Answer:
The mechanisms of transport across the cell membrane are as follow: 1- simple diffusion, 2- facilitated diffusion, 3- primary active transport and 4-secondary active transport
Explanation:
The cell membrane is a selectively permeable structure capable of transporting substances by different mechanisms. Simple diffusion is a type of passive transport (i.e. does not require energy) where non-polar molecules (e.g. O2, CO2) pass across the membrane by a process that does not require energy from the cell. Facilitated diffusion is another type of passive transport where larger polar molecules (e.g., glucose and amino acids) pass across the membrane by using specific transmembrane integral proteins. On the other hand, primary active transport is a type of active transport that uses chemical energy (e.g., ATP) to move substances such as metal ions (Na+, K+, Ca2+) across the cell membrane against their concentration gradient. Finally, secondary active transport is another type of active transport where transporter proteins are used to couple the movement of ions (e.g., H+ protons) down their electrochemical gradient to the transport of another ions/solutes against their concentration/ electrochemical gradient.

The kingdom is Animals.
The genus is Haliaeetus.
The species is leucocephalus are the statements which Julio can make about the bald eagle.
The option C is the correct answer.
Explanation:
Given that Bald eagle has binomial name as Haliaeetus leucocephalus.
Modern classification of binomial nomenclature is given by Carl Linnaeus.
From the modern system of classification the sequence is as kingdom, phylum, class, order, family, genus and species. The classification of bald eagle is:
Kingdom - Animalia
Phylum - chordata
class - Aves
Order- Accipitriformes
family - Accipitridae
Genus - Haliaeetus
species - leucocephalus.
The two word name of the species having genus first followed by species is binomial nomenclature which Julio has used for bald eagle as Haliaeetus leucocephalus.
