Answer:
All the options are true except option D.
Explanation:
Archaea are a group of prokaryotic organisms i.e. they lack a membrane bound nucleus. They are one of the the three domains of life (the other two being bacteria and eukarya). Archeans possess a cell wall like bacteria but it is not composed of peptidoglycan, like bacteria cell wall.
Archeans are generally known to be found in very severe environmental conditions, hence, they are referred to as extremophiles e.g Some are thermoacidophiles i.e. thrive in very hot and acidic environment while others are extreme halophiles i.e. thrive in salty regions. Archeans known as methanogens produce methane gas as a product of metabolism from carbon dioxide and hydrogen.
However, the domain archeae was only found to be in existence recently after the domain bacteria, hence, they are not considered to evolve before the domain bacteria.
a feedback mechanism that maintains homeostasis
Explanation:
Anhidorosis mostly directly interferes with a feedback mechanism that interferes directly with a feedback mechanism that maintains homeostasis.
Since anhidorosis is the inability to properly or normally sweat, it affects the process of homeostasis.
Homeostasis is an important characteristics of life.
It is the ability of organisms to maintain and sustain a balance environment within and outside of them.
Sweating is one such process by which the body carries out homeostasis. On a hot day, the body produces sweat which evaporates and release latent heat to cool the body. This inability affects the intricate balance between the environment and the body.

<span>4 is a good answer. The question ‘can planting cover crops reduce erosion’ can be easily answered by creating a scientific study. You could create an experimental group where cover crops are planted and a control group where they are not, and measure the erosion of each group. </span>
They increase the permeability of the lymph capillaries. Interstitial fluid enters the lymphatic vessels through the mini valves (which are overlaps of endothelial cells
from multiple lymph capillaries). The valves also prevent the backflow of the lymph from the vessels back to the tissues.
Some codons are sup pressed, so they do not appear to be producing any proteins. These amino acids may be part of such codons.
