Answer:
Basophils
Explanation:
Basophils are the granular leukocytes that make 0-1% of the total white blood cells. Basophils are 10–12 μm in diameter and are the spherical cells with lobed nuclei. When Wright stained, basophils appear to have large, irregularly shaped, deep-blue granules in their cytoplasm. These granules take up the basic stain and hence these cells are called basophils.
Basophils release histamine and heparin. Histamine is associated with allergic reactions. Histamine also dilates blood vessels and triggers contraction of smooth muscle. Heparin inhibits clotting and promotes blood flow. Together, histamine and heparin promote blood flow to injured tissues.
Answer:
fails to verify
Explanation:
An experiment that <u>fails to verify</u> a hypothesis will often provide a new direction for the researcher.
Researchers conduct experiments to develop hypotheses. A hypothesis is a testable and falsifiable explanation. A hypothesis can be tested. It is possible to prove the hypothesis as true or false.
An experiment is a way to test the hypothesis.

Past climate changes led to extinction of many species, population migrations, and pronounced changes in the land surface and ocean circulation. The speed of the current climate change is faster than most of the past events, making it more difficult for human societies and the natural world to adapt.
