Infect with what a sickness?
A parasite moving between individuals other than parents and their offspring uses
horizontal transmission.
Horizontal transmission is the transmission of infections between (parasites) that are not in a parent-child relationship (vertical transmission). Horizontal transmission may include the carriers or <span>vectors which are other species. Transmission, in that case, occurs via the bite of the vector (an infected organism), like in malaria.</span>
Answer:
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents
Ans.
Animals are multicellular, eukaryotic organisms that belong to domain eukarya. They have cells with membrane-bound cell organelles, such as mitochondria, endoplasmic reticulum, nucleus, Golgi body, and lysosomes. In these organisms, genetic material is present inside the nucleus (known as true nucleus), which is surrounded by double-membrane system.
Thus, the correct options are:
-They contain a nucleus.
-They are eukaryotic.
-They contain membrane-bound organelles.
