Having too much matter causes the star to explode, resulting in a supernova. As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova
Answer:
You have the right answer, its B.
Explanation:
Option (B) single-celled organisms, and multicelled organisms are the correct answer.
Protists represent an important evolutionary step between single-celled organisms and multi-celled organisms.
<h3>
What are Protists?</h3>
- Protists are eukaryotes because they have a nucleus and other organelles that are attached to membranes.
- Protists have a distinctive central compartment termed the nucleus, which is shared by all eukaryotic cells and contains their genetic material.
- Organelles, specialized pieces of cellular machinery, carry out specific tasks within the cell.
- Plastids are found in photosynthetic protists like numerous kinds of algae.
- Protists' DNA resembles that of cyanobacteria.
- Cyanobacteria are single-celled organisms, whereas algae are multi-celled organisms.
We can infer from this debate that protists are a crucial evolutionary step between single-celled organisms and multi-celled organisms as they share many characteristics with both cyanobacteria and algae.

A red blood cell placed in water will swell and burst due to osmosis. Osmosis happens when water moves to an area of higher concentration to an area of lower concentration. Since the inside of a red blood cell has less pressure than the water exerts on the cell, it will cause the cell to expand and then burst.
