Dominant trait = T (tall)
recessive trait = t (short)

heterozygous, meaning different, tall pea plant = Tt
short, short being recessive, pea plant = tt

phenotype means physical looks, which is either tall or short

T t

t | Tt tt
t | Tt tt

two Tt & two tt meaning there are 2 tall and two short. therefore,
1:1

If a disease affected a paramecium's contractile vacuoles, stopping the normal functioning of the vacuoles, what would happen to
BabaBlast [244]

The paramecium would not be able to get rid of excess water so the cell would burst.

FUNCTION OF THE CONTRACTILE VACUOLE:

  • The contractile vacuole is an organelle present in protist organisms like paramecium, amoeba etc.

  • The contractile vacuole functions to regulate water balance in the cells of organisms that they are found. Contractile vacuole performs this function by storing excess water and expelling the out of the cell.

  • Hence, if a disease affected a paramecium's contractile vacuoles, stopping the normal functioning of the vacuoles, the paramecium would not be able to get rid of excess water so the cell would burst.

A bacterial infection of the periodontium that causes rapid attatchment loss and poor response to periodontal therapy has a grade of Aggressive periodontal disease

<h3>Periodontium </h3>

The cementum, gingiva, periodontal ligament (PDL), and alveolar bone make up the complex structure known as the periodontium. The periodontium's main purposes are to protect the underlying structures of the tooth from the oral microflora and to enable the tooth to connect to the bone.

An orthokeratinized or parakeratinized stratified squamous epithelium makes up the gingival epithelium. The gingiva, which has connective tissue and epithelial components, covers the supracrestal root surface and the alveolar bone. As it lines the gingival sulcus close to the tooth surface (enamel or cementum) and subsequently joins to it with hemidesmosomes, the gingival (oral) epithelium develops into the sulcular epithelium and junctional epithelium.
