Her pupils shrink because the muscles contract.

When the girl opens her eyes in a brightly lit room, the muscles in her iris contract, causing the pupils to constrict or shrink. This is a reflex response to protect the eyes from excessive light by reducing the amount of light entering the eye.
Answered by GPT 3.5
The part of the eye that uses muscle tissue for opening and closing movements is the iris. The iris contains smooth muscle fibers that control the size of the pupil, allowing it to dilate or constrict in response to different lighting conditions.

The example that shows an organism that cannot reach homeostasis through internal changes is "A lizard is cold, and it moves to a sunny rock to warm up." In this case, the lizard is relying on an external stimulus (the sun) to regulate its body temperature, rather than internal mechanisms.

Homeostasis is achieved through cells maintaining internal stability.

The correct statement is: "Both make it possible for you to respond to your environment by moving."

Both muscle cells and bone cells contribute to the body's ability to move. Muscle cells, specifically skeletal muscle cells, contract and relax to produce movement, while bone cells provide structural support and protection, allowing the muscles to attach and exert force for movement.

The function of an organ system is "to work together to do a specific job."

Organ systems in the human body are composed of different organs working together to perform specific functions that are necessary for survival and overall body function. Each organ system has a specific role or job, and together they collaborate to maintain homeostasis and carry out vital processes such as respiration, digestion, circulation, and movement.

To find out how much money Jaden will earn for 4 lawn-mowing jobs (l) and 6 pulling-weeds jobs (w), we can substitute the given values into the expression 25l + 20w.

So, substituting l=4 and w=6:

25(4) + 20(6)

Calculating this expression:

= 100 + 120

= 220

Therefore, Jaden will earn $220 for 4 lawn-mowing jobs and 6 pulling-weeds jobs.

To find the surface area of a cube with a side length of 10 cm, we can substitute the value of s=10 into the formula 6s^2.

So, substituting s=10:

6(10)^2

Calculating this expression:

= 6(100)

= 600

Therefore, the surface area of a cube with a side length of 10 cm is 600 square centimeters (cm^2).

To find out how much Alicia will earn for a job that takes 3 hours (h), we can substitute the given value into the expression 65h + 100.

So, substituting h=3:

Calculating this expression:

= 195 + 100

= 295

Therefore, Alicia will earn $295 for a job that takes 3 hours.

To find the number of feet the cliff-diver is above the ocean in 2 seconds (t), we can substitute the given value into the formula 75 - 16t^2.

So, substituting t=2:

75 - 16(2)^2

Calculating this expression:

= 75 - 16(4)

= 75 - 64

= 11

Therefore, the cliff-diver is 11 feet above the ocean in 2 seconds.

To find the cost for a garden that has a length (l) of 4 yards and a width (w) of 3 yards, we can substitute the given values into the expression 1.50(2l + 2w).

So, substituting l=4 and w=3:

1.50(2(4) + 2(3))

Calculating this expression:

= 1.50(8 + 6)

= 1.50(14)

= 21

Therefore, the cost for a garden with a length of 4 yards and a width of 3 yards would be $21.

To find out how much it will cost Mr. Imani to purchase 10 packs of paper (p) and 30 notebooks (n), we can substitute the given values into the expression 1.25p + 2.50n.

So, substituting p=10 and n=30:

1.25(10) + 2.50(30)

Calculating this expression:

= 12.50 + 75

= 87.50

Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.

To find out how much space Robert will have left for his presentation, we need to subtract the total area of the 10 squares (10s^2) from the total area of the poster board (720 square inches).

Given that s (the side length of the squares) is 7 inches, we can substitute s=7 into the expression 720 - 10s^2.

So, substituting s=7:

720 - 10(7^2)

Calculating this expression:

720 - 10(49)

720 - 490

= 230

Therefore, Robert will have 230 square inches of space left for his presentation if he uses squares with 7-inch sides.

To find the cost for a garden that has a length (l) of 5 yards and a width (w) of 2 yards, we can substitute the given values into the expression 7(l + 2w).

So, substituting l = 5 and w = 2:

7(5 + 2(2))

Calculating this expression:

= 7(5 + 4)

= 7(9)

= 63

Therefore, the cost for a garden with a length of 5 yards and a width of 2 yards would be $63.

The statement that best describes a command economy is: "The government controls most economic activity."

In a command economy, the government has the power to make decisions and control economic activities such as production, distribution, and pricing. The government sets goals and makes decisions on what goods and services will be produced and how they will be allocated. Individual choices and market forces have limited influence in a command economy compared to government directives and planning.
