B.
Oxygen enters the bloodstream directly from the nose.
C.
Oxygen is transferred to the bloodstream as blood passes by the lungs.
D.
The heart pumps air into the blood through the lungs.
Answers
Option C is the best description of how the human circulatory and respiratory systems interact, as it accurately reflects the process by which oxygen is transferred to the bloodstream as blood passes by the lungs.
How do the human circulatory and respiratory systems interact?The circulatory and respiratory systems work together to ensure that oxygen is delivered to the body's cells and carbon dioxide is removed. The respiratory system is responsible for taking in oxygen and expelling carbon dioxide, while the circulatory system is responsible for transporting oxygen and nutrients to the body's cells and removing waste products.
During respiration, oxygen is taken in through the nose and mouth and travels down the trachea, or windpipe, and into the lungs. In the lungs, oxygen is transferred to the bloodstream through tiny blood vessels called capillaries. At the same time, carbon dioxide is removed from the bloodstream and expelled through the lungs during exhalation.
The heart plays a crucial role in the circulatory system by pumping blood through the body, including through the lungs. As blood flows through the lungs, it picks up oxygen and releases carbon dioxide, which is then transported to the heart and pumped out to the rest of the body.
Therefore, oxygen is transferred to the bloodstream as blood passes by the lungs.

Answer:
2x = 6
Step-by-step explanation:
Simplify the following algebraic expressions.
- 6x + 5 + 12x -6
2(x - 9) + 6(-x + 2) + 4x
3x2 + 12 + 9x - 20 + 6x2 - x
(x + 2)(x + 4) + (x + 5)(-x - 1)
1.2(x - 9) - 2.3(x + 4)
(x2y)(xy2)
(-x2y2)(xy2)
Solution
Group like terms and simplify.
- 6x + 5 + 12x -6 = (- 6x + 12x) + (5 - 6)
= 6x - 1
Expand brackets.
2(x - 9) + 6(-x + 2) + 4x = 2x - 18 - 6x + 12 + 4x
Group like terms and simplify.
= (2x - 6x + 4x) + (- 18 + 12) = - 6
Group like terms and simplify.
3x2 + 12 + 9x - 20 + 6x2 - x
= (3x2 + 6x2) + (9x - x) + (12 - 20)
= 9x2 + 8x - 8
Expand brackets.
(x + 2)(x + 4) + (x + 5)(- x - 1)
= x2 + 4x + 2x + 8 - x2 - x - 5x - 5
Group like terms.
= (x2 - x2) + (4x + 2x - x - 5x) + (8 - 5)
= 3
Expand and group.
1.2(x - 9) - 2.3(x + 4)
= 1.2x - 10.8 - 2.3x - 9.2
= -1.1x - 20
Rewrite as follows.
(x2y)(xy2) = (x2 x)(y y2)
Use rules of exponential.
= x3 y3
Rewrite expression as follows.
(-x2y2)(xy2) = -(x2 x)( y2 y2)
Use rules of exponential.
= - x3 y4
Simplify the expressions.
(a b2)(a3 b) / (a2 b3)
(21 x5) / (3 x4)
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
(4x - 12) / 4
(-5x - 10) / (x + 2)
(x2 - 4x - 12) / (x2 - 2 x - 24)
Solution
Use rules of exponential to simplify the numerator first.
(a b2)(a3 b) / (a2 b3) = (a4 b3) / (a2 b3)
Rewrite as follows.
(a4 / a2) (b3 / b3)
Use rule of quotient of exponentials to simplify.
= a2
Rewrite as follows.
(21 x5) / (3 x4) = (21 / 3)(x5 / x4)
Simplify.
= 7 x
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
Multiply terms in numerator and denominator and simplify.
(6 x4)(4 y2) / [ (3 x2)(16 y) ] = (24 x4 y2) / (48 x2 y)
Rewrite as follows.
= (24 / 48)(x4 / x2)(y2 / y)
Simplify.
= (1 / 2) x2 y
Factor 4 out in the numerator.
(4x - 12) / 4 = 4(x - 3) / 4
Simplify.
= x - 3
Factor -5 out in the numerator.
(-5x - 10) / (x + 2) = - 5 (x + 2) / (x + 2)
Simplify.
= - 5
Factor numerator and denominator as follows.
(x2 - 4x - 12) / (x2 - 2x - 24) = [(x - 6)(x + 2)] / [(x - 6)(x + 4)]
Simplify.
= (x + 2) / (x + 4) , for all x not equal to 6

Inequality shows a relationship between two numbers or two expressions.
The equivalent inequality of [tex]\frac{k}{-2}[/tex] ≤ 4 is k ≤ -8.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
Example:
2 < 4
2x < 10
3x > 18
We have,
[tex]\frac{k}{-2}[/tex] ≤ 4
We will make an inequality in terms of k on one side.
Multiply -2 on both sides.
k ≤ -2 x 4
k ≤ -8
Thus,
The equivalent inequality of [tex]\frac{k}{-2}[/tex] ≤ 4 is k ≤ -8.
