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.

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.

What is data analysis?

Although several groups, organizations, and specialists approach data analysis in various ways, most of them may be boiled down into a general description. Data analysis is the method of modifying, processing, and cleansing raw data in order to obtain useful, pertinent information that supports commercial decision-making.

Every time we make a choice in our daily lives, we may observe a basic example of data analysis by assessing what has happened previously or what might happen if we take that action. In essence, this process is looking at the past and future then making decisions in light of that analysis. Graphs are created during data analysis.

SMART PEOPLE ONLY Explain the Solar Eclipse in 4-5 sentences (BRAINLIEST)

Answers

Answer: Hope this is smart enough.

A solar eclipse occurs when a portion of the Earth is engulfed in a shadow cast by the Moon which fully or partially blocks sunlight. This occurs when the Sun, Moon and Earth are aligned. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured. An eclipse is a natural phenomenon. However, in some ancient and modern cultures, solar eclipses were attributed to supernatural causes or regarded as bad omens. A total solar eclipse can be frightening to people who are unaware of its astronomical explanation, as the Sun seems to disappear during the day and the sky darkens in a matter of minutes.

Explanation:

Answer:

A solar eclipse occurs when a part of the earth in engulfed in a shadow cast by the Moon which fully or partially blocks sunlight. The Moon's shadow is not big enough to engulf the entire planet, so the shadow is always limited to a certain area. Solar eclipses are only visible from within the area on Earth where the Moon's shadow falls, and the closer you are to the center of the shadow's path, the bigger the eclipse looks.  Solar eclipses are usually named for their darkest, or maximum, point. The exception is the hybrid eclipse.

1. How did Mosely contribute to the periodic table arrangement?

Answers

Answer:

1. Mosely arranged the elements based on the increasing number of protons, atomic number.

2. According to Moseley, similar properties recur periodically when elements are arranged according to increasing atomic number. Atomic numbers, not weights, determine the factor of chemical properties. Mendeleev ordered his elements in order of their relative atomic mass, and this gave him some problems.

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.

Extending the light rail is expected to provide several benefits including reduced traffic, cleaner air, and better access to transit for low-income populations. But, the project will involve considerable noise and traffic delays due to construction. Improving the composting program would help reduce the city's waste stream and also lead to emissions reductions.
