Answer 1

Here are the answers to your questions:

**Question 1:**
**True**
A major difference between gram-positive and gram-negative bacteria is indeed the thickness of the peptidoglycan cell wall.

---

**Question 2:**
**False**
Bacteria and Archaea are not found in the same domain; they are classified into two separate domains: Bacteria and Archaea.

---

**Question 3:**
**Plasmids**
Plasmids are the tiny circular pieces of DNA that can be transferred between bacteria through horizontal gene transfer.

---

**Question 4:**
**True**
Carolus Linnaeus is known as the father of taxonomy for creating the Linnaean Classification system.

---

**Question 5:**
**Naja naja**
Based on the context of binomial nomenclature, "Naja naja" represents the scientific name of a snake.

---

**Question 6:**
**Kingdom**
The Kingdom taxonomic group includes the largest number of organisms compared to Phylum, Order, and Family.

---

**Question 7:**
**True**
Cyanobacteria were indeed extremely important to the evolution of life on Earth due to their ability to produce oxygen through photosynthesis.

---

**Question 8:**
**Reptiles**
Based on evolutionary relationships, reptiles are the group most closely related to birds.

---

**Question 9:**
**Extreme halophiles**
Extreme halophiles are archaea that thrive in environments with high salt concentrations.

---

**Question 10:**
**The materials that make up the cell walls of these organisms are very different from each other**
This is a major difference between bacteria and archaea; their cell wall compositions differ significantly.
