Answer:
b. It allows gas exchange while preventing water loss
Explanation:
Amniotic eggs are the feature of land animals such as reptiles, birds, mammals, etc. The amniotic eggs have four extra-embryonic membranes. This semipermeable protective shell allows the exchange of respiratory gases but does not support the transport of water out of the egg.
The ability to maintain the water inside the egg while permitting gaseous exchange is the specific feature of amniotic eggs and allowed diversification of land animals in the land habitats.
Mitochondria and chloroplasts reproduce independently from the cell. b. Mitochondria and chloroplasts contain their own ribosomes. c. Mitochondria and chloroplasts have DNA that resembles bacterial DNA. d. Mitochondria and chloroplasts are much larger than prokyoktoes
Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.
Rhizoids can be called roots of bryophytes.
Rhizoids<span> are simple hair-like protuberances that extend from the lower </span>epidermal cells<span> of </span><span>bryophytes.
</span>Rhizoids are long, thin cells that anchor bryophytes in the ground <span>and absorb water and minerals. </span>
Cold air is drier because the water molecules are more likely to condense to a liquid.
This was the answer on my course, hope it helps!
