Scientists are able to comprehend the interior of the Earth by studying seismic waves. These waves, which are made up of energy, behave like other types of waves including sound, light, and water waves as they travel through the Earth's atmosphere.
We now recognize the locations and causes of the majority of natural disasters thanks to the scientific approach. For instance, we now know why over 90% of all earthquakes and volcanoes occur in the Pacific Ocean's outer borders, known as the Ring of Fire, thanks to the idea of plate tectonics. The explanation for why certain volcanoes are more explosive and active than others has also been aided by the notion of plate tectonics. We also know that various tectonic plate borders result in various fault lines, and consequently, various kinds of earthquakes.

why is it imprtant to understand that racial categories are based upon perceptions of phentotypic features and not of genotypes
Is it crucial to recognize that racial classifications are based on perceptions of phenotypic characteristics rather than genetics due to the fact that race is socially rather than biologically generated.
What is meant by phentotypic?In genetics, an organism's phenotype is the collection of attributes or traits that can be seen in it. The expression alludes to an organism's morphology, and physical form and structure, including to its biochemical and physiological traits, behavior, and the results of that behavior. An observable characteristic is simply referred to as a "phenotype." Pheno, which has the same root as the term "phenomenon," simply means "observe." It can therefore refer to everything from a common attribute, like height and hair color, to the existence or absence of the a disease. This is also an observable type of the an organism. A clinical manifestation of the a person with a particular genotype; the observable characteristics of an individual which are the outcome of gene expression.
What are phenotypes examples and how you determine it?Examples of phenotypes in humans include height, blood type, eye color, freckles, & hair color. Phenotypes also include characteristics other than those of the physical body. A phenotype can also be a behavior.
We examine the alleles of a parent organisms and predict the frequency at which those genes would be expressed by the offspring in order to determine a phenotypic ratio. Almost all of the time, we were aware of the alleles' expression and appearance.

"Energy saving can be known as energy production". Justify the statement.
Answer: Energy saving can help produce more energy. Increases food and item production.
Explanation:
Which statement is NOT true about subatomic particles? a) In chemical reaction the number of protons change. b) Neutrons have no electrical charge. c). Electrons in the outer orbit determine the chemical reactivity of the atom d) Electrons are found in orbitals outside of the nucleus. e) Protons are found in the nucleus.
The statement which is not true about subatomic particles is: (a) In chemical reaction the number of protons change.
Subatomic particles are the materials that make up an atom. They are smaller in size than the atom. There are three sub-atomic particles: protons, neutrons and electrons. The proton and neutron make up the nucleus of the atom, and the electrons reside in a cloud form surrounding the nucleus.
Protons are the positively charge sub-atomic particles. Since they form the core (nucleus) of the atom therefore they cannot take part in any chemical reaction and hence their number never changes. If the number of protons change then the identity of the atom will also change.

The correct option is B : Maintaining a constant supply and concentration of ATP. As we just saw, for cells to create and sustain the biological order that keeps them alive, they need a steady flow of energy.
Food molecules' chemical bonds, which act as the fuel for cells, are the source of this energy.

Grain size represents the conditions under which the sediment was deposited.
Explanation:
suppose a type of plant has only chloro phylls a and b and is exposed to different wavelengths of light. at which wavelengths would there be the greatest amount of carbon dioxide in the air around plants? The least? explain your answer
Light is the most efficient and important thing for the process of photosynthesis.
Photosynthesis is dependent on light intensity when low intensity light falls on the surface the amount of carbon dioxide fixed will also be low .Plants there fore proceeds with the process of photosynthesis in the 400-700 nm range of the light. Which is one of the most suitable light range for the plants.
Hence, light Color plays a vital role in photosynthesis process this function is most rapid in the blue and red colour wavelengths of the visible white light that falls on the surface. Blue and red light provide a better environment for plant growth .

What is the condition of greater metallic character?The condition of greater metallic character is higher the capacity to lose the electron, greater the metallic character. In bigger sized atoms outermost electrons can easily be lost to others because they are at larger distance from the nucleus.
In a group, the size of the atom increases when we go down the group. So other elements of boron- group show metallic character.

00. the process of glycolysis is the breakdown of what molecule in the body? protein triglycerides glucose fatty acids
The process of glycolysis is the breakdown of fatty acids molecule in the body.
Glucose is metabolized to pyruvate by glycolysis in the cytoplasm, and pyruvate is fully oxidized to ATP by the TCA cycle and oxidative phosphorylation in mitochondria. Upon feeding, fatty acids are synthesized by de novo lipogenesis using products of glycolysis.
Glycolysis is the process by which glucose is broken down for energy. Produces his two molecules of pyruvate, ATP, NADH, and water. This process takes place in the cell's cytoplasm and does not require oxygen. Found in both aerobes and anaerobes.
This is the first step in cellular respiration. In glycolysis, sugar molecules are broken down to release the energy needed for cell metabolism. It is found in the cytoplasm of cells. The main purpose of glycolysis is the synthesis of thousands of ATP molecules that are used in various cellular metabolisms.

Discuss environmental changes, plate tectonics, landscapes, resources and major extinction events.
The convecting mantle, upon which the tectonic plates lie, is what moves them. These plate movements may be responsible for both obvious geologic occurrences like earthquakes and volcanic eruptions as well as more subdued yet exquisite ones like the formation of mountains.
Mountains and volcanoes that arise as a result of the movement of the plates can also influence the climate. The climate may be affected by large mountain ranges by altering air circulation throughout the world. Mountains, for instance, may cause warm air to be redirected to colder areas.
The distribution, size, and depth of ocean basins are determined by the movement of tectonic plates, which also affects how water is distributed across the continents.

Messenger rna carries information from the dna to cellular components called , which play a key role in the synthesis of polypeptides.
The "machines" that propel protein synthesis are called ribosomes, which receive the protein blueprint from a cell's DNA via messenger RNA (mRNA).
What part in the synthesis does messenger RNA play?Messenger RNA provides the ribosome with the instructions needed to produce proteins. Amino acids are what proteins are made of. Transfer RNA is a different type of RNA that carries each amino acid in a protein to the ribosome.
What is the procedure by which a specific polypeptide is produced on a ribosome using an mRNA molecule?During translation, ribosomal subunits create a sandwich-like structure on the strand of mRNA. From there, they are drawn to the amino acids connecting tRNA molecules (circles). A long chain of amino acids is created as the ribosome transforms the mRNA sequence into a polypeptide, or new protein.
