A relationship in which one organism benefits while the other is not harmed but does not receive any benefits is called commensalism.
An example of a symbiotic relationship between two creatures is commensalism, in which one species gains from the association while the other is unaffected and neither helped nor damaged. The creature that benefits is referred to as a commensal, and the organism that neither benefits nor suffers harm is referred to as a host.
In this type of connection, the commensal receives benefits from the host, such as food, housing, or transportation, without having any discernible negative effects on the host. It is crucial to understand that commensalism differs from parasitism, where one organism gains while the other suffers, and from mutualism, when both species gain.

They include; predation, mutualism, parasitism and commensalism. -Commensalism is a type of relationship where one of the organisms benefits greatly from the symbiosis. The other organism is not helped but is not harmed or damaged from the relationship.
B. Qualitative
C. Descriptive
D. Mixed methods
ANSWER:
The correct option is B- Qualitative.
EXPLANATION:
When the growth of corn has to be recorded, the quality of the corn grown in different soils needs to be recorded. Qualitative methods are best used to classify quality of anything.
Qualitative data basically is non-numerical data which in the case of corns can be the length of the corn plant, the sweetness of the corn kernel or the hardness or softness of the corn. This data cannot be recorded using numerical values and so other methods of data recording cannot be used.
Answer:
a. quantitative
Explanation:
everyone said that it was qualitative, but no that is incorrect. I was retaking the test and it shows me that a. is the correct answer
Answer and explanation;
The steps followed in an experiment include;
-Observation; this involves
taking note of something such as a curious phenomenon worth further thought and investigation
-Research; it involves forming a question so as to find out more about the natural phenomenon observed.
-Hypothesis, this is an informed guess as to the possible answer of the question.Its purpose is not to arrive at the perfect answer to the question but to provide a direction to further scientific investigation.
-Experiment, the hypothesis formed must be tested by conducting a well designed and controlled experiment. Its is an important step as it proves whether the hypothesis is correct or wrong.
-Analysis; it entails taking down the results and analyzing it together with the data and suing it to draw conclusion regarding the strength of the hypothesis.
-Conclusion; From the analysis a conclusion about the hypothesis can be drawn, explaining why the phenomenon occurs.
-Publish; the results may then be published as a reference and for future use and comparison.
The steps followed in an experiment are as follows: Observation, Research, Hypothesis, Experiment, Analysis, Conclusion, and Publication.
1. Observation: This involves noticing and identifying a curious phenomenon or event that requires further investigation.
2. Research: Conduct background research to gather existing knowledge and information related to the observed phenomenon. Formulate a question or hypothesis based on this research.
3. Hypothesis: Develop an informed guess or prediction about the possible answer to the research question. The hypothesis provides a direction for the experiment and serves as a tentative explanation for the observed phenomenon.
4. Experiment: Design and conduct a well-controlled experiment to test the hypothesis. Plan the procedures, identify variables, establish control groups, and collect data through systematic observations and measurements.
5. Analysis: Analyze the collected data using statistical or analytical methods. Look for patterns, trends, and relationships in the data to determine whether the hypothesis is supported or refuted.
6. Conclusion: Based on the analysis of the data, draw conclusions about the hypothesis. Explain the findings and discuss their implications in relation to the original research question. Assess the strength of the hypothesis and its alignment with the observed data.
7. Publication: Share the results of the experiment by publishing them in a scientific journal or presenting them at conferences. This allows other researchers to review, replicate, and build upon the findings, contributing to the scientific knowledge and understanding of the phenomenon.

Two or more genes are required to determine a polygenic trait. Thus, option B is correct.
Human sex gets decided by the function of SRY gene which possessed by with or without of Y chromosome. The hormone of anti-mullerian and testosterone produced from cells when activating the SRY gene. It generally confirms the development of single-male reproductive systems.
The scenario in humans, the sex ration gets affected by the male parent's hormone level. Also, in XY sex evaluation system, the sperm of male takes part in X or Y chromosome whereas the ovum from female contributes to X chromosome. This greatly results in offspring - either male (XX) or female (XY).
She creates the Punnett square cross below to show sex inheritance. She come to know that both parent determines the sex of a baby and it is when you put xx and xy on a punnet square there are equal amounts male and female.
Therefore, Two or more genes are required to determine a polygenic trait. Thus, option B is correct.

Answer:
B
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Photosynthesis and cellular respiration are two interdependent processes. Photosynthesis uses carbon dioxide and water to produce carbohydrates and oxygen, while cellular respiration uses these carbohydrates to produce energy, carbon dioxide, and water. They form a cyclical biological harmony vital to life.
Photosynthesis and cellular respiration are two fundamental processes in the carbon cycle that share reciprocal reactants and products. In photosynthesis, plants absorb light energy to build carbohydrates in chloroplasts, using carbon dioxide and water. The resulting byproduct of this process is oxygen. On the other hand, cellular respiration occurs in the cytoplasm and mitochondria, where organisms metabolize these carbohydrates to produce energy, in the process releasing carbon dioxide and water. Both processes use electron transport chains to capture the energy necessary to drive other reactions.
Thus, photosynthesis and cellular respiration are linked in a cyclical biological harmony; they provide the life-sustaining energy that originates millions of miles away in the sun. Photosynthesis produces the carbohydrates needed for cellular respiration, and cellular respiration releases the carbon dioxide required for photosynthesis, creating an interdependent cycle vital to most forms of life on Earth.
