Answer: 1) Recessive allele is unable to express its effect in the presence of dominant allele WHILE a dominant allele is able to express itself even in the presence of its recessive allele.
2) Recessive allele produces its phenotypic effect only in the presence of a similar allele. E.g; tt is dwarf. WHILE a dominant allele does not require another similar allele to produce its effect on the phenotype. E.g; Tt is tall.
3) Recessive allele forms a defective polypeptide or enzyme so that the expression consists of absence of the effect of dominant allele. E.g; white flower colour in Pea. WHILE a dominant allele can form a complete polypeptide or enzyme for expressing its effects. E.g; red colour of flower in Pea.
Explanation:
Answer: Sensory mechanisms are responsible for detecting the external stimuli present in the environment.
Explanation:
The sensory mechanisms help people to observe things around them through eyes, they can hear the sounds through their ears, they can feel the insect creeping on their skin by touch sensory mechanism, they can taste food which they cook through taste or gustatory receptors present on tongue and other parts of mouth cavity.
Answer:I guess c. Seems like that’s the right answer
Explanation:
It’s mass and speed. This is because the equation for Kinetic energy is KE=1/2mv^2
It will take 15 years for Della to be in the same risk of
non-smoking persons in risk of cardiovascular disease. As you quit smoking, the
lungs will start to purify itself, but it will take some time. On the other
hand, it cannot be assured that the lungs may be totally restored, more or less
it would just be clean over a period of time.
