Answer: Lipid molecules.

Explanation: Biological membranes are bilayer of phospholipids that control the entrance and exit of molecules in the cells. The major components of phospholipids are the fatty acids. Phospholipids have two components: the fatty acyl chains and the phosphate group. The fatty acyl chains of the phospholipids molecules face each other at the core of the bilayer, forming a fluid hydrophobic interior while the phosphate (polar head) groups face outward. Proteins are embedded in this bilayer held by hydrophobic interactions between the membrane lipids and hydrophobic domains in the proteins. Both proteins and lipids move laterally in the plane of the bilayer but movement from one face of the bilayer to another is restricted.

inn [45]

Answer:

i think it would be A for wild fire, D for flood and E for Tsunami

Explanation: wild fire are one of the most common ways for a secondary succession that can bring change when the environment is disturbed or damaged. For instance, by allowing fast-growing plants to grow and provide a source of food and shelter for many animals to use and eventually draw them back into the ecosystem. Both flooding and tsunamis help push older organisms and other stuff from the environment to create for room for other plants and animals to come and keep the ecosystem healthy and ongoing.

Which terms below are associated with communication between neurons?

mixas84 [53]

Answer:

The correct answer is synapse, electrical signals, neurotransmitters.

Explanation:

Neuron communicates with other neurons via action potentials and chemical neurotransmitters through the synapse.

Two neurons form a junction that is termed as a synapse, there an action potential that results in neuron A to release a neurotransmitter (chemical).

Synapses are thought of as the site of converting an electrical signal into a neurotransmitter release which is a chemical signal.

Thus, the correct answer is synapse, electrical signals, neurotransmitters.
