It gives the plant air and food
Answer:
The answer (Image 1) is attached. Since the options weren't provided, I've attached the image of the options, too.
Explanation:
The plasma membrane is composed of phospholipids, a special form of lipids with a hydrophilic head and hydrophobic tail. According to the fluid mosaic model, the hydrophilic heads are positioned towards the outside where they freely interact with the extracellular matrix and cytosol. Whereas, the hydrophobic tails are positioned towards the inside so they aren't exposed to water.
Liposomes are lipid bases particles used for drug and vector delivery. The picture shows a typical liposome.
In the current case, for water to move both outside and inside, hydrophilic heads should be present inside as well as outside the tails.
The livers have a good day! :))
33% is the unknown concentration of the tube.
Explanation:
Concentration of stock of windex = 50%
concentration of bacteria = 500 microliter
nutrient broth = 1000 micro litre +500 microlitre of windex
concentration of bacteria is the volume of bacteria present in nutrient broth culture.
total volume in the tube is 1000
50% is the concentration of tube of bacteria and broth before adding windex.
After adding windex of 50 % concentration and the volume is 500 microliter which is only 250 microliter of windex rest is water.
33% is the concentration of the tube, which means it has 33% of bacteria in 1500 ml of solution.
The answer is different magnification lenses. Leeuwenhoek use a microscope with different magnification lenses which enabled him to see bacteria. <span>His microscope was able to achieve 50-300x magnification, which enabled him to see a variety of bacteria.</span>
