Answer:
Secondary succession
Explanation:
When a previously occupied area is re-colonized after a natural disaster or human activities that wiped out the previous community, then the type of succession is called a secondary succession. A practical example is abandoned farmland that a farmer left for a period of time and later revisited for farming afterwards.
Because the pioneer organism( sun-loving plants ) were already on ground it will be fast for them to populate the area,grasses will sprout up too. insects, dentritivores, reptiles will move into the habitats.
After 5years;The habitat is populated by shrubs, which owns the forest floors. small pine, oak may soon join.a stable climax community.
Assuming the community is not interfere with bigger dominant trees , e,g the oak developed and other tree developed to bigger tree , followed by more insects, birds, rodents, herbivores and some carnivores, This entire sequence of event may take 50 years, to reach this climax community.
Answer:
C) all chinchilla
Explanation:
As we know that dominance of alleles for the coat color in rabbits goes like this:
C+ > Cch > Ch > C.
- The allele for full colour or agouti is designated as C+.
- Allele for mutant coat color silvery- gray coat-chinchilla is Cch.
- Allele for “Himalayan” coat is called ‘Ch
- Albino rabbits have whole white coat and allele for this is c
If we cross homozygous chinchilla with homozygous chinchilla the cross will look like this:
P1: chinchilla x chinchilla
P1: Cch Cch X Cch Cch
F1: Cch Cch : Cch Cch
Since all offspring have Cch Cchgenotype that is foe chinchilla phenotype it means that all the offspring will have chinchilla phenotype that makes option C correct.
