Answer: The correct statements are 1 and 2:
1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.
2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Explanation:
Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
1. Sensory Input Sensory receptors gather information about the internal and external environments and convert it to a form which can be used by the animal. This information is then conveyed to integration centers.
2. Integration The input is interpreted and associated with the bodies appropriate response. Integration is carried out in the Central Nervous System (CNS).
3. Motor Input Conduction of signals from the integration centers (CNS) to effecter cells.
No body going to understand the response if you don't have whats its about on here but a little tip is you can go and into a few key sentences and highlight the main words to help you under stand the question or response better.
Hope I helped
