The Burgess Shale is a rock formation that is known for having an abundance of soft bodied organisms preserved in shale. This formation is significant because it preserves organisms from the Cambrian Explosion. The Cambrian Explosion is a period in time that coincides with the Pre- Cambrian- Cambrian boundary around 542 million years ago. The period represents an unusually rapid radiation of organisms. 
Fossils of the Burgess Shale are thought to be well preserved because most were thought to be buried fairly rapidly and in conditions that had little or no oxygen. The rate of decomposition is slowed in these conditions so soft body parts of the organisms were preserved for millions of years in the mud-stone that eventually became lithified to shale. <span />

Answer:

I can tell you now that its definitely not D., C, or E. However, I'd debate that it'd be either A. or B.

Me, I'd go with b, but it could be either a or b.

Altruism has NOTHING to do with bee's as it is the belief of putting yourself aside for the well-being of others, but in biology, it refers to behavior by an individual that increases the fitness of another individual while decreasing the fitness of the actor.

Hearing has NOTHING to do with the reproductive system.

Nothing is to too small to have functional ears.

D,E, and C don't make sense.

Oksi-84 [34.3K]

Answer:

Flaccid paralysis.

Explanation:

Demyelinating disease may be defined as in which the protective layer of myelin sheath gets damaged. This causes the slow down or even stops the transfer of nerve impulse.

Flaccid paralysis is the neurologic condition that results in the reduced muscle tone due to damage in the nerves of the muscles. The contraction is inhibited in the flaccid paralysis. The demylination results in no contraction at all as occur in flaccid paralysis.

Thus, the answer is flaccid paralysis.

What type of behavior was among the first to evolve among the earliest(most primitive) animals?
Vlad [161]

Solution:

Primitive animals are ones that have not changed dramatically over the millennia and remain very similar to their ancestors.

The first members of the human lineage lack many features that distinguish us from other primates. Although it has been a difficult quest, we are closer than ever to knowing the mother of us all. Until recently, the evolutionary events that surrounded the origin of the hominin lineage — which includes modern humans and our fossil relatives — were virtually unknown, and our phylogenetic relationship with living African apes was highly debated. Gorillas and chimpanzees were commonly regarded to be more closely related to each other due to their high degree of morphological and behavioral similarities, such as their shared mode of locomotion — knuckle-walking. But with the advent of molecular studies it has become clear that chimpanzees share a more recent common ancestor with humans, and are thus more closely related to us than they are to gorillas (e.g., Bailey 1993, Wildman et al. 2003). The similarities between the living African apes were thought to have been inherited from a common ancestor (=primitive features), implying that the earliest hominins and our last common ancestor shared with chimpanzees had features that were similar, morphologically and behaviorally, to the living African apes (Lovejoy 2009). With the discoveries of the earliest hominin species discussed below, it is now possible to critically examine these assumptions.

horsena [70]

The answer is: 200kcal

Physical activities will cause the muscle to burn more calorie. A child that more physically active would need more calorie to supply the energy need of the muscle. Ryder participate in many physical activities most of the days of the week, so the physical activities would be around moderate to very active. The upper limit of calorie addition for moderately active child would be 200kcal.

Plants and animals are both _____.
kolezko [41]
Plants and animals are both "organisms" or "living organisms" if you prefer.

An organism is basically a group of different organs functioning together (hope this was the easiest way to explain it).

Hope it helped,

Happy study/ homework/ exam!
