The correct answer is A since i can't see what is under it
Some ncds, that includes Parkinson's disease usually begins with impaired motor control. Parkinson's disease is a neurodegenerative disorder, that then leads to progressive deterioration of the motor function because of the loss of dopamine in brain cells. The cause is unknown yet mostly because of geneti or environmental factor.
Answer:they make useful substances, including: wax, honey, laquer, and silk
Explanation:
Answer:
Variable expressivity, Incomplete penetrance, Phenocopy, Genetic heterogeneity
Explanation:
Phenocopy: When an environmentally caused phenotype mimics one that has a genetic basis. The variation in phenotype caused by environmental conditions exists in such a way that the organism's phenotype matches a phenotype which is determined by genetic factors.
Variable expressivity: When a characteristic is subject to a range in severity or degree of expression in the phenotype.
Genetic heterogeneity: When the same phenotype/disease can be caused by different genes.
Incomplete penetrance: When individuals have a genotype that specifies a particular phenotype but that phenotype does not develop.
