A significant factor in the exponential population growth over the past two centuries is; good sanitation and medical advances.

In exponential growth, the rate of the growth in population usually increases over time and this is usually directly proportional to the size of the population.

Now, this rate discussed above usually causes the population to increase much more faster.

We can say that good sanitation and medical advances will contribute to the exponential growth of the human population due to the fact that when an environment is clean, it will prevent the accumulation of dirt and infectious particles to accumulate inside the body which means less contraction of deadly diseases.

Secondly, medical advances have helped in curing of deadly diseases that cause more deaths and this means the death rate will decrease and population will increase.

Answer and Explanation: As a result of mitosis, each of the two new cells produced from the original cell during cytokinesis have the same chromosomal constitution as the parental nucleus. Cytokinesis is the actual division of the cytoplasm that results in two daughter cells that are diploid. Mitosis is a type of division that occurs during growth in somatic cells through replication of chromosomes and their subsequent redistribution.

Answer:

C. 12 units.

Right on edge

In the diagram, ce=12 units and be=5 units. Based on the given information. So, the answer will be 7 units. Thus, option B is correct.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In the diagram,

⇒ CE = 12 units

⇒ BE = 5 units

Now,

Since, Triangle CBE is an right triangle.

And, We have;

⇒ CB = AB

⇒ ∠DBC = 90°

⇒ ∠ABE  = ∠DBC = 90° (opposite angles formed by the intersection of  AC and DE.)

As, ∠CBE and  ∠ABE are supplementary angles and form a straight line.

So, We get;

⇒ ∠CBE + ∠ABE =180°

⇒∠CBE =  180° - ∠ABE  

           = 180°- 90°

           = 90°

And, Between triangle ΔCBE  & ΔABE;

⇒ ∠CBE = ∠ABE = 90°

⇒ CB = AB (given)

⇒ BE = BE  (common side)

Hence, The triangles Δ CBE  & ΔABE are congruent.

⇒ Δ CBE  ≅ ΔABE( by S-A-S Congruency)

⇒ CE = AE ( as triangle Δ CBE  & ΔABE are congruent then the sides are same.)

⇒  AE = 12 units

Thus, The length of AE = 12 units

Hope it helps!

Answer:

x⁴ - 6x³ + 7x² + 6x - 8

Explanation:

Write the linear factor for each zero.

[tex]g(x) = (x - 1) (x + 1) (x - 2) (x - 4)[/tex]

Multiply the first two, then the second two.

[tex]g(x) = (x^{2} + x - x -1) = (x^{2} - 1) then (x^{2} - 4x - 2x + 8)[/tex]

Use the Distributive Property.

[tex](x^{2} - 1) (x^{2} - 6x + 8) = (x^{4} - 6x^3 + 8x^{2} - x^{2} + 6x - 8)[/tex]

Simplify.

Answer:

Explanation:

By definition, the minimum mass of hydrogen gas required to produce 226 kJ of heat is 1.8697 grams.

The reaction is as follows:

2 H₂(g) + O₂(g) → 2 H₂O(g)     ΔH = - 483.5 kJ

In this reaction, you can see that 2 moles of H₂ produces 483.5 kJ of heat. But you want to release 226 kJ of heat.

So you can apply the following rule of three: if 483.5 kJ is released by 2 moles of H₂, 226 kJ of heat is released by when moles of H₂?

[tex]amount of moles of H_{2} =\frac{226 kJx2 moles }{483.5 kJ}[/tex]

amount of moles of H₂= 0.93485 moles

Molar mass is the amount of mass that a substance contains in one mole. In this case, the molar mass of H₂ is 2 [tex]\frac{g}{mole}[/tex].

So, the mass containing 0.93485 moles is calculated as:

0.93485 moles× 2 [tex]\frac{g}{mole}[/tex]= 1.8697 grams

Finally, the minimum mass of hydrogen gas required to produce 226 kJ of heat is 1.8697 grams.
