Imagine the year is 2187 and Mars has become a bustling hub of activity. Humans have been living on the red planet for over a century, and the once-barren landscape is now dotted with cities and towns!
Dug into the ground and in perfect unity with the Dahar highlands of Southern Tunisia, the Matmata troglodytes homes are an otherworldly architecture and travel...
Вот такие чудовища у нас завелись (настолько фотогеничные, что даже фотографию в моём исполнении с небольшой натяжкой можно назвать приемлемой): Может съёживаться в почти равносторонний треугольник, так что с непривычки только по цвету можно понять, что это один и тот же вид. Судя по…

Mitochondria are the powerhouses of our cells. They create the cellular energy that allows us to think, move, eat, talk, breathe and everything else our bodies do. Along with creating energy as adenosine triphosphate (ATP), they also product heat.
Students will be able to read the description and decide if it's an Endothermic or Exothermic reaction.
Mycorrhizal fungi are beneficial soil organisms that attach themselves to the roots of plants and help them facilitate the uptake of water and nutrients.
cross section: Medicago stem common name: Alfalfa magnification: 400x Berkshire Community College Bioscience Image Library Like most herbaceous dicots, Medicago is capable of limited amounts of secondary growth. The uniseriate and cutinized epidermis contains trichomes and occasional stomata. The narrow cortex consists of an outermost hypodermis of up to four or five layers of chlorenchyma with areas over stem ridges being strengthened with collenchyma.The middle cortical layer consists of a zone of loosely arranged parenchyma and the deepest layer, of a band of endodermis (starch sheath) that follows the contours of the underlying vascular bundles. Within the stele the vascular bundles are arranged in a ring and separated from each other by wide medullary rays of parenchyma cells. The collaterally arranged vascular bundles are almost entirely primary phloem and xylem. Each bundle consists of a large outer supportive cap of sclerenchyma fibers (phloem fiber cap), a deeper layer of primary phloem with well-defined sieve tubes and companion cells, and a deepest layer of primary xylem. In between the xylem and phloem, a narrow band of cambium may be seen. In some preparations, the highly lignified cells walls of xylem and mature sclerenchyma are stained red orange. These cells are dead at maturity and can also be distinguished by a heavy cell wall and absence of cytoplasm. The center of the stem is occupied by a large pith of parenchyma cells that contain numerous starch storing amyloplasts. Technical Questions:[email protected]
