The correct answer is B. The iris would get smaller, the pupil would get bigger.

Explanation

The iris is the name by which the colored part of the eye is known, it is located between the cornea and the lens. In the central part of the iris, there is a round opening known as the pupil. The relationship between these two parts of the eye is very important to sight because between them they control the amount of light that enters the eye. This occurs when the eye is exposed to a high amount of light, the iris muscles make the pupil smaller and the iris larger, limiting light entry into the eye. When the eye is exposed to low amounts of light or darkness, the iris becomes smaller and the pupil enlarges, allowing more light to enter. According to the above, the correct answer is B. the iris would get smaller, the pupil would get bigger. Because it describes the behavior of the iris and the pupil when going from a bright room to a dark room.

What variations do we see in forest types
Elza [17]

There are multiple different forest types on the planet, all of them with their own unique characteristics creating a certain forest ecosystem.

The tropical forests are evergreen, so are the boreal forests, but the temperate forests shade their leaves each autumn and grow them again in the spring. The tropical forests are fully active all year around, the boreal despite being green all the time are not active for big portion of the year, while the temperate forests are active from the end of the winter until mid autumn. The tropical forests create a lot of material for decomposition thus making the top part of the soil very fertile, the boreal forests do not create a lot of material for decomposition but instead very little which makes the soil relatively poor, and the temperate forests create a lot of material for decomposition especially in the autumn when they shed their leaves, thus contributing to very fertile top layer of the soil. The tropical forests have enormous biodiversity, the boreal forests are very monotonous and have very little biodiversity, while the temperate forests are kind of in between with medium level of biodiversity.

A proton gradient is an important part of both photosynthesis and cellular respiration.
Dennis_Churaev [7]

A proton gradient is an important part of both photosynthesis and cellular respiration because couple the favorable flow of H+ to transport specific metabolites into and out of organelles.

<h3>What is the proton gradient?</h3>

The gradient is sometimes called the proton-motive and can be thought of as a form of energy, force and force in a battery. Like other ions, protons are not able to cross directly through the phospholipid bilayer of the membrane, as the interior of the membrane is hydrophobic.

The proton gradient generated by this manipulation provided a driving force for ATP synthesis in the absence of light. This confirms the chemiosmotic theory, where a chemical potential across the membrane can provide energy for ATP synthesis.

The proton gradient produced by pumping protons during the electron transport chain is used to synthesize ATP.

masya89 [10]

Histrionic personality disorder is characterized by a widespread pattern of excessive emotionality and attention seeking. The diagnosis is by clinical criteria. Treatment is with psychodynamic psychotherapy.
