Please help me i am stuggaling so badly acellus what is the energy of an orange lamp with a frequency of 5.10 x 10^14 hz ? x 10^? <----- answer like than please
5.88235.10-7 is the energy of an orange lamp with a frequency of 5.10 x 10^14 hz.
What is frequency ?The number of times a repeated event occurs in a given amount of time is known as its frequency. It is also sometimes called "temporal frequency" to stress the contrast to "spatial frequency" and "ordinary frequency" to underline the contrast to "angular frequency." Hertz (Hz), which is equal to one (event) per second, are the units used to express frequency.
The reciprocal of frequency, the period is the length of time occupied by one cycle in a repeating event. The period, T—the space between beats—of a heart beating at a frequency of 120 beats per minute (2 hertz), for instance, is half a second (60 seconds divided by 120 beats). Science and engineering employ frequency as a key characteristic to define the temporal scale.

D. organize the ecosystem.
The main function of detritivores/decomposers/detritus feeders is to: B. release and return matter back to the ecosystem.
What are detritivores?The detritivores are decomposers that will obtain their food from the detritus of the organic matter that is decomposing. This makes them an important part of the ecosystem since they will contribute to the return of nutrients that cannot be decomposed by other organisms.
There are organisms in the ecosystem such as bacteria or fungi that are not able to digest certain types of bits left over from the decomposition of organic materials that other larger detritivores can, but they can absorb butrients at the molecular level.
Within the detritivores we find millipedes, carrion flies, earthworms, some types of beetles, among others.

Explanation:
in addition to burning fossil fuels, humans return co2 to the atmosphere faster than it can be removed by: expanding rice production. generating nutrient pollution. expanding beef production. clearing forests for agriculture. polluting the oceans.
Humans not only use fossil fuels but also cut forests for agriculture, which releases more CO2 into the atmosphere than it can be taken out.
Fossil fuels being burned:
Oil, natural gas, and coal are examples of fossil fuels that are burned to provide energy. We use this energy to create electricity, as well as to fuel industrial activities and forms of transportation (such vehicles and airplanes).
The burning of fossil fuels has various effects on the Earth system. Some of these possibilities are:
The greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) are released into the atmosphere, increasing the greenhouse effect (the reflection of heat back into the atmosphere) and increasing the average global temperature. These greenhouse gases can remain in the atmosphere for decades to hundreds of years.
Fossil fuels form over millions of years from the burial of photosynthetic organisms, including terrestrial plants (which primarily form coal) and marine plankton (which primarily form oil and natural gas).
To grow, these organisms removed carbon dioxide from the atmosphere and oceans, and their burial inhibited the movement of that carbon through the carbon cycle. Burning this fossil material releases this carbon into the atmosphere as carbon dioxide. Its speed is hundreds to thousands of times faster than burial and much faster than the carbon cycle can remove it.
Thus, the carbon dioxide released when burning fossil fuels accumulates in the atmosphere and some of it dissolves in the ocean, causing ocean acidification.

question chitinase is an enzyme that breaks down the chitin molecules in the insect exoskeleton. the sequence of amino acids in the chitinase is an example of which level of protein structure? secondary secondary, tertiary tertiary primary primary quaternary quaternary
Chitinase is an enzyme that breaks down the chitin molecules in the insect exoskeleton. The sequence of amino acids in the chitinase is an example of which level of protein structure is primary.
Chitinases are a common component of all living things and can be found in archaea, bacteria, fungi, plants, and animals. Chitin, the second-most prevalent carbohydrate in nature after cellulose, is broken down by them. As a result, they are crucial for preserving a balance between the carbon and nitrogen that are locked in biomass as insoluble chitin. 18 and 19 glycoside hydrolases are the two families into which chitinases are divided. Many members of the family 18 of chitinases possess a second module, called the chitinase insertion domain, in addition to the catalytic domain, which is a triosephosphate isomerase barrel. The biological significance of the catalytic domain in chitinase activity is the subject of several investigations, although the role of the chitinase insertion domain is still poorly known.To learn more about Chitinase.

With a short time remaining in the day, a delivery driver has time to make deliveries at locations among the locations remaining. How many different routes are possible?.
84 different routes are possible for a delivery driver to make deliveries at locations within the outstanding locations.
The notion of combination in this question provides us with a number of alternative methods to organize a selection from a set. It is most commonly employed in probability. The formula for combination is given by:
(nCr)= n!/(n-r)!r!
To figure out how many paths are conceivable, we must first figure out what is available. Because there are only nine remaining places, we use n = 9. We can only accept 6 places; thus we use r = 6. We utilize combination to determine the number of possible routes that the delivery driver might take. (9C6)

Dependent variable: life of bugs that depends on the independent variable, which here is the the viral infection.Constant: age, size and gender of bugs have been kept same in every chamber.Control group: group 2 and 4 act as a control group.

Humans also use unevenly distributed resources; less than 20% use over 80% of the energy and over half of all renewable freshwater sources making option 2 the correct answer.
Why are humans currently doing these things?
Humans currently are found to be unevenly distributed due to some factors such as climatic factors, economic factors, political factors, geographical factors, and so on. These factors differ across the world and thereby causing uneven distribution of humans and the factors are either getting better or worse in some parts of the world causing an increase in the differences.The human population is increasing rapidly with the increase in activities like agriculture, raising shelters, and economic expansions, as driven humans to almost half of the Earth's land.Resources are not evenly distributed throughout the world as climate differs and this difference is increasing due to humans concentrating more in areas where the resources are available in abundance. The majority of the population doesn't have access to energy resources.There is a big dependence on water by humans and freshwater resources are overexploited even when we have less than 3% of the world's water is fresh. Freshwater is a renewable resource from sources like lakes, rivers, reservoirs, and underground sources.In summary, the human population is increasing rapidly across the world resulting in using unevenly distributed resources, using over half of all renewable freshwater sources, and using almost half of the Earth's land.
