Which statement best describes the flow of energy and the movement of chemical compounds in an ecosystem?
Energy flows out of living organisms and is lost, while chemical compounds remain permanently inside organisms.
Energy is transferred from organism to organism in a food chain, and chemical compounds are recycled
Energy flows into living organisms and remains there, while chemical compounds are transferred from organism to organism.
Chemical compounds flow in one direction in a food chain and energy is produced.
Answer:
This is because in biology, energy is transferred from organism to organism and some energy is lost along the way. Each energy transfer results in a loss of energy, so that energy is always at a lower level and can never be returned to its original high energy level. On the other hand, chemical elements can form products, then that reaction can be reversed and break back down into reactants. Additionally, the law of conservation of matter says that matter can't be created or destroyed, only transferred from one form to another.
Answer:
C
Explanation:
Energy flows while matter cycles

A) Identify a time when extinction rates are most rapid.
B) Describe how speciation and extinction rates affect species diversity in an ecosystem. Describe relative extinction and speciation rates in a time when species diversity would be declining in an ecosystem.
C) Explain how extinction provides opportunity for adaptive radiation.
Answer:
A.) When one species grows or decreases, which destabilizes the ecosystem and then things start to die, Example: Beetles grow in population and eat all the grass, now the grass is gone, the ants now don't have anything to eat, the ants therefore die. Now the anteaters die because they have nothing to eat, therefore the tigers decrease because they don't have anteaters. etc
B.) When there is more speciation there is more diversity and when there is less speciation there is less diversity. If the rate of speciation is higher than the rate of extinction, the number of species present will grow, and conversely, if extinction rate is higher, the number of species present will fall.
C.) When something goes extinct, new organisms are born. An example of adaptive radiation is the development of mammals after the extinction of dinosaurs.
Explanation:
The extinction rates are more rapid when one species grows or decreases, which destabilizes the ecosystem and then things start to die.
What do you mean by ecosystem?An ecosystem is a geographical area where organisms like plants, animals, and the environment cooperate to form a bubble of life. Abiotic factors, or nonliving components, as well as biotic factors comprise ecosystems.
A biological system comprises of the relative multitude of life forms and the actual climate with which they interface. Through nutrient cycles and energy flows, these biotic and abiotic components are connected.
Based on their general environment, ecosystems fall into three broad categories: terrestrial, marine, and freshwater There are distinct ecosystem types within each of these three categories based on the organisms and habitats in the environment.

In nature, which would probably be more common? Exponential or logistic growth
patterns? Why, Explain your response including evidence sited from the exercises above, your understanding of r vs
k strategists, and carrying capacity.
Answer:
In nature, the logistic growth model is more common.
Because interaction between species and the environmental conditions needed for an exponential growth model are not always possible. In fact, they are hardly possible.
Explanation:
Exponential growth model: A population that exhibits an exponential growth model increases in proportion to its size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.This model states that there is unlimited resource availability. As there are guaranteed resources and space, there is no competition. Population growth does not depend on density, nor Natality and mortality rate. There is constant growth, which is proportional to the population size. The exponential growth model is represented by an exponential curve.
In nature, this is almost impossible. Just a few organisms, such as bacteria species, might be represented by this model. But in most species, this is not feasible because available resources are not infinite, space is not infinite, and there is always an interaction between species that affects their population sizes.
Logistic growth model: The population density affects its growth. Natality and mortality depend on the population size, which means that there is no independence between population growth and population density.When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population's per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that coincides with the size of the population at the equilibrium point when the natality rate and the mortality rate get qual to each other.
The logistic growth model is represented by a sigmoid curve. In the beginning, the population grows slowly. Its size N is inferior to K.In the second stage, the population size increases rapidly but N, is still inferior to K. Gradually, the population reaches the equilibrium point, K, which depends on resource availability. N equals k. Resources become harder to find, and much of the living space is unavailable. Finally, when N is superior to K, the population must decrease in size because there are not enough resources to maintain that size.
Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.
"r" species: Their growth rate per capita is very high, which makes possible the colonization of new environments. These species are mostly small-sized organisms with short life cycles. They reach sexual maturity at early stages and have numerous offspring. They hardly spend energy in parental care. Many "r" species exhibit the exponential growth model, but not all of them.
"k" species: Their growth rate per capita is low. They are often big-sized and long-lasting species. They reach sexual maturity in advanced stages and do not have numerous offspring. They spend much time of their lives in parenting to ensure reproductive success. They are important competitors, being capable of displacing other species and monopolizing the available resources. "k" species exhibit the logistic growth model.
How do bones heal after a certain period of time. I'm giving away points
Answer:
Explanation: Well, In the first few days after a fracture/breakage in the bone, the body forms a blood clot around the broken bone to protect it and deliver the cells needed for healing. Then, an area of healing tissue forms around the broken bone. This is called a callus, (It joins the broken bones together)

Why is the first hill of a roller coaster always the tallest? Explain.
Answer:
The first hill of a roller coaster is always the highest point of the roller coaster because friction and drag immediately begin robbing the car of energy. At the top of the first hill, a car's energy is almost entirely gravitational potential energy (because its velocity is zero or almost zero
Explanation:
Because friction and drag start depriving the car of energy right away, the first hill of a roller coaster is always the steepest part of the ride.
What is friction?The resistance to motion created when two objects rub against one another is called friction. Friction occurs whenever two items come into contact with one another. Friction acts in the opposite direction from the motion and works against it. The two surfaces' respective materials have an impact on how much friction exists.
Static friction, sliding friction, rolling friction, and fluid friction are the four main categories of friction.
Friction and drag start depriving the car of energy right away. Therefore, the first hill of a roller coaster is always the tallest.

Which statement is an accurate description of genes? A) Proteins are made of genes and code for DNA B) Genes are made of proteins that code for nitrogen bases C) DNA is made of carbohydrates that code for genes D)
Genes are made of DNA and code for proteins.
Answer: The correct option is D.
Genes are made of DNA and code for proteins.
Explanation:
This is because genes contain the genetic information needed for expression of characteristics in a living organisms. Therefore, genes contain DNA which is the genetic material. Genes are housed in chromosomes located in the loci.
DNA molecule forms a chromosome, and part of the same DNA molecule produce the genes on that is found in that chromosome. The information that is present in each gene codes the production of proteins and alsothe synthesis of RNA.
A population of birds lives on a small island. Another population of the same species lives on the mainland. The distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of sandbars and tiny islands have formed between the island and the mainland. What is the most likely effect of this?
Answer: An increase in gene flow between the bird populations.
Explanation:
The population of bird species living in the island and other one in mainland are geographically isolated because of the distance between the island and the mainland is large that does not allow birds to fly and cover the entire distance. This is the reason of reproductive isolation and restricts the gene flow between the two populations. But the creation of sandbars and tiny islands between the island and mainland created a way so that island and mainland birds can meet and reproduce. This will allow the increase in the gene flow between the two separated population of bird species.

Identify the stage of translation that is directly affected by Mupirocin
Answer:
The elongation process.
Explanation:
There are 3 stages in translation/protein synthesis:
The initiation stage during which the mRNA binds to the small ribosomal subunits and the tRNA carrying amino acid binds to the mRNA at the start codon. Lastly, the large subunit of the ribosome binds to the structure to complete the initiation stage.The elongation involves the movement of the complex across each codon of the mRNA, the release of their corresponding amino acids by the tRNA. and the formation of a peptide bond between the amino acids.The termination stage during which there exists no corresponding amino acid for the codon. The system reads such a codon as a sign to stop the translation process.Mupirocin works by inhibiting one of the tRNAs. Specifically, it inhibits the tRNA carrying an amino acid known as isoleucine. Thus the translation process is disrupted and the protein synthesis truncated. In other words, mupirocin works by cutting short the elongation process of translation.
The stage of translation that is directly affected by mupirocin is the elongation process.
What is Translation?
The process by which a cell makes proteins using the genetic information carried in messenger RNA (mRNA).
Mupirocin is an antibiotic that is used to treat skin infections. It basically prevents the bacterial species to grow on our skin. The Mupirocin inhibits the tRNA that carries amino acid isoleucine. Therefore, the translation process gets affected and the synthesis of protein is trimmed. Mupirocin specifically functions as bypassing the elongation process of translation.
Thus, the stage of translation that is directly affected by mupirocin is the elongation process.

what are the types of gametes
In certain organisms, like humans, there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile. The haploid condition of the two gametes is essential so that at fertilization during sexual reproduction the integrity of the chromosomal number is maintained throughout generations.
Hope this helps.
Answer:
Examples of Gametes. The two most common gametes are sperm and ova. These two haploid cells can undergo internal or external fertilization and can differ from each other in size, form, and function. Some species produce both sperm and ova within the same organism
