AH my toe sis
The name of the type of cells made during meiosis.
What is a gamete?
This is the shape and structure of a DNA molecule
What is double helix made of nucleotides?
All living things belong to this sphere.
What is the biosphere?
Organisms get their genetic information from...
What is their parents? (one from mom, one from dad!)
This creates variation to drive natural selection and evolution.
What is a mutation?
These are the purposes of mitosis.
What is growth, repair, and maintenance?
This is the end product of translation.
What are proteins?
During this type of feedback loop, a stimulus is reduced and counteracted.
What is a negative feedback loop?
Using the letter A, write down a homozygous recessive, homozygous dominant, and heterozygous genotype.
What is
Homozygous Recessive: aa
Homozygous Dominant: AA
Heterozygous: Aa?
In natural selection, advantageous traits ___________ in a population, and disadvantageous traits _______________ in the population.
What is increase/decrease?
These two processes occur during meiosis to cause variation.
What is crossing over and random assortment?
This molecule's purpose is to carry a copy of genetic information to the ribosome.
What is RNA?
Which sphere is carbon moving from when elodea (aquatic plant) does photosynthesis?
What is the hydrosphere?
Show a cross a heterozygous parent and homozygous dominant parent using the letter T.
See the Board!
This are the four pieces of evidence for evolution.
What is comparative anatomy, embryological homologies, fossil record, and genetic information?
DAILY DOUBLE!!! Explain why we have different types of cells in our body despite having the same DNA in all body cells.
Cell differentiation... although we have the same sequence of DNA in our body cells, different genes turn on and off, which affects the expression of traits.
The structure and sequence of your proteins make up what type of ___________ you have.
What is traits?
This is when humans burn fossil fuels.
What is combustion?
Freckles are a dominant trait. Cross a parent who has a homozygous dominant genotype and a parent who has a homozygous recessive genotype. What is the probability of their offspring having freckles?
What is 100%?
The ability to survive, reproduce, and pass on traits to offspring.
What is fitness?
Write as many differences between meiosis and mitosis as you can! Each one will net you 500 points (:<
Mitosis: One cell division, body cells only, identical cells
Meiosis: Two cell divisions, gametes only, unique cells
This occurs when there are errors in transcription or translation.
What are mutations?
This is an example of a positive feedback loop.
What is blood clotting OR release of oxytocin during childbirth?
If widow's peak hairlines are a trait caused by a dominant allele, what genotypes will express a widow's peak?
What is AA or Aa?
Describe how a change in the environment affects a population.
The environment can change which traits are advantageous or disadvantageous, which in turn affects which traits are able to help organisms survive and reproduce. Over time, the population shifts towards the advantageous traits, and declines in the disadvantageous trait.
