Answer:
your joints, stretch the joint capsule. Gas is rapidly released, which forms bubbles.
Explanation:
Other molecules such as proteins, starch and sugar are simply too large to diffuse across the membrane. Sometimes, some of these large molecules are transported across the cell membranes by carrier proteins; this does not require energy and as a result is a form of passive transpor
Answer:
a. Excretion is accomplished by paired protonephridia with flame cells in every segment of the body. True
Most anelids have structures called metanephrids or protonephridia. Both structures are homologous to the kidneys and have the function of excresion, A pair are present in every segment of the body.
b. If the organs in one segment fail, the organs of another segment will still function. False
It is false because all segments are interrelated and have different functions depending on their location.For example, the first segment is where the sensory appendages are, such as the antennae and the eyes. The second segment is where the mouth is. There are a series of parapod segments to move, collectively called metameres and ends in a terminal portion called pigidium, where the anus is located.
c. Annelids possess both circular and longitudinal muscles that produce waves of contraction that are propagated down through the points eBookseries of segments.True
True because anelids have circular and longitudinal muscles that serve to function the hydrostatic skeleton.
d. Segmentation has allowed for specialization in the anterior of the annelid body, which has provided for a more sophisticated nervous system. True
True because the segmentation allows to have a nervous system formed by a ventral nerve cord provided with ganglia and lateral nerves in each segment.
It depends on the period. It could be Catherine the Great.
The answer is <span>microorganisms have rapid cell cycle.
Microorganisms are much simpler and much smaller organisms than humans. Because of their size and complexity, they reproduce in extremely rapid pace. For example, E. coli population is able to double each 20 minutes. This is, of course, not the case with humans.
For the mutation to become established, there must pass a few generations. So, if a useful mutation establishes in E. coli cell, in 20 minutes it will be present in the next generation, in 40 minutes it will be present in the generation after that, and so on. In the humans, years (not minutes) are necessary for the mutation to be passed down to the first generation. It needs less time to establish a mutation in E. coli than in humans.</span>
