Why is a red laser pointer an example of a poor blackbody radiator?
A. It glows less brightly as electromagnetic radiation is released.
O B. It gives off a range of wavelengths of electromagnetic radiation.
C. It gives off only one wavelength of electromagnetic radiation,
D. It keeps the same temperature and gives off no electromagnetic
radiation
Answers
A red laser pointer is a poor blackbody radiator because it emits electromagnetic radiation at only one wavelength. So, the correct option is C.
What is blackbody radiator?Depending on its temperature, a blackbody radiator is an object that radiates at different wavelengths. Blackbody radiation is the radiation that a blackbody radiator emits, and it exhibits a certain pattern known as Planck's law.
A red laser pointer, on the other hand, produces a narrow, focused beam of light at a specific wavelength, typically around 650 nanometers. This indicates that, unlike a blackbody radiator, a laser pointer does not generate radiation at different wavelengths. A red laser pointer is therefore a subpar blackbody radiator.
Therefore, the correct option is C.

Answer this question.
An on-going research study has been tracking the dietary preferences of gorillas in the wild. Researchers are hoping to formulate a diet for gorillas in captivity that mimics those living in their natural habits. By reproducing the preferred diet, researchers hypothesize that the eventual release back into the natural habitat will be an easier transition for the gorillas.
Researchers are using various methods to make observations and collect data about the feeding habits of gorillas in the wild. Which method would be classified as direct observation?
A) Counting and classifying the debris in the area where the gorillas live.
B) Observing the gorillas from a protected location and recording what they eat.
C) Surveying the natives in the area about the diet of the local gorilla population.
D) Photographing the habitat of the gorillas in a before and after scenario and seeing what is missing from the after photograph.

What kind of atoms are in an amino acid?
Answers
Answer:
The term amino acid is short for α-amino [alpha-amino] carboxylic acid. Each molecule contains a central carbon (C) atom, called the α-carbon, to which both an amino and a carboxyl group are attached. The remaining two bonds of the α-carbon atom are generally satisfied by a hydrogen (H) atom and the R group.
Explanation:
what type of carbon sink does the author propose people use?
Answers
Answer: Underground facilities that previously contained fossil fuels
Explanation:
In the attached passage, the author speaks on how natural carbon sinks such as trees and oceans can not be trusted with holding Carbon dioxide indefinitely because oceans are reaching their holding limits and trees are being cut down on a massive scale.
The author suggestion to mitigate this is to convert underground facilities such as oil and gas wells that previously held fossil fuels until they were pumped out. The author claims that the technology to do so is already present and that there are ways this could be made inexpensive.

explain why soil micro-organisms should break down plant and animal residues
Answers
Hello there wish you a GREAT Thanksgiving :)
Microbial Soil Organic Matter Decomposition
Organic matter decomposition serves two functions for the microorganisms, providing energy for growth and suppling carbon for the formation of new cells. ... Dead plant residues and plant nutrients become food for the microbes in the soil.
Microbes thrive underneath no-till conditions and winter cover crops. cowl plants and manure may be used to feed soil microbes and recycle soil vitamins. As soil microbes decompose organic residues, they slowly release vitamins lower back into the soil for the winter cowl vegetation or for the preceding crop.
Why soil microorganisms should break down plant and animal residues?
By-products from growing roots and plant residues feed soil organisms. In turn, soil organisms support plant health as they decompose organic matter, cycle nutrients, enhance soil structure and control the populations of soil organisms, both beneficial and harmful (pests and pathogens) in terms of crop productivity.
What's the significance of microorganisms within the soil what's their role?Useful soil microbes carry out fundamental capabilities which include nutrient cycling, breaking down crop residues, and stimulating plant boom. at the same time as the position of microbes to preserve soil fitness and make contributions to crop performance is clear, the soil organic factor is extremely difficult to take a look at and control.

Explanation:
In 1972, EPA issued a cancellation order for DDT based on its adverse environmental effects, such as those to wildlife, as well as its potential human health risks. Since then, studies have continued, and a relationship between DDT exposure and reproductive effects in humans is suspected, based on studies in animals.
Human health effects from DDT at low environmental doses are unknown. Following exposure to high doses, human symptoms can include vomiting, tremors or shakiness, and seizures. Laboratory animal studies showed effects on the liver and reproduction. DDT is considered a possible human carcinogen.
What happens to the atoms of a solid when the temperature increases?
Answers
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
