Answer:
Passive transport
Explanation:
Diffusion is a passive mechanism of transport. Until the concentration is the same throughout the space, a single substance has a tendency to travel from an area of high concentration to an area of low concentration. You are aware of how compounds diffuse through the air.
What are the passive transport dynamic equilibrium?Chemicals move passively from a location of higher concentration to a region of lower concentration through a process called diffusion.
We discussed three passive transport techniques: osmosis, assisted diffusion, and diffusion, all of which are crucial for cellular operations. Although the precise mechanics powering each of these transportation strategies vary, they are all non-energetic.
Therefore, Passive transport is a phenomenon that happens naturally and doesn't require the cell to use energy to move.

La respuesta correcta es "a. arterias, b. venas; y c. capilares".
Explanation:
Los vasos sanguíneos son una serie de conductos a través de los cuales el cuerpo transporta la sangre, asegurando que todas las células del cuerpo tenga acceso a oxígeno, elemento necesario para la respiración celular. Hay tres tipos de vasos sanguíneos: arterias, venas y capilares. Las arterias llevan la sangre del corazón a los órganos, las venas transportan la sangre de los órganos al corazón y los capilares son vasos muy pequeñitos que llegan a las partes más pequeñas del cuerpo.

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.

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.

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.

An amoeba is a unicellular organism, which doesn’t have a stomach for digestion of food. How does food storage and digestion take place in an amoeba?
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.
