What part of a cell combines amino acids into proteins? a. ribosome b. chloroplast c. mitochondria d. nucleoplasm |
a. ribosome |
The ribosome is the part of a cell that combines amino acids into proteins. |
|
|
What is the term for the process in which a cell converts nutrients into energy? a. metabolism b. cellular respiration c. photosynthesis d. osmosis |
b. cellular respiration |
Cellular respiration is the process during which a cell produces energy by breaking down nutrients within the cell. Cellular respiration is more correct than Choice (A) because metabolism involves not only breaking down nutrients but also building molecules. Choice (B) is more specific. |
|
|
Which process occurs when carbon dioxide and water are converted into glucose and oxygen? a. metabolism b. cellular respiration c. photosynthesis d. osmosis |
c. photosynthesis |
Photosyntheis occurs in plants when they use sunlight to make energy by converting carbon dioxide and water into glucose and oxygen. |
|
|
What term describes when water or another solvent moves through the cell membrane? a. metabolism b. cellular respiration c. photosynthesis d. osmosis |
d. osmosis |
Osmosis occurs when a solvent, such as water, moves through the cell membrane in order to equal out the solvent concentrations on either side. |
|
|
What term describes when one nucleus of a cell divides, forming two? a.metabolism b. mitosis c. recession d. division |
b. mitosis |
Mitosis occurs when the nucleus of a cell divides to form two cells with identical chromosomes. |
|
|
What term describes the division of cells to create egg cells and sperm cells? a. meiosis b. mitosis c. metabolism d. mitochondria |
a. meiosis |
Meiosis occurs when a cell divides to form egg or sperm cells. Each parent cell divides into four cells, also dividing up the chromosomes so that when an egg and sperm cell join at fertilization, they add up to the appropriate number of chromosomes (for humans, 46) |
|
|
What do the father's sex chromosomes determine about his offspring during reproduction? a. the color of the offspring's hair b. the color of the offspring's eyes c. whether the offspring is a boy or girl d. whether the offspring will have genetic defect. |
c. whether the offspring is a boy or girl |
The mother's sex chromosomes contain only X chromosomes, while the father contributes either an X or a Y, which determines the sex of the offspring. |
|
|
What term is used to describe a gene that is not strong enough to express itself? a. dormant b. dominant c. recessive d. progressive |
c. recessive |
Genes come in pairs, and one gene is always more likely to express itself than the other. The stronger gene is known as the dominant gene, while the other is consider recessive. |
|
|
Which of the following terms refers to the functional unit of inheritance that controls the transmission of one or more traits in the human body? a. DNA b. gene c. cells d. chromosome |
b. gene |
A gene is found in DNA and located on a chromosome, and it is responsible for controlling the inheritance of traits in the human body. |
|
|
What is the term for a small space in the cells of an organism that contains fluid? a. chromatin b. ribosome c. mitochondria d. vacuole |
d. vacuole |
a vacuole is more or less a storage area of fluid within the cytoplasm of a cell. |
|
|
What parts of a cell are rich in fats,, proteins, and enzymes? a. chromatin b. ribosome c. mitochondria d. vacuole |
c. mitochondria |
Mitochondria re found in the cytoplasm of a cell; they produce energy for the cell using stored fats, proteins, and enzymes. |
|
|
Which term refers to the collection of veins that join together to form a large vessel that collects blood from the heart muscle? a. right ventricle b. left atrium c. coronary sulcus d. coronary sinus |
d. coronary sinus |
The coronary sinus is collection of veins that forms a large vessel to collect blood from the heart muscle. |
|
|
What tissue separates the atria from the ventricles in a mammalian heart? a. endocardium b. cardiac skeleton c. fibrous pericardium d. intravenous tubercle |
b. cardiac skeleton |
Although the cardiac skeleton isn't real bone, it does separate and support the atria and general structure of the heart.
|
|
|
Where is the aorta of the heart located in the body? a. from the neck to the heart b. from the heart to the abdomen c. from the heart to the leg d. only in the heart |
b. from the heart to the abdomen |
The aorta, the largest artery in the body, originates at the left ventricle of the heart and extends down to the abdomen. |
