Answer:
The correct answer is- have diverse cell wall composition
Explanation:
Bacteria and archaea are both prokaryotes because they both lack membrane-bound nucleus and other membrane-bound organelle. There are differences between bacteria and archaea which allow their differentiation into two different domains.
One of the main difference is the difference in their cell wall. The cell wall of bacteria is made up of peptidoglycan and the cell wall of archaea is made up of pseudo-peptidoglycan.
In peptidoglycan N-acetylglucosamine and N-acetylglucosamine are the two sugars but in archaea N-acetyltalosaminuronic acid (NAT) replaces NAM.

Positive feedback in a system is a benefit for the entire system
Answer: Option B
<u>Explanation:</u>
The positive mechanism is a stimuli that the body exhibits when in time of need which actually benefits the entire system. When required the positive feedback runs to rescue and neutralize the effect caused by the negative impact which paves a way to maintain equilibrium throughout the body.
Many examples can be cited for this like blood clotting, during labor and even in ripening of fruits. Positive and negative feedback work hand in hand to maintain homeostasis in place. Positive feedback is required to enhance the system while the negative feedback is to inhibit the activity.

Answer:</h2>
Following are the examples of the given associations:
- Mutualism- Oxpecker and rhinoceros.
- Commensalism- Birds and tree.
- Parasitism- Sashimi and round worm.
<h2>
Explanation:</h2>
- <u>Mutualism</u>- It is a the interaction of two organisms of two different species in which each of them gets benefited from each other. For example- Oxpecker eats the ticks, pests and other parasites present on the body of Rhinoceros and hence both of them get benefited as the oxpecker gets food and in return rhinoceros gets pest control.
- <u>Commensalism</u>- it is a association in which two organisms get interacted in which one get benefited and the other is neither benefited nor harmed. For example birds living on trees generally do not harm tree in any case but in return gets food and shelter from the tree.
- <u>Parasitism</u> in aquatic environment- it is defined as the interaction of two organisms in which a organism lives in or on other organism of another species (its host) and benefits by deriving nutrients from the host at the host's expense. For example round worm or tapeworm obtain food and even complete their life cycle inside fishes like Sashimi and harms them.
Result: The above are the examples of the given associations.
