Answer: a light microscope is likely the answer they are after (can get to micrometer range)
an electron microscope is even more powerful it can get into the nanometer range
Explanation:
Answer:
Both physical and chemical weathering, along with erosion, can change Earth's surface as physical weathering allows breakdown of rock into smaller pieces, these pieces can be move from one place to another through water, wind or ice (erosion), and when the smaller pieces will settle down at a place, rain water can react with the soil or smaller rock pieces to form rock minerals.
For example: Running water, wind, and rapid heating/cooling allows the rocks to break down into smaller pieces or grains (physical weathering), then the small grains are transported and settled away from the source area through wind or river (erosion), and at the end the surface area exposed to air for chemical weathering.
2 abiotic(non living) limiting factors are water(A) and food(B)
Answer:five types of bones in the skeleton: flat, long, short, irregular, and sesamoid.
Explanation:
The growth of lymphoid tissue in the gut is fueled by TNFa. Because TNF/Rorc(gt)/ mice, who express higher amounts of TNF but lack RORgt+ LTi cells, also generate lymphoid tissue in sites of inflammation, the development of this ectopic lymphoid tissue was not contingent on the presence of conventional RORgt+ LTi cells. Surprisingly, these animals produced a number of lymph nodes that resembled those of wild type animals in both structure and function. When stromal cells were activated during the late stages of embryogenesis and when an organogenic pathway that permitted the formation of lymph nodes was activated, TNF generation by F4/80+ myeloid cells located inside the anlagen was crucial.
