This is the survival reason some animals become INACTIVE and hibernate in cold seasons.
What is to reduce their need for food?
100
When the process of mitosis is complete, each daughter cell or the two new cells has the________ number of chromosomes as the Parent cell.
What is the SAME number of chromosomes?
100
These are forms of a gene, we get one from mom and one from dad and they are represented by a pair of letters.
What are ALLELES?
100
He was an Austrian monk whose work with pea plants helped him come up with a theory of heredity & is known as the Father of Genetics.
Who is Gregor Mendel?
100
When an egg and sperm form an embryo, the offspring that is formed will have genetic traits that are:
What is traits passed on from two parents?
200
Scientists have observed that, even within the same nest, some young birds call louder than others. The behavior of a louder cry helps to ensure the young bird's survival by:
What is Parents respond by giving more food?
200
During this stage of the Cell Cycle the cell spend most of its time maturing and developing.
What is INTERPHASE?
200
It is known as the Physical or visible characteristics or traits that are expressed in organism like hair color, height, ect.
What is Phenotype?
200
During natural selection, a peacock with larger, brighter plumage will increase its odds of survival among its species. Although its __________ is the same as other peacocks, its __________ is favored during natural selection.
What is genotype, phenotype?
200
In peas, Tall plants are dominant and short plants are recessive. A tall plant (Tt) is crossed with a short plant (tt). PREDICT the PROBABILITY that they will produce an offspring with the genotype Tt. DRAW & FILL IN a Punnett square for this monhybrid cross.
What is 50% probability will have the Tt genotype?
300
A population of blackbirds in Scandinavia has evolved to migrate to warmer climates in the winter. Evolution has occurred in this population through a:
What is Behavioral adaptation?
300
Correctly Name and DRAW the diagram that represents the second phase of Mitosis.
What is Metaphase where the Chromosomes are lined up in the middle or center of the cell.
300
It is known as a combination of a pair of Alleles (letters). They may be the Same (T T) homozygous or they may be different (T t) heterozygous/hybrid and it CODES for the phenotype which is the genetic information that is passed from parent to offspring.
What is Genotype?
300
Huntington's disease is a genetic disorder that causes the breakdown of brain tissue starting during middle age. Huntington's is inherited by anyone carrying a dominant allele. This genotype will be LEAST likely to have Huntington's disease. Draw a Punnett Square to find out genotype where H:has disease, h: no disease
What is hh?
300
List all the possible genotypes of the offspring from the following monohybrid cross: Aa x aa DRAW & FILL In Punnett square :)
What are Aa and aa genotypes?
400
A fever is a response to a disease-causing agent infecting the body. Raising one's body temperature changes the shape of enzymes in the agent so it cannot reproduce. This type of adaptation best describes the fever.
What is acquired adaptation?
400
These are all the phases in Mitosis in the correct sequence/order.
What is Prophase, Metaphase, Anaphase, & Telophase?
400
This type of genotype is also known as a Purebred because it has the SAME or IDENTICAL pair of Alleles. The genotype can have either a Dominant pair of alleles or Recessive pair of alleles. Give examples of dominant and recessive forms of gentotypes :)
What is a Homozygous Genotype: BB=dominant bb=recessive?
400
In Mendel's observations while working with pea plants, he found that the Tall plants that were crossed with SHORT plants CAUSED the Short plants to disappear because the Tall plant dominated or covered up the short plants. He called the short form that disappeared the ______factor.
What is the Recessive factor?
400
List all the possible genotypes of the offspring and the PROBABILITIES for each of the offspring from the following monohybrid cross: Gg x Gg DRAW & FILL In Punnett square :)
What are GG 25%, Gg 50%, gg 25% probabilities.
500
Darwin observed that a large sea bird on the Galapagos Islands, called a cormorant, could not fly, but the same bird on the mainland could. His theory was that __________.
What is the birds on the islands did not need to fly in order to survive?
500
During Anaphase of mitosis, THESE structures in the cell are responsible for moving the chromosomes & split them at the Centromere and the single chromatid strands are pulled apart to opposite ends of the cells.
What are Spindle Fibers?
500
This type of genotype is also known as a hybrid because it has a DIFFERENT pair of Alleles. Give an example of this type :)
What is a HETEROZYGOUS Genotype? Hh, or Tt, or Bb, etc
500
A widow's peak (W) is dominant to a straight hairline (w). Out of four children with the same parents, only one has a straight hairline. If both parents have widow's peaks, these are the genotypes of the parents. Draw and Fill in a Punnett square to help you :)
What genotypes Ww and Ww?
500
Trait: flower color where P=dominant & p=recessive Cross a HETEROZYGOUS pink flower with a white flower and list ALL possible GENOTYPES with their corresponding PHENOTYPES and PROBABILITIES for each genotype. DRAW & FILL In Punnett square :)
What are Pp= pink flowers 50% & pp=white flowers 50%?
