Answer:
the life cycle of a frog consists three stages : first stage is egg and second stage is larva and the final stage is adult
Answer:
Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.
Explanation:
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.
There are 2 main hormones that can control blood glucose levels : insulin and glucagon.
Both of them are produced in the pancreas.
If the blood glucose level is too high, insulin can help by converting glucose into glycogen, the storage form of carbohydrates.
If the blood glucose is too low, glucagon can covert glycogen back into glucose to increase blood glucose level. Both of these hormones can work together to control blood glucose level in body.
Answer:
The answer is reciprocal chromosomal translocation
Explanation:
The Philadelphia chromosome (Ph) is the truncated chromosome 22 generated by the reciprocal translocation t(9;22)(q34;q11) and was first identified in 1960 in a patient with CML [3]. Translocation of the proto-oncogene tyrosine-protein kinase (ABL1) gene located on chromosome 9 to the breakpoint cluster region (BCR) gene located on chromosome 22 results in a BCR-ABL1 fusion gene on the Ph [4, 5]. Three BCR-ABL1 fusion gene hybrids encode BCR-ABL1 protein isoforms p210, p190, and p230, which have persistently enhanced tyrosine kinase (TK) activity. These aberrantly activated kinases disturb downstream signaling pathways, causing enhanced proliferation, differentiation arrest, and resistance to cell death [6, 7]. Tyrosine kinase inhibitors (TKIs) targeting the BCR-ABL1 protein are the most successful targeted therapy for Ph-positive leukemia.
Answer:Trees and other green plants are the source of energy for all animal life to live and grow. Through the process of photosynthesis plants change light energy from the sun into chemical energy that is stored in the plant as carbohydrates (sugars) as it grows
