Answer the following question given this paragraph: A community is the biotic component of an ecosystem. It consists of the populations of all the species that live in the same area. Populations in communities often interact with each other. Community interactions are important factors in natural selection. They help shape the evolution of the interacting species. Types of community interactions include predation, competition, and symbiosis. You'll read about each type of interaction in this lesson. Q: Community interactions are important factors in what? Choices: - natural process - natural change - natural resources - natural selection A:
natural selection

Answer the following question given this paragraph: Bacteria reproduce through a process called binary fission . During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells. The two daughter cells are identical to the parent cell. Binary fission can happen very rapidly. Some species of bacteria can double their population in less than ten minutes! This process makes it possible for a tremendous bacterial colony to start from a single cell. Q: Bacteria reproduce through what process? Choices: - binary fusion - tertiary fission - residual fission - binary fission A:
(Answer)
binary fission
Ques: Answer the following question given this paragraph: Haumea is the third-brightest Kuiper belt object. Haumea has two moons. Haumea's odd oval shape is probably caused by its extremely rapid rotation. It rotates in just less than 4 hours! Like other Kuiper belt objects, Haumea is covered by ice. Its density is similar to Earth's Moon, at 2.6 3.3 g/cm 3 . This means that most of Haumea is rocky. Q: Haumea, which is the third brightest kuiper belt object has an odd oval shape which is probably caused by what? Choices: - unusually rapid rotation - particularly rapid rotation - Slow rotation - extremely rapid rotation A:
Ans: extremely rapid rotation
(Q).
Answer the following question given this paragraph: The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows. The greater each of these factors is, the bigger a wave will be. Some of the biggest waves occur with hurricanes. A hurricane is a storm that forms over the ocean. Its winds may blow more than 150 miles per hour! The winds also travel over long distances and may last for many days. Q: Some of the biggest waves occur with what type of storm that forms over the ocean and brings high winds? Choices: - tropical depression - tsunami - tropical storm - hurricane A:
(A).
hurricane
Ques:Answer the following question given this paragraph: Many mucous membranes are also covered with cilia. These are tiny, hair-like projections. Cilia move in waves and sweep mucus and trapped pathogens toward body openings. You can see this in the diagram in Figure below . When you clear your throat or blow your nose, you remove mucus and pathogens from your body. Q: What are tiny, hair like projections? Choices: - fuzz - spinicles - actin - cilia A:

Ans:cilia
Ques:Answer the following question given this paragraph: Identify features caused by groundwater erosion and deposition. Q: Water infiltrates the ground because soil and rock may have air spaces between the grains. these pores, or tiny holes, result in the rock's what? Choices: - sheen - energy - shine - porosity A:

Ans:
porosity
