The infant is suffering from dehydration most probably from esophageal atresia (non-development of the distal side of the esophagus, forming a closed tube) or partial/complete gut obstruction. With a urine output of 250 mL constantly, the patient will be dehydrated. The infant is diagnosed with failure to thrive and is most probably malnourished (most common cause of failure to thrive in infants is preterm birth). In the presence of esophageal atresia, along with retained feedings, the patient will also present with vomiting. In the presence of partial/complete gut obstruction, the patient will also present with distension of the abdomen.
Answer: Option C) proximal convoluted tubule
Explanation:
The nephron has the proximal tubule where some water, amino acids and salts which are useful to the body are reabsorbed into the blood capillaries against concentration gradient by active transport.
Thus, the process of selective reabsorbtion takes place in the proximal convoluted tubule
Answer:
Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.
Answer:
Vagus nerve
Explanation:
Vagus nerve is the tenth cranial nerve that can innervate in the neck, thorax and abdomen.
Thyroid gland is located below the neck region and releases thyroxine hormone. Vagus nerve innervates in the thyroid gland. Parasympathetic fibres of thyroid gland comes from the vagus nerve and symapthetic fibres is distributed in the superior, middle and inferior ganglia of sympathetic trunk of the thyroid gland.
Thus, vagus innervates in the thyroid gland.
Answer:
Explanation:
While passing through renal tubules, water and a lot of other substances are reabsorbed making filtrate concentrated. This also gradually results in an increase in the concentration of urea as it is not reabsorbed like water or glucose. Some substances like K+, H+ are also secreted (not urine).
