Answer:
The correct answer is "True".
Explanation:
Some species of jellyfish use a form of jet propulsion to swim and get around the sea. For instance, the jellyfish <em>Polyorchis penicillatus</em> contracts its subumbrellar swimming muscles to gain power, which it uses as mechanical energy to perform a jet cycle while swimming. Some studies in this regard have been performed, measuring even the amount of energy needed in the muscles for the jellyfish to swim.
Photosynthesis I think im not 100% sure beb
Answer:
Option C
Explanation:
Long term hunting has led to following
a) Reduction in population size and hence the gene pool
b) Causation of Bottleneck effect
Due to above factors, the remaining population of Northern elephant seals does not represent the original genetic problem.
Due to this restriction in mating and genetic variation shall prevail pertaining to reduced gene pool.
Due to continuous hunting, the gene pool will further shrink, leading to genetic similarity among the organism
Option C is correct
One example is the country of Iceland which is a large island right on the mid-Atlantic ridge which is where the Atlantic oceanic plate is rifted in two and where the underlying magma wells up to the surface as the two sides to the plate move opposite to each other. The resulting volcanic rock then builds itself up into an island.
I think simple diffusion is a former of active transport
