Answer:
404 amino acids
Explanation:
The translation is the process by which a messenger RNA (mRNA) molecule is used as a template to synthesize a protein in the ribosomes. During translation, each triplet of nucleotides or 'codon' determines one specific amino acid of the growing polypeptide chain (i.e., the protein). In this case, the length of the fully processed AURKA mRNA consists of 1,212 nucleotides, thereby the length of the polypeptide chain will be 404 amino acids (protein length = 1,212 / 3 = 404 amino acids).

Which of the following would increase the rate of an enzyme-catalyzed reaction? *25 points!!!*
a) Increase the concentration of inhibitors present in the reaction.
b) Decrease the concentration of cofactors present in the reaction.
c) Increase the substrate concentration and increase the enzyme concentration.
d) Decrease the substrate concentration and decrease the enzyme concentration.
Answer:
c) Increase the substrate concentration and increase the enzyme concentration.
An increase in substrate concentration favors to an increase in the rate of an enzyme catalyzed reaction. Thus, the correct option is C.
What are enzymes?The enzymes is defined as the protein which act as biological catalyst and speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over.
As the enzyme molecules become saturated with substrate, this leads to increase in reaction rate levels off. As soon as the catalytic site is empty, more substrate is available to bind and undergo reaction.

Agriculture is the leading source of pollution in many countries. Pesticides, fertilizers, and other toxic farm chemicals can poison fresh water, marine ecosystems, air, and soil. They also can remain in the environment for generations.
What are the major environmental problems caused by agriculture?Agriculture contributes to a number larger of environmental problems that cause environmental degradation including climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Fossil fuels began to be used, which led to increased pollution, and the construction of factories led to the loss of habitat for many wild animals. The development of agriculture has led to the emergence of new plant varieties, domestication of animals, and disturbance of soil composition.
Therefore, some of the environmental problems caused by the agriculture and natural resource industry are well described above.

describe the three general methods used by ecologists to study organisms
Answer: The three main research methods used are observation, modeling, and experimentation.
Explanation:
Observation:
Every experiment requires observation. Ecologists must observe the environment, the species within it, and how those species interact, grow and change. Different research projects different types of assessments and observations.
Ecologists sometimes use a desk-based assessment, or DBA, to collect and summarize information about specific areas of interest. In this scenario, ecologists are using information already collected from other sources.
Oftentimes, however, ecologists rely on observation and fieldwork. This entails going into the habitat of the subject of interest to observe it in its natural state. By doing field surveys, ecologists can track the population growth of species, observe community ecology in action and study the impact of any new species or other introduced phenomena in the environment.
Each field site will differ in nature, shape, or other ways. Ecological methods allow for such differences so that different tools can be used for observations and sampling. It is crucial that sampling be done randomly to combat bias.
Modeling:
Ecological methods rely heavily on statistical and mathematical models. These provide ecologists with a way to predict how an ecosystem will change over time and react to changing conditions in a system.
Modeling also provides another way to decipher ecological information when fieldwork is not practical. There are several drawbacks to relying solely on fieldwork. Because of the typically large scale of fieldwork, it is not possible to replicate experiments exactly. Sometimes even the lifespan of organisms is a rate-limiting factor for fieldwork. Other challenges include time, labor, and space.
Modeling provides a method in which to streamline information more efficiently.
Examples of modeling include equations, simulations, graphs, and statistical analyses. Ecologists use modeling for producing helpful maps as well. Modeling allows for calculations of data to fill in gaps from sampling. Without modeling, ecologists would be hampered by the sheer amount of data that needs to be analyzed and communicated. Computer modeling allows for comparatively rapid analysis of data.
A simulation model, for example, enables the description of systems that would otherwise be extremely difficult and too complex for traditional calculus. Modeling allows scientists to study coexistence, population dynamics, and many other aspects of ecology. Modeling can help predict patterns for crucial planning purposes, such as for climate change.
Humanity’s impact on the environment will continue. It, therefore, becomes ever more crucial for ecologists to use ecological research methods to find ways to mitigate the effects on the environment.
Experimentation:
The overarching purpose of ecological methods for research is to get high-quality data. Experiments must be carefully planned.
Hypothesis: The first step in any experimental design is to come up with a hypothesis or scientific question. Then, researchers can come up with a detailed plan.
Factors that affect fieldwork experiments include the size and shape of an area that needs to be sampled. Field site sizes range from small to very large, depending on what ecological communities are being studied. Experiments in animal ecology must take into account the potential movement and size of animals.
For example, spiders would not require a large field site for study. The same would be true when studying soil chemistry or soil invertebrates. You could use a size of 15 meters by 15 meters.
Herbaceous plants and small mammals might require field sites of up to 30 square meters. Trees and birds might need a couple of hectares. If you are studying large, mobile animals, such as deer or bears, this could mean needing a quite large area of several hectares.
Deciding upon the number of sites is also crucial. Some field studies might require only one site. But if two or more habitats are included in the study, two or more field sites are necessary.
Tools: Tools used for field sites include transects, sampling plots, plotless sampling, the point method, the transect-intercept method, and the point-quarter method. The goal is to get unbiased samples of a high-enough quantity that statistical analyses will be sounder. Recording information on field data sheets aids in the data collection.
A well-designed ecological experiment will have a clear statement of purpose or question. Researchers should take extraordinary care to remove bias by providing both replication and randomization. Knowledge of the species being studied as well as the organisms within them is paramount.
Results: Upon completion, collected ecological data should be analyzed with a computer. There are three types of ecological experiments that can be made: manipulative, natural, and observational.
Hope This Helps!
The 3 general methods used by ecologists to study organisms include:
ObservationModellingExperimentationObservation involves observing organisms in their natural habitats or environments and then recording the findings. It is usually done by field surveying.
The different species living in an environment, how they interact with each other and other abiotic components of the environment are some of the observations taking during field surveys. The growth of individual species, the effects of introducing new species, their adaptations and other areas of community or ecosystem ecology can be studied through observation.
Modelling requires a simulation of real-life ecological processes through different manipulations. This could be done in the laboratory, on the field, or even on the computer. Computer modelling requires that data from observation or experimentation are supplied as input and the inputs are subject to mathematical maneuvering.
With models, complex ecological processes can be simulated and analyzed and extrapolated to deduce how things might happen in real life ecological interactions.
Experimentation involves setting up experiments following the scientific method. It can be a observational or controlled experiments.
Observational experiments requires studying organisms, populations, communities, or ecosystems through pure observation without changing or manipulating any variable.
Controlled experiments requires that variables are introduced and manipulated in some groups while some groups serve as the baseline without any manipulated variables.
Data are obtained from experiments and these are analyzed in relevant ways to support or reject hypotheses.
