A girl has her eyes shut and is standing inside a brightly lit room. What happens to her pupils when she opens her eyes? Why?
Answer:
When you open yours eyes in a brightly lighted area to a dark room (such as a cinema hall), you experience difficulty in seeing objects for a short while slowly, your vision is improved. This improvement is called dark adaptation. This change is due to (a) regeneration of the visual purple (or rhodopsin), the pigment of the rods, which was earlier broken down due to bright light, and (b) dilation of the pupil permitting more light to enter the eyes.
The pupil will constrict. Bright light will contract the muscles of the iris.
What is structure of an eye?An eye is a spherical structure responsible for vision.
An eye consists of three main layers:
Outer layer: It consists of cornea and sclera. Cornea extends into a membrane like structure called conjunctiva.Middle layer: This layer contains iris, ciliary body and choroid.Inner layer: Consists of retina where an inverted image of the object is formed. The optic nerve carries the visual information to brain.Two fluids namely aqueous humour and vitreous humour are present which maintain the shape of an eye.
The coloured part of an eye is called iris. It regulates the intensity of the light entering to the eye by controlling the diameter of a pupil (small aperture in the iris).
The lens of an eye is biconvex. It directs the light to the retina.
Therefore, eye is a crucial sensory organ.

compare the circulatory system of a plant and animal
plz help do not copy off anything because this is a unit test
Answer:
The circulatory system is the method of transport in plants and animals. Animals must have nutrients and oxygen reach every cell in their body. Plants must have nutrients and carbon dioxide reach every cell in their “body.” Both plants and animals must also have waste products removed from their systems.
Explanation:
You are gonna have to change the wording a little but thats ok! An y'know what? I have the same answer on one of my past test we did like a week ago!
Answer:
In plants, there is a conducting tissue that is located in the veins. Inside, there are xylem cells that conduct water and minerals upward from roots to leaves and phloem that conducts food. Plants have only water solutions flowing through the tubing. Animals can have one of two kinds of circulatory systems: open or closed. In animals, each blood vessel in the network is responsible for transporting nutrients and oxygen to cells and for removing wastes and carbon dioxide from cells.

○The temperature fell overnight, and colder air can hold less water vapor.
Hope this helped you- have a good day bro cya)
Dew form in the morning because the temperature fell overnight, and colder air can hold less water vapor. The correct option is c.
What is dew?As the temperature drops and things get colder, dew forms. The air around an object will cool if it becomes cold enough. Warm air can store more water vapor than cold air, but not as much. As a result, the air around cooling objects is forced to condense water vapor.
At the night, the temperature is less because of not sun. In less temperature, water freezes, and the air consensus turns into drops of water.
Water tends to gather on surfaces and draw itself together as droplets, or dew, since it has high surface tension. It frequently gathers in locations that are naturally chilly.
Therefore, the correct option is c, The temperature fell overnight, and colder air can hold less water vapor.
