Que tipo de ecosistema tienen los pingüinos emperador y Adelia?
Answer:
Los pingüinos Adelia viven en el continente antártico y en muchas pequeñas islas costeras circundantes. Pasan el invierno en alta mar en los mares que rodean el hielo antártico.
Los pingüinos emperador viven exclusivamente en entornos antárticos gélidos. Prefieren reproducirse durante el invierno, cuando el hielo se congela y se estabiliza. Estos pingüinos suelen crear colonias de reproducción en áreas cercanas a icebergs y acantilados helados, que los protegen de los peores vientos fuertes.

14. Brainstorm and write at least 3 potential challenges or important points to consider when conducting the described
data collection.
When conducting an experiment, there are different aspects to consider, such as the question that drives to the reseach, the hypothesis, theoretical framework, variables involved -independent, dependent, and controll-, methodology, study groups, data analisys, among others.
In the exposed example, Pincky is lacking theoretical framework, defining which are the study groups, methodology to collect data, and a description of data analysis.
---------------------
The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: reproducibility, which is the capability of reproducing the experiment in any other place by any researcher, and refutability, which is the susceptibility to be refused.
When conducting an experiment, you need to consider,
• Definition and problem statement. The question for which there is not an answer yet.
• Hypothesis formulation. A hypothesis is a scientific conjecture, not verified, that requires corroboration.
• Data collection and analysis. This step involves testing the observations.
• Results
• Verification of hypothesis. This step involves the deriving of the working hypothesis.
• Discussion and Conclusion.
Previous knowledge about the study object is always required for a better understandig. A question the investigator wants to answer. The main goal of the study, which is basically what the investigator wants to find out. The researcher makes a hypothesis to predict what is going to happen. The experiment is to be performed to answer the question. The conclusions through which the hypothesis might be rejected or accepted.
--------------
So in this experiment there must be,
Theoretical framework, such as information about the species, life stage at which they begin chirping, about external factors that might affect it or benefit it, and etcetera.
The goal: To know how temperature affects cricket´s chirping
Hypothesis: Crickets chirp less frequently under cold temperature than under warm temperature.
Variables: Temperature → Independent
Chirp frequency → Dependent
Water and food supply, light exposure, refuge → Controlled
Study groups: group of crickets exposed to a warmer temperature
group of crickets exposed to a colder temperature
Methodology: Individuals analyzed should be in the same development stage, or at least be sexually mature. Two groups of 10 individuals each should be placed under the same conditions, excepting for temperature. One of the groups should be exposed to warmer temperatures and the other one to lower temperatures. Chirps should be recorded for a week.
Data analysis: Using the chirps records, the frequency can be measured for each group. Results should be compared using different statistical analyses.
Results: Results should be clearly exposed, using texts, charts, and graphs.
Discussion and Conclusion: Hypothesis acceptance or rejection. Discussion about the expected results against the observed ones.

When many nucleotides link together, they form a biomolecule responsible for storing genetic information called nucleic acids. Thus, the correct option is B.
What are Nucleotides?Nucleotides may be defined as the basic unit of the polynucleotide chain of nucleic acids such as DNA or RNA. Each nucleotide is composed of three components. They are as follows:
A nitrogenous base.A pentose sugar (ribose in the case of RNA, and deoxyribose in the case of DNA).A phosphate group.Nucleotides are the monomers of nucleic acids. Each nucleotide is joined together by covalent bonds known as phosphodiester linkage. This linkage is present between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar of next nucleotide.
Therefore, nucleic acids are formed when many nucleotides link together which are responsible for storing the genetic information.

Why are scientific journals considered a superior resource compared to other sources of scientific information?
I NEED HELP
Scientific journals are regarded as more superior due to the fact that they are peer reviewed.
What this means is that before a scientific journal would be approved for publishing, it first has to be reviewed by some experts in that scientific field.
What these peers do is to Approve the journal, make suggestion to the work, or they can decide to reject the work if they find it unsatisfactory.

Which type of microscope would be the best tool to use to view the surface of a bacterial cell? Why?
Answer:
Electron Microscope
Explanation:
The maximum theoretical resolution of images created by light microscopes is ultimately limited by the wavelengths of visible light. Most light microscopes can only magnify 1000×, and a few can magnify up to 1500×, but this does not begin to approach the magnifying power of an electron microscope (EM), which uses short-wavelength electron beams rather than light to increase magnification and resolution.
-The electron microscope can achieve a much greater resolution than that obtained with the light microscope because the wavelength of electrons is shorter than that of light.
An Electron microscope is the type of microscope that would be the best tool to use to view the surface of a bacterial cell.
What is a Microscope?A microscope may be defined as an instrument that utilizes the arrangements of lenses to make an enlarged image of a small object.
An Electron microscope produces a higher resolution of bacterial cells as compared to a standard light microscope. This is because electrons possess a much shorter wavelength than visible light.

A certain plant has a color that can range from green to yellow. Some plants
are very green, and some are very yellow, but most are in between. What is
most likely true about this trait?
A. The color is a Mendelian trait.
B. There are several genes that control the color.
C. There are only two alleles for color.
D. Being yellow is a recessive trait.
Answer:
B. There are several genes that control the color.
Explanation:
According to the description of the trait in this question in which the plant exhibits a wide range of colors from green to yellow, it shows that the trait for color in such plant is controlled by two or more (several) genes. This kind of inheritance is called a POLYGENIC INHERITANCE.
Polygenic inheritance is a kind of non-mendelian inheritance (does not follow the principles of Mendel) in which phenotypic traits of an organism is controlled by several genes. Each gene possess two alleles, which equally contribute to the phenotypic expression of such trait. Traits controlled by polygenes do not conform to Mendel's laws of inheritance as the offsprings exhibit a range of traits from the mixture of parental traits as stated in the question.
In polygenic inheritance, most of the offsprings exhibit the intermediate phenotype (between green and yellow) with few extremes (green and yellow) due to a combination of the genes in the parental phenotypes. Hence, based on the description in the question, there are several genes that control the color trait in the plant.
Answer: B. There are several genes that control the color.

Select one:
A. P2O3 y BaO
B. Mag y N2O5
C. FeO Y SO3
D. HNO y CaO
Answer:
P2O3 y BaO
Explanation:
The oxides of the main group metals are basic in nature. They form alkaline solutions when dissolved in water. Similarly, the oxides of main group non metals form acidic solutions when dissolved in water.
P2O5 is an oxide of a main group nonmetallic element in group 15. We expect this oxide to be acidic and form acids when dissolved in water as expected from the chemistry of the group.
Also, BaO is an oxide of barium, a group two main group metal. Hence we expect this oxide to be basic in nature and form alkaline solutions.

Tara placed a grape in a solution, after sometime she noticed that the grape started to shrink.
a. Name the solution and explain.
b. Then Tara placed the raisin in a solution and noticed it started to swell up. Name the solution and explain
Answer:
a. Hypertonic solution
b. Hypotonic solution
Explanation:
There are basically 3 types of solutions in biology,
1) Isotonic-Same concentration of solute and solvent inside the grape and in the solution.
2)Hypotonic solution-More concentration of solvent in the solution than in the grape.
3)Hypertonic solution-More concentration of solvent in the grape than in the solution.
Now,
a. Tara had kept the grape in a hypertonic solution. The solvent will start draining from the grape to equalize the concentrations of solvent inside and outside. So, the grape shrank due to loss of water.
b. Tara kept it in a hypotonic solution. The solvent will start entering the grape to equalize the concentrations of solvent. So, the grape started swelling.
