Explanation:
A hypothesis is a question that you test through study and experimentation. Basically a hypothesis is an educated guess that you attempt to prove write(it could be wrong) through an experiment
Disruptive selection or diversifying selection describes the changes in population genetics where extreme values for a trait are favored over intermediate values.
So according to this definition, the conclusion can be derived as :
The most common circumference(s) to be after 10 generations of diversifying selection will be greater than 2 cm and less than 2 cm.
Answer:
Cells divide twice
Explanation:
Meiosis may be defined as the process of cell division in which a single cell divides to give four daughter cells and each daughter cells have half number of chromosomes.
Meiosis is also known as reduction division as the chromosome number reduces upto half in the progeny cells as compared with the parent cell. The cells divide twice in meiosis and give rise to four daughter cells.
Thus, the correct answer is option (4).
Answer: what are you asking in this question?
Explanation:
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.
