| Question | Answer |
|---|---|
| cells in the body that can divide repeatedly and become other types of cells are called | stem cells |
| the layer of cells that protects the body from dehydration are called | epithelial tissue |
| the heart and lungs are protected by the | rib cage |
| the structure that is not part of the axial skeleton is the | pectoral girdle |
| compact bone contains tightly packed | oseteocytes |
| in an embryo, the skeleton is originally made of | cartilage |
| this is not moved by muscle tissue | signals in the brain |
| the functional unit of muscle contraction is called the | sarcomere |
| blood, bone, and cartilage are examples of | connective tissue |
| the skin is made up of | epithelial tissue |
| from the smallest functional units to the largest, the body is organized as follows | cells, tissues, organs, systems |
| if homeostasis were disrupted, all of the following would occur EXCEPT | the heart would immediately stop pumping blood |
| a person with a broken pelvic bone would probably be unable to | walk or run |
| smooth muscles can be found | in internal organs |
| tendons are bands of tissue that connect | muscles to bones |
| the thin outer layer of the skin is | the epidermis |
| the skin performs all of the following except | production of gametes |
| which structure enables the skin to receive nutrients, eliminate wastes, and regulate body temperature? | blood vessels |
| which of the following is the main function of sweat glands? | regulating body temperature |
| which best describes keratin | a strong, fibrous protein |
| sperm and eggs are both | haploid |
| what is part of the cell theory | cells are the basic units of structure and function in organisms |
| which structure acts as a boundary between the outside environment and the inside of the cell | structure 4 |
| all living things are made of | carbon |
| the scientific study of heredity is called | genetics |
| molecules of DNA are composed of long chains of | nucleotides |
| the amount of guanine in an organism always equals the amount of | cytosine |
| during DNA replication, a complementary strand of DNA is made from each original DNA strand. Thus, if a portion of the original strand is CCTAGCT, then the new strand will be | GGATCGA |
| what is not found in RNA | uracil |
| during transcription, the genetic information for making a protein is "rewritten" as a molecule of | messenger RNA |
| covalent bonds form when | two hydrogen atoms share electrons with one oxygen atom |
| sharing of electrons in the outer energy levels of two atoms | makes both atoms stable |
| the building blocks of most biomolecules contain the element | carbon |
| which molecules are most closely related to proteins | amino acids |
| which molecules are most closely related to nucleic acids | nucleotides |
| what is not part of a nucleotide in a DNA molecule | three phosphate groups |
| a cell contains | thousands of different kinds of enzymes, each assisting in a different chemical reaction |
| which is true of both DNA and some proteins | must be kept separate from cytoplasm |
| what do chloroplasts and mitochondria have in common | production of ATP |
| what level of organization is the small intestine | organ |
| the difference between anaphase of mitosis and anaphase I of meiosis is that | chromatids do not separate at the centromere in anaphase I |
| when an individual heterozygous for a trait is crossed with an individual homozygous recessive for the trait, the offspring produced will | all have the same genotype |
| this is not moved by muscle tissue | signals in the brain |
| a muscle causes a bone to move by | pulling on the bone |
| during light exercise, muscle cells produce ATP by a process that | requires a lot of oxygen |
| the skin DOES NOT perform | production of gametes |
| one characteristic of the dermis of the skin is that it is | involved in temperature regulation |
| in which of the following ways are mature human sperm and egg similar | they both have the same number of chromosomes in their nuclei |
| ovary:egg production:: | testis:sperm production |
| what occurs during the fetal period | the fetus's blood absorbs oxygen and gets rid of carbon dioxide through the placenta |
| the skin is made up of | epithelial tissue |
| organs that work together form | organ systems |
| the heart and the blood vessels are separate organs that form the | circulatory system |
| the point where two or more bones meet is called a | joint |
| tendons are bands of tissue that connect | muscles to bones |
| muscle cells get the energy needed to contract from | ATP |
| which of the following is a skin disorder that results from the blockage of oil glands | acne |
| the testes produce | sperm |
| production of sperm and testosterone is regulated by luteinizing hormone and follicle-stimulating hormone, which are produced by the | pituitary gland |
| a sperm cell consists of a tail used for locomotion, and a head that contains ___________________, which helps the sperm cell penetrate an egg cell. | enzymes |
| the midpiece of a sperm cell contains many _______________, which supply sperm with the energy needed to propel themselves through the female reproductive system. | mitochondria |
| eggs are produced in the | ovaries |
| the entrance to the uterus is called the | cervix |
| if no embryo arrives after the uterus has prepared to receive it, | the lining of the uterus is expelled from the body in menstrual blood |
| menopause is the time at which | females cease to release eggs |
| the burrowing of an embryo into the uterine wall is known as | implantation |
| embryonic cells are organized into the major organ systems | by the end of the first trimester |
| pregnancy is often divided into three 3-month periods known as | trimesters |
| sexually transmitted diseases such as gonorrhea and chlamydia, which are caused by baceteria | can usually be treated with antibiotics |
