Scientific method lab results

Answers

Answer 1

Answer:

Answer:

1.Observation and description of a phenomenon. The observations are made visually or with the aid of scientific equipment.

2.Formulation of a hypothesis to explain the phenomenon in the form of a causal mechanism or a mathematical relation.

3.Test the hypothesis by analyzing the results of observations or by predicting and observing the existence of new phenomena that follow from the hypothesis. If experiments do not confirm the hypothesis, the hypothesis must be rejected or modified (Go back to Step 2).

4.Establish a theory based on repeated verification of the results.

Answer 2

Answer:

Final answer:

The scientific method is a structured approach used in scientific research. It begins with an observation, then a hypothesis is formed, and experiments are conducted to test this hypothesis. Lab results reveal whether the hypothesis was correct, needs revision, or is incorrect.

Explanation:

The scientific method is a systemic approach used in science to find answers to questions or solve problems. It consists of a sequence of steps, each of which plays an integral part in the research process.

The first step is to make observations about the world around us. With observations, we form a hypothesis, which is a tentative explanation for the observed phenomenon. This hypothesis becomes the basis for the experiment, where we test to see if it holds true.

The lab results are findings obtained from an experiment. They provide detailed information on whether the hypothesis stands or not. They may either support the hypothesis, totally debunk it, or partially prove it. Analyzing and interpreting these results is key in scientific research. For instance, if your hypothesis is 'All plants turn towards the sunlight,' you would study several plant species over a period of time to either support or refute this hypothesis based on the results. If some plant species consistently do not turn towards the sun, your lab results would falsify the hypothesis, leading to its revision.

What is niche diversity?

Answers

Niche diversity refers to the evolutionary process in which species diverge in order to take advantage of open niches in their environment. This can also be seen in species that are somehow threaded from a common ancestor they share.Hope this helps:)

Insulin is an important hormone that allows the body to use glucose from food. After an individual eats a meal, glucose travels through the blood stream and reaches beta cells in the pancreas. The glucose causes the beta cells to release insulin. Insulin then travels through the blood stream and attaches to insulin receptors on other cells, which allows them to take in glucose and use it for energy.What does this information best demonstrate?

Answers

Insulin is one of the significant hormones in the human body. The information about insulin and its mechanisms explains how the human body uses food for its energy requirements.

Generally, glucose obtained from the food that travels in the bloodstream is responsible for elevating the blood sugar level. The pancreas is an organ that helps in releasing insulin for controlling the blood glucose level. Insulin tends to get released in a feedback mechanism depending on the blood sugar level.

The mechanism of insulin best demonstrates the following:

Insulin along with glucagon helps in maintaining the state called homeostasis for the steady condition in the human body
Insulin is considered vital for cells to utilize glucose and obtain energy

Thus, the mechanism of insulin in the human body explains how energy is utilized by different cells and how insulin is important in maintaining homeostasis.

Biology students used raw eggs in an experiment on tonicity and osmosis. The students put their eggs into vinegar to remove the shells. The vinegar was used to remove the shell form the raw egg. What other effect(s) did the vinegar have on the egg?a: the vinegar solution was hypotonic , causing the egg to gain mass
b: the vinegar solution was hypotonic , causing the egg to lose mass
c: the vinegar solution was hypertonic , causing the egg to gain mass
d: the vinegar solution was isotonic to the egg so the mass remained constant

Answers

a) is the right answer

A would be the answer because the vinegar solution had a Chemical reaction with the outer shell of the egg causing the egg to swell and absorb the vinegar
