Perigee is the answer it is closest to the Earth
Answer:
nucleus, cytoplasm, mitochondria
Explanation:
The correct answer is Broca's area. This is because Broca's area is the part in the cerebral cortex, specifically in the temporal lobe (not in the frontal lobe), and is responsible for producing language. Damage in the Broca's area will render the patient unable to speak words correctly and this is called expressive aphasia. The Wenicke's area on the other hand is also located in the temporal lobe and is responsible for interpreting language. Damage in the Wernicke's area will make all words to the patient non-understandable even when he can hear the words correctly and this is called receptive aphasia. Occam's area and Morton's area are not parts of the brain and does not exist.
Nice to know: There is a nerve tract that connects Broca's area to Wernicke's area called the arcuate fasciculus. Damage to the arcuate fasciculus will render the patient unable to repeat words.
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.
