Question 1^8 / 8^ pts Your Answer: In a few sentences, summarize Darwin’s theory of natural selection. that too many offsprings were produced than an environment could support would lead to offspings without desirable traits would not survive versus the ones with the desireable traits in the environment.

Question 3^6 / 6^ pts Your Answer: Are preformation and epigenesis the same thing? Explain why or why not. no they are not the same because epigenesis contradicts preformation in which by epigenesis meaning a fertalized human egg undergoes a specific developmental events that leads to human formation while preformation means fertilized eggs contained a small version of a completly developed adult Preformation postulated that a fertilized egg contained a miniaturized version of a tiny human. Epigenesis directly contradicted that theory by stating that a fertilized egg undergoes a series of developmental events that eventually form a human. Question 4^6 / 6^ pts Match each word with its correct definition. Diploid number The number of chromosomes an organism carries (2n) Correct!Correct! Correct!Correct! Phenotype

An observable feature of a gene Correct!Correct! Genotype (^) The set of alleles that produces a certain trait Correct!Correct! Alleles (^) Alternative forms of genes caused by mutations Correct!Correct! Gene (^) Basic unit of heredity passed from parent to offspring Correct!Correct! Chromosome (^) Exists in pairs within the nucleus of a cell Question 5^2 / 2^ pts Your Answer: What type of plants did Gregor Mendel use in his famous experiments? pea plants Pea plants

Nucleotides Question 8^4 / 4^ pts Your Answer: Modern agriculture has benefited from the use of biotechnology through the use of transgenic crops. What does this mean? it is used to improve crop yields by enhancing the crops tolerance to inscects, harsh environments and more Transgenic plants have been engineered to resist insects and harsh environments, grow bigger and more prolifically, or enhance nutrition. Question 9^2 / 2^ pts True or False: The theory of spontaneous generation posits that living things can spontaneously generate from nonliving things. True Correct!Correct!

False Question 10^6 / 6^ pts Your Answer: Natural selection posits that organisms that have the most advantageous characteristics will survive their environment. Do humans have the same selective pressures for natural selection that their animal counterparts do? Are humans still evolving? in this day and age humans dont have the same slective pressures for natural selection like animals because ofthe advancement and technology so we dont have to hunt for food and other things. and yes humans are still evolving

Question 12^2 / 2^ pts Charles Darwin’s publication on evolution is called: Correct!Correct! The Origin of Species Evolution in a Modern Age The Origin of Mankind The Theory of Relativity Question 13^6 / 6^ pts Your Answer: Propose examples of certain traits that could benefit an animal that lives in a forested environment. sharp nails ability to climb trees ability to fly able to camoflouge

The ability to be camouflaged in trees to hunt or hide, the ability to climb trees or move agilely among tree branches, or the ability to have keen senses when you can’t see very far are all traits that would benefit a forest animal. Answers may vary. Question 14^4 / 4^ pts Your Answer: The _________hypothesized that heredity and development depend on the passing of genetic information via _______that are contained within chromosomes. chromosomaltheory of inheritance genes Chromosomal theory of inheritance; genes Question 15^4 / 4^ pts Humans have a ______ number of 46, with a ______number of

Your Answer: guanine thymine cytosine adenine pairs are A=T and G=C ATCG; A- T and C-G Question 18^6 / 6^ pts Your Answer: Corn and soybeans are 90% transgenic crops. What does this mean? advantageous heritable traits haven been introduced using recombinant DNA technology A transgenic crop has had advantageous traits introduced via recombinant DNA technology.

Question 19^2 / 2^ pts The FDA-approved ATryn used to treat blood clots, was derived from genetically engineered Mice Correct!Correct! Goats Dogs Gorillas Question 20^2 / 4^ pts Your Answer: A gene can be inserted into carrier DNA using enzymes that cut the DNA called __________. This carrier DNA is referred to as a ________. restriction enzyme rDNA Restriction enzymes; vector

Their model of the doubled stranded helix structure of DNA won the Nobel Prize. Question 23^2 / 2^ pts True or False: DNA is responsible for carrying the genetic information within organisms. True Correct!Correct! False Quiz Score: 93.33 out of 100

Question 1^2 / 2^ pts Which of the following statements is correct? Mendel’s work demonstrated that genes are linked to similar genes.

Low altitude Humid environments Question 4^0 / 4^ pts Your Answer: A homozygous long-haired cat is bred with a homozygous short- haired cat. Assuming that the gene for long hair is completely dominant, what are the chances of the F1 offspring being short- haired? 0% 0%; All offspring will be heterozygous long-haired. Question 5^0 / 4^ pts Your Answer: A dog breeder is looking to cross a long-haired female dog with a short-haired male dog. The gene for hair length has incomplete dominance. By crossing the F1 offspring, what percentage of the F2 generation are predicted to be medium-haired?

50%; A 1:2:1 ratio predicts 50% of the offspring to be heterozygotes, or medium- haired. Question 6^0 / 6^ pts Your Answer: Consider 3 genes that assort independently in squirrels. A gene for brown color is dominant (D), a gene for a bushy tail is dominant (B), and a gene for reflux after eating acorns is recessive (a). Use the product law to predict the likelihood of producing a squirrel (from parents that are heterozygous for each trait individually) that is brown, skinny-tailed, but feels ok after eating lots of acorns. 3/64 that feels okay after eating lots of acorns,but brown and bushy tail (3/4) x (1/4) x (3/4) = 9/64 probability of brown, skinny- tailed, and with no reflux.
