Hey there! :D
When we are talking about gametes, we can use a punnet square, or in this case, common knowledge. If two of the alleles for one phenotype are the same, we can infer there will only be two variations of the genotype. (because there are two dominant SS genes) We already know that "D" must be the answer. Firstly, there will be one allele for each gene, so there will always be an "S" and a "T" no "SS" or "tt" (when talking about gametes). That leaves us with B and D but there is no recessive "s" in the original genotype, so the answer must be "D". 
I hope this helps!

Answer: Different liquids will evaporate differently depending on the force of attraction between the molecules of the liquid. The weaker the force of attraction the higher the rate of evaporation and vice versa.
 In Sea water the water molecules are attracted to the salt ions and thus it requires more energy to evaporate.
 
 
        
             
        
        
        
Mitosis is a kind of cell division that produces 2 daughter cells that is genetically identical to both the other daughter and the parent cell.
By the word genetically identical, it means that they have the same number of chromosomes.
This process starts by a parent cell doubling their chromosomes, then, it divides, and therefore each daughter cells receive the original number of chromosomes.
Therefore, the answer to this question is 2 cells, 12 chromosomes each.
        
             
        
        
        
Answer:
Homology is a study of similar characters found in two species because of common ancestry.
Explanation:
1.Morphological homology: Species placed under same taxonomic category exhibit similar anatomical structures.
2.Ontogenetic homology: Species belongs to same taxonomic category embryological similarities
3.Molecular homology: Species show molecular similarities such as DNA,RNA and protein
An example of homology is seen in the skeletal strycture of vertebrates. That is arm of a human,leg of a cat,fin of a whale and wing of a bat.
