That would be a hypothesis
Hope this helps you :)))
Answer:
After you have established a research question, which of the following should you do first?
put your research question into a null and alternative hypothesis
Explanation:
It expedient that after research question has been established, one needs to make a null hypothesis and alternate it, this gives a clue of what the researcher intends to find or problem to be solved.
Answer:
1) The alleles for homozygous brown hair will be BB.
2) The alleles for heterozygous brown hair will be Bb
3) Let's make a punnet square to check for the outcomes:
B b
B BB Bb
B BB Bb
4) The results from the punnet square depict that the phenotype of all the children produced will be brown hair.
5) The punnet square depicts that there will be a 50% probability of the child to carry the heterozygous genome (Bb) and there is also 50% probability for the child to carry homozygous dominant genome (BB).
The correct answer is option D The population of foxes would probably decrease.
A food chain can be defined as a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. Each level of the food chain is called the trophic level. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.
In the terrestrial food chain given above, grass → rabbit → fox, the decrease in the any population will effect the other organism at a different trophic level of the food chain. A sudden decrease in the population of rabbits will decrease the population of the foxes at the next trophic level as it is a secondary consumer feeding on the primary consumer which is the rabbit. So, a sudden decrease in the rabbit population will starve the foxes and thus decrease their number in the island.
