Sodium carbonate is a basic salt because it is a salt derived from a weak acid and strong base.
Answer:
D. contact metamorphism
Explanation:
When there's a volcanic activity in certain area, very often it happens that there's magma that intrudes into the cold rock in the surrounding area. The intrusion of the hot magma into the cold rock layers causes big changes into the structure of the rocks. The high temperature and high pressure manage to influence the structure of the preexisting rocks, mostly on the places where the magma touches the cold rocks, leading to the formation of metamorphic rocks. This type of metamorphism is known as contact metamorphism.
They both have a bilipid cell membrane. This means that their cell membrane is composed of phospholipids. Both cells also have ribosomes. This is a critical cell organelle that is involved in the translation of mRNA to proteins. Their genetic material is also made up of deoxyribose sugars (DNA).
Answer:
Passes absorbed energy to chlorophyll A.
Explanation:
Chlorophyll is a pigment found on the chloroplasts, it absorbs and reflects light's fotons in order to fuel the photosynthesis process where plants convert light into energy. There are two types of chlorophill:
- <em>Chlorophyll A:</em> a blue/green substance that is always necessary for photosyntesys, it absorbs light from red to blue areas and it acts as a primary electron donor in the electron transport chain.
- <em>Chlorophyll B: </em>a yellow/green substance that absorbs only blue light, it serves as an extension for the plant to absorb a broader range of light. <em>The extra energy absorbed by this clorophyll is then tranfered to chlorophyll A</em>.
