5511 Deck 13 Extra Cards Flashcards
Identify:
The first stage of aerobic cellular respiration
Glycolysis
It takes place in the cytoplasm and breaks down glucose into pyruvate.
List:
The reactants of aerobic cellular respiration.
- Glucose
- Oxygen
The process can be represented by the equation: 6O2 + C6H12O6 → 36 ATP + 6CO2 + 6H2O.
Identify:
The seven traits Mendel tracked in pea plants.
- Flower color (purple or white)
- Flower position (axil or terminal)
- Pod color (yellow or green)
- Pod shape (inflated or constricted)
- Seed color (yellow or green)
- Seed shape (round or wrinkled)
- Stem length (long or short)
List:
The two main types of genes.
- Structural genes
- Regulatory genes
Define:
Phenotype
The observable traits of a particular organism.
Explain:
The purpose of a Punnett square.
Genetic tool used to determine the genotype and phenotype of offspring from two particular parents.
Define:
A genome
The complete set of genetic information in an organism.
List:
The organs of the male reproductive system.
- Scrotum
- Testes
- Spermatic ducts
- Sex glands
- Penis
These organs produce sperm, the male gamete.
List:
The organs of the female reproductive system.
- Ovaries
- Fallopian tubes
- Uterus
- Vagina
- Vulva
These organs are involved in the production and transportation of female gametes and support offspring development.
Define:
Population genetics
The study of genetic variation within a population.
This field examines how genetic variation contributes to evolution.
Who proposed the theory of acquired characteristics?
Jean-Baptiste Lamarck
This theory suggests that traits acquired during an organism’s lifetime can be passed to offspring.
Explain:
What does the theory of acquired characteristics imply about traits?
Traits acquired during life can be inherited.
An example is the giraffe stretching its neck to reach higher leaves.
Describe:
The key experiment August Weismann conducted.
He cut off the tails of mice over several generations.
This experiment aimed to disprove Lamarck’s theory by showing that acquired traits do not affect future generations.
Explain:
The primary difference between Lamarck’s and Darwin’s theories?
Lamarck believed the need for a trait drives evolution, while Darwin argued that evolution occurs through selective pressure on preexisting traits.
This distinction highlights the mechanisms of evolution proposed by each scientist.
Which theory of evolution is more widely accepted today?
Darwin’s theory of evolution.
It is considered the principle governing population genetics.
List:
The five steps of the natural selection process.
- Unique characteristics in every member.
- Overproduction of offspring.
- Variation in lifespan due to hardships.
- Competition for limited resources.
- Favorable genetic traits are passed on.
Mention:
An example of natural selection involving finches.
Darwin’s finches in the Galapagos Islands, which have unique beak sizes and shapes adapted to their feeding habits.
Mention:
A key takeaway from Darwin’s quote on survival.
It’s not the strongest or most intelligent species that survive, but those most adaptable to change.
