The application of evolutionary principles to the study of human variation Group of answer choices allowed scientists to divide the human species precisely into well-defined races helped replace earlier views based solely on observed phenotypes; brings the focus to geographic ancestry reinforced traditional views of races as fixed biological entities that do not change supports the idea that ethnicity and race are categories that can be used interchangeably (they are the same thing) when describing groups of modern humans.
Answers
Answer:
helped replace earlier views based solely on observed phenotypes
Explanation:
The study of human variation has shown that individuals from different populations (previously erroneously considered as geographic races) are often genetically more similar than individuals from the same population. In consequence, the evolutionary approach for understanding human variation has enabled us to discard the biological race concept based solely on observed phenotypes in order to provide a more realistic variation concept associated with evolutionary human development. From this perspective, it has been possible to confirm that 1-there are no human subspecies and 2- the concept of human races is not scientifically suitable to describe human variation.

Lawmakers discuss methods of preventing pollutants that could directly start a positive feedback loop in the area shown in the picture, and this happens due to the ban on the use of chlorofluorocarbons in refrigeration systems that is in Option A.
What are the negative impacts of chlorofluorocarbons on the ecosystem?The ozone layer is an important component of the atmosphere that protects life on Earth from harmful ultraviolet radiation from the sun, and one of the major threats to the ozone layer is the release of man-made chemicals such as CFCs, which can react with ozone and deplete it, so if the ozone layer is depleted, more ultraviolet radiation can reach the Earth's surface, causing skin cancer, cataracts, and crop damage.
Hence, this happens due to the ban on the use of chlorofluorocarbons in refrigeration systems that is in Option A.

Answers
Answer:
A. The formation of fossil fuels
Explanation:
Human activities would have the least immediate impact on the formation of fossil fuels because the fossil fuels are not affected the formation of fossil fuels. The formation of fossil fuels takes millions of years because it is a very slow process. Human activities greatly affected the coral reef bleaching, over population and Eutrophication due to the release of pollutant gases in the atmosphere that greatly impact the environment.

In addition to oxygen gas, for the fermentation the basic substrate such as sugar is required. Some yeasts are required that can ferment sugars to alcohol and carbon dioxide in the absence of air.
What is Fermentation?
Fermentation is the process in which a substance is broken down into a simpler substance. Fermentation is the metabolic process through which organic molecules such as carbohydrates, such as starch or a sugar are converted into acids, gases, or different types of alcohols in the absence of oxygen or any other type of electron transport chain.
Yeasts are the organisms which preferentially metabolize sugars that are converted principally to ethanol molecule and carbon dioxide gas, however they can utilize different carbon sources, such as amino acids, organic acids, polyols, alcohols, fatty acids, and other organic compounds, depending on the species which undergo metabolic reaction.

In 2011 and 2012, scientists working on the Banana River in Florida recorded a dramatic increase in the number of manatee deaths. Over the past 50 years, this area has also seen the human population increase by more than 500,000 people. It is believed that pollution from numerous sewage tanks leaked into the water, eliminating the manatees' food source, replacing it with an alga that is toxic to the manatee. This is an example of A) a natural cycle in an ecosystem B) the effect of increased biodiversity on an ecosystem C) human actions altering ecosystems with serious consequences D) direct harvesting in an ecosystem
Answers
Answer:
C) human actions altering ecosystems with serious consequences
Explanation:
The increase in the manatee´s death during 2011-2012 might be directly related to human actions.
The increase in the number of people during the last 50 years to more than 500,000 individuals, and probably the lack of policies and regulation, lead to an enhance in water pollution by sewage tank leaks.
Pollution probably caused a gradual decrease in the manatee´s principal source of food, which also caused an increase in the toxic algae population.
Algae caused the death of manatees as a consequence of human action that altered the natural ecosystem by polluting water.

How can scientists use the fossil record to find evidence of relationships between different species?
Answers
Answer:
Species can be classified using the fossil record based on analogous or homologous structures.
Explanation:
By comparing the anatomy of both modern and extinct species, paleontologists can infer the lineage of those species, scientists use the fossil record.
What is Fossil?A fossil is defined as the preserved remains, imprint or trace of a once living thing from a past geological age. Some examples of fossils are bones, shells, exoskeletons, stone marks of animals or microbes, objects preserved in amber, hair, petrified wood, and DNA residues. The totality of fossils is known as the fossil record.
Fossils form the morphological, or anatomical record, through comparing the anatomy of both modern and extinct species with the comparative anatomy of present-day organisms, paleontologists can infer the lineage of those species.

Los métodos hormonales son eficientes porque: * A: impiden la entrada de los espermatozoides C: Se inhibe (no se desarrolla) la ovulación B: El óvulo jamás se encuentra con el espermatozoide D: Los espermatozoides quedan atrapados y no llegan al óvulo
Answers
Answer: C: Se inhibe (no se desarrolla) la ovulación.
Explanation:
Los métodos anticonceptivos se utilizan prevenir el embarazo no deseado, evitando que el esperma fertilice a un óvulo. Hay distintos tipos, los cuales se clasifican en:
Anticonceptivos hormonales: Contienen hormonas, tales como estrógeno y progesterona, que previenen la ovulación (es decir, la liberación de óvulos de los ovarios). De esta manera, al no haber óvulo disponible, por mas que hayan espermatozoides, no va a ocurrir ninguna fecundación. El método mas conocido es la píldora o pastilla anticonceptiva. Anticonceptivos de barrera: Proveen una barrera física que impide la fecundación al impedir el encuentro entre el óvulo y el espermatozoide. Por ejemplo, el uso de preservativos o condones. En estos métodos, se impide la entrada de los espermatozoides, no se encuentran con el óvulo y la esperma queda atrapada dentro del condón. Anticonceptivos permanentes: Proveen un método permanente como por ejemplo el Dispositivo Intrauterino que se coloca en el tracto uterino con una vida media de meses o años y posee un efecto espermicida que mata a los espermatozoides (por lo que no lograrán encontrar un óvulo). Otro ejemplo es la vasectomía, la cual es una cirugía que corta los conductos deferentes que transportan a los espermatozoides por lo que ya no pueden salir de los testículos para producir la fecundación (quedan atrapados dentro de los testículos, no entran al tracto uterino y no encuentran al óvulo)Tanto los métodos de barrera como los permanentes, no inhiben la ovulación aunque si impiden que el óvulo se encuentre con el espermatozoide. Entonces, los métodos hormonales son los únicos que logran inhibir la ovulación. Las píldoras que poseen las hormonas previamente mencionadas pero fabricadas sintéticamente. Las mismas mimetizan el efecto de las hormonas naturales producidas por el cuerpo, alterando el ciclo menstrual regular y así evitan el embarazo ya que no habrá óvulo disponible para fecundar. Además, también pueden alterarla mucosidad en el cuello del útero para que los espermatozoides no pueden atravesarlo y llegar al óvulo. De todas maneras, el objetivo principal y mas importante de los métodos hormonales es bloquear la ovulación.
A student set up an experiment to show that carbon dioxide is consumed by Elodea plants during photosynthesis. She filled two test tubes with distilled water and placed a piece of Elodea in one of the tubes. She added a drop of phenol red which is a pH indicator to both tubes. She blew in each tube to add carbon dioxide, which caused the distilled water to become more acidic. She exposed both tubes to the light and recorded any color changes in the liquid in the tubes. What is the negative control in this experiment
Answers
Answer: The NEGATIVE CONTROl is the test tube that is filled with ONLY distilled water.
Explanation:
A negative control of an experiment is carried out alongside the main primary experiment except that the treatment is changed to something that is predicted to have no result. In the negative control, the student does not expect any response. This would help the student compare the result of a new experiment against an already known existing results.
Analysing the experiment carried out by the student, She filled two test tubes with distilled water and placed a piece of Elodea in one of the tubes, leaving the other without a plant. The other test tube that contains only distilled water is the negative control because she wasn't expecting any result from it. It's also served as a control sample to the primary experiment. This is observed as she blew in each tube to add carbon dioxide, which caused the distilled water to become more acidic. This would help the student know that the that experimental results are valid and to ensure that time is saved.
