The part of the CNS that is responsible for these functions is the brain stem.
The brain stem is the part of the brain that control very basic functions of your organism and lets them work together as they should. The other parts that are mentioned all have much more specific and also different roles.
Answer:
Fairy penguins (Eudyptula minor), also known as little penguins, are tiny, slate-blue animals found along the coastlines of southern Australia and New Zealand. Not only are they more colorful than most aquatic birds, but they're also notably smaller, growing to be less than a foot tall and about 2.5 pounds.
D. skeletal muscle and cardiac muscle
Answer:
Option-D
Explanation:
In the given question the genotype of parental allele is- AbaB X AbaB. The alleles formed will be- AB, Ab,aB, ab in which the crossover allele will be AB and ab.
1. Unlinked genes
Now of these alleles are unlinked then the alleles will assort independently of each other therefore performing the punnett square we will get dihybrid ratio as 9:3:3:1 in which
1. A_B_ are 9
2. aaB_ are 3
3. A_bb are-3
4. aabb- 1
Since the crossover allele are AB and ab therefore A_B_ are 9 and aabb- 1 represent recombinant genotype.
2. Linked genes
When the genes will be linked then chances of crossing over will be reduced as a result of which only two type of allele will be formed which are- Ab and aB and the recombinant frequency will become less.
Crossing these allele will form Aabb
, AaBb
, AaBb and aaBB genotypes.
The recombinant ratio will decrease as A_B_ is 2 and aabb is not present.
Thus, option-4 which states that the unlinked ration is 9:3:3:1 and linked ratio is <9: >3: >3: <1 is correct.
Answer:
The length of daylight and nighttime would decrease.
Explanation:
If 24 hours was decreased to 20, it would shorten night and day time.
