Question 0

Bryophytes (29)

Answer 0

Plants that have no vascular tissue

Question 1

Mycorrhizae (29)

Answer 1

Symbionts that live in the roots of most plants and help in the uptake of nutrients

Question 2

Legumes (29)

Answer 2

A group of plants that have symbionts (nitrogen-fixing bacteria) living in their roots

Question 3

Malpighian tubules (29)

Answer 3

Structures found in insects that aid in excretion; they excrete nitrogenous waste into the digestive tract and, from there, out of the body

Question 4

Flame cell (29)

Answer 4

A structure for excretion in flatworms like planaria

Question 5

Nematocysts (29)

Answer 5

Stingers found in organisms like hydra

Question 6

Cambium (29)

Answer 6

Growth tissue in plants located between the xylem and phloem; it is always dividing; a specific type of meristematic tissue

Question 7

Insulin (30)

Answer 7

A protein made of amino acids

Question 8

SO2

Answer 8

Mixes with water vapor to create sulfurous acid and sulfuric acid that creates acid rain

Question 9

Cnidarians (30)

Answer 9

Primitive animals that exhibit radial symmetry; are two cell layers thick and do not undergo embryonic development like flatworms and more advanced animals

Question 10

Flatworms (30)

Answer 10

Acoelomates that do not have a coelom or body but have a head

Question 11

Auxins (30)

Answer 11

Responsible for tropisms and apical dominance

Question 12

Translation (30)

Answer 12

Process by which codons of an mRNA sequence are changed into an amino acid sequence; occurs at the ribosomes

Question 13

Transcription (30)

Answer 13

Process by which DNA makes RNA; occurs in the nucleus

Question 14

Transformation (39)

Answer 14

Process where bacteria absorb genes from other bacteria; discovered by Griffith in 1927

Question 15

Lacteal (31)

Answer 15

Part of the lymphatic system; absorbs fatty acids and glycerol

Question 16

Villus (31)

Answer 16

Lines the small intestine and creates a fuzzy appearance called a brush border; enhances absorption into the bloodstream by increasing surface area

Question 17

Capillary [in the villus] (31)

Answer 17

Absorbs monosaccharides and amino acids

Question 18

Islets of Langerhans (31)

Answer 18

Contains special cells that release either glucagon (raises blood sugar) or insulin (lowers blood sugar); found in the pancreas

Question 19

Hypothalamus (31)

Answer 19

Bridge between the nervous (electrically stimulates anterior pituitary to release hormones) and endocrine system (produces and releases oxytocin and ADH that are stored in the posterior pituitary until needed)

Question 20

Plasmolysis (32)

Answer 20

Cell shrinking due to loss of water from a cell

Question 21

Translation (33)

Answer 21

Process by which DNA carried by mRNA from the nucleus is changed into and amino acid sequence, a polypeptide, at the ribosomes
