in this case the computer may select any of the weapons.At the beginning of the game, the user should be prompted for his/her input. The valid choices for input are:R or r (Rock)P or p (Paper)S or s (Scissors)Q or q (Quit)At the beginning of each round your program should ask the user for an input. If the user inputs something other than r, R, p, P, s, S, q or Q, the program should detect the invalid entry and ask the user to make another choice.Your program should remember the game history (whether the user wins, the computer wins, or the round is tied).At the end of the game (when the user chooses 'q' or 'Q'), your program should display the following:The number of rounds the computer has wonThe number of rounds the user has wonThe number of rounds that ended in a tieThe number of times the user selected each weapon (Rock, Paper, Scissors) What is the missing value?
