Answers

Answer:

The most appropriate answer would be A. Characteristics of “place” include things like economic activity, architecture, and culture, all of which are human elements that alter or can be influenced by the environment.

The place can be defined as the geographical area in which humans are living. Different places can have different characteristics such as economic activity, culture, architecture, employment et cetera.

These characteristics are largely influenced by the environment. For example, a natural disaster can change the financial status of any place.

These characteristics majorly determine the movement of humans from one place to another. For example, many people move to urban areas from rural areas for better opportunities, lifestyle et cetera.

A lysosome containing digestive enzymes then fuses with the vesicle. Which term best classifies the uptake of such particles by the cell? simple diffusion endocytosis exocytosis osmosis

Answers

b.endocytosis. simple diffusion is a passive transport that doesn't require energy just like putting a dye on the litter of water and it moves to higher gradient into lower gardient .facilitated diffusion is a type of active transport w/ a barrier in it it requires energy to some biochemical through to pass it is kinda like osmosis but in osmosis it doesnt need energy to pass through it only acts as barrier it just like diffusion in diffusion it has no membrane.it acts the same principle from higher gradient to lower.

The Answer is b:

Endocytosis
