Answer:
Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance.

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

Describe how the EMG signal (a voltage) arises from muscle activity
Answer: The EMG signal is a biomedical signal that measures electrical currents generated in muscles during its contraction representing neuromuscular activities. The nervous system always controls the muscle activity (contraction/relaxation). ... EMG signal acquires noise while traveling through different tissues. EMG signals are recorded by placing electrodes close to the muscle groups. When the muscle is activated, the length of the muscle decreases and the muscle, skin and electrodes move with respect to one another. At that time, the electrodes will show some movement artifacts
Explanation:
EMG signals are recorded by positioning electrodes close to the muscle groups. It is the arrangement that helps in the monitoring of EMG signals from muscle activity.
What do you mean by EMG signals?EMG signals may be defined as a biomedical signal that estimates electrical currents provoked in muscles during their contraction illustrating neuromuscular activities.
When the muscle is stimulated for any mechanism, the length of the muscle declines, which leads to the muscle, skin, and electrodes moving with regard to one another.
The EMG signals always arise from the electrical activity of the muscle fibers which are stimulated during the time of contraction.
Therefore, EMG signals are recorded by positioning electrodes close to the muscle groups. It is the arrangement that helps in the monitoring of EMG signals from muscle activity.

You've been experiencing acid indigestion lately, and you'd like a quick fix for the problem. You do a little research on the Internet and discover that your problem is caused by excess stomach acid. In the pharmacy aisles, however, you're having a little trouble deciding what to purchase to address the problem. At the pharmacy counter, the clerk recommends that you purchase PEPCID AC or Alka-Seltzer tablets. You want to design an experiment to compare the effectiveness of Pepcid AC tablets and Alka-Seltzer tablets. Which of the following facts would be least likely to complicate your experiment and the analysis of your results?
a. PEPCIO AC and Alka-Seitzer tablets contain different ingredients.
b. PEPCID AC and Alka Seltzer tablets contain different concentrations of the antacid drug.
c. The recommended dosage for PEPCID AC and Alka-Seltzer tablets is different.
d. PEPCIO AC and Alka-Seltzer tablets are sold in different countries throughout the world,
Answer:
d. PEPCIO AC and Alka-Seltzer tablets are sold in different countries throughout the world.
Explanation:
When there is excess acid in the stomach then Alka-Seltzer tablet can be used. The Ph level of these tablets is higher than 7 because acidic reaction need to be stopped with an introduction of base.
If all of your cells have the same complete set of DNA why do different cells in different proteins
Why do we have different cells in our bodies if every cell has the same DNA?
The genome of a cell contains in its DNA sequence the information to make many thousands of different protein and RNA molecules. A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed.
Where does ocean salt come from?
a. macrofungi
b. sporophere
c. roomology
d. mycology
Ocean salt primarily comes from the evaporation of seawater, leaving behind the dissolved minerals and salts. It is not derived from macrofungi, sporophere, roomology, or mycology.
Ocean water contains dissolved salts and minerals, which are primarily derived from various sources such as weathering of rocks on land, volcanic activity, and underwater vents.
When the sun's energy heats the surface of the ocean, it causes the water to evaporate. Evaporation is the process by which water molecules escape into the atmosphere as water vapor.As the water vapor rises, it leaves behind the dissolved salts and minerals, which become concentrated in the remaining seawater.Over time, with continued evaporation, the concentration of salts and minerals in the remaining water increases.Eventually, the remaining water becomes supersaturated with salts, leading to the formation of salt crystals. These crystals can take the form of various salt compounds, such as sodium chloride (common table salt) and others.These salt crystals may precipitate and settle at the bottom of the ocean or accumulate in saltwater bodies, such as salt flats or salt pans.Therefore, ocean salt is primarily a result of the evaporation of seawater, concentrating and leaving behind dissolved salts and minerals. It is not derived from macrofungi, sporophere, roomology, or mycology.

which of the following is an example of a complementary base pair in DNA?
a. A-G
b. T-C
c. A-U
d. C-G
Answer: d. C-G
Explanation:
DNA or deoxyribonucleic acid is a structure which is common in every living organism. The two strands of the DNA are held together by base complementarity between the nitrogenous bases these bases are held by hydrogen bonding. Adenine always pairs with thymine by a triple hydrogen bonding and cytosine is always forms a pair with that of guanine by a double hydrogen bonding. So, in this given situation cytosine or C will show complementarity with that of guanine or G in a DNA structure helping in linking the two strands of DNA to form a single integrated double helical structure.
