Answer:B, an introduced species is not necessarily harmful to the environment, an invasive species has a negative effect
Explanation:
Answer: A
Explanation:
"That's what evolution is all about: tiny changes in organisms of a species over a huge amount of time."
Answer:
<em>This is an example of natural selection (adaptation).</em>
Explanation:
Natural selection tends to favor those organisms which are better adapted to live in an environment.
As tortoises having flat shell and long neck were better adapted to live in barren area, hence through natural selection those organisms were favored in such an ecosystem.
As tortoises that lived on the vegetative lands were more adapted to live in such an ecosystem, hence through natural ecosystem these organisms were favored and increased in numbers.
Macromolecules or large particles are carried across the cell membrane via vesicles or other intracellular structures. Pinocytosis and efflux are the two types of vesicle transport.
<h3>How does a vesicle leave the cell with its cargo?</h3>
Exocytosis is the process by which cells move components from within the cell to the extracellular fluid. Exocytosis occurs when a vesicle's plasma membrane fuses with it, expelling its contents outside the cell.
The Golgi, also known as the Golgi complex, is a flattening, layered organelle that looks like a stack of pancakes. The Golgi body modifies and packages proteins and carbohydrates into lattice vesicles for "exportation" from the cell.
