Answer: Independent variable is what is being modified, it is important to compare it to your control group, (which is the original).

Dependent variable is what is being measured, to compare it to the control group to see if your hypothesis works or not.

Explanation: Here's a(n) example:

Bob wanted to take a mint with a mint drop, and he wanted to measure if it can make his breath fresher, but he also wanted to take it with a regular mint to see which is the freshest breath.

Independent variable: Mint drop.

Dependent Variable: Breath (To see if it is going to change with a mint drop.)

Control Group- Regular mint.

Which of the following is NOT one of the Nervous System Functions?. Single choice.
Neko [114]

Answer:

4. Absorb extra fluid between the cells

Explanation:

The nervous system (SN) is a complex system that acts to receive sensory information through nerves, transmit this information via the spinal cord and finally process it in the brain. The SN has three main roles: sensory input, processing and motor output. The SN can be divided into the central nervous system (composed of the brain and spinal cord), and the peripheral nervous system (composed of those nerves located outside the brain and spinal cord). Moreover, the extracellular fluid between the cells comprises four types of fluids: 1-intravascular fluid (blood), 2-interstitial fluid, 3--transcellular fluid and 4-cerebrospinal fluid. The excess of these fluids is absorbed by the capillaries of the lymphatic system.

1. Why are new biomedical products created and what factors influence them to evolve over
Zanzabum

Answer:

Rapid progress in biomedical science has also encouraged the development of multiple successful medical technologies, but their translation into clinical use has posed complex scientific, cultural, and social problems. As demonstrated by the development of new acquired immune deficiency syndrome (AIDS) medications, the rise of these problems is spurring new interest in medical innovation.

Biomedical products are created for better results in medical technology including autoclave / sterilizer, anesthesia machine, aspiration/suction pump, and blood chemistry analyzer etcetra.

Factors influencing them includes harmful effect on other body parts ( beta blockers have harmful effect on heart), outdating technology, and introduction of evolved diseases that is not abl to cure with old products.
