A scientist is studying the population of a particular species of beetle in an ecosystem. The beetles currently have an estimated population of 11,500 individuals on a wildlife preserve of 115 hectares. (One hectare is equal to 2.47 acres of land.) The scientist calculates the carrying capacity at 14,600 individuals.
PART B
What will likely happen to the population of these beetles during the next year if the resource level stays the same? Explain your answer.
PART C
These beetles have a uniform distribution. In year 1, how many beetles are there per hectare? How many beetles per hectare were there in the year the beetles reached carrying capacity? Round up or down to the nearest whole number, if necessary.
PART D
During the year the beetles reached carrying capacity, a flood in the region decreased the population to about 77 beetles per hectare. What is the total estimated population of the beetles after this disaster? What percentage of the carrying capacity is the population now?
PART E
Over a period of time, the beetles once again reached carrying capacity and sustained it for many years. However, pollution from a nearby factory leaked into the ecosystem, making 55 hectares of the land uninhabitable to the beetles. Predict how the estimated carrying capacity will change and explain your reasoning for your estimation.

How is reproduction different than the other five characteristics of living cells?
Answers
Answer:
because reproduction is nature gifted and it is the way to increase population but living cells are the cells which keeps us alive
Reproduction differs from the other five characteristics of living cells because of the ability to replicate for continued existence.
The characteristics of living things include -MR NIGER D(acronym to remember)
Movement RespirationNutritionIrritabilityGrowthExcretionReproductionDeathNow Reproduction differs from all the others because while others are processes that organisms need for existence or survival,Reproduction on the other hand is the reason for the continuation of existence of species(creation of a copy).

Tides occur in ocean,why?
Answers
Answer:
¿Qué Causa las Mareas? Podemos decir de una manera sencilla que las fuerzas de atracción que tanto el sol como la luna ejercen sobre la tierra, permiten una deformación y consecuente movimiento de las masas de agua de mares y océanos; esto hace que los niveles de agua suban y se formen las mareas.NOTA: Aquí anexo la respuesta en ingles.What Causes the Tides? We can say in a simple way that the attractive forces that both the sun and the moon exert on the earth, allow a deformation and consequent movement of the water masses of the seas and oceans; This causes the water levels to rise and tides to form.

C.
The mutation is an insertion which causes an increase in the genetic variation of a population.
D.
The mutation is a substitution which causes an increase in genetic variation of a population.
Answers
The mutation from AATTAG to AAATAG is a substitution which causes an increase in genetic variation of a population.
MUTATION:
Mutation refers to any change in the nucleotide sequence of DNA molecule. Mutation can be of different types depending on how it occurs. A substitution mutation is that in which one or more nucleotide base is replaced by another in the sequence. In this question, an original sequence of DNA is given as AATTAG. It was mutated to AAATAG via the replacement of 'T' with 'A'. This means that it is a substitution mutation. However, this mutation will cause an increase in the genetic variation i.e. difference in a population.Learn more at: https://brainly.com/question/21220597?referrer=searchResults

Describe the roles of the soil organisms in the carbon cycle
Answers
Carbon cycle is a biogeochemical cycle by which carbon is exchanged among the different components of the Earth.
Carbon cycle along with the Nitrogen cycle and the Water cycle, comprises a sequence of events that are key to make Earth capable of sustaining life.
It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks.
The terrestrial carbon cycle is dominated by the balance between photosynthesis and respiration.
Carbon is transferred from the atmosphere to soil via ‘carbon-fixing’ autotrophic organisms, mainly photosynthesizing plants and also photo- and chemoautotrophic microbes that synthesize atmospheric carbon dioxide (CO2) into organic material.
Fixed carbon is then returned to the atmosphere by a variety of different pathways that account for the respiration of both autotrophic and heterotrophic organisms.
The reverse route includes decomposition of organic material by ‘organic carbon-consuming’ heterotrophic microorganisms that utilize the carbon of either plant, animal or microbial origin as a substrate for metabolism, retaining some carbon in their biomass and releasing the rest as metabolites or as CO2 back to the atmosphere.
What is the role of soil organisms in the Carbon Cycle?Soil Organisms or Microbes are critical in the process of breaking down and transforming dead organic material into forms that can be reused by other organisms and thus the microbial enzyme systems involved are viewed as key ‘engines’ that drive the Earth's biogeochemical cycles.
Soil microbes essentially transfer carbon between environmental compartments to fulfil their fundamental goal: survival through reproduction.
Thus, microbes utilize different organic and inorganic forms of carbon as carbon and energy sources.

A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals
called mutagens, or infection by viruses. Germ line mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on.
Mutation has been the source of many Hollywood movies, but it's really a simple process of a mistake made in a DNA sequence as it's being copied. Some of that's just the background noise that DNA copying is not perfect, and we should be glad of that or evolution couldn't operate. But mutation can also be induced by things like radiation or carcinogens in a way that can increase the risk of cancers or birth defects. But it's pretty simple; it's basically an induced misspelling of the DNA sequence.
That's a mutation.
When a variant alters a protein that plays a critical role in the body, it can disrupt normal development or cause a health condition. A condition caused by variants in one or more genes is called a genetic disorder. In some cases, gene variants are so severe that they prevent an embryo from surviving until birth.

A concept that is easier to understand using a model is the atomic structure.
The atom is the smallest particle of a substance that can take part in chemical reaction. All substances are made up of atoms but these atoms are not visible to the naked eyes.
The concept of atomic structure lies at the base of understanding science. Hence, a science student must thoroughly comprehend this concept.
Since atoms can not be seen with naked eyes, it is imperative to use a model to aid the learner in conceptualizing the structure of atoms.
