Q: What is transmitted that makes up the electromagnetic spectrum? Choices: - gamma rays - light waves of different wavelengths - sound waves of different frequencies - electromagnetic radiation in different wavelengths A:
(Answer)
electromagnetic radiation in different wavelengths
Ques: Answer the following question given this paragraph: Sepals protect the developing flower while it is still a bud. Sepals are usually green, which camouflages the bud from possible consumers. Q: What protects a developing flower while it is still a bud? Choices: - shell - petals - lobes - sepals A:
Ans: sepals
(Q).
Answer the following question given this paragraph: Complement An array of approximately 20 types of proteins, called a complement system, is also activated by infection or the activity of the cells of the adaptive immune system and functions to destroy extracellular pathogens. Liver cells and macrophages synthesize inactive forms of complement proteins continuously; these proteins are abundant in the blood serum and are capable of responding immediately to infecting microorganisms. The complement system is so named because it is complementary to the innate and adaptive immune system. Complement proteins bind to the surfaces of microorganisms and are particularly attracted to pathogens that are already tagged by the adaptive immune system. This "tagging" involves the attachment of specific proteins called antibodies (discussed in detail later) to the pathogen. When they attach, the antibodies change shape providing a binding site for one of the complement proteins. After the first few complement proteins bind, a cascade of binding in a specific sequence of proteins follows in which the pathogen rapidly becomes coated in complement proteins. Complement proteins perform several functions, one of which is to serve as a marker to indicate the presence of a pathogen to phagocytic cells and enhance engulfment. Certain complement proteins can combine to open pores in microbial cell membranes and cause lysis of the cells. Q: Which proteins bind to the surfaces of microorganisms and are particularly attracted to pathogens that are already tagged by the adaptive immune system? Choices: - attractive proteins - mobilize proteins - whereby proteins - complement proteins A:
(A).
complement proteins
Ques:Answer the following question given this paragraph: The subfield of thermochemistry studies the energy changes that occur over the course of various chemical reactions. We will first look at how these changes are measured and then go into quantitative descriptions of heat transfer. Calorimetry is a term used to describe the measurement of heat transfers, usually by monitoring changes in the temperature of an isolated system. A calorimeter is a device used to measure temperature changes during chemical processes. The simplest type of calorimeter is the constant-pressure device illustrated in Figure below . Q: What is a device used to measure temperature changes during chemical processes called? Choices: - altimeter - alethiometer - thermometer - calorimeter A:

Ans:calorimeter
Answer the following question given this paragraph: events in angiosperms are known as double fertilization (Figure 32.18). After fertilization is complete, no other sperm can enter. The fertilized ovule forms the seed, whereas the tissues of the ovary become the fruit, usually enveloping the seed. Q: After fertilization is complete, no other sperm can enter. the fertilized ovule forms the seed, whereas the tissues of the ovary become this? Choices: - plant - wheat - vegetables - fruit A:
fruit
