Answer the following question given this paragraph: Of the three basic types of emissions, gamma radiation has the highest penetrating power. Thick, high density materials (such as lead) are required to stop gamma emissions. The thickness of the shielding will determine the effectiveness of the protection offered by the lead. Q: Of the three basic types of emissions, which has the highest penetrating power? Choices: - ultraviolet radiation - fluid radiation - chemical radiation - gamma radiation A:
(Answer)
gamma radiation
Ques: Answer the following question given this paragraph: These two tracts connect the hypothalamus with the major parasympathetic nuclei in the brain stem and the preganglionic (central) neurons of the thoracolumbar spinal cord. The hypothalamus also receives input from other areas of the forebrain through the medial forebrain bundle. The olfactory cortex, the septal nuclei of the basal forebrain, and the amygdala project into the hypothalamus through the medial forebrain bundle. These forebrain structures inform the hypothalamus about the state of the nervous system and can influence the regulatory processes of homeostasis. A good example of this is found in the amygdala, which is found beneath the cerebral cortex of the temporal lobe and plays a role in our ability to remember and feel emotions. Q: What also receives input from other areas of the forebrain through the medial forebrain bundle? Choices: - hippocampus - pituitary gland - optic chiasm - hypothalamus A:
Ans: hypothalamus

Answer the following question given this paragraph: The adult human skeleton has 206 bones, some of which are named below ( Figure below ). Bones are made up of living tissue. They contain many different types of tissues. Cartilage, a dense connective tissue, is found at the end of bones and is made of tough protein fibers. Cartilage creates smooth surfaces for the movement of bones that are next to each other, like the bones of the knee. Q: On what part of bones would you expect to find cartilage? Choices: - interior - marrow - exterior - end A:
(A).
end
Ques:Answer the following question given this paragraph: Quantities in science may be very large or very small. This usually requires many zeroes to the left or right of the decimal point.

Ques:Answer the following question given this paragraph: 42.3 | Antibodies By the end of this section, you will be able to: Explain cross-reactivity Describe the structure and function of antibodies Discuss antibody production An antibody, also known as an immunoglobulin (Ig), is a protein that is produced by plasma cells after stimulation by an antigen. Antibodies are the functional basis of humoral immunity. Antibodies occur in the blood, in gastric and mucus secretions, and in breast milk. Antibodies in these bodily fluids can bind pathogens and mark them for destruction by phagocytes before they can infect cells. Q: What protein is produced when a plasma cell is stimulated by antigens? Choices: - collagen - dystrophin - keratin - immunoglobulin A:

Ans:
immunoglobulin
