Explanation:
<h2>In order to do photosynthesis, a plant needs sunlight, carbon dioxide (CO2) and water. Once the sugar is made through photosynthesis, it is then broken down by the mitochondria to make Page 2 energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.</h2>
Niacin is another name for nicotinic acid. It is an organic compound that is synthesized in the liver. The essential amino acid that is utilized to synthesize niacin is tryptophan.

The answer is D.
Answer: answer A
Explanation:
All of the cells definitions are correct and that’s how we learned which one was different
The probability of Sean to both sing and dance well is 50%.
<h3><u>Explanation:</u></h3>
The gene that is dominant is expressed in phenotype of the individual and the genes are actually obtained from the parents.
Here two characters are mentioned which are singing and dancing.
The dominant character i.e able to sing is marked by gene S and the corresponding recessive allele is marked by gene s.
Similarly, the ability to dance is marked by gene D and recessive allele is marked by gene d.
So, the mother is heterozygous and she can sing well, but can't dance. So her genotype is Ssdd.
The father can't sing and is homozygous, so his genotype is ssDD.
Gametes from the mother is Sd and sd. While the gamete from the father is sD.
So the probabilities of the progenies are SsDd and ssDd.
So the probability of Sean to both sing and dance well is 50%.
