Answer:
Compared to the small, isolated population on Isle Royale, in the national park diseases like parvovirus are less likely to be a problem, and lack of genetic diversity is less likely to be a problem for the wolves.
Explanation:
Diseases like parvovirus and lack of genetic diversity are less likely to be a problem for wolves in national park as ecologists are protecting them there.
Compared to the small, isolated population on Isle Royale, in the national park diseases like parvovirus are less likely to be a problem, and lack of genetic diversity is more likely to be a problem for the wolves.
There is a balance that exist between wolves and moose in Michigan's Isle Royale National Park.
Wolves was known to first colonized Lake Superior's Isle Royale in the late 1940s.
Wolves lives eating old or sickly moose. Studies has shown that the wolf population had swelled to 24, a surprisingly large number and 80% of the island's moose had died
Parvovirus is a disease that inflames the wolf's intestines and causes death by diarrhea within 24 hours. It was introduced to the island in 1981 by a visiting dog as studies says and killed nearly half the wolves and thereafter it disappeared.
Peterson a scientist says this disease is unlikely to have killed wolves now, as survivors of the last outbreak must have acquired immunity.

A flask containing photosynthetic green algae and a control flask containing only water are exposed to a cycle of 12 hours of light and 12 hours of darkness. Which of the following statements best describes how the relative dissolved oxygen concentration in the flask with algae will compare to the control flask?
A. The dissolved oxygen in the flask with algae will not be different from the control flask at any time.
B. The dissolved oxygen in the flask with algae will always be higher.
C. The dissolved oxygen in the flask with algae will be higher in the light, but lower in the dark.
D. The dissolved oxygen in the flask with algae will always be lower.
E. The dissolved oxygen in the flask with algae will be higher in the light, but the same in the dark.
The option that correctly describes the relative dissolved oxygen concentration in the flask with algae will compare to the control flask is C. The dissolved oxygen in the flask with algae will be higher in the light but lower in the dark.
What factors can increase the amount of dissolved oxygen in water? Temperature, pressure, salinity and biological organisms are the major contributing factors that affect dissolved oxygen. If the medium contains a photosynthetic plant that too in the presence of light, then this will increase the dissolved oxygen. On the other hand, increased salinity and warm water decrease the amount of oxygen dissolved in water. As given above, the flasks containing the green algae and water are given 12 hours of light and then put 12 hours in darkness. The flask that contains the algae contains more dissolved oxygen during the light hours as algae are photosynthesis in nature and thus, they will do photosynthesis during 12 hours of lighting. But, the control flask contains only water and thus, there will be no addition of dissolved oxygen.Thus, we can conclude that flask that contains algae have more amount of oxygen dissolved than the control flask containing only water. During 12 hours of darkness, no photosynthesis occurs and hence algae containing flask will have a lower amount of dissolved oxygen.

Serotonin (5-hydroxytryptamine, 5-HT) is a neurotransmitter with receptors (5-HT receptors) located in cells throughout the body.
a. True
b. False
Answer:
a. True
Explanation:
Serotonin receptors are G protein-coupled receptors involved in the modulation of both excitatory and inhibitory neurotransmission. Serotonin receptors are divided into seven classes (5-HT1 to 5-HT7) which can be in turn divided into several subclasses (A, B, C, etc.). Most of the serotonin receptors are located in the gut (about 90%), but they are also spread in other parts of the body, including the amygdala, the bed nucleus of the stria terminalis (BNST, also known as the extended amygdala), Merkel cells (skin), taste receptor cells (tongue), Raphe nuclei (brainstem), etc.

Answer:
1. Diverging circuit.
2. Parallel after-discharge circuit.
3. Reverberating circuit.
4. Diverging circuit.
5. Converging circuit.
Explanation:
A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.
Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.
Generally, the nervous system found in living organisms such as humans, comprises of two (2) major components or systems; a central nervous system (CNS) and a peripheral nervous system (PNS).
A neural circuit can be defined as a group of neurons in the body of a living organism which are interconnected by synapses to perform specific functions when they're activated.
There are four (4) main types of neural circuits used for performing specific neural functions in the body of a living organism, these includes;
1. Diverging circuit: one incoming axon triggers responses in ever-increasing numbers farther and farther along the circuit. For example, a neuron that stimulates thousands of cells such as sensory pathway to the central nervous system (CNS).
2. Parallel after-discharge circuit: may be involved in complex, exacting types of mental processing. For example, it used in reflex arcs, mathematics and logic.
3. Reverberating circuit: involved in control of rhythmic activities such as breathing and as such it's repetitive in nature. For example, short-term memory, sleep cycle, etc.
4. Diverging circuit: involved in activating fibers of a skeletal muscle such as the biceps muscle.
5. Converging circuit: different types of sensory input can have the same ultimate effect. For example, the regulation of the somatic motor neuron.

A burning of fossil fuels
B geothermal energy
If both the locations produce the same amount of energy, which of these statements best describes the difference between the two locations?
Location A experienced higher installation costs for energy than Location B.
Location B experienced higher installation costs for energy than Location A.
Location A uses a lesser amount of electricity than Location B.
Location B uses a lesser amount of electricity than Location A.
