Answer:
Evergreens are plants that maintain their leaves in all seasons and include trees such as pine, cedar, and mango. 2. Deciduous trees lose their leaves seasonally and include trees such as elm and maple. 3. Hardwoods reproduce using flowers and have broad leaves: hardwoods include trees such as maple, elm, and mango. 4. Conifer leaves are generally thin and needle-like, while seeds are contained in cones. Conifers include pine and cedar.
Explanation:
- Evergreens plants: These plants keep the foliage the year. They change leaves during their whole life, but the frequency in which they change them is not the same as the deciduous plants, and this event does not coincide with any season in particular. They do not need to lose leaves during unfavorable seasons. These species develop different strategies and adaptations to go through unfavorable weather conditions. They have special leaves to avoid water loss or freezing, some of them are thin and needle-like shaped, or might be covered with wax or fuzz. Example: Pine, cedar.
- Deciduous plants: During autumn and winter, deciduous trees from temperate forests need to store different nutrients that will be used for the plant growth during the following spring. Storaging nutrients in leaves require too much energy and constant photosynthetic activity, which might be very difficult for the plant to support during these colder seasons. To confront this situation, these species have developed some strategies such as leaves senescence. The tree stops supplying water and nutrients to the leaves, so these last ones stop producing chlorophyll. When this molecule is completely lost, other pigments that were masked by chlorophyll, show up. Before senescence occurs, pigments such as carotenoid, anthocyanin, or pheophytin reveal yellow, orange, red, purple, and brown tones, which are the characteristic autumn colors. Example: maple and elm
- Angiosperm characterize for their reproductive strategy, producing flowers and fruits, and dispersing by their seeds. These last ones are located in an ovary (in the fruit). These species attract pollinizers through the flower characteristics and reward and attract animals with their fruits, guaranteeing seeds dispersion. Example: maple and mango
- Gymnosperm does not develop flowers nor fruits. They have naked seeds on the surface of scams or leaves. Seeds frequently develop in pine cones, which are specialized branches. Example: Pine, cedar
- Conifer belongs to the Gymnosperm.
Answer:
Phytoplankton are the autotrophic components of the plankton community and a key part of ocean and freshwater ecosystems.
Answer:
Explanation: The two finches eat different kinds of food. The woodpecker finch eats insects and the large ground finch eats seeds. They do not compete for the same resources.
Answer:
completely by greenhouse gas emission from human activities
The answer is no, fibrocartilage cannot provide articular surface as smooth as the original hyaline cartilage.
This is because these two cartilages are different in composition (structure) and thus provide slightly different function.
Fibrocartilage is stiff and contains many collagen fibers type I and II, while hyaline cartilage is a soft cartilage that contains collage fibers type I. Fibrocartilage contains only few chondrocytes in lacunae, while hyaline cartilage has large number of them. As a result, fibrocartilage provide a restricted mobility, while hyaline cartilage enables smooth movements.
