where are the motor proteins that move chromosomes toward the poles of the mitotic spindle located?
Answer:
They are at or near the ends of the microtubules. I hope this helps you! :D
Microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.
What are motor protein?Motor protein are defined as a group of molecules with the ability to travel across the cytoplasm of animal cells. Molecular motors called motor proteins move along the cytoskeletal filaments of the cell by hydrolyzing ATP. They provide a variety of tasks for biological systems, such as facilitating intracellular trafficking along biopolymer filament tracks and regulating filament sliding during muscle contraction.
Microtubules are defined as the cytoskeleton is made up of tubular-structured polymers, which are present throughout the cytoplasm. Microtubules play a variety of roles in dividing cells, including the construction of the mitotic spindle and axon extension in neurons.
Thus, microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.

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.

Most metabolic and regulatory functions in a neuron happen in the cell body or soma.
Where do most metabolic and regulatory functions occur in a neuron?In a neuron, the cell body or soma is where the majority of metabolic and regulatory functions take place. The cell body contains the nucleus, which houses the genetic material necessary for protein synthesis and other cellular processes.
It also contains various organelles such as mitochondria, responsible for energy production and metabolism. Additionally, the cell body is involved in regulating the neuron's overall function including maintaining its structural integrity and coordinating signals received from dendrites and transmitted through the axon.

Which molecule supplies chlorophyll with electrons
In light reactions, a molecule of chlorophyll absorbs one photon of light, causing a chlorophyll electron to transfer to a higher energy level. The energized electrons from the chlorophyll molecules flow down a transportation chain to a compound called nicotinamide adenine dinucleotide phosphate or NADP.
▪▪▪Cutest Ghost▪▪▪Water is the molecule that supplies chlorophyll with electrons.
What happens during photosynthesis?Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose (sugar) and other carbohydrates. This process also produces oxygen as a byproduct.
During the process of photosynthesis, chlorophyll absorbs light energy, which is used to split water molecules into oxygen and hydrogen atoms. The hydrogen atoms are then used to generate ATP and NADPH, which are used to power the process of carbon fixation. The oxygen atoms are released as a byproduct of water splitting and become a part of the oxygen in the Earth's atmosphere.

how can several classification categories be used on the same object????????
Answer: Several classification categories can be used on the same object by characteristics that have been given.
Explanation:
Kingdom:
The highest category into which organisms are classified.
Phylum:
A category used in the classification that consists of one or several similar or
closely related classes. You may also use DIVISION.
Class:
One or several similar or closely related orders. Similar classes are grouped
into PHYLUM.
Order:
One or several similar or closely related families. Similar orders form a
CLASS.
Family:
One or several similar or closely related genera. Similar families are grouped
into an ORDER. The names are usually determined from a type genus (Cactus,
Equus) that is characteristic of the whole family.
Genus (pl. genera):
A number of similar or closely related species. The common name of an organism
is sometimes identical to the genus, e.g. Lilium = lily. Similar genera are
grouped into a FAMILY.
Species:
A group of similar individuals that can breed and produce fertile offspring.
Similar and related species are grouped into a GENUS. Within certain groups,
species may not mate and will under different selection pressures develop
different characteristics form the main population. This is called a
subspecies.
Hope this helps!!!
By characteristics, multiple classification categories can be applied to the same object.
How the classification is done ?
The specificity of the categories within a taxonomic classification increases.Domain, the point of origin for all species, is the most general category in taxonomic classification; One of these domains is shared by all species: Eukarya, bacteria, and archaeaKingdoms are the second taxonomic classification category within each of the three domains, followed by phylum, class, order, family, genus, and species categories.Because they are more closely related, organisms become more similar at each classification category.As inaccuracies in classifications are discovered and rectified, changes to the taxonomic classification of many species must be made as scientific technology advances.A hierarchical model is used in the taxonomic classification system, which is also known as the Linnaean system after its creator, Swedish botanist, zoologist, and physician Carl Linnaeus.The groups get more specific as they move away from the point of origin, until one branch becomes a single species.For instance, scientists divide organisms into three large domains following the common beginning of all life: Eukarya, bacteria, and archaea.A kingdom is a second category that exists within each domain.The following categories of increasing specificity follow kingdoms: family, genus, class, order, phylum, and species.Plants and animals are two types of living things.Plants can be further divided into flowering and non-flowering varieties or grouped according to other characteristics.Insects, reptiles, fishes, mammals, and others are subcategories of animals.To know more about classification check this :

Answer:
1. In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.
2. When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.
3. it Disrupts the nitrogen cycle by contaminating the groundwater and making it more difficult for the plants to absorb the nitrogen and causes the phosphorus cycle to accelerate, resulting in an excess of phosphorus in water and soil.
4. The phosphorous cycle is slower than carbon cycle and nitrogen cycle because phosphorous is found mainly in very small dust particles. It moves very slowly from the deposits on land and in sediments and then it is transferred to the organism and from organism it is moved more slowly to the soil.
