Cancer is best described as:

organs that may have had a function in an ancient ancestor, but are now nonfunctional

symbiotic relationship(s) that are (+/-)

Which of the following is a heterozygous genotype?

A malignant tumor is:

A written set of choices that leads you to the identification of an organism:

Which blood type (phenotype) is codominant?

If the template strand of DNA reads: 3' TCA CTG ACC TCG 5' then the complimentary mRNA strand reads:

Z= stripes & W = polka dots: An organism that is ZW will have both stripes and polka dots-- this is codominance

XX and XY:

Colorblindness= X-linked recessive. What % chance does a son have of being colorblind if mom is colorblind & dad is not?

Comparative anatomy is evidence for evolution. These structure are best described as homologous.

Multiple interconnected food chains that show various feeding relationships best describes a(n):

DNA is antiparallel: it runs 3' to 5' on one strand and 5' to 3' on the other strand

This pictured gif shows a _____________________.

B= blue, b= yellow: If a blue monster and a yellow monster mate and they have a green monster baby, then...

a symbiotic relationship in which both species benefit (+/+)

Prokaryotes reproduce:

If the P generation is RR x rr, then the F1 generation would be:

The feeding style that describes organisms capable of consuming both plant and animal matter.

Humans have 46 chromosomes- 44 are autosomes, also known as _____________ and 2 are sex chromosome, known as _________.

Food chain= "phytoplankton--> zooplankton--> sea star". If the phytoplankton has 1500 kcals of energy, then....

Using the dichotomous key, organism "B" is a:

This food web illustrates 1 producer, 3 herbivores, and 6 carnivores.

If DNA reads 3' TCA TTT 5', then mRNA would read:

a symbiotic relationship in which one species benefits and the other is unaffected (+/0)

The three major domains are:

The Kingdoms of Life include Plants, Animals, Fungus, Protists, Archaebacteria and Eubacteria.

Meiosis: Sperm production = 4 haploid cells; Egg production= 1 mature ovum (other 3 egg cell [polar bodies] die)

This food web illustrates no less than 8 food chains.

The best food source for the lion (from a caloric intake perspective) would be the goat.

Cancer is best described as:

DNA is semiconservative: each strand contains one original strand and one newly replicated strand.

This pedigree could illustrate an autosomal recessive pathway where generation I-1 and I-2 are both heterozygous.

In the genotype Aa, "A" and "a" represent alleles, alternate forms of a gene.

In a Y-linked trait,

Which organism is most closely related to rabbits and rodents?

If DNA reads 3' TCA TTT 5', then the amino acid sequence would read:

In this food web, the lion acts as a 2^o , 3^o and 4^o consumer, depending on what food chain it is involved in.

Sex chromosomes are also known as gametes, sex cells, reproductive cells, and sperm & egg.

The main source of energy for this food web would be:

Which organism(s) are vertebrates w/ a bony skeleton, & 4 limbs but lack amniotic eggs, hair & 2 post orbital fenestrae?

A chromosomal mutation where chromosomes fail to separate- one of the two in a pair is missing.

embryo --> zygote--> fetus is the proper sequence of human development

Consumers are otherwise known as

gamete (n) + gamete (n) = 2n, where n= haploid set of chromosomes and 2n= diploid set of chromosomes

Transfers amino acids to the ribosome during translation (and has an anticodon to "spell check" the codon):

the reproductive sucess of an individual

Embryos that look very similar in early embryonic development suggests that:

Structures that look similar or have similar functions, but are not closely evolutionarily related.

The role an organism fulfills is its niche. For example, fleas and tick have the niche of being ectoparasites.

B= blue, Y= yellow... so BY= in codominance

Wisdom teeth, nictitating membranes, goosebumps and coccyx (tailbones) are vestigial structures in humans.

Evidence for evolution that is the best:

_________________ are always at the 1st trophic level.

Cytokinesis (in the mitotic cell cycle) in plants versus animal cells:

Transcription occurs in the nucleus and translation occurs in the ribosome.

Anatomically similar structures that were inherited from a common ancestor (but may serve a different function)

A person with blood type O:

During meiosis:

3 mRNA nucleotides = 1 codon and 1 codon codes for an amino acid or command

B= blue, b= yellow: If a blue monster and a yellow monster mate and they have a green monster baby, then...

Importance of G1, S, & G2

Meiosis= sexual reproduction while mitosis = asexual reproduction

The cell cycle for Eukaryotes:

Producers are:

This food web illustrates a ____________, as there are many different species are represented (and no abiotic factors).

mRNA is transcribed from DNA; tRNA translates mRNA into the amino acid sequence; rRNA makes up a ribosome.

If B is dominant & b is recessive in complete dominance, then a cross between two heterozygotes will result in:

If R= red and r = white: the genotype Rr will be phenotypically pink-- this is incomplete dominance

The order of hierarchy of classification is Domain-->Kingdom-->Phylum-->Class--> Order-->Family-->Genus--> species

Mitosis differs from Meiosis in that:

If the template strand of DNA reads: 3' TCA CTG ACC TCG 5' then the complimentary DNA strand reads:

fertilization (sperm + egg) restores the diploid number of chromosomes in a human:

A chromosomal mutation where chromosomes fail to separate- you get 3 instead of two for the pair
