Emigration is aEarthquake is a density-independent limiting factor since the reason for an earthquake to happen is because of natural phenomena such as the drifting or the natural tectonic movement of the plates of the continents and islands. In this case, the population has nothing to do with earthquakes

The scientific method includes the problem statement, previous knowledge, hypothesis and goals, methodology, results, and discusion/conclusion. The correct option is C. form a conclusion.

----------------

The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on reproducibility and refutability.

When conducting an experiment, you need to consider,

Definition and problem statement. The question for which there is not an answer yet. A question the investigator wants to answer.

Theoretical framework. Antecedents from other investigations. Previous knowledge about the study object is always required for a better understanding.

The main goal of the study is basically what the investigator wants to find out.

Hypothesis formulation. The researcher makes a hypothesis to predict or make a conjecture -not verified and which requires corroboration- about what is going on or expected to happen.

Identification of the study groups, involved variables -independent, dependent, and control-.

Methodology description. Steps needed to get data.

Results. It includes data statistical analysis. This step involves testing the observations.

Discussion and Conclusion, through which the hypothesis might be rejected or accepted.

In the exposed example, the researcher has already collected field data, and made analysis.

Probably, the marine biologist noticed, while analyzing the results, that turtles lay eggs from May to October. But there might have been a biotic or abiotic factor threatening the survival of the eggs during august.

According to the analysis the researcher concluded that the nest season involves monthes between may and october, and august turns to be the most critical month for nesting.

The correct option is C.

The act of breathing raises the blood oxygen levels, lowers the blood carbon dioxide concentration, and raises the blood pH. Acc

Alexus [3.1K]

C. a rise in blood carbon dioxide concentration

Explanation:

Negative feed back mechanism refers to the control mechanism in which a product of a particular pathway controls the switch on and switch off of that particular pathway.

Since breathing increases the blood oxygen concentration and lowers carbon dioxide concentration and pH. The sensors that regulate the breathing should respond to oxygen concentration as the carbon dioxide is the by-product of respiration and is responsible for increasing blood pH. Thus increased Carbon dioxide levels in blood is the only factor which will trigger breathing.

Skin provides protection from infection by

notka56 [123]

Answer: Option A) secreting antibodies from eccrine glands

Explanation:

The eccrine glands, a type of sweat gland found in the deep layer of the skin provides protection from infection by producing sweat that is majorly composed of water, but also immunoglobins.

These immunoglobins are designed to respond to foreign and potentially harmful pathogens, removing them and protecting the body.

Thus, the answer is secreting antibodies from eccrine glands

How does biotic carbon change to the abiotic form of carbon

Mashcka [7]

Answer:

A balanced carbon cycle is essential. Carbon is a major component in carbohydrates, fats and proteins. The carbon cycle involves the exchange of carbon between living organisms (biotic) and their atmosphere (abiotic). In the carbon cycle, carbon is constantly removed from, and returned to, the environment.

Calling all bird experts! I’m getting two parakeets soon and I was wondering if I kept only one water feeder and one food feeder

Strike441 [17]

Answer:

it really depends on the birds them selves. one time i had 2 parakeets in the same cage and there was only one food and one water container and and there wasn't a problem with them fighting or anything but i did end up putting 2 food and water containers in because i was having to re fill the containers a lot but even then they still liked to eat and drink out of the same containers. so i guess it just depends on how well Ur birds get along.
