Answer:
A zoospore is a motile asexual spore that uses a flagellum for locomotion. Also called a swarm spore, these spores are created by some protists, bacteria and fungi to propagate themselves.
Explanation:
300 BC by Greek philosophers
The species was a keystone species.
Keystone species are the species that ''hold the ecosystem together''.
They have an important role in the trophic networks (food chains) and often they can even afflict changes in the abiotic part of the ecosystem (change the composition of soil, purify the water, lower the effect of the wind etc)
Therefore, when a keystone species is removed it affects greatly the whole ecosystem.
Answer:
Explanation:
Law of conservation of energy states that energy can neither be created nor destroyed. Thus, in relation to the question, as the object slides down the ramp, the kinetic energy should increase at the same rate the potential energy is reducing in such a way that the kinetic energy of the object at the bottom of the ramp should be equal to the potential energy of the object at the top of the ramp (since the energy was been "transferred" as the object moved). However, this situation only occurs, as explained, in the absence of friction. <u>In the presence of friction, some of the energy is used to overcome friction as the object moves down the ramp and as such there is an energy loss due to friction in the process which makes the kinetic energy at the bottom of the ramp not equal to the potential energy at the top. This also does not violate the law of conservation of energy since no energy was destroyed in the process (as all the energy involved can be accounted for)</u>.
Need picture sorry this wont help me
