Answer: D
Explanation:
Could RNA have provided a template for DNA assembly, thereby enabling a more stable molecule that is replicated more accurately?
I think it isn't right to claim that an attribute developed so the species included can survive better, qualities advance since people with that characteristic survive better and duplicate more.
I hope the answer will help you.
The hormones which cause Jane’s problem are the thyroid hormones.
The condition is hypothyroidism
Explanation:
Condition: Hypothyroidism is an endocrine disorder which arises when the thyroid gland cannot produce the necessary amount of thyroid hormones like thyroxine (T4) and triiodothyronine (T3).
Both T3 and T4 are tyrosine-based hormones which regulate metabolism and any deficiency slows down the metabolic processes and can result in high cholesterol levels and atherosclerosis
Causes: An underactive thyroid gland and Autoimmune disorder
Diagnosis: Thyroid function tests by measuring serum thyroid stimulating hormone (TSH) and T4 levels
In hypothyroidism, the TSH secreted by the pituitary gland will be high because it is producing more hormones to stimulate the underactive thyroid gland.
An underactive thyroid gland cannot produce normal levels of T4 in the body.
Symptoms: Fatigue and weakness, cold intolerance, weight gain and puffy appearance, hair thinning, dry skin, decreased concentration, poor memory, muscle and body aches etc.
Treatment
: Hormone replacement therapy with levothyroxine
The right answers are 5 and 6.
The somatic nervous system is part of the peripheral nervous system <u>(part of the nervous system consisting of nerves and ganglia, and whose essential role is the transmission of information between the central nervous system - brain and spinal cord - and organs)</u>. It intervenes in the voluntary control of movements (or involuntary movements in case of reflexes, but this is different from the involuntary activities) (efferent fibers) and in the perception of external stimuli (afferent fibers).
The somatic nervous system controls the movements of skeletal muscle (which are generally voluntary) and the environmental perception, (think to the arc reflex).
The involuntary activities (proposition 1) mean automatisms like the heartbeat, respiration, secretions of hormones or sweat...
