Explain the relationship between a hypothesis and a theory. Then give an example of something that would cause a hypothesis or a theory to be revised or discarded.
Answers
Answer:
Hypothesis is a written observation, that has not been proven correct, but is written after observation of a specimen. Proving this particular hypothesis, shows the interconnectivity/ relationship between a hypothesis and a theory.
Explanation:
Simply put, a hypothesis is a written observation, which may or may not be true, while a theory is established when a hypothesis is proven correct.
AN EXAMPLE OF SOMETHING THAT COULD MAKE A THEORY TO BE REVISED:
If other laws or theories put before it controversies it.If its observations where not correctly written.If it cannot stand the test of time.If further experiments doesn't show the same result.Hypothesis is either written or evidence based observation but it has to be proven where as when a hypothesis is proved by doing experiments multiple times and getting same results then it is called as as scientific theory.
What is scientific theory ?scientific theory can be a structured form where a group of facts can meet and be explained by using scientific hypothesis and laws, each theory can be proved by doing experiments and applying scientific method.
Scientist will design an experiment and conduct the experiment to test and prove that hypothesis; If the result of hypothesis is incorrect, then new hypothesis will be set and new experiment will begin.
If the result of hypothesis is correct, repeated tests have been done to ensure the accuracy of the result.

A. Homologous structures
B. Analogous structures
C. Vestigial structures
D. Embryo development
Answers
Answer:
Answer is A, Homologous Structures
Explanation:
The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants are classified as Homologous structures. Option A is correct.
Homologous structures:
These are the structures in the different organisms that show similarities in the basic organization of the structure.
These organisms are from common ancestors, Homologous structures serve completely different functions.For example- The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants.Analogous structures are those structures that serve the same function but are from different ancestors.
Therefore, The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants are classified as Homologous structures.

where is sugar removed and how can you tell
Answers
Explanation:
What you need to understand first, is the digestive system, after that, you'll probably be able to understand not only sugar, but other components of your food too.
It all starts at your mouth, you are going to do a lot of the job for the food to get to your stomach by chewing it. After it gets to your stomach, the digestion will do its job as the pH there is less than 7. After this process, the food is going to your intestine, and then, it's right here, that the sugar/carbohydrates you ate are going to get into your blood. After this, sugar is going to be used to create energy for your cells and body to work properly, with that, sugar is consumed and you can start the process all over again.

C. True in all elements, it maintains its properties even after it combines with
other elements.
D. True to all elements, they have the properties after they are combined.
The correct option is D.
True to all elements, they have the properties after they are combined.
Explanation:
Elements are pure substances which can not be divide by any form of chemical means.
True to all elements, they have the properties after they are ccombine because elements contain atoms and atoms is the smallest indivisible units which retain chemical properties because chemical bonds are formed between the atoms of elements.

Which type of energy change causes this leaf to grow? A. Thermal energy is transformed into potential energy. B. Thermal energy is transferred to the leaf. C. Electromagnetic energy is transformed into chemical energy. D. Electromagnetic energy is transferred to the leaf.
Answers
Answer:
C. Electromagnetic energy is transformed into chemical energy
Explanation:
Growth is one of the characteristics of living things. It refers to the increase of an organism. A leaf is part of a plant, which is a photosynthetic organism i.e. an organism capable of producing its own food using energy from sunlight. Light energy is a part of the ELECTROMAGNETIC ENERGY.
This light energy is used to synthesize glucose (food) via photosynthesis. The glucose, which stores chemical energy in its bond is then broken down to yield ATP used for growth. Hence, the transformation of electromagnetic energy to light energy is how a leaf grow.
it is C. Electromagnetic energy is transformed into chemical energy.

Mr. Chavez wants his class to prepare a procedure that would demonstrate cellular diffusion. Which of the following procedures would best demonstrate cellular osmosis?
A. A procedure that uses the skins of potato left overnight in oil
B. A procedure that uses a cluster of grapes left overnight in a high concentration of salt water
C. A procedure that uses a 2-liter bottle filled with oil and water and left overnight
D.A procedure that uses a banana that has been left overnight in milk
Answers
Answer:
B
Explanation:
The second option correctly shows the process of cellular osmosis.
When the grapes would be immersed in water, the molecules of water move across the cell membrane from the region of low to high solute concentration. Due to this, the water would leave the cells and diffusion of water from the cells of the grapes. Thus, option B is the correct answer.
In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).
Osmosis refers to the movement of a solution (often water) across a selectively permeable membrane.This movement (osmosis) is due to the difference in solute concentrations on both sides of the semipermeable membrane.In osmosis, water molecules move from a region of low concentration of solutes (e.g., salt) to a region of high concentration of solutes.
In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).
