Answer:
38. Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
39. The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas
40. Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
41. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

When ice forms, one water molecule's hydrogen atoms form weak hydrogen bonds with the tops of the oxygen atoms of two other water molecules. Lining up the water molecules in this pattern takes up more space than randomly arranging them.
<h3>What is polarity?</h3>
A physical property of compounds that connects other physical properties like melting and boiling points, solubility, and intermolecular interactions between molecules is referred to as polarity.
When ice forms, one water molecule's hydrogen atoms form weak hydrogen bonds with the tops of the oxygen atoms of two other water molecules.
Lining up the water molecules in this pattern takes up more space than randomly arranging them.
When water freezes, the water molecules slow down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern, with molecules further apart than when the water was liquid.
Thus, because of this frozen water take on the pattern it does.

Arbitrary level refers to the fundamental vertical subdivision of an excavation square, implied only when easily identifiable natural strata are absent and when natural strata are more than ten centimeters thick.
Natural strata refer to a vertical subdivision of an excavation square, which is reliant on the natural breaks in the sediments in terms of grain size, color, hardness, texture, or other features.
It is important to know the difference between the arbitrary and natural levels as arbitrary levels could amalgamate artifacts from distinct natural levels, that is, of distinct geologic contexts.
The archaeologists can recover the smallest ecofacts and artifacts with the assistance of flotation, screening, and bulk matrix processing
