Answer:
Glossopteris and Lystrosaurus
Explanation:
Glossopteris is an ancient plant flora and Lystrosaurus is a fossil fauna, and both are found in many of the landmasses on earth. The Glossopteris flora appeared about 300 to 200 million years back and the Lystrosaurus appeared about 250 million years back on earth. They both existed from the time of late Permian to early Triassic age.
Both these fossils played an important role in understanding the continental drift theory or the plate tectonic theory. This evidence enabled geologists to understand how the continents have moved across the large ocean basin from one place to another and at what rate they are drifting currently. It helped in understanding how the super-continent Pangaea had broken into Laurasia and Gondwanaland, and further broken into the present location of the plates.
Answer: There is presence of tumor.
Explanation: The adhesion of cells to extracellular matrix (EMC) through integrins ( cell-EMC binding molecules, which are collagens, laminins and fibronectin) causes the activation of kinases in the cytoplasm.
However, kinanes helps in controlling the epithelial cell differentiation and upholding the epithelial tissues. This is done by the addition of phosphate groups to a substrate protein which is termed Protein phosporylation. Then, the kinases direct the affairs of the cell and it's activities. For example, it determines the cell division, anabolic and catabolic activities of the cell, movement of ions between the cell and it's environment (signal transduction), protein functions and etc.
Conclusively, since the activities of the cell like cell division and protein functions is dictated by the kinase, reduction in cell division that gave rise to rapid growth is put on hold. Hence, the tumor is been suppressed.
Note: the binding of cell-EMC is regulated by Transforming Growth Factor (TGF) β.
Answer:
These fossils looks as if they belong to a whale or a tiger you can tell by the skull structure. but alas look at a hippopotamus skull. they look dangerous.
Explanation:
Answer:
increase protection and communal conservancies
Explanation:
increase protection this one is a fairly basic solution, there are many different ways of implementing it. Some park protection agencies in Africa use drones to keep watch at night, while others have sought out military tactics in order to stop black market poachers. Communal conservancies despite global trends, Namibia has done something extraordinary. Between the years of 2002 and 2013, the elephant population has grown from 9,600 to 16,000. The government of Namibia has policies in action where local communities can establish wildlife tourism, and where communities can keep vast amounts of the revenue made.
