Answer;
-They all provide water
Explanation;
In reaction A, the reactants are glucose and fructose , and the products are Sucrose and water. This is a condensation reaction, following the combination of two monosaccharides (glucose and fructose) forming a dissaccharide (sucrose) and water.
In reaction B, the reactants are two amino acids, that results to formation of a dipeptide and water; this is also a condensation reaction joining two amino acids monomers, to form a dipeptide and water.
-In reaction C, a monoglyceride combines with a fatty acid to form a diglyceride and water. This is also an example of a condensation reaction that results to formation of a diglyceride and water.
Therefore, the similarity of all the reactions is that they are all condensation reactions, with water as a common product.
Tiktaalik is a transitional fossil which shows how fish evolved into amphibians and reptiles. So the correct option is B.
What is Tiktaalik?
Tiktaalik is a direct ancestor of tetrapods or four-legged animals. It is an extinct fish-like animal and it lived on earth 380-385 million years ago (Devonian period).
The word Tiktaalik is derived from the <em>Inuktitut</em> language which loosely translates to large freshwater fish. This animal had characteristics of both fish and tetrapod and is therefore called the link between these two kinds of animals.
The characters resembling fish are gills and scales and the characters resembling tetrapods are rib bones, movable neck and lungs. There are characters that are a mix of both tetrapods and fish. These are bones and joints in limbs but fish-like fins instead of feet or hands.

Answer:
Recessive
Explanation:
A recessive disorder is expressed in a homozygous genotype only. Most of the recessive disorders are not expressed as the expression of the recessive allele is masked by a dominant allele in the heterozygous state. However, breeding between close relative (inbreeding) increases the homozygosity in the population and allows the expression of recessive alleles that were otherwise not expressed in the population.
According to the given information, the disease is rare and is mostly expressed in the progeny obtained by mating between closely related individuals (the first cousins). Therefore the disease is inherited in an autosomal recessive pattern.
Uncontrolled cell division is called cancer
