By interacting with the external environment, if you mean how molecules are transported outside and into the cell then there are 3 main ways of transport.
Passive transport which refers to the movement of molecules into the cell without using any energy. This includes osmosis (movement of water), diffusion (movement of small molecules like salt) and facilitated diffusion which is the movement of large molecules such as glucose via by channels on the plasma membrane.
Note, in diffuson the cell wants equilibrium which means that the cell wants the same ratio of a specific type of molecule compared to the external envionrment. In other words, it's like a a very salty cell becoming less salty because the external envionrment is less salty.
Active transport refers to the movement of molecules against the concentration gradient using energy.
Bulk transport which refers to the movement of molecules that is influenced by the plasma membrane. One of the ways is for the plasma membrane to engulf particles or expel particles. This allows cells to remove waste.

Answer:
The correct answer will be option-Parallel processing
Explanation:
Parallel processing is the ability of the brain in which the brain processes the incoming stimuli of the different quality at the same time or simultaneously.
During the vision, the brain processes different stimuli at the same time like the shape, intensity, color and their spatial arrangement by different parts of the brain individually and then analyzing and comparing the stimuli to the stored memories. This parallel processing helps the brain to identify the vision.
Thus, parallel processing is the correct answer.
Answer:
Glaciers cause erosion as they melt, carrying sediment that gets deposited in a thick layer.
Explanation:
Moraine refers to glacially formed debris (which could be regolith or rock) that occurs when glaciated regions on Earth undergoes a geomorphological process.
Moraine enables the Glaciers cause erosion as they melt, carrying sediment that gets deposited in a thick layer.
Answer:
Compounds needed for electron Transport chain are;
NADH
FADH2
NAD+
FAD
O2
H2o
Compounds that are produced are
ADP
ATP
Explanation:
Electron transport chain is a biological process that produced ATP in the body cells which entails building proton motive force that produce ATP.
The main electron transport chain electron donors are succinate and nicotinamide adenine dinucleotide hydrate (NADH).
nicotinamide adenine dinucleotide (NAD+) fuse with a proton to form NADH at the mitochondrial matrix.
flavin adenine dinucleotide (FADH2) plays a similar role as an electron donor.
Molecules such as pyruvate and succinate release energy when they are burned in the oxygen. This oxygen is later reduced to water.
The precursors of ATP, adenosine diphosphate (ADP) and inorganic phosphate (Pi) are transported nto the mitochondrial matrix which later bond to form ATP.
