What is the difference between Bacteria and Archaea?
lol no
1. Determine the difference between archaea and bacteria. ARCHAEA LIVE IN EXTREME ENVIRONMENTS, WHILE BACTERIA CAN BE FOU D I. MOST PLACES ON EARTH.
2. Determine the difference between prokaryotes and eukaryotes. EUKARYOTIC CELLS HAVE A NUCLEUS, WHILE PROKARYOTES HAVE DNA THAT FLOATS AROUND INSIDE THE CELL.
3. Determine why multicellular organisms need multiple cells in Order to survive. THE CELLS OF MULTICELLULAR ORGANISMS PERFORM DIFFERENT FUNCTIONS AND RELY ON EACH OTHER TO SURVIVE.
4. What is an instinctive behavior? AN INHERITED BEHAVIOR
5. Why do sea turtles rely on instincts more than mammals do? SEA TURTLES MUST SURVIVE ON THEIR OWN, WHILE MAMMALS SPEND TIME WITH THWIR PARENTS AND LEARN HOW TO SURVIVE AS THEY GROW.
6. Which animal behavior described below is an example of a learned behavior? PRAIRE DOGS IN THE WILDERNESS HIDE WHEN A HUMAN APPROACHES, BUT PRARIE DOGS THAT LIVE NEAR CAMPGROUNDS ARE USED TO HUMANS AND DO NOT HIDE WHEN HUMANS APPROACH.
7. A species of pepper plants always grow large bell peppers in all environments. A plant that receives plenty of sunlight will produce more peppers than a plant that receives little sunlight. Which trait is inherited? Which is acquired? THE SIZE OF THE PEPPERS IS INHERITED. THE NUMBER OF PEPPERS PRODUCED IS ACQUIRED.
8. Can some inherited traits be changed by an organisms environment? YES, FOR EXAMPLE, AN ORGANISM’S SIZE INHERITED BUT CAN BE CHANGES BY DIET.
9. Dear are mammals, which means all deer are covered in fur. Deer live in many different environments, and all deer have for all your round. In the winter, dear grow thicker fur coats to help keep them warm. Which of these traits is inherited? Which is acquired? A FUR COAT IS AN INHERITED TRAIT. A THICK WINTER COAT IS AN ACQUIRED TRAIT.
10. Is it possible for two tall pea plants to produce a short pea plant variety? Explain. Yes, IT IS POSSIBLE FOR PLANTS TO PRODUCE OFFSPRING WITH TRAIT DIFFERENT FROM THEIR OWN.
11. True breeding parents CAN ONLY PASS ONE trait variant(s) to their offspring.
The difference between Bacteria and Archaea lies in their evolutionary history, cellular structure, and their ability to thrive in different environments.
To understand this difference, we need to consider their taxonomy. Bacteria and Archaea are the two domains of prokaryotes, which are organisms that lack a nucleus and other membrane-bound organelles.
1. Evolutionary History:
- Bacteria: Bacteria have a more diverse range of species and have been present on Earth for more than 3.5 billion years. They are considered more ancient and have a wider representation among different habitats.
- Archaea: Archaea were discovered relatively recently, in the late 1970s. They are also ancient organisms, but their distinct evolutionary lineage separates them from bacteria and eukaryotes.
2. Cellular Structure:
- Bacteria: Bacterial cells possess peptidoglycan in their cell walls, which provides structural support. They can have various shapes such as spheres (cocci), rods (bacilli), or spirals (spirilla).
- Archaea: Archaeal cells lack peptidoglycan in their cell walls and have unique membrane lipids. Some archaea have a single cell membrane, while others have a double membrane. They can have similar shapes to bacteria but often have more extreme shapes due to their ability to survive in extreme environments.
3. Environmental Adaptations:
- Bacteria: Bacteria exist in diverse environments and can be found in soil, water, and human bodies. They have a broader range of adaptations and can live in both extreme and moderate conditions.
- Archaea: Archaea are known for their ability to thrive in extreme environments, such as hot springs, deep-sea hydrothermal vents, and highly acidic or alkaline environments. They have unique adaptations to survive in these harsh conditions.
To determine the difference between a bacterial and archaeal organism, scientists typically examine their genetic material, specifically the sequences of certain genes or genomic regions. This process is often done through DNA sequencing techniques.
In summary, while both Bacteria and Archaea are prokaryotes, they differ in terms of evolutionary history, cellular structure, and environmental adaptations.
