Answer:
1. Tt
2. Tall
3. BB
Explanation:
1. The genotype of the organism is used to define its genetic constitution. To write down the genotype of an individual an alphabetic symbol is often assigned to it and then depending on whether the person is homozygous or heterozygous, his genotype is written down.
For e.g, If T is the allele for tallness and t for shortness and the person inherits both these alleles then his genotype would be Tt.
2. A person's phenotype refers to the external characters that are visible due to the particular genotype the person has. For eg., if a person inherits an allele for tallness then he has a phenotype of being tall.
3. A person is said to have a homozygous genotype if he carries the same allele for a given trait and is said to be heterozygous if he carries different alleles.
The organism that has no specialized cell is Paramecium.
Paramecium are members of the phylum Ciliophora. They feed on organisms like bacteria, algae, and yeasts . These organisms uses cilia to sweep the food along with some water into the cell after it falls into the oral groove. The food then goes through the cell mouth into the gullet.

Answer & Explanation: Cholera as a disease is any of the several acute infectious diseases of humans and domestic animals caused by certain strains of the Vibrio cholerae bacterium.
a) It is unlikely to spread directly from one person to another. So the risk of becoming ill through casual contact is quite low. However, for those with weakened immunity, they could possible contract the disease on contact leading to infection.
b) Signs of infection is usually marked by severe gastrointestinal symptoms such as diarrhea, abdominal cramps, nausea, vomiting and dehydration
c) Some of the different ways the disease could be spread include ingestion of contaminated water. Bacteria present in the faeces of an infected person are usually the main source of contamination.
