The process that converts light energy into chemical energy in plants is:
A. Translocation
B. Fermentation
C. Respiration
D. Photosynthesis
Answer: Option D
Solution (By JKExamLibrary)
Photosynthesis captures light energy via chlorophyll and converts CO₂ and H₂O into glucose and O₂. Respiration releases energy from glucose, fermentation is anaerobic, translocation is movement of solutes.
Explanation:
Sponges are the simplest multicellular animals with a cellular level of organization (no true tissues or organs). They are mostly marine, sessile, filter feeders. Water enters through numerous pores (ostia) into a spongocoel and exits through the osculum. They lack a nervous system. They possess specialized cells like choanocytes and amoebocytes but no coordination.
Explanation:
GIP (glucose-dependent insulinotropic peptide) is released from the small intestine in response to fat and glucose, inhibiting gastric secretion and motility. Gastrin stimulates acid secretion, secretin stimulates bicarbonate, CCK stimulates gallbladder contraction.
Explanation:
The loop of Henle creates a concentration gradient in the medulla, enabling water reabsorption and concentrated urine. Urine is formed in kidneys, the unit is nephron, ureter connects kidney to bladder.
