Answer:
Since both Anthony and Sara are healthy carriers of the gene that causes cystic fibrosis, the chance of having a child with this disease are 1:4 (option D).
Explanation:
The inheritance pattern of cystic fibrosis is autosomal recessive, and considering that both parents carry the abnormal CFTR gene, it can be said that the parental genotypes are:
<em>Anthony N/Qf
</em>
<em>Sara N/Qf
</em>
Where N is the normal gene and Qf is the abnormal gene.
Since this is an autosomal recessive disorder, only the homozygosity of the defective allele will cause the disease to manifest
:
N/Qf X N/Qf
<em>Alleles N Qf
</em>
<em>N N/N N/Qf
</em>
<em>Qf N/Qf Qf/Qf
</em>
- The chances of having a healthy child are 25%.
- The chances of having a carrier child are 50%.
- The chances of having a child with cystic fibrosis are 25%.
Therefore, the chance of Anthony and Sara having a child with cystic fibrosis is 1:4.

Explanation:
When using chromatography, the 2 solutes in the solvent paper should have different Rf values from the base line to identify them as different compounds.
If they were to have the same speed in the solvent, they would appear as 1 dot instead of 2 separate dots, which is a false reading.

Characteristics of Fungi
Fungi are eukaryotic, non-vascular, non-motile and heterotrophic organisms.
They may be unicellular or filamentous.
They reproduce by means of spores.
Fungi exhibit the phenomenon of alternation of generation.
Fungi lack chlorophyll and hence cannot perform photosynthesis.
Answer:
The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion.
