Babesiosis is a malaria-like parasitic disease caused by infection with Babesia bigemina, a genus of protozoa piroplasms. 
Syphilis -  Treponema pallidum (bacterium)
Influenza - Influenza virus
Blastomycosis - Blastomyces dermatitidis (fungus) 

Parthenocarpy is a process of developing fruits without involving fertilisation/seed formation. Therefore, the seedless varieties of economically important fruits like orange, banana, watermelon, lemon, etc. are produced using this technique. This technique involves inducing fruit formation by the application of plant growth hormones such as auxins. 

Grafted kidney may be rejected in a patient due to the cell-mediated immune response that is mediated by T-lymphocytes. The body is able to differentiate 'self' and 'non-self'. Therefore, tissue matching, blood group matching are essential before undertaking any graft/transplant and even after this the patient has to take immuno-suppressants all his/her life. 

Pleiotropic gene is a gene that controls multiple traits is an individual. It is also called polyphenic gene, e.g., phenylketonuria causing multiple adverse effects due to the mutation in a single gene coding for enzyme phenylalanine hydroxylase.

Eutrophication is a process where water bodies receive excess nutrients that stimulate excessive plant growth. This can lead to overcrowding and competition for sunlight, space and oxygen.
This condition creates the lacking of essential nutrients for fishes due to which they die. 

Pollen grain or male gametophyte in angiosperms contain one generative cell. The generative cell. The generative cell further divides mitotically to form two male gametes(sperms). So, a mature male gametophyte in angiosperms contains two sperms and one vegetative cell. 

Acid rain is caused by increase in the atmospheric concentration of SO₂ and NO₂. These mix with water vapour to form sulphuric acid (H₂SO₄) and nitric acid (HNO₃) respectively which falls on earth in the form of acid rain. 

Satellite DNA forms that minor peak after centrifugation of DNA. These are repetitive DNA sequences that do not code for any protein. They show high degree of polymorphism and heritable from parents to children, thus form the basis of DNA fingerprinting. 

Competition is a negative interaction that occurs among organisms whenever two or more organisms require the same limited resource.
