While studying for your physical anthropology midterm, your classmate tells you that the bones of Lucy, a famous australopitheci

ne specimen that dates to about 3.2 million years ago, were dated based on carbon-14 analysis. You note that this is incorrect because
Fossils are living organisms that have wholly or partially been transformed into rock. Lucy does not have bones with organic material necessary for carbon-14 dating. This specimen is also far too old for C-14 dating to be accurate, as well as for any other technique but palaeomagnetic dating. Your classmate is therefore incorrect for all of the reasons listed. (All of the above) (T/F)

Explanation:

The second part of the sentence is not accurate, since the remains were dated by uranium-lead dating. Carbon-14 dating measures ages in the tens of thousands of years, and uranium-lead dating measures in the millions to billions of years.

Answer:

This suggests that the moustache is a releaser for aggression.

Explanation:

<em>Fixed action patterns</em> are instinctive programmed responses in different species that are triggered by a specific external sensory stimulus. These stimuli are called sign stimuli or releaser. When the sign occurs, the animal starts a sequence of acts in response to the stimulus and continuous until the series of actions is completed.

The black feathers resembling a mustache in a <em>Northern flickers</em> male are an external sensory stimulus. This trait that can provoke another male to respond aggressively, as a f<em>ixed action pattern</em>.  

This trait might be considered as an <em>unconditioned stimulus</em>, which <em>provokes an unlearned or reflex reaction</em>. These aggressive responses are triggered by reflex.

<span>D. all systems work together to maintain homeostasis.

</span>Its not actually just one system if you look at it, there are various interdependent system that actually manages every movement of every system in order to maintain homeostasis, plainly every set function is a coordinated body system response. For example, the digestive system digests food because of the enzymes and the cells and organs present in its system but again, this is aided by the different hormones which is part of the endocrine system, interdependently. Thus eventually, the circulatory system is the organ system that intiates in dissemination of the different processed and intially metabolized nutrients in the digestive system and sent throughout the body. Incidentally, also the immune system acts as agent in again many systems to maintain the so-called homeostasis.
