Answer:
The average diffusion distance is 2.1 mm
Explanation:
Given
Diffusion distance of the four potato squares are;
[tex]Potato 1: 2.1 mm\\Potato 2: 1.8 mm\\Potato 3: 2.3 mm\\Potato 4: 2.2 mm[/tex]
Required
Average Diffusion Distance
To calculate the average diffusion distance; we simply calculate the mean of the student recordings
Mean is calculated as thus;
[tex]Mean = \frac{\sum x}{n}[/tex]
Where x is the individual distance of the potato squares
[tex]\sum x = 2.1 mm + 1.8 mm + 2.3 mm + 2,2 mm[/tex]
[tex]\sum x = 8.4mm[/tex]
n is the number of potato squares
n = 4
[tex]Mean = \frac{\sum x}{n}[/tex]
[tex]Mean = \frac{8.4 mm}{4}[/tex]
[tex]Mean = 2.1 mm[/tex]
Hence, the average diffusion distance is 2.1mm

How do enzymes help digestion?
Answer:
Enzymes are essential for healthy digestion.
Explanation:
There are three types of digestive enzymes depending on the type of food on which they act.
Lipases are those that digest fat. After its breakdown into fatty acids and glycerin, they are synthesized by the pancreas.
Proteases are the ones that break the peptide bonds of proteins, reducing them to organic monomers called amino acids. They originate in the stomach or pancreas.
The so-called amylases break down starches and complex sugars in the diet, by breaking the glucidic bonds, releasing mososaccharides (especially glucose). There are 3 types of amylases: ptyaline, pancreatic amylase, and duodenal amylase.
The benefits of these enzymes are:
- They help digestion and reduce the so-called "acidity".
- They reduce the feeling of bloating and gas.
- Improves the digestion of dairy products.
- Food allergies decrease due to good protein digestion.
- They improve the conditions of hiatus hernia and ulcers.

What is the term for the breakdown of glucose in the presence of oxygen? cellular respiration photosynthesis anaerobic fermentation
Answer:
Cellular respiration
Explanation:
Cellular respiration involves the breakdown of glucose using oxygen to produce energy, or ATP, that is used by the cell.
The breakdown of glucose in the presence of oxygen is called as cellular respiration.
What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.
Moreover, it is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Hence, it is a series of chemical reactions that break down glucose to produce ATP.

Which movement of particles would be most affected by a disorder that causes damage to carrier proteins? osmosis passive transport active transport diffusion
Answer: Active Transport
Explanation: Active transport is the movement of a substance (proteins, enzymes, etc.) from one area of the cell membrane to the next during diffusion, so this would most be affected due to the kinds of substances being transported across the cell membrane and damage can have an impact.
Carrier proteins are involved in active transport. The movement of particles that would be most affected by a disorder that causes damage to carrier proteins is active transport. Option C.
What are the carrier proteins?Carrier proteins are transmembrane molecules involved in active transport.
They carry molecules from one side of the membrane to the other side.
What is active transport?Active transport acts against the electrochemical gradient, so it does need the energy to transport substances.
It carries molecules from a low concentration side to a high concentration side.
The used energy comes from ATP (Na-K bomb) or the membrane's electric potential.
The movement of particles that would be most affected by a disorder that causes damage to carrier proteins is active transport. Option C.

How would driving from Boston (near sea level) to summit of Mt. Washington affect the rate of oxygen exchange in your lungs? Explain in 1-2 sentences plz
Answer:
The rate of oxygen exchange in the lungs decreases, outstandingly while diving from Boston (near sea level) to summit of Mt. Washington
Explanation:
At near sea level, Boston, where there is sufficient dense air and plentiful supply of oxygen, the rate of breathing and oxygen exchange in the lungs is at normal levels
At the height of 6,288.2 feet, which is the height of the summit of Mt Washington, the lung does more work to extract the oxygen from the air present which is less dense and contains less oxygen than the air at sea level such that a larger volume of air is required to supply the amount of oxygen the body requires
Therefore, the rate of oxygen exchange in the lungs decreases, outstandingly while diving from Boston (near sea level) to summit of Mt. Washington.
Which biomolecule do you think is most important in your diet? Why did you pick that biomolecule? Which biomolecule do you think is most important in cell function? Nutrition and snack foods A. List your three favorite snack foods. B Collect a nutrition label from each food. C. If any of the foods on your list don’t come in a package, you can look up the nutrition information on the Internet. D. Write a paragraph about each food. Is it a good source of carbohydrates, lipids, and protein? Would you consider this food healthy? Why or why not? 2. You may have heard the saying, “You are what you eat.” to explain what this statement means.
Answer/Explanation:
There is no single biomolecule that is most important in one's diet; however, proteins would be a fitting choice. This is because there are certain amino acids -- 9 in fact -- that our bodies cannot naturally produce and of which proteins consist. We need these amino acids to survive because they make up proteins, and proteins perform pretty much every crucial function you can think of, ranging from defense to cell signaling to structure. All biomolecules are important in cell function -- carbs are needed for your cells to burn for energy via cellular respiration (a process that yields app. 28-32 ATPs per cycle), lipids are needed for cell membranes (amongst numerous other needs), proteins are needed for the reasons above, and nucleic acids are needed for RNA and DNA.
A. Welch's, Oreos, Chips Ahoy
B. You should be able to do this.
C. Proves my point in B.
D. Yeah, generally the snacks I chose are not healthy, even Welch's fruit snacks. It's junk food and not high in protein. "You are what you eat" makes sense in the quite literal sense because your body mass, your health, and your overall physical attributes are determined by your diet, on top of exercise and your activities throughout your life.

Name one disadvantage of light microscopes
Answer:
We can't examin the specimen in tbe absence of lght. We can not study the internal structures.
Explanation:
Answer:
Light microscopes do not magnify at the same level as other options.
The typical light microscope cannot magnify as closely as an electron microscope when looking at some of the world’s smallest structures. Most models are capped at 2,000 times or thereabouts, with some entry-level models offering significantly less to the user. Because the relatively long wavelength of light decreases the ability of the equipment to magnify in the small focus lens, you may not always see everything that is going on with a slide when choosing this option.

It was once thought that decaying meat turns into maggots. Careful experimentation by scientist demonstrated that maggots actually come from fly eggs and not meat. These experiments illustrate that the new individual results only from reproduction and development
Answer:
True
Explanation:
Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
It thus showed that new life does not arise spontaneously but rather through development and reproduction.

Answer:
P = 0.79.
Explanation:
To solve this, we need to understand the Hardy-Weinburg equation and what each variable is. P is usually used for the dominant trait classification (in this case, it would be long legs) and Q is usually used for the recessive trait classification (in this case, it would be short legs).
Therefore, we know that the values have to add up to 1 and that Q is recessive and P is dominant. So, if we begin applications, we can learn that to equal 1, we must use numbers less than 1 to accomplish this.
If 21 of a 100-person population have short legs, then ideally, 79 people would have long legs (the dominant trait). So, we know that 0.21 as q and 0.79 as p would equal 1 if you just added p and q together. Therefore, we can know that q is 0.21 and p is 0.79.
To prove this, we can insert these values into the equation:
[tex]0.79^{2} + 2(0.79*0.21) + 0.21^{2} =1[/tex]
[tex]0.6241 + 0.3318 + 0.0441 =1[/tex]
[tex]1=1[/tex]
