You are talking with a classmate about modeling electromagnetic waves. You suggest using a spring toy, such as a Slinkie. Your c

lassmate says springs only have compression waves, so your model won’t work. Is your classmate correct?

Answer:Use a stretched Slinky to model sound waves moving through a material.When you squeeze the Slinky's coils together at one end (compression), this causes the coils in front of them to spread out (expansion). When the squeezed coils are released they spread out and squeeze the coils in front of them together. The squeezed coils in turn move forward, pushing on the coils in front of them and so on.

Squeezing the end coils gave them energy that was transferred from one end of the slinky to the other. As the energy goes through the Slinky, all the coils do not move at once, some of the coils are crowded together and some are spread apart.

Answer:

Change of one form of energy into other can occur according to the law of conservation of energy.

Explanation:

According to the law of conservation of energy, energy can not be created or destroyed. However, one energy form can be transformed into another form. These energy transformations also occur in ecosystems.  

In the given example, the solar energy from the Sun was used by seagrass to perform the process of photosynthesis.

During the process, the energy from sunlight was converted into the chemical energy of organic nutrients (glucose). Part of these nutrients is used by seagrass as an energy source while rest is stored in its tissues. The transformation of radiant energy from the Sun into the chemical energy of nutrients present in seagrass follows the law of conversation of energy.

Lerok [7]
I believe that all the above are ethical concerns regarding genetic engineering. Ethics is the study of moral or socially acceptable behavior. With the advent of genetic engineering and the ability to modify the genome of various organs, many ethical questions arise concerning the various scenarios and possibilities. There are many ethical concerns regarding genetic engineering in plants, animals, and humans. One of the ethical concerns regarding genetically modified plants used for food is whether the nutritional value will be sacrificed in favor of a higher yield or drought resistantancy.

PLEASE HELP! Describe what you know about enzymes that explains your evidence and your claim.
grigory [225]

Answer:

In the case of catalase, the optimum pH is approximately pH 7.0. That is, catalase works best at a neutral pH. If the solution is too acidic (low pH value) or too basic (high pH value) the catalase is inactive and no longer functions as an enzyme.

hope this helps!!:)

All of the following are classified as abiotic factors EXCEPT
ella [17]

Answer:

In the group of terms, the exception to abiotic factors is bacteria (option b).

Explanation:

Abiotic factors correspond to the elements of an ecosystem that are not considered alive, such as soil, wind, temperature, pH, among others.

All living beings in an ecosystem are biotic elements, including microorganisms such as bacteria. The dynamics of living beings influence the ecosystem, just as abiotic factors influence both the biotic elements and the development of the ecosystem.

Describe the process of building a paradigm and of shifting one
frutty [35]

Answer:

Explanation:

A paradigm shift is a major change in the concepts and practices of how something works or is accomplished.

A paradigm shift very often happens when new technology is introduced that radically alters the production process of a good or service.

Although the idea of paradigms has been around for quite some time, the concept was explored by physicist and philosopher Thomas Kahn Kuhn.
