Explain the fluid mosaic model
MrRa [10]
The model describes how cellular membranes i.e. lipid bilayers are organized. Despite the fluidity, lipid bilayers can form certain domains with different characterisrics and compositions. The cell can use different mixtures of lipids to create a 'mosaic' or 'patchwork' of domains.
An example of such domains are so called 'lipid rafts' which are aggregates of certain lipids (mostly cholesterol and sphingomyelins). In these rafts the lateral diffusion of membrane-bound proteins is strongly reduced, thereby forming stable complexes to facilitate, for example, signal-processing and transduction.
Note that a lot about how or why a cell creates these domains is still unknown.

Which of the following are some examples of rapid environmental changes? Please select all that apply.
Stolb23 [73]

Answer:

fire

landslide

avalanche

Explanation:

Fire, landslides, and avalanches are the examples of rapid environmental changes because they are able to destroy or affect the structure of living organism in a particular area. For example, fires can destroy all forms of life within days. A recent event of wildfire in Austria killed more than 1 billion of animals. Similarly, landslides and avalanche are geological calamities that are caused by the movement of a large mass of rock debris or snow moving downhill. The living organisms living there would be killed and this process can diminsh many forms of life (multicellular eukaryotes) rapidly.

On the other hand, (ecological) succession is a very slow process that results into change or disappearance of living organisms or particular species or ecological community in an area. This process can take place over decadaes, thousands or million of years. It can also lead to the species extinction as well.

Such antimicrobials exhibit a range of cellular targets, the ____________ selective being the most effective against the widest
Inessa [10]

Answer:

least, most

Explanation:

Antimicrobials are substances that function by limiting the activities of microorganisms either by killing them or by inhibiting their growths.

Antimicrobials that exhibit a wide range of cellular targets are least selective of the type of cells they kill or inhibit. They are also said to have a wide spectrum of activities.

On the other hand, antimicrobials that exhibit a narrow range of cellular targets are most selective of the type of cells they kill or inhibit. They are said to have a narrow spectrum of activities.

Describe the structure and function of a root hair cell
Nadya [2.5K]
Root hair cells absorb minerals and water from the soil.


The water absorbed by the root hair cells passes through the plant in xylem tubes, to then reach the leaves. The energy from the sun is then used to convert water(H2O) into hydrogen (H) and oxygen(O2).
