ASAP HELP 100 POINTS + BRAINLEY 2. Write 1–2 paragraphs that summarize how spectroscopy provides information about the composition of objects. Use data from the lab to support claims you make, and provide compelling reasoning. Make an effort touse proper writing conventions in your summary (such as good punctuation, spelling, and capitalization)
Answer:
Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. Simply, spectroscopy is the study of color as generalized from visible light to all bands of the electromagnetic spectrum; historically, spectroscopy originated as the study of the wavelength dependence of the absorption by the gas phase matter of visible light dispersed by a prism. Matter waves and acoustic waves can also be considered forms of radiative energy, recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory as well. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of physics, chemistry, and astronomy, allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances.
The spectrum is determined by measuring changes in the intensity or frequency of this energy. The types of radiative energy studied include: Electromagnetic radiation was the first source of energy used for spectroscopic studies. Techniques that employ electromagnetic radiation are typically classified by the wavelength region of the spectrum and include microwave, terahertz, infrared, near-infrared, ultraviolet-visible, x-ray, and gamma spectroscopy. Dynamic mechanical analysis can be employed to radiating energy, similar to acoustic waves, to solid materials. The types of spectroscopy also can be distinguished by the nature of the interaction between the energy and the material example:Absorption- when energy from the radiative source is absorbed by the material. Elastic scattering and reflection spectroscopy determine how incident radiation is reflected or scattered by a material. Crystallography employs the scattering of high energy radiation, to examine the arrangement of atoms in proteins and solid crystals. Coherent or resonance spectroscopy are techniques where the radiative energy couples two quantum states of the material in a coherent interaction that is sustained by a radiating field. Spectroscopic studies are designed so that the radiant energy interacts with specific types of matter.

vertebrate
eukaryotic
The characteristic that all protozoans display is their eukaryotic nature. Thus, the correct option for this question is D.
What do you mean by Protozoans?Protozoans may be defined as single-celled microscopic organisms that significantly belong to the kingdom of Protista. These organisms are eukaryotic in nature, and hence they have a true and membrane-bound nucleus in order to function properly.
Some protozoans are definitely attached to the substrate or construct cysts. So, they do not migrate around. But some protozoans have the capability to move around at some stages in their life cycles mostly after the cell division.
So, option B is eliminated. Protozoans are heterotrophic as well. They use organic carbon as a source of energy. So, option A is eliminated.
Therefore, the characteristic that all protozoans display is their eukaryotic nature. Thus, the correct option for this question is D.

Explanation:
electromagnetic waves: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.
radio waves: Radio waves are a type of electromagnetic radiation best-known for their use in communication technologies, such as television, mobile phones and radios. These devices receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves.
microwaves: Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively.
infrared: Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark.
visible ray: The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers
ultraviolet:UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning. Different UV wavelengths and intensities are used for different purposes
xray:An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (30×1015 Hz to 30×1018 Hz)
gama ray :A gamma ray, also known as gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei.
Most of the reactions by which energy from carbohydrates is released for use by the cell take place within the?
Answer:
Explanation:
The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP. Some of the energy released is lost as heat.
The release of energy from carbohydrates takes place within the
mitochondria.
The mitochondria is an organelle found within cells and it is regarded as
the power house of the cell. This is because energy is generated in it which
gives the cells power to perform its daily activities.
Energy generated from carbohydrate is usually in the form of ATP and it
involves series of reactions such as glycolysis, kreb cycle etc to ensure
adequate energy yield.

6. Identify the type of climate data that has the longest data range. 1. microscopic organism 2. data sediment core 3. data tree ring 4. data ice core data
Complementing data, taken from different sources such as tree rings, sediments, and ice, provides significant information about global climatic changes. However, ice core data has the longest data range. (4) is correct.
-------------------------------
Ice core data refers to the information obtained from a sample of ice taken from a glacier or a mountain.
Information kept in the ice is mostly about gases concentration at different moments though time.
Analysis of retained gases in Antarctic ice, through perforations of over 2000 meters deep, has allowed knowing the CO₂ atmospheric concentrations and other gases involved in the greenhouse effect for at least 150,000 years.
These concentrations have varied in the temporal scale of glaciation, showing low concentrations during glacial periods with low temperature and relatively high concentrations during interglacial periods with high temperature.
Between these two periods, abrupt variations in temperature and gas concentration are detected, meaning that changes in CO₂ cause changes in temperature.
The increase in CO₂ is a highly significant component in global climatic change and possibly the best documented.
This information is the best paleoclimatic documents.
Complementing it with marine sediments core and data tree rings makes it possible to know about the principal traits of terrestrial weather in the lasts 420,000 years, practically four glacial-interglacial cycles.

Explain how fitness can change the allele frequency of a population. PLZ no link
Answer:
Natural selection can cause microevolution (change in allele frequencies).
Explanation:
With fitness-increasing alleles becoming more common in the population.
Fitness can affect the survival and reproduction rates of individuals with different alleles, leading to differential contribution to the next generation and changes in the frequency of these alleles in the population.
What is fitness?Fitness is a measure of the reproductive success of an individual within a population. The fittest individuals are those that are most successful at passing their genes on to the next generation. When the environment changes, the selective pressures on a population also change. This can lead to changes in the relative fitness of different individuals, and thus changes in the allele frequencies of a population over time.
For example, if a population of birds lives on an island with small seeds, those birds with small beaks may be more fit than those with larger beaks. This is because they are better adapted to the environment and can more easily obtain food. Over time, the frequency of the small-beaked allele will increase in the population, while the frequency of the large-beaked allele will decrease.
Thus, fitness can drive changes in the allele frequency of a population over time by favoring those individuals with alleles that are better adapted to the environment.
