Answer:
P53, EGFR and KRAS genes
Explanation:
Mutations on somatic cells will disturbs the cell cycle and induce cell proliferation which lately results in tumour formation. The mutated P53, EGFR and KRAS genes causes lung cancer. P53 has direct contact with DNA acts a suppressor of tumour and guards the cell divisions. When these genes are mutated they induce expression of different genes (especially P53) leading to lung cancer.
Answer:
At about 38 weeks after conception, the fetal brain signals the release of hormones, specifically <u>oxytocin,</u> which prepares the fetus for delivery and begins labor.
Explanation:
Oxytocin is a hormone released by posterior pituitary gland because it is responsible for the uterine contractions during labour.
Fetal hypothalamus secretes corticotropin releasing hormone near term which stimulates fetal Anterior pituitary gland to secrete adrenocorticotropin hormone (ACTH) which stimulates adrenal cortex to produce cortisol which stimulates the secretion of estrogen from placenta, inhibition of P synthesis causing increased uterine contractions by cauisn increased oxytocin released from posterior pituitary gland.
Relay Neurons are found between sensory input Anne motor output/response. Relay Neurons are found in the brain and spindle cord. They allow sensory and motor neurons to communicate. Motor Neurons are found in the central nerve system (CNS)
And control muscle movements
Explanation: The stretch-shortening cycle (SSC) refers to the muscle action when active muscle lengthening is immediately followed by active muscle shortening. ...
