Autophagy  is a catabolic process in eukaryotic cells that delivers cytoplasmic components and organelles to the lysosomes for digestion. Lysosomes are specialized organelles that break up MACROMOLECULES, ALLOWING the cell to reuse the materials.Explanation:The lysosome or vacuole is the major catabolic factory in eukaryotic cells and contains a range of hydrolases capable of degrading all cellular constituents. Organelle turnover is accomplished EXCLUSIVELY at this location through a process of autophagy that is conserved among yeast, plant, and animal cells.Autophagy is mediated by a unique organelle called the AUTOPHAGOSOME. As autophagosomes ENGULF a portion of cytoplasm, autophagy is generally thought to be a nonselective degradation system

ment of the ORIGINAL heart part or events of tissue of the organism by minerals is known as petrificationOption 2Explanation:Petrified FOSSILS are made up from  the process known as permineralisation, which is the replacement of once-living organisms by minerals.When minerals substitute the structure of an organism, petrified fossils form. This process is known as permineralisation, that is when groundwater solutions saturates the REMAINS of plants and animals that have been buried.When water evaporates, the minerals would remain and will FINALLY occupy the spaces remaining as the organism gradually decaysTo know more,A person is bound to INSURE himself against all types of losses------- a ...brainly.in/question/8665832

tion: The number of chromosomes is even because we are diploid: there are 23 TYPES of chromosomes, and we inherit one of each type from each parent. Diploidy has some advantages, most importantly allowing COMBINATION of DIFFERENT genetic sources during sexual reproduction, and the ABILITY to repair DAMAGES in one chromosome using the other as a template.

cell (from Ancient Greek σῶμα sôma, meaning "body"), or vegetal cell, is any biological cell forming the body of an organism; that is, in a multicellular organism, any cell other than a gamete, germ cell, GAMETOCYTE or undifferentiated stem cell.[1]In contrast, gametes are cells that fuse during sexual reproduction, germ cells are cells that give rise to gametes, and stem cells are cells that can divide through mitosis and differentiate into diverse specialized cell types. For example, in mammals, somatic cells make up all the internal organs, skin, bones, blood and connective tissue, while mammalian germ cells give rise to SPERMATOZOA and ova which fuse during fertilization to produce a cell called a ZYGOTE, which divides and differentiates into the cells of an embryo. There are APPROXIMATELY 220 types of somatic cells in the human body.[1]
