The correct answer is: C) the extraction of energy from high-energy electrons remaining from glycolysis and the citric acid cycle

Electrons from electron carriers (NADH and FADH from glycolysis and citric acid cycle) donate electrons to the electron transport chain and that causes changes in protein complexes of electron transport chain. As a consequence, protein complexes pump H+ across a selectively permeable cell membrane from the mitochondrial matrix into the intermembrane space of mitochondria.  H+ can only get back and pass through the inner mitochondrial membrane with the help of ATP synthase (down their electrochemical gradient). ATP synthase turned by the force of the H+ diffusing through it forms ATP by adding a phosphate to ADP. This type of ATP synthesis  is called oxidative phosphorylation and it is based on chemiosmosis-movement of ions across a selectively permeable membrane.

Answer:

253.585 square inches

Explanation:

The figure can be decomposed into 2 rectangles and a quarter circle.

Area of the figure = area of rectangle 1 + area of rectangle 2 + area of ¼(circle)

✔️Area of rectangle 1 = Length × width

Length = 10 in

Width = 6 in

Area of rectangle 1 = 10*6 = 60 in²

✔️Area of rectangle 2 = Length × width

Length = 10 in

Width = 6 + 7 = 13 in

Area of rectangle 2 = 10*13 = 130 in²

✔️Area of ¼(circle) = ¼(πr²)

r = 9 in

π = 3.14

Area of ¼(circle) = ¼(3.14*9²) = 63.585 in²

✅Area of the figure = 60 + 130 + 63.585 = 253.585 square inches

PLEASE HELP!! Identify a specific environmental factor that will cause a response to living things, and describe how this factor
jasenka [17]

Answer:

A specific environmental factor that will cause a response to living things will be light from the sun.

Explanation:

An enhanced amount of light from Sun will cause the plants to have enhanced photosynthesis. Photosynthesis can be described as a process by which plants use light energy from the sun to convert carbon dioxide and water into sugar (food) and oxygen.

In animals, enhanced amount of light from the sun will cause sweating and vasodilation.

The process of photosynthesis won't occur in animals and the process of sweating won't occur in plants.
