Answer the following question given this paragraph: Algae are like plants mainly because they contain chloroplasts. This allows them to make food by photosynthesis. Algae are important producers in water-based ecosystems such as the ocean. On the other hand, algae lack other plant structures. For example, they don't have roots, stems, or leaves. Also unlike plants, some algae can move. They may move with pseudopods or flagella. Q: Algae are like plants mainly because they contain what? Choices: - organelles - cells - cell wall - chloroplasts A:
chloroplasts

Answer the following question given this paragraph: Community Ecology A biological community consists of the different species within an area, typically a three-dimensional space, and the interactions within and among these species. Community ecologists are interested in the processes driving these interactions and their consequences. Questions about conspecific interactions often focus on competition among members of the same species for a limited resource. Ecologists also study interactions among various species; members of different species are called heterospecifics. Examples of heterospecific interactions include predation, parasitism, herbivory, competition, and pollination. These interactions can have regulating effects on population sizes and can impact ecological and evolutionary processes affecting diversity. For example, Karner blue butterfly larvae form mutualistic relationships with ants. Mutualism is a form of a longterm relationship that has coevolved between two species and from which each species benefits. For mutualism to exist between individual organisms, each species must receive some benefit from the other as a consequence of the relationship. Researchers have shown that there is an increase in the probability of survival when Karner blue butterfly larvae (caterpillars) are tended by ants. This might be because the larvae spend less time in each life stage when tended by ants, which provides an advantage for the larvae. Meanwhile, the Karner blue butterfly larvae secrete a carbohydraterich substance that is an important energy source for the ants. Both the Karner blue larvae and the ants benefit from their interaction. Q: What consists of the different species within an area? Choices: - abundant community - science community - contamination community - biological community A:
(Answer)
biological community
Ques: Answer the following question given this paragraph: An ovule is a female reproductive structure in seed plants. It contains a tiny female gametophyte. The gametophyte produces an egg cell. After the egg is fertilized by sperm, the ovule develops into a seed. Q: What does the ovule develop into after fertilization? Choices: - pollen - zygote - germ - seed A:
Ans: seed
(Q).
Answer the following question given this paragraph: 4. Ions move through the membrane to maintain electrical neutrality in the cell. In the cell illustrated above, sulfate ions will move from the copper side to the zinc side to compensate for the decrease in Cu 2+ and the increase in Zn 2+ . Q: Ions move through what to maintain electrical neutrality in the cell? Choices: - the plasma - the substrate - the protein - the membrane A:
(A).
the membrane
Ques:Answer the following question given this paragraph: Roundworms may be free-living or parasitic organisms. Free-living worms are found mainly in freshwater habitats. Some live in moist soil. They generally feed on bacteria, fungi, protozoa, or decaying organic matter. By breaking down organic matter, they play an important role in the carbon cycle. Q: By breaking down organic matter, roundworms play an important role in which cycle? Choices: - water cycle - metamorphic cycle - circadian cycle - carbon cycle A:

Ans:carbon cycle

Q: What organ eliminates solid wastes that remain after the digestion of food? Choices: - the spleen - the appendix - the bladder - the large intestine A:
Answer:
the large intestine
