The polarity of the phospholipid makes it ideal for a building block of cell membranes.
Explanation:
There is the tails which are hydrophobic (water fearing) and the heads which are hydrophilic (water loving). These properties of phospholipids allow the tails to go towards eachother and heads to face the water which maintains a solid structure allowing certain materials to pass through.
Phospholipids are organic compounds that consist of two fatty acid hydrophobic tails and a phosphate hydrophilic head.
These properties help in the regulation of the cellular processes. The hydrophobic tails which is non polar doesn’t react with water while the hydrophilic heads help in interaction with water.
This helps in the movement of particles in and out of the cells and stratification of the cell membrane.
A. The complementary shapes of an enzyme and a substrate
Explanation:
The Lock-and-Key model was made to show how an enzyme's active zone fits a substrate and how they bond together. It correlates just like a lock and a key; you have to have the correct-shaped key in order to open a lock. Same process of thought with the enzymes; you must have the same shape for both in order to bind together,
The neural crest likely forms: neurons and glia of the peripheral nervous system
The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural tube
In the body region, neural crest cells also contribute the peripheral nervous system (both neurons and glia) consisting of sensory ganglia (dorsal root ganglia), sympathetic and parasympathetic ganglia and neural plexuses within specific tissues/organs
The nervous system is made up of specialized cells which includes nerve cells (or neurons) and glial cells (or glia)
Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances
Glia are also essential to nervous system function, but they work mostly by supporting the neurons
When the walleye pollock population decreased, there were more zooplankton available for the moon jellies to eat. Since the jellies had more energy storage molecules, they were able to reproduce more. This lead to more births than deaths in the moon jelly population, which caused the jelly population to increase.
