Answer the following question given this paragraph: 1. The first step in eukaryotic cell division, as it is in prokaryotic cell division, is DNA replication. As you can see in Figure below , each chromosome then consists of two identical copies. The two copies are called sister chromatids. They are attached to each other at a point called the centromere. Q: Dna replication is the first step in what process for both eukaryotic and prokaryotic cells? Choices: - cell death - cell growth - cell transfer - cell division A:
cell division

Answer the following question given this paragraph: The Prokaryotic Cell Recall that prokaryotes (Figure 22.10) are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus but instead generally have a single chromosomea piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane. Q: Prokaryotic cells do not have a nucleus but instead generally have a single chromosome, a piece of double-stranded dna located in an area of the cell called the what? Choices: - lysosome - cytoplasm - spicule - nucleoid A:
(Answer)
nucleoid
Ques: Answer the following question given this paragraph: Check Your Understanding Define nodes and antinodes. Solution Nodes are areas of wave interference where there is no motion. Antinodes are areas of wave interference where the motion is at its maximum point. Q: Solution nodes and antinodes are both areas of wave interference, but they differ in the presence of what condition? Choices: - radiation - gravity - speed - motion A:
Ans: motion

Answer the following question given this paragraph: The ilium is the fan-like, superior region that forms the largest part of the hip bone. It is firmly united to the sacrum at the largely immobile sacroiliac joint (see Figure 8.12). The ischium forms the posteroinferior region of each hip bone. It supports the body when sitting. The pubis forms the anterior portion of the hip bone. The pubis curves medially, where it joins to the pubis of the opposite hip bone at a specialized joint called the pubic symphysis. Q: What is the fan-like superior region that forms the largest part of the hip bone and is united to the sacrum at the largely immobile sacroiliac joint? Choices: - spine - pica - septum - ilium A:
(A).
ilium
Ques:Answer the following question given this paragraph: The sample in an experiment or other investigation consists of the individuals or events that are studied. Typically, the sample is much smaller than all such individuals or events that exist in the world. Whether the results based on the sample are true in general cannot be known for certain. However, the larger the sample is, the more likely it is that the results are generally true. Similarly, the more times that an experiment is repeated and the same results obtained, the more likely the results are valid. This is why scientific experiments should always be repeated. Q: What part of an experiment or other investigation consists of the individuals or events that are studied? Choices: - hypothesis - experimental control - independent variable - sample A:

Ans:sample
Ques: Answer the following question given this paragraph: The sun's energy is converted to chemical energy by a plant. An animal gets energy when it eats the plant. The student gets energy when it eats the animal. The boy's energy is used to pedal the bike. Q: The sun's energy is converted to chemical energy by a what? Choices: - bacterium - mammal - amphibian - plant A:
Ans:
plant
