This is a point mutation.
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.
Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant's leaves. Oxygen moves out of the plant leaf through these same openings.
Answer:
The two basic function of meiosis is listed below.
1. Genetic recombination:
In meiosis crossing over occurs that results into genetic recombination.
2. Ensure constant chromosome number:
The number of chromosomes reduce to half in germ cells that reunite in sexual reproduction and ensure the survival of species by keeping constant chromosome numbers. Have a good day.
Answer:
D
Explanation:
Prokaryotic cells have no nucleus, eukaryotic cells do. A squirrel is eukaryotic, therefore it’s genetic material will be stored in the nucleus.
