Phospholipids have phosphate group heads that are hydrophilic while the fatty acid tails are hydrophobic.
They are able to form cell membrane as they automatically arrange themselves in the required pattern in water because of these properties.To form membranes, these line up next to each other with their heads on the outside of the cell and their tails on the inside. A second layer of phospholipids also forms with heads on the inside of the cell and tails facing away.
In this way a double layer is formed with phosphate group heads on the outside, and fatty acid tails on the inside. This double layer, called a lipid bi-layer, forms the main part of the cell membrane.
The answer would be 14.50
Answer:
Effects of nutrient additions/changes in resources to microbial
scale
Explanation:
Addition of nutrient at microbial scale level affects ecosystem processes by multiplying the growth of such microbes, as well as result in producing more resistant species that are capable of creating a sustainability system for other content of the ecosystem.
While on the other hand, change in the resources of the microbial scale could either result to a modification of their adaptability structure in terms of physiological and biochemical composition, or an inhibition of the microbial population in the ecosystem.
Answer:
Hypothesis, controlled conditions, "if then" statement, scientific investigation, observation.
Explanation:
Hypothesis: An idea proposed for an argument to be tested if it's true.
Controlled Conditions: An experiment that doesn't manipulate the independent variable.
If then statements: These sentences present situations and their outcomes.
Scientific Investigation: A plan for asking questions and testing possible answers.
Observation: Using one of the senses (hearing, seeing, tasting, smell, touching) or measurements to gather data.
Let me know if you need more!
The blood pressure in the arteries are fast paced so the arteries would need to be strong in order to manage while the blood pressure in the vains are much slower so the are not really strong builded
hope this helped
