QuestionAnswer
water molecules cling to one another, resulting in surface tension that allows an insect like a water strider to skate across its surface because of covalent bonds between the water molecules false
the strongest type of chemical bond is covalent bond true
a polar covalent molecule is formed when electrons are not shared equally in the molecule true
carbon predominates as the most common element in the body of living or organic organisms because it is the strongest element and will not breakdown easily false
a base is any substance that releases or gives off hydrogen ions false
the type of chemical reaction that puts organic compounds together by joining monomers into polymers is called a hydrolysis reaction false
unsaturated fats include plant and fish fats that are liquid at room temperature and healthier in our diet true
the primary molecule storing sugar in our bodies and other animals for later use as energy is glycogen true
DNA, RNA, and ATP are all types of nucleic acids true
phospholipids are the primary type of molecule used to build cell membrane structure true
rough endoplasmic reticulum differs from smooth endoplasmic reticulum in having a wavy surface that gives it more surface area so that it can increase the rate of photosynthesis in a plant cell false
the ufnction of ribosomes is to make proteins true
the atomic number is the number of protons plus the number of electrons in an atom false
protons and electrons have opposite charges, but have a molecular weight or mass of one false
atoms are neutral in charge, but have ions have a charge true
a buffer is a substance that counteracts shifts in pH. true
living things can be distinguished from nonliving things because they have no movement false
viruses contain DNA, can infect other organisms, and can be spread, and so are considered to be alive false
both creation science and macroevolution are known as empirical or operation sciences, which means that past events are being studied that cannot be tested directly false
prokaryotic cells like bacteria do not have a nucleus true
most digestion of food occurs in the stomach false
the function of bile that is stored in the gall bladder is to lower the acidity of the liquefied food that leaves the stomach into the small intestine false
humans have a double circulation where the systemic circulation is blood going to the lungs and the pulmonary circulation is blood going to the body false
the job of platelets in the blood is to help fight infections false
veins carry blood to the heart and arteries carry blood away from the heart true
arteries have thicker walls and more elasticity or stretch than veins in order to withstand blood pressure true
in a heart, blood enters through the ventricles and leaves through the atria false
in an endergonic reaction, the products made have more energy than the reactants, so energy has been stored or put into the products true
photosynthesis is an example of a degradative pathway false
in aerobic respiration most of the energy in the form of ATP molecules is produced during the Krebs Cycle false
alcoholic fermentation by yeast is an example of anaerobic respiration true
aerobic respiration produces more ATP from one molecule of glucose than anaerobic respiration does true
when we inhale the ribs move in, the diaphragm moves up, and our chest cavity decreases in size false
the autonomic nervous system sends impulses to the voluntary skeletal body muscles, allowing us to move true
"fight or flight" responses of the body that involve physical activity such as dealing with emergencies are under the control of the sympathetic portion of the nervous system true
the primary function of muscle tissue in our body is protection false
if the body is becoming dehydrated one response of the body to correct this is to cause the permeability of the loop of Henle to decrease, so that less water osmoses out of the urine into the blood false
triggering of thirst by the body is a common response to help deal with the problem of high blood pressure false
the most common type of feedback to control the extent of a response in the body is negative feedback true
the type of nerve cell that takes impulses or information from the central nervous system to a muscle or an organ so that action can be taken is a motor neuron true
nonmalignant tumors are likely to have localized growth and to not spread unchecked to other parts of the body true
surgery is an appropriate treatment for nonmalignant cells in our body true
when mendel crossed a purple flowered pea plant with a white flowered one he found that in the F1 generation 20% of offspring showed the recessive trait, and in the F2 generation 100% showed the dominant trait false
cytokinesis is the part of the cell cycle when the division of the cell cytoplasm into two cells takes place true
sperm and egg cells produced in Meiosis contain the haploid number of chromosomes true
when one cell goes through Meiosis the cells produced are genetically identical, or clones false
when a cell goes through Mitosis that one cell in the process of dividing becomes four cells false
meiosis occurs only in germ cells of reproductive organs true
In the structure of DNA, the nucleotide base guanine (G) always pairs with adenine (A) false
DNA making RNAis known as translation false
translation takes place outside the nucleus true
fewer sperm are produced and more of them have developmental defects when they develop at the normal body temperature of 98.6 F true
the hormone that causes the release of an egg when its levels surge is known as LH or lutenizing hormone true
an advantage of external fertilization is that the embryo is protected and that there is less waste of egges false
the function of the epididymus is to mature and store the sperm true
typical birth control pills work primarily by preventing the release of FSH and LH, so that an egg is not released and so cannot be fertilized true
conducting tissue in plants that takes sugars down to the roots is xylem, and conducting tissue in plants that brings nutrients and water up to the leaves is phloem false
flowering plants, conifer trees, and ferns are all vascular plants true
angiosperms are the group of plants that includes all flowering plants true
a fruit is a plant product that is usually produced from the flowers true
the primary color of light that is captured by the chlorophyll of plants and used to power photosynthesis is green false
an abiotic factor in the environment is anything that is living false
the type of population regulation that is common in most species, because of the fact that resources are always limiting, is density-independenct regulation false
human population growth has been showing an exponential growth pattern most recently true
if a hawk and a fox are competitors for the same type of food in an area, mice, then they are classified as intraspecific competitors false
if a starling takes over the nest cavity of a woodpecker in a tree or a cactus and keeps that woodpecker from using that nest cavity, then this would be classified as exploitative competition false
if a number of animals nest on and inside a saguaro cactus and benefit from it without either benefiting or harming the cactus, then this would be classified as a mutualism false
a group of different species living together in a location such as a forest or pont, plus the nonliving or physical part of their environment, is known as a community false
perserving a smaller number of habitat areas that are large in size is generally a better conservation strategy than perserving a larger number of habitat areas that are all relatively small true
levels of CO2 have been increasing in the atmosphere in recent decades true
energy flows one way in ecosystems and must be replaced, while nutrients are recycled and reused continually true
the change in a population of peppered moths from nearly all white individuals to almost all dark individuals is an example of disruptive selection false
early greek and chinese cultures developed the first basic concept fo the evolutionary development of organisms false
the theory of the inheritance of acquired characteristics says that through use or disuse, parts of an animal's body can develop or degenerate, and that these changes can be passed on to its offspring true
one type of animal that charles darwin saw on the Galapagos Islands that influenced his thinking and led to his theory of natural selection was the mockingbird true
genetic change in a population over time that requires new genetic variation or information to arise through beneficial mutations is known as microevolution false
according to evolutionary theory, oxygen was a common gas of the earth's early atmosphere that allowed the evolution of the first life false
a problem with claiming that the results of the spark discharge experiment support the idea that life arose from natural chemical reactions is that there was no adequate type of energy source proposed false
the finding of iridium layers in certain sediment layers in the earth has been proposed as evidence for continental drift false
the finding of tektites, or shock formed glass present in certain locations and sediments has been proposed as evidence that mega meteorites have struck the earth and could have caused mass extinctions true
