MrMuchimi

the correct answer is A- Reproductive isolation occurred through behavioral isolation

A process of formation of a new species from an existing species is called speciation. New species may formed due to geographical or reproductive barriers which isolates the members of a population of a species to form a new species.

In the given question, speciation in In the leopard frogs occurred due to a particular or specific call given by males to the females. The courtship call lead to reproductive isolation due to change in behavior. Such type of behavioral change will help in recognizing mates of the same species and this will act as a reproductive barrier among the other related species.

Olenka [21]

Answer:

A. Populations of native wetlands plants will recolonize the land.

Explanation:

From many years' wetlands are converted into farmlands as they provide retention of soil, proper food and clean water, and the cycling of nutrients. But wetlands should not be permanently converted because it can increase the load on soil and add pollutants (pesticides or fertilizers) in the soil and groundwater.

If the farming stops and water flows on the land again, the native plants present in wetlands will help to recolonize the land which is disrupted by farming activities.

Hence, the correct option is A.

Bioflix activity: membrane transport -- vocabulary review can you match the processes involved in membrane transport to their de

Natalka [10]

Explanation:

From the diagram with corresponding labels:

Exocytosis
Facilitated diffusion
Endocytosis
Diffusion
Active transport

Further explanation:

Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid by layer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Active transport is a mediated process that requires the use of specialized membrane proteins these proteins require energy in the form of avenues and triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules.

Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane. Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane, from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion

...some very large molecules require specialized type of active transport in order to move across the membrane this includes endocytosis and exocytosis

During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of invagination; piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule this breaks off from the membrane to form an intracellular vesicle; different methods of endocytosis such as Phagocytosis, Pinocytosis and receptor-mediated endocytosis, take in cells, water and targeted substances respectively.

Similarly, in exocytosis, the particles (Protein, Waste material etc.) surrounded by a phospholipid membrane. However, this membrane is formed in the cytoplasm, and attaches to the plasma membrane’s interior in a process opposite to endocytosis; material is removed from the cell and exported into the cell’s exterior called the extracellular space.
