We'll make the alleles: Cc.
C is a healthy parent, and c is the cystic fibrosis (recessive).
If you make a punnett square and the parents are both Cc (healthy), then you would get CC, Cc, Cc, and cc. That cc is a 25% chance that the offspring will have that, which means there is a 25% chance the child will have cystic fibrosis.
Two healthy parents can have a child with cystic fibrosis if both the parents have the dominant allele and recessive allele, if both the parents have heterozygous alleles.
The types of evidence for evolution include
i) Changes in allele frequency over subsequent generations.
ii) When the population in question is examined it does not follow Hardy-Weiberg equilibrium.
iii) Signs of gene flow between populations.
iv) Presence of Sewall-Wright effects or genetic drift in the population.

The temperature of the water after adding the chemical.
Answer:
In C4 photosynthesis, where a four-carbon compound is produced, unique leaf anatomy allows carbon dioxide to concentrate in 'bundle sheath' cells around Rubisco. This structure delivers carbon dioxide straight to Rubisco, effectively removing its contact with oxygen and the need for photorespiration
