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.

Answer:

a biome is a community with distinct climates for organisms both plant and animals.

Explanation:

When a biome is destroyed, food sources for many organisms are lost, as well as their habitat. many species will become endangered or extinct. as ome species become extinct it causes a chain reactiom affect many other species to become endangered and the nature will fail to balance. losing a biome causes loss of many plantatioms which many lead to more CO2 in the atmosphere and hence global warming. global warming casue draught, famine and again, loss of many species and even spread of diseases.

Answer:

The dependent variable is the variable that changes when the independnet variable is manipulated.

Explanation:

The independent variable is the water temperatures, the variable you change. The dependent variable is the rate of the water freezing.

Answer:

True

Explanation:

In an experiment, if you change more than one variable at a time, you will not know what is causing the potentially different outcome. If you only change one variable and leave all other factors constant, you will know exactly what is causing the data.

Explanation:

Independent Variable Tap water, salt water.

Dependent Variable rate of evaporation.

Hypothesis Tap water will evaporate faster than salt water.

A variable is anything we measure: an event, a time interval, etc. It does not have a fixed value.

It is a variable whose value is not affected by the other variables being studied. Alternatively, it is the cause.

It is a variable whose value  is determined by the changes in the independent variable. It is the effect.

A hypothesis is a statement that is presented as an argument and then is tested to see if it is correct.

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.

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.

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.

The answer is Precipitation

Explanation:

Answer:

it is a source of Precipitation

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.
