The central nervous system includes all of the following except: brain spinal cord nerves that reach the tissues in limbs cerebellum
Answer:
My answer is the CNS consist of the brain and the spinal cord nerves but not cerebellum.
The nerves that reach the tissues in limbs is not the part of the central nervous system.
• The central nervous system or the CNS mainly is formed of the spinal cord and the brain. However, it generally is considered to exhibit seven fundamental parts, that is, the spinal cord, the pons, the medulla, the midbrain, the cerebellum, the cerebral hemispheres, and the diencephalon.
• The parts of the nervous system apart from the brain and the spinal cord is known as the peripheral nervous system.
• It comprises the spinal nerves, the cranial nerves and their roots and branches, the neuromuscular junctions, and the peripheral nerves.
• The bundles of axons or the nerve fibers transmit information to and from the central nervous system in the peripheral nervous system.
Thus, the nerves that reach the tissues in the limbs is the part of peripheral nervous system not central nervous system.

Using the formula in your notes, calculate the growth rate for a population of 1,200 with a carrying capacity (K) of 2,000 and a maximum per capita growth rate (rmax) of 0.3.
Answer:
The correct answer is : 144.
Explanation:
Given:
K or carrying capacity = 2000
N or population size = 1200
rmax or maximum per capita growth rate = 0.3
formula:
growth rate = [tex](rmax) (N) \frac{K-N}{K}[/tex]
Solution:
by the formula ,
growth rate =
[tex](0.3) (1200) \frac{2000-1200}{2000}[/tex]
= [tex]360 [\frac{800}{2000}][/tex]
= 360 × 0.4
= 144
Thus, the correct answer is : 144.

a hypothesis that has support to back it up and is yet to be disproved
Answer:
a theory
Explanation:
A hypothesis that has support to back it up and that is yet to be disproved can be referred to as a theory.
Ordinarily, a hypothesis is a tentative statement that has not been proven in any way. Once a hypothesis has supports to back it up and there are no counter-evidence to disprove it, it becomes a theory.
In other words, a theory is a proven hypothesis and it remains so until there are overwhelming evidence to counter the supporting evidence.

Which of the following can be attributed to water's high specific heat? O Oil and water do not mix well. O Alake heats up more slowly than the air around it. Ice floats on water. Sugar dissolves in hot tea faster than in iced tea.
Answer:
O A lake heats up more slowly than the air around it.
Hope this helps :)
The high specific heat of water makes lakes to heat up more slowly than the air around it.
Water is said to have high specific heat, what this means is that it requires more energy to raise the temperature of water in relation to other substances.
Before water can become hot or warm, it first has to be able to absorb a lot of heat around. This is very important to climate and it also helps to determine if certain areas of the world are habitable.

What is the pH of a 0.15 M NH4OH solution with a Kb of 1.78 x 10^-5?
a. 11.21
b. 11.93
c. 12.09
d. 10.85
Answer:
The correct option is;
a. 11.21
Explanation:
The chemical equation for the reaction is;
NH₄OH ↔ NH₄⁺ + OH⁻
At the start of the reaction, we have;
NH₄OH ↔ NH₄⁺ + OH⁻
I [tex]{}[/tex] 0.15 0 0
C 0.15 - x +x +x
The [tex]k_b[/tex] = 1.78 × 10⁻⁵
Therefore, we have;
1.78 × 10⁻⁵ = [NH₄⁺][OH⁻]/NH₄OH = x²/(0.15 - x)
Which gives;
(0.15 - x) 1.78 × 10⁻⁵ = x²
x² + 1.78 × 10⁻⁵x - 2.67× 10⁻⁶ = 0
Factorizing the above equation online, gives;
(x + 0.00164294)(x - 0.00162514) = 0
Therefore;
x = -0.00164294, or x = 0.00162514
We use the positive result, which is x = 0.00162514 = 1.62514 × 10⁻³ = [OH⁻]
Therefore;
pOH = -log[OH⁻] = -log(0.00162514) = 2.789
pH + pOH = 14
Therefore;
pH = 14 - pOH = 14 - 2.789 ≈ 11.21089
The pH of a 0.15 M NH₄OH solution with [tex]k_b[/tex] = 1.78 × 10⁻⁵ = 11.21.
The pH of a 0.15 M NH₄OH solution with [tex]k_b[/tex] = 1.78 × 10⁻⁵ is approximately 11.21
pH value is the measure of acidic or base properties of a solution.
The answer to the given question is a. 11.21. It is explained as follows.
The range of pH value is between 0 to 14 in which value 7 is the neutral pH which is associate with water.
The water has no dominant properties of acid neither base.
The pH value below 7 is for acidic properties and for above 7 is associate with base properties.
The pH value of 0.15 M NH4OH solution is 11.21 as it displays strong base properties.
The correct answer is a. 11.21.
