To know what happens here, we need to see how alleles work.
You have three species: cremello, chestnut, and palomino all will be homozygotes with two alleles each.
One of these will be recessive (aa), one will be dominant (AA), and one will be a mixture (Aa).
You know the offsprin, so Cremello and Chestnut are the recessive and dominant ones. If you draw the Punnett square, you'll find out all breeding are pure.
Now, if you draw de Palomino Punnett square having one recessive allele and one dominant allele from each paren, you'll found 1/4 cremello (aa), 1/4 chestnut (AA) and 1/2 palomino (Aa).
protein is a macromolecule and protein is made up of amino acids.

Answer:
(C) The molecules essential to life today could have formed under early Earth conditions.
Explanation:
The results of Miller's experiments better support the hypothesis that molecules essential for life today could have formed under early Earth conditions. That's because Miller, in his hope, created an environment very similar to primitive earth. This environment consisted of water vapor, hydrogen gas, methane and ammonia, but this environment was able to synthesize organic molecules after receiving a discharge of electric sparks, which can be seen in the theory that explains the origin of life on earth.
The earth's atmosphere had a different composition from today. It is believed to be composed of methane, ammonia, hydrogen and water vapor. Strong lightning strikes and sun-radiated ultraviolet rays would have promoted a wide variety of chemical reactions in the atmosphere, leading to the emergence, among others, of simple organic molecules such as alcohols, amino acids and sugars.
Adenosine regulates synaptic activity through its actions on presynaptic autoreceptors. Adenosine A1 receptors are expressed at a presynaptic locus withinside the BLA and that activation those receptors substantially inhibits glutamate launch possibility onto BLA pyramidal neurons.
The adenosine A2A receptor is a G-protein-coupled receptor that may be a most important goal of caffeine and vital for regulating myocardial oxygen consumption, coronary blood flow, and CNS neurotransmitters, hence a receptor of hobby for brand new drug development.
The adenosine A2A receptor is particularly gift with inside the brain, heart, lungs, and spleen. The adenosine A2B receptor has its most important distribution with inside the big gut and bladder, and the adenosine A3 receptor is gift inside the lungs, liver, brain, testis, and heart.
