We developed Natural Earth as a convenient resource for making custom maps. Unlike other map data intended for scientific analysis or military mapping, Natural Earth is designed to meet the needs of production cartographers using a variety of software applications. Maximum flexibility is a goal. Natural Earth Vector comes in ESRI shapefile format, the de facto standard for vector geodata.
A gizzard is a sack like organ at the back of the earthworms throat. The gizzard basically chews the earthworm's food since the worm doesn't have any teeth. The crop is a thin â¦ ner organ closer to the head. The crop stores food.
Soybean seed germination is referred to as âepigealâ because food storage structures (cotyledons) are pulled above the soil surface. In contrast, corn germination is considered âhypogealâ because the storage structure remains below the surface when the seed germinates. Figure 1.
