Of the three waves shown, Wave 2 has the greatest
wave speed, because it has more crests than the other ropes
O frequency because it has a large wavelength than the other ropes
wave speed because the rope is moving up and down faster than the other ropes
frequency, because there are more crests in the same length of rope than there are in the other waves
Answers
Answer:
D. frequency, because there are more crests in the same length of rope than there are in the other waves
Explanation:
Wave frequency is defined as the number of waves passing a fixed point at a given time.
Wave frequency is highly influenced by the number of crests in the wave that pass the fixed point in 1 second. It means, more is the number of crests in the same length of rope, the higher will be the wave frequency.
Wave 2 has a maximum number of crests and thus wave 2 has the greatest wave frequency in comparison to other ropes.
Hence, the correct answer is "D".

Which of these chemicals is not a pollutant?
A. Methane
B. Nitrogen gas
C. Nitrate
D. Carbon dioxide
Answers
Answer:
All these chemicals are primary causes of pollution. Although, only one isn't an air pollutant. Which would make my best Guess C. Nitrate
Explanation:
A. Methane Is the main component in gas and oil. Oil companies have been responsible for polluting our air with about seven million tons of methane per year.
B. Nitrogen gas in general is one of the main air pollutions. otherwise know as Nitrogen dioxide.
C. Nitrates are found in ground waters and transfers into the soils surrounding said waters. Nitrates commonly are a cause of death in infants when drinking tab water or eating crops grown from nitrate infected soils. Adults aren't nearly as infected by this.
D. Carbon Dioxide is a greenhouse gas that pollutes our air and has been a main cause of global warming.
I'm at a loss for answering this question since all of these are polluting our earth in some way. The only way I can think to answer this is that all but one are air pollutants. So maybe the one that is not a air pollutant is the correct answer. My best guess is C. Nitrate

Why does evolutionary theory absolutely require the earth to be very
old?
Answers
Answer:
Mainly because Evolution takes millions and millions of years to happen.
Explanation:
Evolutionary theory require earth to be very old because the process of evolution takes millions of year to happen.
What do you mean by evolution ?Evolution is the process through which a population of organisms evolves as new generations replace ancestors. Individual species do not evolve; rather, communities of organisms do.
Natural selection processes like as environmental change, predation, or human disturbance create evolutionary adaptations, and these processes must continue and grow widespread for the change to remain and accumulate. That happens less frequently and slowly than you may expect.
Scientists have determined that Earth is 4.54 billion years old, with a 50 million year error, by dating the rocks in its ever-changing crust as well as those in Earth's neighbors, including the moon and passing meteorites.
Therefore, the Earth needs to be very old for evolutionary theory to be true.

d. ribosomes
Answers
During cell reproduction, chromatin fibers coil up into structures called chromosomes. Therefore, the correct option is A.
What are chromosomes?Chromosomes are structures made up of DNA and proteins that are found in the nucleus of the cell. They contain genetic information That are responsible for the inherited characteristics of the organisms such as eye color, hair color, height etc.
Chromosomes play a crucial role in cell division, as they ensure the proper distribution of genetic material to the daughter cells.
During cell division, chromosomes are replicated and then separated into daughter cells, ensuring that each cell receives a complete set of chromosome.
The number and arrangement of a chromosome vary depending on the species, but all human cells except the sperm and egg cell contains 23 pairs of chromosomes. Hence, the correct option is A.

Every single cell of an organism is able to survive independently because it carries out metabolic processes at its own.
What is Metabolism?Metabolism can be defined as the chemical changes or reactions which take place in a cell or an organism. These changes make energy and the compounds which cells and organisms need to grow, reproduce, and stay healthy.
Metabolism is divided into two classes: anabolism and catabolism. Anabolism involves the synthesis of a complex compound from simpler or smaller molecules or atoms. Catabolism involves the breakdown of a complex molecule into smaller and simpler ones.
Living organisms are able to perform the metabolic processes such as respiration, excretion, reproduction, and digestion which is a distinguishing factor from that of non-living organisms.

Off the coast of the Pacific Northwest in the United States, the Pacific plate is being pushed underneath the North American plate in a subduction zone, caused by plate tectonics. As the rock from the Pacific plate is pushed under the North American plate, it is subjected to high temperatures and pressures. Which rock will be created from this process?
Answers
Answer:
Metamorphic rocks
Explanation:
When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma. In the western Pacific crust is old and thick, and hence it submerges easier in the mantle.
Metamorphism provokes structural and mineralogic reordering in an original preexisting rock, under the influence of factors such as temperature and pressure, which are two of the most important and influencing ones.
This physic-chemical processes usually occur in deepness, many times related to plates movement and subduction processes. The sharped temperature rising might be caused by magma injection or by a deep placement or the original rock in a subduction zone.
According to the metamorphism processes, there are different kinds of metamorphic rocks. Metamorphic rocks that are the product of subduction event, belong to "regional metamorphism" which includes a huge area, and among this classification, "underground metamorphism" is associated with plates subduction, with a range temperature among 400-600ºC.

Diffusion is the movement of molecules from an area of high concentration of molecules to an area with a ____ concentration.
A. Equal
B. Higher
C. Lower
D. None of the above
Answers
Answer:
lower
Explanation:
Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. So, the correct option is C.
What is diffusion?Diffusion is a type of passive transport, this means that it does not require any kind of external energy for movement of molecules. The difference in concentration in two areas gives rise to a concentration gradient. Where, in one area there is high concentration of molecules and in another, there is low concentration of molecules.
If the molecules move from an area of higher concentration to an area of lower concentration, they are moving along the direction of concentration gradient. This is why no additional energy is required. Diffusion is a type of passive transport where molecules move along a concentration gradient.
This is in contrast to active transport where molecules move against the concentration gradient and therefore require external energy.
Therefore the correct option is C.
