Answer:
The correct answer is "The eggs must have internal membranes".
Explanation:
Amniotes are animals that have adapted to reproduce putting eggs on land (reptiles, birds or mammals). The eggs of amniotes have internal membranes that let gases but not water pass through. This characteristics allows the embryo to breath inside the egg, and allow the egg to not dry out on land. Therefore, the eggs of the new species of animal must have internal membranes in order to allow its reproduction on land.
The fulcrum is the point in any mechanical device where the moment due to weights is zero.
(Weight 1 x distance 1) - (weight 2 x distance 2) = 0
(1.7 Kg x 1.5 m ) - (weight 2 x 1.2 m) = 0
weight 2 = (1.7 Kg x 1.5 m ) / 1.2 m
= 2.1 Kg

During bread making, metabolism of simple sugars by yeast produces carbon dioxide which makes the bread rise.
The essential ingredients of bread dough are flour, water and yeast. As soon as these ingredients are stirred together, enzymes in the yeast and the flour cause large starch molecules to break down into simple sugars.
The yeast metabolizes these simple sugars and exudes a liquid that releases carbon dioxide and ethyl alcohol into existing air bubbles in the dough. If the dough has a strong and elastic gluten network, the carbon dioxide is held within the bubble and begins to inflate it, just like someone blowing up bubble gum.
As more and more tiny air cells fill with carbon dioxide, the dough rises, and so we see bread rising.
