A child grows up in a Bihari family and naturally learns to speak that language. Identify the language learned by the child in their family environment:

→ In the context of the relative roles and interaction of 'heredity' and 'environment' in child development, which of the following scientific viewpoints is most authentic and widely accepted by modern psychology? → What is the relationship between 'heredity' and 'environment' in a child's development called? → What does 'practical intelligence' mean in the Triarchic Theory of intelligence? → In the context of human development, while studying the interaction between heredity and environment, the concept of 'reaction range' explains that an individual's genetic makeup (genotype) establishes the upper limit of their intellectual or physical development, whereas the environment determines the point within that range the individual will actually reach. In relation to this scientific perspective, which of the following statements is most appropriate? → Consider the following statements regarding various glands of the human body and the hormones or enzymes secreted by them: 1. The pancreas is a heterocrine gland, whose endocrine part, the 'Islets of Langerhans', is made up of alpha, beta, and delta cells, where insulin, glucagon, and somatostatin hormones are secreted. 2. The pituitary gland is called the 'master gland', located in the sella turcica cavity of the sphenoid bone of the skull, and its posterior part (neurohypophysis) synthesizes and secretes oxytocin and vasopressin (ADH) hormones. 3. The primary function of the calcitonin hormone secreted by the thyroid gland is to lower calcium levels in the blood, while parathormone (PTH) secreted by the parathyroid gland increases the amount of calcium in the blood. 4. 'Catecholamines' (epinephrine and norepinephrine) hormones are secreted from the cortex part of the adrenal gland, which control the body's response in emergency situations (fight or flight). Which of the above statement(s) is/are completely true? → Consider the following statements regarding the various organs, systems, and hormonal and chemical control processes in the human body: 1. The 'pacemaker' (Sinoatrial Node or SA Node) in the human body is located on the wall of the right atrium, which spontaneously excites to generate electrical impulses and controls the contraction of heart muscles. 2. The Pancreas is a mixed gland whose 'beta cells' of the Islets of Langerhans secrete insulin, while 'alpha cells' secrete glucagon, which helps balance sugar levels in the blood. 3. The Nephron is the structural and functional unit of the Kidney, in which ultra-filtration of blood takes place through Bowman's capsule and glomerulus, and the Loop of Henle is mainly responsible for the concentration of urine. 4. The 'hypothalamus' part of the human brain is the major center for regulating hunger, thirst, temperature control, and hormones secreted by endocrine glands, while the Cerebellum controls body balance and voluntary muscle movement. Which of the above statement(s) is/are completely true? → Which of the following is not a factor affecting learning? → Which one of the following is a factor affecting the physical development of a child?
