Answer the following question given this paragraph: Some animals communicate with scent. They release chemicals that other animals of their species can smell or detect in some other way. Ants release many different chemicals. Other ants detect the chemicals with their antennae. This explains how ants are able to work together. The different chemicals that ants produce have different meanings. Some of the chemicals signal to all of the ants in a group to come together. Other chemicals warn of danger. Still other chemicals mark trails to food sources. When an ant finds food, it marks the trail back to the nest by leaving behind a chemical on the ground. Other ants follow the chemical trail to the food. Q: What part of the body do ants use to detect chemicals? Choices: - thorax - fins - eyes - antennae A:
antennae

Answer the following question given this paragraph: Each substance can be classified as an ionic solute or a nonionic solute. Ionic solutes are electrolytes, and nonionic solutes are nonelectrolytes. Potassium chloride is an ionic compound; therefore, when it dissolves, its ions separate, making it an electrolyte. Fructose is a sugar similar to glucose. (In fact, it has the same molecular formula as glucose. ) Because it is a molecular compound, we expect it to be a nonelectrolyte. Isopropyl alcohol is an organic molecule containing the alcohol functional group. The bonding in the compound is all covalent, so when isopropyl alcohol dissolves, it separates into individual molecules but not ions. Thus, it is a nonelectrolyte. Magnesium hydroxide is an ionic compound, so when it dissolves it dissociates. Thus, magnesium hydroxide is an electrolyte. Q: What are ionic solutes? Choices: - solvent - salts - carbohydrates - electrolytes A:
(Answer)
electrolytes
Ques: Answer the following question given this paragraph: In prophase II, once again the nucleolus disappears and the nucleus breaks down. The chromatin condenses into chromosomes. The spindle begins to reform as the centrioles move to opposite sides of the cell. Q: In which stage does the chromatin condense into chromosomes? Choices: - Metaphase I - Telophase II - Anaphase I - prophase ii A:
Ans: prophase ii
(Q).

The X and Y sex chromosomes are shown in the box. Q: X and y are the labels of what specialized human chromosomes? Choices: - carb chromosomes - exotic chromosomes - protein chromosomes - sex chromosomes A:
(A).
sex chromosomes
Ques:Answer the following question given this paragraph: There are two cell types: prokaryotes and eukaryotes. Prokaryotic cells are usually single-celled and smaller than eukaryotic cells. Eukaryotic cells are usually found in multicellular organisms, but there are some single-celled eukaryotes. Q: What are the two types of cells? Choices: - mammal and plant - bacteria and eukaryotes - animal and bacteria - prokaryotes and eukaryotes A:

Ans:prokaryotes and eukaryotes
Ques: Answer the following question given this paragraph: Q: What are a group of protists whose monophyly is well supported by molecular systematics? Choices: - euglenozoa - sporozoans - mycetozoa - alveolates A:
Ans:
alveolates
