Only one acidic because litmus turns blue in bases :D
The answer is B, use energy they take in from the environment to convert inorganic molecules into complex organic molecules.
Answer:
Determine if the limiting factors listed below are density-dependent or density-independent?
food is density-dependent
Number of mates is also density-dependent
Habitat is density-dependent
a hurricane is density-independent
Hunting by humans is density-independent
Industrial pollution is density-dependent
Explanation:
The above limiting factors shows some density-dependent while one is density-independent. Food, habitat, and industrial pollution all depends on population as the lesser the population the smaller the limiting factors caused while hurricane and hunting by humans are density-independent.
Food, Habitat, Number of mates, and industrial pollution are all limiting factors that solely depends on density as the increase in density affects it greatly while hurricane and hunting by humans has nothing to do with increase or decrease in density, hence, they are density-independent
The GI tract consists of mouth, esophagus, stomach, small intestine, large intestine, and anus,
<h2>Pathway of digestion</h2>
The GI tract is a series of hollow organs that is joined in a long, twisting tube from mouth to the anus. The GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus are the hollow organs while on the other hand, the liver, pancreas, and gallbladder are the solid organs of the digestive system.
The food enters through mouth which moves after chewing to esophagus then to the stomach. After digestion, all the nutrients are absorbed whereas waste materials are send to the small and then large intestine and finally to anus.

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.
