Lysosomes are membranous organelles that contain digestive enzymes. lysosomes can function inside the cell, where their enzymes digest particles taken in by endocytosis or worn‑out cell components. lysosomes can also release their enzymes outside the cell, where the enzymes break down extracellular material. i‑cell disease is a lysosomal storage disease that results in the buildup of carbohydrates, lipids, and proteins as inclusion bodies within the cell. which is the probable cause? the cell does not take up food molecules by endocytosis. the golgi apparatus cannot target the appropriate enzymes to the lysosome. lysosomes accumulate extra lipid‑digesting enzymes. the lysosome cannot fuse to the cell membrane to release enzymes extracellularly.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

idk what happened..you tell
