Answer:
Endocrine and Circulatory system
Explanation:
Endocrine releases horomones while circulatory circulates blood around the body. The hormones are transported around the body in blood.
Answer:
False
Explanation:
Lysosomes are indeed membranous sacs that contains hydrolytic enzymes as rightly stated in this question i.e. enzymes that breakdown substances. They are cellular organelles that perform digestive functions due to the high content of digestive enzymes in them.
However, hydrolytic enzymes in the lysosomes do not function to produce hydrogen peroxide, H2O2, as a product. This function occurs in PEROXISOMES, another organelle with similar function to the lysosome but differs in the sense that it produces and decomposes hydrogen peroxide.
Explanation:
A good surfactant is going to have a hydrophilic head and a long hydrophobic tail. As a result, a surfactant molecule contains both an insoluble water (or an oil-soluble component) and a water-soluble component. Surfactant molecules will migrate to the surface of the water, where the insoluble hydrophobic group may extend out of the bulk phase of the water, either into the air or, if the water is mixed with oil, into the oil Phase, while the water-soluble head group remains in the water phase. This alignment and aggregation of surfactant molecules at the surface is intended to alter the surface properties of water at the water / air or water / oil interface.
Danish scientist Hans Christian Gram devised a method to differentiate two types of bacteria based on the structural differences in their cell walls. In his test, bacteria that retain the crystal violet dye do so because of a thick layer of peptidoglycan and are called Gram-positive bacteria. In contrast, Gram-negative bacteria do not retain the violet dye and are colored red or pink. Compared with Gram-positive bacteria, Gram-negative bacteria are more resistant against antibodies because of their impenetrable cell wall. These bacteria have a wide variety of applications ranging from medical treatment to industrial use and Swiss cheese production.

<em>Clastic sedimentary rocks are made up of pieces of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock</em>
