Double fertilization occurs in Angiosperms
Answer:
The longer answer lies in the details of photosynthesis, the electromagnetic spectrum, energy and “special pairs” of chlorophyll molecules in each plant cell. ... As such, plants look green because they absorb red light most efficiently and the green light is reflected.
Explanation:
Green plants are green because they contain a pigment called chlorophyll. Chlorophyll absorbs certain wavelengths of light within the visible light spectrum. ... Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants
If they are decreased at the same time and the same amount is being taken away from them at the same time then the gravitational force would stay the same but if they are be decreased one then the other they will go back and forth
Answer:
the average percentage of energy lost as heat
Explanation:
An energy pyramid (also called trophic pyramid) is a graphical representation that exhibits how energy flows at each trophic level in a particular ecosystem. In an energy pyramid, it is possible to determine how much energy is available at each trophic level and how energy flows from producers (e.g., photosynthetic plants) to primary consumers (e.g., herbivores), then from primary consumers to the next trophic level (e.g., carnivores), and so successively to all major trophic groups (e.g., higher carnivores). During this chain, energy is lost as heat when it is transferred to the next level, and the average percentage of energy lost increases at each trophic level, thereby less and less energy is available to major trophic groups.
The 4 divisions of Gymnos:
1- coniferophyte
2- Cycadophyta
3- Ginkgophyta
4- Gnetophyta
Describe
1- Conifers : Pines , firs , redwoods
2- Coniferophyta : seeds , large
3- Cycadophyta : Tropical and subtropical
4- Ginkgophyta : Only living Meso Era survived in China .
