Answer:

A scientific hypothesis is the initial building block in the scientific method. Many describe it as an "educated guess," based on prior knowledge and observation. ... A hypothesis also includes an explanation of why the guess may be correct, according to National Science Teachers Association.

Answer:

Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing

The basic idea of a hypothesis is that there is no pre-determined outcome. ... A key function in this step in the scientific method is deriving predictions from the hypotheses about the results of future experiments, and then performing those experiments to see whether they support the predictions

Mumz [18]

I would say A, because if a person was not digesting food properly a high concentration of unabsorbed nutrients in your intestines prompts an influx of water, which would also lead to diarrhea.

PLEASE ANSWER QUICKLY Which statement about cell theory is INCORRECT? New cells are spontaneously created from existing cells. A
Mazyrski [523]

Answer:

New cells are spontaneously created from existing cells

Explanation:

In the 1830's, three scientists namely: Matthias Schleiden (a botanist), Theodor Schwann (a zoologist) and Rudolf Virchow proposed the Unified cell theory. In this theory, three parts were universally accepted and they are as follows:

1) Cells are the fundamental and basic unit of all life and structure.

2) All living organisms are made up of one or more of these cells.

3) New cells arise from already pre-existing cells.

These three parts are the widely accepted parts of the cell theory. Although, it was once believed that new cells arose from inorganic matter. This theory, called spontaneous generation or abiogenesis was later disapproved.

Therefore, the statement that, "new cells are spontaneously created from existing cells" is not a part of the CELL THEORY.

postnew [5]

Answer:

The process shown in the model requires energy from the cell.

Explanation:

Active transport refers to the movement of materials across the cell membrane against concentration gradient.

The cell membrane remains intact. However, energy is required from within the cell to move materials into the cell against concentration gradient, hence the answer.

Which best exemplifies the concept of neuroplasticity?
KonstantinChe [14]
The correct answer is "the formation of new brain cell connections as the result of reading a book".

Usually, neuroplasticity is apparent in young children when the central nervous system has an abundance of neurons. This is always in the context of forming new brain cell connections or synapses that will lead the person to access the information quicker. This also exemplifies the principle of use and disuse when it comes to knowledge. 

The other choices concerns the skeletal system, cardiovascular system, and the endocrine/reproductive system; all of which do not have a relation with neuroplasticity.
