Answer:
The small number behind each element symbol designates the number of atoms of each element in a chemical formula. If there is no number, it is assumed there is only one of those elements. A large number in front of a compound designates how many units there are of that compound.

Complete question:
If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.
Answer:
CC - homozygous dominant
cc - homozygous recessive
Cc - carriers
cc will have the phenotype
Explanation:
Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.
Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease
In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype
Answer: Equation for photosynthesis is carbon dioxide + water + sunlight→ Glucose + oxygen
In light dependent reactions, energy in form of solar energy is absorbed and converted to chemical energy.
Explanation: During photosynthesis, sunlight is absorbed by the light absorbing pigment called chlorophyll. The absorbed solar energy is converted into chemical energy using carbon dioxide and water as the starting materials with the release of oxygen. The equation is 6 CO2 + 6 H2O + solar energy --> C6H12O6 + 6O2.
Photosynthetic reactions are made up of two parts: the light dependent reactions and the carbon fixation reactions. In the light dependent reactions, chlorophyll and other photosynthetic pigments absorb light energy from the sun and conserve it as ATP and NADPH with a simultaneous release of oxygen. The carbon fixation reactions are driven by the products of the light dependent reactions.
