Answer the following question given this paragraph: Force is defined as a push or pull acting on an object. There are several fundamental forces in the universe, including the force of gravity, electromagnetic force, and weak and strong nuclear forces. When it comes to the motion of everyday objects, however, the forces of interest include mainly gravity, friction, and applied force. Applied force is force that a person or thing applies to an object. Q: Push or pull acting on an object is also called? Choices: - Gravity. - space - effort - force A:
(Answer)
force
Ques: Answer the following question given this paragraph: The bacterium in Figure above is a prokaryote. Prokaryotes are microscopic organisms that have neither a membrane-bound nucleus nor membrane-bound organelles. Some cell biologists consider the term "organelle" to describe membrane-bound structures only, whereas other cell biologists define organelles as discrete structures that have a specialized function. Prokaryotes have ribosomes, which are not surrounded by a membrane but do have a specialized function, and could therefore be considered organelles. All metabolic functions carried out by a prokaryote take place in the plasma membrane or the cytosol. Q: All metabolic functions carried out by a prokaryote take place in the plasma membrane or where else? Choices: - extracellular - Shell - mitochondrial - cytosol A:
Ans: cytosol
(Q).
Answer the following question given this paragraph: Q: If environmental conditions deteriorate, many species can form protective what? Choices: - fibers - proteins - shells - cysts A:
(A).
cysts
Ques:Answer the following question given this paragraph: The electrical potential difference between the two plates is expressed as , the electric field strength times the distance between the plates. The units in this expression are Newtons/coulomb times meters, which gives the final units Joules/coulomb. Voltage is an expression of the amount of potential energy per unit charge. The work done moving a charge against the field can be calculated by multiplying the electric field potential by the charge, . Q: What is it called when a charge moves against a field? Choices: - momentum - power - force - work A:

Ans:work
Answer the following question given this paragraph: The reproductive system in both males and females consists of structures that produce reproductive cells, or gametes, and secrete sex hormones. A gamete is a haploid cell that combines with another haploid gamete during fertilization. Sex hormones are chemical messengers that control sexual development and reproduction. The male reproductive system consists of structures that produce male gametes called sperm and secrete the male sex hormone testosterone. Q: What system in both males and females consists of structures that produce reproductive cells, or gametes, and secrete sex hormone? Choices: - circulatory system - immune system - digestion - reproductive A:
reproductive
