Answer:
mass doubled makes KE twice as large
velocity doubled makes KE 4 times as large
Explanation:
Try it with an example
m = 4
v = 8
KE = 1/2 m * v^2
KE = 1/2*4 * 8^2
KE = 1/2 * 4 * 64
KE = 128
Now double the mass
m = 8
v = 8
KE = 1/2 8 * 8^2
KE = 1/2 8 * 64
KE = 4 * 64
KE = 256 double what it started out as.
Now do it again.
m = 4 That was the original mass
v = 16
KE = 1/2 4 * 16^2
KE = 2 * 256
KE = 512
When the velocity is doubled the KE becomes 4 times as big.
4*128 = 512
Explanation:
Low power objective shows more field of view but does not give appreciable details about the view.
- In the root tip of onions, the cell walls are distinctly visible and they are arranged in a rectangular mosaic pattern.
- The nucleus stands out appreciably and it is tiny.
- The cytoplasm is also visible.
- Root cells do not have chloroplast since they do not take part in photosynthesis.

Answer:
Answered below
Explanation:
On piercing his foot, the pain receptors called nociceptors, found in the skin, are activated. Nociceptors exist at the nerve endings of the primary afferent neurons. Signals travel along the first order neurons which have cell bodies within the dorsal root ganglia of the spinal cord. In the dorsal root ganglia, the signals are taken up at the synapse with the second order neurons which have cell bodies in the nuclei of the cranial nerves within the brainstem. These neurons ascend cranially in the spinothalamic tract to the thalamus. The third order neurons lie within the ventral posterolateral nucleus of the thalamus. They terminate at the somatosensory cortex where the signals are being processed and returned as a sensation of pain.
Answer:
Adaptive radiation
Explanation:
Adaptive radiation refers to the evolution of the multiple species from one ancestral species. The force which drives the formation of new species is the change of natural environment like the availability of resources, niche, and many other related changes.
The species adapt themselves to these changes and get transformed into new species.
The formation of a variety of species of finches on the Galapagos island is an example of adaptive radiation. The species formed as a result of the food resources they received on the island.
Thus, Adaptive radiation is the correct answer.
