A gradual in scientific knowledge happens as many researchers face many individuals hypothesis. The given statement is true.
What is scientific knowledge?Scientific knowledge is defined as a systemic explanation of phenomenon or behavior of interest that are obtained using the scientific method.
The principal on which scientific knowledge depends is "the test of all knowledge is experiment".
The fact which makes scientific knowledge different from other knowledge is that it depends upon fact and scientific resources as well as data.
Scientific knowledge helps us to improve and develop new technology find solution of practical problems and make informed decisions.
The procedure of aquairing scientific knowledge is a result of practice of the several method such as observation, filtering hypothesis, deduction of test for hypothesis following testing and experimentation which lead to confirmation or failure of the hypothesis.
Therefore, a gradual in scientific knowledge happens as many researchers face many individuals hypothesis. Thus, the given statement is true.

A student wants to create a liquid volcano. The student observes bubbles in the soft drink prior to opening it. The student first proceeds to open the soft drink bottle and place it on the floor. Next the student drops candy tablets into the drink using a rolled piece of paper, so that the tablets are able to fall into the drink continuously. The student notices a very powerful reaction as the drink fizzes and starts to bubble In this scenario, what would be the catalyst ? O The candy tablets being added to the drink The gasses being released when the drink was first opened The piece of paper being placed over the soft drink O The container that holds the liquid
Answer: the candy tablets being added
Explanation:
just took it
The candy tablets being added to the drink would be the catalyst of the reaction in the drink.
WHAT IS A CATALYST:
A catalyst is any substance that makes the rate of a chemical reaction faster by lowering the activation energy needed for the reaction to occur.Catalyst makes a reaction proceed faster than usual. In this case, a student who wants to make a liquid volcano notices bubbling in a sealed drink bottle. She then opens it and began to add candy tablets using a rolled piece of paper.She notices that a very powerful reaction occured as she constantly puts the candy tablets in the drink. This suggests that the catalyst of this reaction in the drink is the CANDY TABLETS.Learn more: brainly.com/question/1565029?referrer=searchResults
Describe at least two biological systems. Explain how the systems are independent from an interconnected with each other.
The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe. The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
Biological systems are made up of group of organs that perform a particular function.
Biological systems are peculiar to higher organisms. Examples include:
Digestive system: this system consists of organs that brings about the assimilation and digestion of food. It carries out this function through the mouth, stomach, small intestine and large intestine.irculatory system: this system serves the basic function of transporting soluble food, excretory products and oxygen, throughout the body. This system consists of the heart, arteries, veins and so on.The division of labour in the body systems leads to efficiency of their various functions.
But the two biological systems mentioned above are interconnected. Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System which then carries those nutrients where they need to go.

Which biotic factor would be most effective in maintaining homeostasis in an ecosystem
1. The absence of large trees
2. The presence of many ponds
3. The presence of many species
4. The absence of predators
Answer: 3. The presence of many species
Explanation:
A biotic factor that would be most effective in maintaining homeostasis in an ecosystem is as follows:
The presence of many species.Thus, the correct option for this question is C.
What is an Ecosystem?An ecosystem may be defined as a place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.
Among the given options, the pond is classified as a source of abiotic factors. While the absence of trees is not favorable for any ecosystem in order to maintain homeostasis. The absence of predators makes a population grow significantly but does not maintain homeostasis, it is also not considered.
The presence of many species increases the overall diversity of any ecosystem. It also provides flexibility to the surrounding atmosphere. This statement is typically involved in the effective maintenance of homeostasis in an ecosystem.
Therefore, the correct option for this question is C.

A student wanted to know which sugar would yield the greatest amount of energy for the cell when metabolized by mitochondria. The student mixed yeasts in three different sugars/water solutions: maltose, glucose, and sucrose. Write a possible hypothesis for this experiment
Answer:
A possible hypothesis would be:
IF a yeast cell is supplied with maltose sugar, THEN it would yield the greatest amount of energy when metabolized by bacteria
Explanation:
The hypothesis is a testable explanation aimed at providing a theoretical explanation to a question. The hypothesis is a predictive statement about the possible solution, which can be tested. A hypothesis must be testable via experimentation. It often has an IF, THEN format.
Hence, in the case experiment where a student wanted to know which sugar (maltose, glucose or sucrose) would yield the greatest amount of energy for the cell when metabolized by mitochondria. A possible hypothesis of this experiment will be that: IF a yeast cell is supplied with maltose sugar, THEN it would yield the greatest amount of energy when metabolized by bacteria
Note that, this hypothesis must be testable by conducting an experiment and it doesn't have to be true. It can be disproved or proved by the outcome of the experiment. In this case, the hypothesis is giving an educated guess that maltose is the sugar that will yield the greatest amount of energy for yeast cells

Rachel wants to test how sunlight impacts plant growth over time she will add billing amount of light to different sets of plans what is the independent variable
Answer: sunlight.
Explanation: When trying to establish the level or extent of correlation or relationship which exists between two variables, the variables are classed as independent and dependent variables. The independent variable is referred to as the variable which causes a change in the value of the other variable (dependent variable). It is also known as the explanatory or predictor variable as it lead to changes in the dependent or predicted variable. In the scenario above, the independent variable is sunlight whose impact leads to changes in the growth level of the plant.

All pros when conducting a lab experiment except?
a) the scientist can manipulate variables
b) the scientist can control all of the variables
Answer:
I personally believe that lab experiments are useful and an effective way to test and gather data. Even though they can often lack ecological validity and mundane realism they can easily be replicated and results can be retested, helping to prove/disprove data, ultimately leading to the creation of practical applications.
That psychologist can make statements about cause and effect because they involve the deliberate manipulation of one variable while trying to keep the other variables constant, unlike non-experimental methods.Lab experiments can also be replicated due to the standardised procedures and measures, ultimately making it easier to check the reliability of the research/results and prove/disprove results if the research is conducted by another researcher.
