Answer:
pigs
Explanation:
Influenza is an infectious disease caused by influenza viruses, which can be divided into four types A, B, C and D. In humans, influenza A and B viruses are known to cause epidemics, while A viruses are known to cause pandemics. Influenza viruses are also found in birds and mammals (e.g., dogs, cats, cattle pigs and horses). Cross-species virus transmission refers to the transmission process of infectious viruses between hosts from different species. Several viruses that may cause severe diseases in humans have originated from animal species, e.g., avian influenza A virus that can be transmitted to humans through an intermediate host (e.g., pigs). Other examples of cross-species virus transmission include the Ebola virus and Hantaviruses. It has been suggested that cross-species transmission is a common phenomenon in rapidly evolving viruses.
Symbiotic Relationships :
A long term relationship between two biotic factors, where at least one benefits
Mutualism= symbiotic relationship where both organisms benefit (+,+) o Example- rhino & woodpecker (rhino gets rid of parasites and bird gets food)
Parasitism = symbiotic relationship where one benefits and the other is harmed, but not typically to the point of death (+,-) o Example- tapeworm in an animal, tick or flea on a dog (parasite benefits at the expense of the host)
Commensalism = symbiotic relationship where one benefits and the other is neither helped nor harmed (+, 0) o Example- barnacles on a scallop (barnacles get a habitat/place to attach while the scallop is not hurt or helped by their presence).
Symbiotic Relationships:
In symbiosis, two or more species live together in a close, long term association. Symbiotic relationships can be beneficial to both organisms or may benefit one organism and leave the other harmed or unaffected. Parasitism is one type of symbiotic relationship that is detrimental to, or harms, the host organism. In this relationship, one organism feeds on and usually lives in another, typically larger, organism. Mutualism is a symbiotic relationship in which both participating species benefit. A well known instance of mutualism involves ants and aphids. The ants feed on fluid the aphids secrete, and in exchange, the ants protect the aphids from insect predators. A third from of symbiosis is commensalism, a symbiotic relationship in which one species benefits and the other is neither harmed nor helped. Among the best-known examples of commensalism are the feeding and protection relationships between certain small tropical fishes and sea anemones, marine animals that have stinging tentacles.

Answer:
The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".
Explanation:
The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.
In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.
Answer:
bb would be the phenotype white fur
Explanation:
B is dominant over b. It takes two recessive alleles to produce the phenotype of white fur.
D. Visible light . Is the correct answer I hope this helps:)
