Which scientist developed the planetary model that stated electrons were found in specific energy levels around the nucleus?
Ernest Rutherford developed the planetary model that stated electrons were found in specific energy levels around the nucleus.
The Rutherford model, also known as the Rutherford atomic model, nuclear atom, or planetary model of the atom, is a description of the structure of atoms that was put out in 1911 by physicist Ernest Rutherford, who took birth in a city of New Zealand. According to the idea, an atom consists of a small, compact, positively charged core called a nucleus, which is where almost all of the mass is concentrated.
The light, negatively charged electrons then orbit the nucleus at a slight distance, much like planets orbit the Sun. Under the guidance of Rutherford and German physicist Hans Geiger in 1909, Ernest Marsden, a student, conducted a series of experiments that revealed the scattering of alpha particles from thin gold foil.
This resulted in the hypothesis that the nucleus was tiny and dense.

The following picture shows the three primary types of plate boundaries. Which boundary is being shown in label D? Oconvergent boundary zone ODivergent boundary zone Oplate boundary zone Otransform boundary zone
The type of plate boundary which is shown in label D in the picture is convergent boundary.
What is convergent boundary and what are its features?Two plates travelling in the opposite directions clash at a convergent boundary. The less dense plate, usually the continental plate, is subducted beneath the denser plate, which is often the oceanic plate. The plates often stretch downward at the boundary as a result of the tremendous stress from the subduction, leading to the formation of an oceanic trench.
Volcanic arcs, which are chains of volcanoes, are a typical feature of convergent boundaries. These are created by the fractures that occur at the border brought on by the stress between the two plates. The melting of the subducted plate causes the magma to rise through the fractures as it descends into the mantle. A volcanic mountain is formed at the surface by the magma. There will grow a number of mountains (a mountain chain) as a result of the boundary's multiple cracks.
In the given picture, at label D, features like trench and subducting plate signify the convergent boundary.

1. What makes Charles Darwin an important person to learn about?
Answer: Charles Darwin is an important person to learn about because he is the scientist who developed the theory of evolution by natural selection. This theory explains how species change over time through the process of natural selection, where individuals with traits that are better suited to their environment are more likely to survive and reproduce.
Darwin's theory of evolution by natural selection has had a profound impact on the scientific understanding of the natural world, and it is considered to be one of the most important scientific theories of all time. It has been supported by a vast body of scientific evidence and has helped to explain a wide range of phenomena in biology, including the diversity of life on Earth and the adaptations of organisms to their environment.
In addition to his contributions to science, Darwin is also an important figure in the history of science. He was one of the first scientists to systematically study and document the process of evolution, and his work laid the foundation for many of the advances that have been made in the field of biology over the past 150 years. His ideas have also had a significant impact on other fields, including psychology, sociology, and anthropology. As such, learning about Charles Darwin and his contributions to science can help us to better understand the natural world and the forces that shape it.

if natural fires and herbivores can both reduce the abundance of competitively superior plants, how should this affect the number of other plant species that can persist in the community?
It can cause woody plants to proliferate and outcompete plants that have adapted to fire, reducing the number of plant species that can survive in the community.
Resources are often scarce in a habitat, and many species could compete for them. Plants in a garden, for example, may compete for soil nutrients, water, as well as light. Interspecific competition has a negative overall effect on both species involved. That is, if the other species did not exist, each species would fare better.
Interspecies competition occurs when two species compete for the same limited resource. Both species suffer as a result of competition. The ecological role of a species is defined by the set of conditions, resources, as well as interactions that it requires. According to the competitive exclusion principle, two species cannot coexist if they occupy the same niche.

what is the viral envelope, and what does the presence (or absence) of it tell you about the type of virus?
The envelope, which is derived from the host cell membrane, surrounds the viral capsid and serves as just an additional barrier to a external environment. The vast majority of animal viruses are enveloped, whereas the vast majority of viruses that infect plants or bacteria are not.
The viral genome is packaged in a protein coat known as the capsid in virus particles. For some viruses, the capsid is surrounded by a lipid bilayer containing viral proteins, which typically include proteins that allow the virus to bind to host cells. The virus envelope is a lipid and protein structure derived from the host cell membranes. Viral genetic material is contained within protein structures known as capsids.
Viruses are classified into two types: enveloped viruses, which have an outer lipid membrane, and nonenveloped viruses, which do not. The envelope, when present, contains viral proteins that mediate binding to host cells. When there is no envelope, the outer capsid proteins perform this function. Nonenveloped viruses, in general, are more stable and can survive in the environment for much longer. The method of viral entry and exit from host cells is determined by capsids and envelopes.

if cooking a beef roast with significant amounts of collagen, how can the meat be most effectively tenderized? a.mechanically tenderize meat or cut the collagen from the meat b.use a moist-heat cooking method to change the collagen to gelatin c.slice thinly across the grain of the meat d.roast to rare or medium rare
Option B - Whenever roasting beef that contains a lot of collagen, To make gelatin, cook the collagen using a wet heat method.
At 160/70, collagen begins to break down into gelatin. The meat becomes dryer, but at 160F the collagen-containing connective tissues start to turn into gelatin. Muscle fibers that had been tightly bound start to easily stretch apart over time. The flesh appears more tender because of the succulence that the gelatins produce, despite the fact that the fibers are still very stiff and dry.
Therefore, we want our meat to be cooked tenderly so that the rough collagen is transformed into gelatin while minimizing moisture loss. The fact that these techniques conflict with one another is what makes cooking meat difficult or problematic. However, temperatures must be lower than 130F in order to avoid moisture loss. It takes longer and higher temperatures to transform collagen into gelatin.

One molecule of glucose is converted into two molecules of pyruvate by the cytosolic process known as glycolysis, which also results in the net generation of two molecules each of ATP and NADH (nicotinamide adenine dinucleotide).
To refuel ATP in muscle, three energy mechanisms work: phosphoglycation, glycolysis, and mitochondrial respiration. While glycolysis and the mitochondria are in charge of cellular ATP synthesis, the sarcoplasmic reticulum (SR) is the main regulator of calcium storage, release, and reuptake in skeletal muscle. Due to their high energy needs, skeletal muscle cells have many mitochondria that enable them to produce enough ATP. The process by which cells produce ATP by dissolving the organic materials in food is known as cellular respiration. Muscle cells have the capacity to make ATP either by aerobic respiration, also known as breathing with oxygen, or through anaerobic respiration, also known as fermentation or anaerobic glycolysis.

sexual selection in a population choose one: a. can lead to physical differences between the males and females of a species. b. does not lead to evolution. c. reduces genetic variation in the population. d. always favors individuals with a higher survival potential.
The right response is option a, which states that morphological distinctions between males and females of a species can result from sexual selection in a population.
The tail of a peacock is a good illustration of partner selection. Peahens choose peacocks with huge, vibrant tails, which allows those peacocks to mate more frequently and produce younger ones. The genes for a long, colourful tail will be passed down from the father to the male peachicks, who will inherit these genes and develop comparable tails. There are two main factors that influence sexual selection. One is the preference of one sex (typically females) for members of the opposite sex who display particular features. The other is higher strength, which (often in males) results in better success in courting females.
So, we can conclude that option a, which claims that sexual selection can lead to physical differences between males and females of a species in a population, is the appropriate response.
