Answer:
Brain consists of three major parts- cerebrum, cerebellum and the brain-stem.
Explanation:
Functions-
A) Cerebellum- helps body move more slow.
B) Cerebrum- Largest part of the brain consists of right and left half.
C) Hypothalamus- Regulates eating and drinking and body temperature.
D) Medulla- Controls basic life functions like heart rate.
E) Meninges- membranes that surround and protect the brain and spinal cord.
F) Midbrain- Plays a role in the maintenance of consciousness.
G) Pons-Controls movement of the eye and helps in auditory and visual processing
H) Thalamus-Passes signals from the spinal cord to the brain and controls breathing
I) Frontal lobe- Reasoning of judgement.
J) Partietal lobe- sense of touch of vibration.
K) Temporal lobe- Auditory processing and word meaning.
L) Occipital lobe- vision.
What is risbi? First of all
Answer:
The tasting allele is dominant.
Explanation:
- The law of dominance states that the dominant allele will always express itself in homozygous or heterozygous conditions.
- While, the recessive allele Can express itself only in Homozygous recessive condition.
- The phenotypic ratio in case of monohybrid cross is 3:1 where i.e , about 3 out of every four offspring tends to express the dominant trait.
- According to the given statistics,80% of the population can taste PTC and 20 % cannot.
- Thus The tasting allele is a dominant allele.
10^7 would be 69000000. You do this by moving the decimal by the number of powers on the 10.
Answer:
The correct answer will be option-The red and white flower alleles are co dominant.
Explanation:
The Mendel suggested that for any trait, the organism contains its alleles which could be dominant and recessive. But there are cases in which multiple alleles exist for the same trait which are neither dominant nor recessive.
Two cases arise due to this in which both the dominant alleles co-exist and show their phenotype effect called "co-dominance" and when both alleles form a new phenotype called 'incomplete dominance".
In the given case, the self-pollination produces red, white and patched flowers as a result of co-dominance because both the alleles show the equal effect on the flower petals (mixed phenotype) and form a flower with red patches or spots on the flower.
Thus, the selected option is the correct answer.
