AND VERIFIED ANSWERS;
100% CORRECT; GRADE A
Be able to define all the nutrient-related vocabulary
(nutrient, macro- and micronutrient, mineral
macronutrients, essential nutrient, vitamin, mineral). Why
don't plants need to take in vitamins? - correct
answer- Nutrient-substances required for growth
and maintenance. Macro- relatively large requirement.
Micro- requirements usually in ppm.
essential nutrient- cannot be assembled from simple
organic molecules and have to be taken in through diet.
Vitamin- organic compound req. vary.
Mineral- inorganic ions needed by all organisms.
Mineral Macronutrients-cofactors in enzymatic reactions
(ions required for proper functioning)
Be able to explain the fate of monosaccharides, fatty
acids, and amino acids after absorption across the gut
epithelium. By what circulatory pathway do monomers
,travel to body cells? What is the role of the liver in
controlling each of the above monomers? - correct
answer- Monosaccharides (ilium jejunum,
circulatory system, liver stores as glycogen and gives as
glucose); Fatty Acids (ilium jejunum, circulatory system,
liver, cellular respiration or adipose tissue OR ilium
jejunum, lymphatic system CR); Amino acids (ilium
jejunum, circulatory system, liver, use it or lose it)
Be able to recognize and explain the location of the fungal
hyphae of both ectomycorrhizae and endomycorrhizae. -
correct answer- Look at pictures on powerpoint.
Be able to recognize epidermis, parenchyma, endodermis,
xylem, and phloem on a root cross section photo. -
correct answer- look at cross section of root
Be able to recognize members of all the classes of
vertebrates. Which class has the most species? Know
which classes have members who lay eggs in water and
which have members who can lay eggs on land. What is
unique about mammals? - correct answer-
Agnatha, chondrichthyes, osteichthyes, amphibia, reptilia,
, aves, mammalia. osteichthyes. amphibia lays eggs in
water and reptilia lays on land. mammals have mammary
glands.
Be able to recognize representative members of each
phylum discussed in class. There will be some
identification questions on the practical part of the exam
(photos). - correct answer-
Be able to recognize the notochord and dorsal nerve cord
on an amphioxus photo. - correct answer- yes
Define a coelom. - correct answer- fluid filled
body cavity
Ensure that you can pluralize and singularize words that
end in the Latin endings discussed in class.Remember that
'genus' is an exception because the plural form is 'genera'.
- correct answer- Singular: a, us, um, is
Plural: ae, i, a, es
