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.

True or False: In an experiment to avoid errors you should only change one variable, all other factors should remain the same.
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.

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.

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.

Answer:
The correct answer is - fatty acid.
Explanation:
A phospholipid is a one of lipid molecule which is present as major component of cell membrane, that plays a significant role. Phospholipids allow for selective passage of ions and other molecules through the cell membrane.
Phospholipid is structurally similar to triglyceride except that it is made up of two fatty acids instead of three fatty acid, in phosphoplipid third fatty acid is replace wit a phosphate group, however, glycerol molecule present in both. The phosphate group of the phospholipid is negatively-charged which makes it polar or hydrophilic head, .
Thus, the correct answer is - fatty acid.

What is the term for the interior posterior surface of the eyeball that includes the retina, optic disc, macula and posterior pole that can be seen with an ophthalmoscope
Answer:
Fundus.
Explanation:
The fundus or ophthalmoscopy consists of viewing the retina and the optic disc through the pupil and the transparent media of the eyeball (cornea, aqueous humor, crystalline humor, and vitreous humor) including the optic disc, retinal vessels, macular area and fundus as a whole. It is an important component of the clinical evaluation of many diseases and is the only location where the vascular bed can be observed in vivo in a bloodless manner. The direct ophthalmoscope is available to perform it in Primary Care (PC) consultations and in other specialties, this is an optical instrument that directs light directly onto the retina through a mirror that reflects a ray from the light source. This mirror has a central hole that allows the observer to view the illuminated retina. The major retinal vessels are examined and tracked distally as far as possible in each of the four quadrants (superior, inferior, temporal, and nasal). The color, tortuosity, and caliber of the vessels are examined. The posterior pole is between the temporal vascular arches, measures 5-6 mm, and is where most of the lesions in diabetic retinopathy are located, such as microaneurysms, hemorrhages or exudates.
