Quarterly Test 2

Question 1

a genotype in which both alleles are identical

Answer 1

homozygous genotype

Question 2

a genotype with two different alleles

Answer 2

heterozygous genotype

Question 3

What are gametes produced in animal males called

Answer 3

sperm

Question 4

If a plant cell needs energy for endocytosis, what does it use and where does the energy come from?

Answer 4

ATP supplies the energy of a plant cell needs for endocytosis

Question 5

What change to the concept of macroevolution did Neo-Darwinism make?

Answer 5

muttion

Question 6

What is the difference between a gamete and a normal cell?

Answer 6

A gamete is a haploid while a normal cell is diploid

Question 7

What are the four stages of cellular respiration?

Answer 7

glycolysis, the link reaction, the Krebs cycle, and the electron transport chain

Question 8

List (in order) all the stages of meiosis.

Answer 8

prophase I, metaphase I, anaphase I, telophase i, prophase II, metaphase II, anaphase II, telophase II

Question 9

Which state of cellular respiration produces the most energy?

Answer 9

the electron transport chain

Question 10

How would an adherent to punctuated equilibrium explain the lack of intermediate links in the fossil record?

Answer 10

An adherent to punctuated equilibrium would say that since the transition from species to species takes such a short amount of time, there is virtually no chance of intermediate link being fossilized.

Question 11

How is ATP made during fermentation?

Answer 11

from glycolysis without oxygen

Question 12

If the homologous chromosomes of a tetrad fail to separate

Answer 12

half the gametes formed will have an extra chromosome and the other half will lack a chromosome

Question 13

What are the two phases of protein synthesis?

Answer 13

transcription and translation

Question 14

Is fermentation aerobic or anaerobic?

Answer 14

anaerobic

Question 15

What are gametes produced in animal males called

Answer 15

eggs

Question 16

Haploid is the number of

Answer 16

homologous pairs.

Question 17

When one of the gamete fuses with a normal gamete during fertilization,

Answer 17

the offspring will have an abnormal number of chromosomes in its cells

Question 18

What are the reactants of photosynthesis?

Answer 18

Carbon dioxide and water

Question 19

XY chromosome

Answer 19

male

Question 20

Why is ATP better suited to provide the energy for cellular activities than glucose?

Answer 20

ATP stores just the right amount of energy to power cellular activities.

Question 21

How do you find the haploid number?

Answer 21

Divide the diploid number by 2

Question 22

How does the study of structural homology provide evidence against macroevolution?

Answer 22

the similar structures are determined by quite different genes

Question 23

What happens during the translation phase of protein synthesis?

Answer 23

Translation occurs in the cytoplasm at a ribosome where amino acid carry tRNAs meet the mRNA to produce a protein

Question 24

What does a restriction enzyme do?

Answer 24

a genetic “tool” used to cut DNA

Question 25

What are the products of photosynthesis?

Answer 25

glucose and oxygen

Question 26

What happens during the transcription phase of protein synthesis?

Answer 26

Transcription occurs in the nucleus and mRNA makes a negative image in order to copy a portion of DNA.

Question 27

The only stage that does not require oxygen

Answer 27

glycolysis

Question 28

XX chromsomes

Answer 28

female

Question 29

List (in order) all the stages of meiosis.

Answer 29

prophase, metaphase, anaphase, and telophase
