Answer:
The correct answer is D
Explanation:
The cell membrane is essentially composed of the following:
- phospholipids
- cholesterol
- proteins
The phospholipid consists of a <em>hydrophilic </em>phosphate 'head' and the tail is the <em>hydrophobic</em> fatty acid chain.When cellular membranes form,phospholipids collect into two layers in light of these hydrophilic and hydrophobic properties. The phosphate heads in each layer face the fluid or watery condition on either side, and the tails conceal away from the water between the layers of heads, since they are hydrophobic.
There are 3 main factors that greatly influence the fluidity of the plasma membrane:
- temperature
- cholesterol
- saturated and unsaturated fatty acids
Answer:
Large areas of the earth with similar climate and ecosystems are called biomes.
Explanation:
Biomes are defined as areas of the planet with common characteristics, such as animal and plant species, as well as climate, which is why it is called a bioclimatic landscape.
When a relationship is established between an ecosystem —with all its biotic and abiotic components— and the climate in a given area, reference is made to a biome. Consequently, a <u>biome represents large areas of land with similar geographical, climatic and biological conditions</u>.
The other options are not correct because:
- <u><em>Communities</em></u><em> are groups of individuals with common characteristics.
</em>
- <u><em>Populations</em></u><em> are individuals of the same species that occupy a certain space in a certain time.
</em>
- <u><em>Organisms</em></u><em> are synonymous with living beings.</em>
Fatty acid tails = hydrophobic
Phosphate heads= hydrophilic
Explanation:
Looking at the Ecological concept of Modern Ecology
we have
Atmosphere, Lithosphere, Biosphere, Niche, Environment, Habitat, Population, Ecosystem and Biotic community
Hydrosphere and Geosphere are not part
so Atmosphere is the correct answer
