Answer:
A. motor neurons; peripheral nervous system
Explanation:
Motor neurons carry signals from the peripheral nervous system to the muscles. This causes the muscles to either relax or contract. Note that the peripheral nervous system consists of neurons and parts of neurons outside of the central nervous system which consists of the brain and spinal cord. When signals are transmitted between the motor neurons and peripheral nervous system, this causes a response to stimulus in the muscles which would either, relax or contract.
Ezywhen salinity in soil increases the soil becomes hypertonic when compared to cell sap.the movement of particles from a lower concentrated solution to a higher concentrated solution is callede osmosis. in general conditions cell sap is at higher conc. than surrounding media. this allows water and minerals to enter the plant. but when soil is at higher conc. i.e., when its salinity increases the process becomes reversed can you imagine its consequenses?
The area of the frontal lobe that is devoted to the production of fluent speech is the Broca's area. It contains neurons that is involved in speech production and language comprehension. It is classified into two parts namely the pars triangularis and the pars opercularis.
Answer:
True
Explanation:
The dominant allele increases in frequency as it masks recessive alleles.That is why a dominant trait/allele will become something is more commonly passed down to offspring
The Prader-Willi syndrome (PWS) is due to the lack of expression of paternal genes of the 15q11-q13 region. It usually occurs sporadically, although some family cases have been described (<1%). Approximately 70% of cases are produced by deletions of paternal origin in the 15q11-q13 region. 28% of cases are due to maternal uniparental disomy and less than 2% are caused by imprinting alterations. A geneticist studying prader-willi syndrome should focus on chromosome 15, its structure or changes in the number, these anomalies are also related to other syndromes such as: Bloom Syndrome, Breast cancer, Isovaleric acidity among others.
