An enzyme that can stimulate germination of barley seeds is:
- \(\alpha\)-amylase
- lipase
- protease
- invertase
The Correct Option is A
Solution and Explanation
An enzyme that can stimulate the germination of barley seeds is \(\alpha\)-amylase, which breaks down starch into simpler sugars to provide energy for germination.
So, the correct option is (A): \(\alpha\)-amylase

From these pieces, two equivalent resistances are made by adding four of these together in parallel. Then these two are added in series. The net effective resistance of the combination is:

- The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant \(K_1\) and \(K_2\) with thickness \(d/2\) and \(d/2\) respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If \(K_1 = 1.25 K_2\), the value of \(K_2\) is :

Circulatory Pathways
Virtually every cell, tissue, organ, and system in the body is impacted by the circulatory system.
- Digestive - Absorbs nutrients and water; delivers nutrients (except most lipids) to liver for processing by hepactic portal vein; provides nutrients essential for hematopoiesis and building hemoglobin.
- Endocrine - Delivers hormones: atrial natriuretic hormone (peptide) secreted by the heart atrial cells to help regulate blood volumes and pressures; epinephrine, ANH, angiotensin II, ADH, and thyroxine to help regulate blood pressure; estrogen to promote vascular health in women and men.
- Integumentary - Carries clotting factors, platelets, and white blood cells for homeostatis, fighting infection, and reparing damage; regulates temperature by controlling blood flow to the surface, where heat can be dissipated; provides some coloration of integument; acts as a blood reservoir.
- Muscular - Provides nutrients and oxygen for contraction; removes lactic acid and distributes heat generated by contraction; muscular pumps aid in venous return; exercise contributes to cardiovascular health and helps to prevent atherosclerosis.
