Early cleavage divisions in most embryos are also rapid. One reason for this is that cleaving cells have a modified cell cycle, in which the two gap phases, G1 and G2 are completely omitted, and the cells cycle rapidly between M and S phases. In addition, because the major cytoskeletal systems of the cells are largely devoted to mitosis (microtubules) and cytokinesis (microfilaments) during rapid cleavage division, there is typically an antagonism between periods of rapid cell division and cell movement. Thus as the embryo approaches gastrulation, there is a tremendous slowing in the rate of division (note the slope of the curve at the right).
The Neisseria gonorrhoeae bacteria which responsible for Gonorrhea, a sexually transmitted disease. Aside from the usual symptoms of gonorrhea like vaginal and penile discharge it also includes skin dermatitis with pustular or papule like lesions which are located in visible areas.
Answer:
tundra, taiga, temperate grassland, rainforest
Explanation:
Tundra is known to be the coldest of all the biomes due to the high latitudes in which these areas are found. In this biome, the growth of the trees is limited by the low temperatures and the growing season is restricted to the summer season. The taiga is a type of biome composed of forest found in the subarctic areas, it is for that reason that taiga regions are also called boreal forests. Temperate grasslands are areas where grasses are dominant with very variable temperatures depending on the season (i.e. summer to winter seasons). In this biome, trees are relatively uncommon. Finally, the rainforest is the most diverse tree-rich biome where the high temperature and humidity conditions are optimal for life.
