Which of the following best pairs the leaf structure with its role?

a. stomata–absorbs light
b. veins–connect the vascular tissue to the stem
c. palisade mesophyll–coats the epidermis to prevent water loss
d. cuticle–conducts photosynthesis

B. Veins–connect the vascular tissue to the stem

Explanation:

A.- Wrong. The stomata's function is transpiration. They serve as receiving and releasing port for oxygen, and carbon dioxide.

B.- Veins. Incorrect, the veins are the organ in charge of connecting the vascular tissue that gathers and distributes water and food through the vascular net in the leaf.

C.- Incorrect, they capture light to propitiate photosynthesis.

D.- Cuticule's function is to prevent the escape of water on the epidermal plant's surface, as well as preventing the barrier for other molecules.

The reason behind B to be the best option is that the middle leaf vein connects the leaf to the stem.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
