MEIOSIS IS NEEDED BECAUSE...
IT ACTUALLY ISN'T, BUT CAN BE HELPFUL IN SOME ORGANISMS
TO REDUCE THE CHROMOSOME NUMBER BY HALF
SO THAT EVERY CELL IS EXACTLY IDENTICAL
TO MAKE SURE EVERY HUMAN CELL HAS 92 CHROMOSOMES

FOUR UNIDENTICAL GAMETES
FOUR IDENTICAL GAMETES
TWO IDENTICAL GAMETES
TWO UNIDENTICAL GAMETES
A mutation is defined as:
A change in the cell's structure
Anything that changes in an embryo
Any change in the physical features of a human
A change in the DNA sequence
Why are insertion and deletion (frameshift) mutations so harmful?
They change all of the codons from the mutation on down the line, which changes the amino acid sequence
They insert things that an organism doesn't need.
They often delete things that organisms need.
Insertion and deletions are not any more harmful than substitution mutations.
Which type of mutation does the model demonstrate?
Deletion
Substitution
Insertion
Translocation
Which reason explains why nerve cells function differently than muscle cells?
In nerve cells all the genes are expressed.
In muscle cells all the genes are expressed.
In both kinds of cells the same genes are expressed.
In both kinds of cells different genes are expressed.
DNA is considered a "universal" molecule, which allows scientists to insert genes from one animal into another, this is made possible because...
DNA, is not universal, it is in fact radically different between species.
all organisms have a nucleus which stores DNA
all organisms have the same sequence of nucleotides of DNA
all organisms have the same components or nucleotides of DNA
Homologous structures are defined as anatomical structures originating from the same structure in ancestral form. For instance, a bird's wing and the front flippers of a seal are examples of homologous structures. Which of the following does the presence of homologous structures in vertebrates suggest?
All vertebrates developed at the same rate.
All vertebrates developed internally.
All vertebrates evolved from different animals.
All vertebrates have a common ancestor.
Scientists compared the fossil remains of a species that lived 5,000 years ago to members of the same species living today. Scientists concluded that the species changed very little over this period of time. Which statement best accounts for this lack of change?
The environment did not change significantly, and those offspring expressing new characteristics survived their natural enemies.
The environment changed significantly, but the species had no natural enemies for a long period of time.
The environment did not change significantly, and those offspring expressing new characteristics did not survive.
The environment changed significantly, and those offspring without favorable characteristics did not survive.
Scientists can determine relatedness among organisms by comparing partial amino acid sequences. The table shows four partial amino acid sequences from four organisms. Which organism is the LEAST related to the other three organisms?
Organism 1
Organism 2
Organism 3
Organism 4
A student used a microscope to study four members of the phylum Ciliophora. Members of this phylum move when propelled by hundreds of tiny cilia. Although these organisms belong to the same phylum, they are classified as different —
families

The number of light-colored beetles in the population will increase.
There will be more dark-colored beetles than light-colored beetles.
The number of light-colored beetles will decrease.

The image shows part of the humerus bone in different genera of primates. Which statement is best supported by the observable structures of the different humerus
bones?
The primates lived in similar environments
The primates shared a common ancestor.
The primates interbreed with similar organisms in a population.

All the animals to the right of the hagfish would have the common characteristic of -
Positive thigmotropism is a response in plants in which they move and grow toward an object the plant comes into physical contact with, usually curling around the object.
This response of the shoot system benefits the plant by allowing the plant to --
produce more pollen for pollinators
take in more carbon dioxide to convert into glucose
absorb more water to transport to the leaves
reach more sunlight for photosynthesis
Water, sugar, and other important nutrients need to be transported from one part of a plant to another. Which statement correctly describes the interaction of the root and shoot systems during nutrient transport?
The leaves take in water and sugar, which are then transported to the rest of the plant through vascular tissues.
The roots take in water and sugar, which are then transported to the rest of the plant through vascular tissues.
The leaves take in water and the roots produce sugar that are transported to the rest of the plant through vascular tissues.
The roots take in water and the leaves produce sugar that are transported to the rest of the plant through vascular tissues.

The enzyme will be able to bind to more diverse substrates than before.
