D. This is because artificial selection is basically the human breeding of plants or animals, and we do so in a way to bring forth the best traits to solve a problem or create a better product.
Hope this helps!
Small molecules are able to pass through a cell membrane because the membrane itself is semipermeable. Larger molecules require the cell expend energy to transport the molecules across the cell membrane, usually by engulfing them.
Answer: A
Explanation: the use of energy is a characteristic that distinguishes a fire from a flowering plant.
The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
Conifer Leaf.
Microphyll Leaf.
Megaphyll Leaf.
A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.
The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.
Composition is what it's made of vs texture being what the substance feels like.
