Answer:
two main types tropical and temperate
Explanation:
There are two main kinds of grasslands: tropical and temperate. Examples of temperate grasslands include Eurasian steppes, North American prairies, and Argentine pampas. Tropical grasslands include the hot savannas of sub-Saharan Africa and northern Australia.
Answer:
If mitosis skipped any of the stages, it would result in a mutated cell. If the cell skipped Metaphase, it could make daughter cells that are different than the parent cells. If the cell skipped Telophase, the cell would not divide, and the parent cell would attempt interphase with another nucleus.
Explanation:
The cell cycle has two main phases, interphase and mitosis. Mitosis is the process during which one cell divides into two. Interphase is the time during which preparations for mitosis are made.
The chromosomes become more compact and tightly coiled. They are ready to separate. :)
Hope this helps!
THE EXCRETORY SYSTEM
Answer: The attachment shows the nephron which is the functional unit of the kidney.
It does the work of urine formation through 3 distinct processes.
-Ultra filtration( Small molecules are forced out of the selectively permeable membrane of the glomerulus into the Bowman's capsule under regulated pressure.these molecules are from the blood in the glomerulus brought in by the afferent arteriole.
- Selective reabsorption ( Useful molecule and iron such as glucose and sodium are reabsorbed back into the blood as the filtrate flows through the tubule(nephron)
-Tubular Secretion. ( Movement of molecules not filtered by the glomerulus during the initial stage of filtration back into the filtrate through the renal capillaries.
Stella's urine sample shows the presence of large protein (ULTRAFILTRATION)
John's blood test report indicates a high toxin level ( ULTRAFILTRATION AND TUBULAR SECRETION)
Miguel's blood test shows an increase in metabolic waste( ULTRAFILTRATION AND TUBULAR SECRETION)
Janice's urine report shows the presence of vital materials ( SELECTIVE REABSORPTION).
