Answer:
Explanation:
A scientific researcher performs scientific methods to answer any natural process. The researcher will follow the protocol of a scientific method which includes: observe the natural phenomenon, ask related questions, suggest a hypothesis, perform the experiment and suggest answers.
In the given question if the researcher has to study about the flu virus, the possible questions he would ask will be:
1. The life cycle of the flu virus.
2. Effect of the virus on the life of an organism.
3. The mechanism used by the virus to replicate and to infect any organism.
4. Molecular mechanism of a virus.
Answer:
Parasitism
Explanation:
Parasitism is a form of relationship in which one of the organism is being harmed while the other benefits. The organism being harmed is usually called the HOST while the organism that benefits is called PARASITE. Parasites often inflict certain health-related conditions on their hosts.
According to this question describing the mode of feeding of ticks, they are said to eat by taking blood from other organisms such as wallabies, lizards, echidnas and occasionally humans, which are all HOSTS.
In human hosts, this relationship with ticks can lead to symptoms such as itching, head aches and in extreme cases flu like symptoms, facial paralysis, and meat allergy etc. From the description above, it is clear that TICK has a PARASITIC RELATIONSHIP with its host as it brings only harm to them and benefits itself.
Answer:
Koppean climate
Explanation:
It is a non-arid climatic condition in which the twelve months have mean temperatures which are warm. The temperature remains constant throughout the year. The sunlight remains intense in this zone.
Answer:
F2 progeny: 1/4 YY: 1/2 Yy : 1/4 yy
Gamete frequency (for both male and female gametes)= 1/2 Y : 1/2 y
Explanation:
Given that the genotype of the both parents is "Yy", each of the parent would produce two types of gametes. The 1/2 of both the male and female gametes would have "Y" allele while the rest 1/2 would have "y" allele.
This is due to the fact that each gamete carries only one allele for any gene due to segregation of homologous chromosomes to the opposite poles during anaphase I of the meiotic division that forms gametes.
The random fusion of these male and female gametes would given the F2 progeny with genotype frequency= 1/4 YY : 1/2 Yy : 1/4 yy.
Answer:
Over thousands of generations, many mutations will be introduced into a population and some of these will increase to a detectable frequency as a result of selection or genetic drift. Both of these processes may take a long time to make a measurable increase in allele diversity. hope this helps :D
