Answer: What Is a Real Hypothesis?
A hypothesis is a tentative statement that proposes a possible explanation to some phenomenon or event. A useful hypothesis is a testable statement, which may include a prediction. A hypothesis should not be confused with a theory. Theories are general explanations based on a large amount of data. For example, the theory of evolution applies to all living things and is based on wide range of observations. However, there are many things about evolution that are not fully understood such as gaps in the fossil record. Many hypotheses have been proposed and tested.
When Are Hypotheses Used?
The key word is testable. That is, you will perform a test of how two variables might be related. This is when you are doing a real experiment. You are testing variables. Usually, a hypothesis is based on some previous observation such as noticing that in November many trees undergo color changes in their leaves and the average daily temperatures are dropping. Are these two events connected? How?
Any laboratory procedure you follow without a hypothesis is really not an experiment. It is just an exercise or demonstration of what is already known.
How Are Hypotheses Written?
Chocolate may cause pimples.
Salt in soil may affect plant growth.
Plant growth may be affected by the color of the light.
Bacterial growth may be affected by temperature.
Ultra violet light may cause skin cancer.
Temperature may cause leaves to change color.
All of these are examples of hypotheses because they use the tentative word "may”. However, their form is not particularly useful. Using the word “may” does not suggest how you would go about providing supporting evidence for the hypothesis. If these statements had not been written carefully, they may not have even been hypotheses at all. For example, if we say "Trees will change color when it gets cold." we are making a prediction. Or if we write, "Ultraviolet light causes skin cancer." could be a conclusion. One way to prevent making such easy mistakes is to formalize the form of the hypothesis.

Photosynthesis and cellular respiration form a cycle. A cycle is a sequence of events that repeats itself over and over again.
In your own words, explain how photosynthesis and cellular respiration form a cycle. Include details about the organisms that perform photosynthesis and cellular respiration, and the materials involved.
Your response should be at least 3 sentences long.
Answer:
Photosynthesis changes over carbon dioxide and water into oxygen and glucose. Glucose is utilized as food by the plant and oxygen is a result. Cell breath changes over oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are side-effects and ATP is energy that is changed from the cycle.

why is starch not absorbed in the small intestine

which kind of soil is likely to have the HIGHEST porosity? A) Soil that is a mixture of sand and clay. B) soil that is all clay. C) soil that is a mixture of silt and clay. D) soil that is all sand.
Explanation:
Sand have the largest particle size so it has the highest porosity.
The answer is Soil that is all sand (D).
Soil that is all sand is likely to have the HIGHEST porosity. Therefore option D is correct.
Porosity refers to the amount of empty space or voids within a soil or rock. It is a measure of how much water or air can be stored in the soil. The type and arrangement of soil particles greatly influence porosity.
Sand particles are relatively large and have larger spaces between them compared to clay or silt particles. This means that sand has a higher porosity because it has more empty spaces or voids that can hold water and air.
The larger particle size allows for better drainage and easier movement of water and air through the soil.
In contrast, clay particles are much smaller and tightly packed together, resulting in smaller spaces between them. This compact arrangement reduces the porosity of clay soils, making it harder for water and air to penetrate and move through the soil.
Soil that is a mixture of sand and clay may have a moderate porosity, as the sand particles contribute to higher porosity while the clay particles reduce it to some extent. Similarly, soil that is a mixture of silt and clay may also have moderate porosity.
Therefore, if we consider the given options, soil that is all sand is likely to have the highest porosity due to the larger particle size and the resulting larger spaces or voids between the sand particles.

Which student correctly identified the geological process that formed Himilayan mountains?
Answer:
Student 2 is correct!
Explanation:
The Himalayas, which stretch over 2400 km between the Namcha Barwa syntaxis in Tibet and the Nanga Parbat syntaxis in Kashmir, are the result of an ongoing orogeny — the result of a collision of the continental crust of two tectonic plates. This immense mountain range was formed by tectonic forces and sculpted by weathering and erosion.
The geological events include the formation of the mountains. Student 2, stated about the collision of the continental plates. Thus, option A is correct.
What are continental plates?Continental plates are the plate tectonics that is found between the crust and the mantle of the earth (lithosphere). The continental plates are said to have less density than the oceanic plates. This results in the formation of the elevation unlike the depression in oceans.
The converging of the continental plates resulting from collision causes the crust to uplift and form the Himalayan mountains. The tectonic plate of the continents melts, slides, and falls against each other to form the elevated structure.
Therefore, option A. student 2 correctly explained the Himalayan mountain formation.
