C is the the correct answer
Autonomic nervous system (ANS) is the branch of the nervous system that provides unconscious control of basic body processes that is consists of two divisions; the sympathetic and parasympathetic. These two divisions have opposing effects on the internal organs they innervate. The Parasympathetic nervous system is the division that balances the actions of the sympathetic nervous system by slowing body processes, returning the body to homeostasis once a stressor has passed. The Sympathetic nervous system is the emergency system. Its major function is the fight-or-flight response in reaction to a threat. It speed-up key body processes to prepare the body for physical action.
Answer:
The growth rate is 1250 per year.
Explanation:
- First of all, lets consider the population number in both years;
The initial population is 1200, and
Final population is 3700.
- Total increased population is (3700- 1200) = 2500
So 2500 population were increased in (2006 - 2004)= 2 years.
- To find the annual growth rate: (Increased population/ time span in years)= 2500/2= 1250 per year.
- Hence 1250 population was added per year in walleye from 2004 to 2006.
Answer:
1. mutualism
2. parasitism
3. symbiosis
Explanation:
Mixotricha paradoxa forms symbiotic relationships (Symbiosis is a relationship between two or more organisms that live closely together) with the termite.
Part of the morphological characteristics of the Mixotricha paradoxa are the presence of "at least two kinds of bacteria attached to its outer surface." This morphological characteristics assist the termites in alot of ways. One of this kind of he spirochete propels its host through the termite gut. A second type of bacteria synthesizes ATP, some of which is used by the spirochetes. The locomotion provided by the spirochetes introduces the ATP-producing bacteria to new food sources. (mutualism)
Mixotricha paradoxa helps to digests cellulose for the termite. We can now conclude that Mixotricha forms a mutualistic relationships (mutualism) with bacteria living inside the termite. This is because the termite has spherical bacteria inside the cell which function as mitochondria, which Mixotricha lacks.
The Mixotricha are also organized into layers of tissue. Without their presence in the termite gut, the termites would die because Mixotricha keep the species intact, but they are harmful in an indirect way (parasitism).
Character displacement – trait evolution stemming from selection to lessen resource competition or reproductive interactions between species – has long been viewed as an important mechanism for enabling closely related species to coexist.
