Cell membranes have a number of ways that needed nutrients can pass through. The first and easiest way is by diffusion where certain particles are able to pass through the membrane directly where the are in short supply. Other particles, because they don't mix well with the lipids that make up the membrane can pass through certain protein channels in a process called facilitated diffusion. In a closely related process to diffusion where particles aren't able to cross the membrane but water can, osmosis takes place. Sometimes when cell need to move nutrients into already crowded areas they use energy in a process called active transport to kind force particles across the membrane where they don't want to go. A very special type of active transport called phagocytosis occurs when a cell wants to take in particles that are simply too large to pass through the membrane so the membrane actually stretches out and engulfs the particle in a vesicle where it can be dismantled into smaller components inside the cell. I hope that helps!
Jean-Baptiste Van Helmont is often credited with discovering that water alone could not provide all the nutrients needed for plant growth. This led to the concept of fertilizing water with nutrients to support plant growth.
All nutrients are essential for the body to function properly and maintain health. They provide energy, support growth and repair of tissues, and help regulate bodily processes. Nutrients can be obtained from food and are necessary for overall well-being.
The digestive system and the circulatory system are the two body systems most useful in getting nutrients. The digestive system breaks down food into smaller molecules, allowing nutrients to be absorbed in the intestines. Once absorbed, the circulatory system transports these nutrients throughout the body to cells and tissues where they are needed for energy, growth, and repair. Together, these systems ensure that the body receives the essential nutrients required for overall health.
Things like oxygen, CO2 and lipids cross the membrane with simple diffusion. Water can cross the membrane with osmosis when the water moves through a channel protein in the plasma membrane. Glucose, potassium, sodium etc. moves through a carrier protein in the membrane with the process of active movement. In the process of active movement energy is needed and it is given by the glucose or ATP from the cell.
A folded membrane increases the surface area available for absorption. More surface area allows for more sites for passive transport.
Nutrients needed for making hormones include healthy fats, proteins, and vitamins like B vitamins and vitamin D. For healthier skin, nutrients like vitamin C, vitamin E, zinc, and omega-3 fatty acids are important. To build a healthy cell membrane, nutrients such as phospholipids, fatty acids, and cholesterol are essential.
The large storage unit in a cell is the vacuole. Vacuoles are membrane-bound organelles responsible for storing various molecules, ions, and nutrients needed by the cell. They also help maintain turgor pressure and support the structural integrity of the cell.
The cell membrane will selectively absorb nutrients, water, and other molecules needed for the cell's function and survival. It also plays a role in regulating the intake of substances into the cell and expelling waste products out of the cell.

Storage nutrients are typically stored in specialized structures called vacuoles within the cell. These vacuoles can be found in various locations depending on the organism, such as in the cytoplasm or near the cell membrane. The storage nutrients can be accessed and utilized by the cell when needed for energy or other metabolic processes.
Some are: iron (needed to make red blood cells), calcium (needed to make bones and teeth), iodine (needed to make thyroid hormones), potassium and sodium (needed to operate cellular membrane pumps), sulfur (needed to make strong hair), phosphorus (needed for strong teeth), etc.

the cell membrane keeps the stuff needed inside the cell in, and the stuff needed outside the cell out
Martian soil does not have all the essential nutrients needed to support plant growth like Earth soil does. It lacks organic matter and some key elements such as nitrogen, phosphorus, and potassium. Specialized cultivation methods and supplementation would be required to support plant growth on Mars.
No they did not. It hurt the government because the US was not getting the supplies they needed from the foreign contries.
Detoxification isn't a really good option. A better solution would be to go vegetarian as you would be getting all your needed vitamins and nutrients.
