Answer:
Answer : Scientific theories are rigorously supported by numerous studies, and are hypotheses that, even up till date, have never been disproved.
Explanation:
Scientific theory can be explained as a theory that was highly supported by facts. This means that , it is continuously or repeatedly confirmed by observation and experiment by scientists.
Evolution can be described as changes that occur in the heritable characters over a period of time. This usually occurs through natural selection.
In this case, evolution is known to be a scientific theory, because it involved careful observations and confirming experiments by scientists.
Answer:
a)BB*Bb
b)0:2:2(short: intermediate:long)
c)0
Explanation:
A naturalist visiting an island in the middle of a large lake observes a species of small bird with three distinct types of beaks. Those with short, crushing beaks (BB) consume hard shelled nuts, those with long, delicate beaks (bb) pick the seeds from pine cones, and those with intermediate beaks (Bb), consume both types of seeds though they are not as good at either. Assume that this difference in beak morphology is the result of incomplete dominance in a single locus gene. Which of the mated pairs below will have the best adapted offspring in a year in which most of the food available is in the form of hard shelled nuts? What would be the phenotypic ratio of the F1 generation resulting from a cross of Bb x bb(Short:Intermediate:Long)? How many offspring of an intermediate x short beak cross will have long beaks (assume 4)?
A) since the feed is put into consideration, then the offspring that is best adapted to feed on hard shelled but is to be considered. Cross-linking a gene BB with Bb is the best. If BB is said to be dominant then the offspring are produced will be short beak and intermediate beak in the ratio of 2:2 where both are suitable for feeding on hard shelled but.
B) The phenotypic ratio of the F1 generation (first generation or offspring) between Bb and bb is that there won't be a pure short beak(BB). Therefore 0:2:2 for short: intermediate: long.
C) for the intermediate and short beak crosslinking there won't be a long beak in the first generation when we limit the number offspring to four.
If he inherited a mutation that made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children is the circumstance that might his concern for his children be justified.
<h3>What do you mean by Mutation?</h3>
A Mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism.
Gametes of germline cells play an important role in the inheritance of mutation from parents to their offspring, which means that if a mutation has occurred in an egg or sperm cell, it will be more chances that the offspring carry mutated DNA.
Therefore, it is well-described above.

Protozoa are single-celled eukaryotic organisms. Many aquatic animals feed on protozoa. Protozoa help control the population of bacteria as well as other protozoans by feeding on them. Controlling the population of other organisms is important in maintaining ecological balance and diversity.
