Answer:

a. Gluteus maximus

Explanation:

The gluteus maximus muscle is one of the three gluteal muscles. As the name reflects, the gluteus maximus is one of the biggest muscle in the body. It is also heaviest muscle among the three gluteal muscles. The gluteus maximus is a superficial muscle of buttocks. Functionally, it serves as extensor muscle for femur bone of thighs.

How does reduction of air pressure affect evaporation of water?

san4es73 [151]

Air also affects evaporation,If a air pressure is high on the surface of a body of water,then the water will not evaporate easily.The pressure pushing down on the water makes its difficult for water to escape into the atmosphere as vapor... Temperature,of course,affects how quickly evaporation happens.

_____________contents empty into the small intestine and must quickly be neutralized to prevent damage to the intestinal wall. U

Sonbull [250]

Answer:

Pancreatic juice, NaHCO₃.

Explanation:

The buffers are the chemical solution which neutralizes the acidic effect and the human body also produces the biological buffers which help maintain the pH.

The pancreatic juice secreted by the pancreas gets drained into the duodenum of the small intestine and neutralizes the effect of the acidic content in the stomach bolus. The pancreatic juice contains the sodium bicarbonate which neutralises the effect of the HCl.

Thus, Pancreatic juice, NaHCO₃ is the correct answer.

What structures work in antagonistic pairs to move bones?

Olegator [25]

Answer

Option C - Skeletal Muscles

Explanation

Antagonistic pairs are the muscles that are functionally opposite, if one produces flexion, then the other's primary action is an extension. Skeletal muscles work in pairs to move a bone so that the muscles can function properly. They contract the bone making nerves deliver a message to the brain. For example. Biceps and triceps. The lower arm is moved upwards when the biceps muscle contracts and the triceps muscle is relaxed and vice versa.

The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released as ELECTRONS move through the first electron transfer chain. This energy pumps HYDROGEN IONS into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

----------------------------------------------------------------------------------------------------

Luminous energy is trapped by chlorophyll in Photosystem II.
When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
<em>When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. </em>
Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
<em>When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II. </em>
When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
The released energy is used to produce ATP molecules.
Hydrogen ions go back from the stroma to the thylakoid compartment.

The final products are oxygen, ATP, and NADPH.
