all

Answer 2

organic compounds

Question 3

In humans, lactose is broken down into glucose and
galactose in the presence of a particular enzyme. It is
most likely that the enzyme that breaks down lactose

Answer 3

is not involved in other types of reactions
because enzymes are specific

Question 4

that directly form some of the complex organic
molecules present in humans?

Answer 4

glucose and amino acids

Question 5

An energy-rich organic compound needed by
organisms is

Answer 5

glucose

Question 6

The building blocks for this molecule are

Answer 6

simple surgars

Question 6

energy in this molecule is stored

Answer 6

in the bonds between atoms

Question 6

The energy required to assemble proteins and fats is
directly supplied to body cells from

Answer 6

molecules of ATP contained within the cells

Question 7

Base your answer to the following question on the
Which conchasion can best be made from this
information?
diagram below, which represents stages in the
digestion of a starch, and on your knowledge of
biology

Answer 7

simple sugars

Question 8

There are over 2000 kinds of edible insects in the
world, and they are becoming an increasingly
popular source of protein. One cup of cricket flour
contains over 28 grams of protein. The building
blocks of the protein in cricket flour are

Answer 8

amino acids

Question 9

Scientists have found a gene that makes a protein
called PKG that controls certain behaviors in many
Al all the colors of visible light
5 molecules of ATP contained within the cells
C) all the DNA found in sex cells
D) molecules of carbon divide produced by
chloroplasts
types of ants. The soldier ant will help collect food
when it has a low level of PKG. When it has a high
level of PKG, the soldier ant will protect amd detend
its colony, Soldier ants that are given PNG are more
likely to ignore food sources and attack intraders
10. Base your answer to the following question on the
Which conchasion can best be made from this
information?

Answer 9

The behavior of soldier ants is controlied in
part by the PKG protein.
