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.
B.
Plants use light energy to produce food molecules during photosynthesis and obtain cellular energy from the bonds of these food molecules during cellular respiration.
The chlorophyll pigment in plants harnesses light energy to ‘manufacture’ glucose/carbohydrates which are later used by the plant for cellular respiration to power cell activities.
Explanation:
The energy from sunlight is used by the chlorophyll pigments to make ATPs through a process called photophosphorylation. In addition, the light energy is used to split water molecules into H⁺ and O²⁻. The H⁺ is then captured by NADP+ which is reduced to NADPH, while O²⁻ is evolved as oxygen. This occurs in the light stage of photosynthesis.
The NADPH is used to reduce carbon dioxide into glucose in the dark stage (Calvin cycle) of photosynthesis. Remember since this is an anabolic process ATPs (the one created through photophosphorylation) are used to power this cycle.
Excess glucose can be converted to starch and stored. Otherwise, the energy captured in the chemical bonds of the glucose are again utilized to make ATPs in cellular respiration.

It is due to the electron transport chain that is located in the mitochondria
The complete question is:
An individual with genotype AA is crossed to an individual with genotype aa at the same genetic locus. The allele A is dominant to the allele a.
If the offspring are interbred through two generations, what is the predicted ratio of phenotypes in the F2 generation?
9:16 (dominant:recessive)
9:7 (dominant:recessive)
3:16 (dominant:recessive)
1:3 (dominant:recessive)
Answer:
3:1 dominant:recessive phenotype ratios
Explanation:
The recessive phenotype disappears in the F1 generation, but it reappears in the F2 at a ratio of 3:1, being therefore dominant:recessive
