There are differences between Eukaryotic and Prokaryotic cells. This difference is considered to be the most important distinction between groups of organisms. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. <span>Both plant and animal cells are eukaryotic cells.</span>
Answer:
pls what are the following examples always include them pls
The continuous, low-level extinction of species is referred to as mass extinction.
- A widespread and quick decline in the diversity of life on Earth is known as an extinction event.
- A sudden shift in the diversity and abundance of multicellular creatures serves as a telltale sign of such an occurrence. It happens when the rate of diversification outpaces the rate of extinction.
- A mass extinction event occurs when a species disappears far more quickly than it is replaced.
- This is typically understood as the loss of almost 75% of all species over a "short" period of geological time, or fewer than 2.8 million years.
- The Cretaceous-Paleogene extinction, sometimes known as the day the dinosaurs died, is the most well-known of all the mass extinction events.

Answer: The statement is true
Explanation:
The hypothalamus is part of the Fore-brain responsible for the secretion of hormones from the pituitary gland.
This pituitary gland situated in the hypothalamus is traditionally called the MASTER ENDOCRINE GLAND, as it influence the activities of all other glands such as thyroid gland.
Thus, the hypothalamus bearing the pituitary gland is said to be in CONTROL of the activity of the thyroid, and ALSO the master endocrine gland.
Answer:facilitated diffusion
Explanation: facilitated diffusion us the carrier-mediated Transport of large molecules across the cell membrane using Transport proteins found in the cell membrane.such molecules include glucose,amino acids and ions.the passage across the membrane is from higher concentration to lower concentration
