The given question is incomplete. The complete question is:
All of the flower mechanisms would help prevent pollination by a foreign species except __________.
A. A pollen tube grows in the style of its own species.
B. The stigma is sticky mainly to its own species of pollen.
C. The timing of flowering keeps pollinators moving among a limited number of species.
D. Flowers attract a small number of specialized pollinators, and therefore pollen is not spread equally to all available species of flowers.
E. Flowers of different species are the same color and attract similar pollinators.
Answer:
E. Flowers of different species are the same color and attract similar pollinators.
Explanation:
Plants of different species develop various morphological, physiological and behavioral strategies to ensure that the flowers of one species are not pollinated by pollens from any other species. One such structural adaptation is the production of flowers of a different color, size and shape.
These structural distinctions allow specific pollinators to visit the flowers of the particular species only. It ensures pollens from a different plant species do not land on the flowers of some other species. Production of flowers of the same color by different plant species would attract same pollinators and may result in pollination by a foreign species.
biosphere?
Answer:
The flow of matter and energy among Earth's geosphere, hydrosphere, atmosphere, and biosphere involves several processes. Some of these processes include:
1. The water cycle: Water evaporates from the hydrosphere into the atmosphere, forms clouds, and then precipitates back to the Earth's surface. This process helps in the transfer of water and energy between the hydrosphere and atmosphere.
2. Nutrient cycling: Nutrients like carbon, nitrogen, and phosphorus move through the biosphere through processes like photosynthesis, respiration, decomposition, and nutrient uptake by plants. These cycles help in the transfer of matter and energy between the biosphere and geosphere.
3. Energy transfer: Solar energy is absorbed by the Earth's surface, leading to heating of the geosphere. This heat is then transferred to the atmosphere through processes like conduction, convection, and radiation. The biosphere also relies on this energy for photosynthesis and other metabolic processes.
4. Geological processes: The geosphere plays a role in the cycling of matter and energy through processes like weathering, erosion, and volcanic activity. These processes can release or store nutrients and gases, affecting the hydrosphere, atmosphere, and biosphere.
These are just a few examples of the interconnected processes that contribute to the flow of matter and energy among Earth's geosphere, hydrosphere, atmosphere, and biosphere.
Answer:
Explanation:
Meiosis is a type of cell division in which the ploidy of the organism reduces to half in the daughter cells.
Meiosis produces 4 daughter cells from 1 parent cell with a different combination of the genetic material but haploid chromosomes.
The meiosis process takes place in two stages in which during the first stage, the homologous chromosomes separate reducing the chromosome number to half that is from diploid chromosomes of parents to haploid in daughter.
Since the process of meiosis form haploid gametes in both male and female therefore after fertilization restores the diploid chromosomes of the parent cell and form a diploid structure.
