Answer:
Following are the six accurate statements:
1. The seeds allow the plant embryos to get dispersed over the long distances from the parent plant through animals or wind.
2. In various angiosperms, the male gametophyte comprised in a pollen grain can get translocated various miles away through animal or wind.
3. Fruits help in the dispersal of seeds by animals or wind, which eat or carry the fruits.
4. The fruits protect the seeds, and the seeds nourish and protect the plant embryos.
5. The floral components of the sporophyte safeguard the reduced female gametophyte from dying out and from ultraviolet radiation.
6. Flowers fascinate animal pollinators carrying pollen from other plants of the similar species.
The other mentioned statements are incorrect. The spores are not generated in the angiosperms, however, seed gets produced post-fertilization that comprises developing embryo. The cotyledons exhibit stored food substance and seeds are comprised within the seeds. The seeds get dispersed with the help of abiotic and biotic agents.
The fertilization in angiosperms is not reliant upon the water, it is rather the pteridophytes and bryophytes that cannot complete their life cycle in the absence of water. In angiosperms, the main plant body is sporophyte that safeguards the female gametophyte.
Plants are made from Meiosis no matter what
The answer would be A, as the dominant genes always have a capital to represent them whereas the recessive gene is represented by a lower case hope this helps.

A flea and dog are an example of parasitism, because the flea irritates the dog's skin and feeds on its blood.
In a parasitic interaction, one organism benefits whereby the other one harmed. It is a positive - negative relationship. This interaction involves the interaction between the host and the parasite. The host is the bigger organism, here, the dog that is being harmed. The parasite is the flea causing the harm and benefiting from the relationship.
Certain bacteria live in the digestive tract of humans, and their relationship is an example of because mutualism the bacteria help humans to break down the food they eat.
In mutualism, the interaction is based on both organism deriving benefit from one another. Here, the bacteria gets its nourishment by breaking down human food. Human beings are able to digest the food better and are also nourished. A win-win situation is established.
Cattle egrets eat insects off the back of an elephant, which is an example of commensalism because the cattle egrets benefit without either harming or helping the elephants.
This relationship is known as commensalism in which one organism derives benefit. The other one derives no benefit and it is also not harmed in the process. The egrets feeds on the insects that are not harming the cattle.
