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.
Answer:
<em>The correct option is B) Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.</em>
Explanation:
Genetic continuity can be described as a fact that the daughter cells have the same amount and same type of genome as the parent cell. It includes the transfer of parental traits to children.
Binary fission can be described as a process of division which bacteria divides. Two daughter cells are produced as a result of binary fission. Each daughter cell is identical to the parent cell and hence maintains genetic continuity.
Answer:
the answer is D. None of the above.
In any ecosystem two factors interact together are abiotic factors and biotic factors. Abiotic factors include non-living such as soil, air, water and climatic factors ( temperature, humidity, rainfall or precipitation) whereas, biotic factors includes all the flora (plants) and fauna (animals). These two factors interact through food chains to function an ecosystem.
The correct answer is the second option. Animals have two major types: vertebrates and invertebrates. Vertebrates are animals that have backbone while the invertebrates do not have one. Examples for vertebrates are birds and mammals while the latter are insects and squid.
