Ecology
This is the reason it is difficult to get rid of invasive species in their new ecosystem
No natural predator
One difference between meiosis and mitosis are these ending products.
Mitosis: 2 identical daughter cells
Meiosis: 4 genetically different daughter cells
Membrane-bound organelles are only found in this type of cell
Eukaryotes
Polymer
In RNA adenine pairs with this nucleotide through hydrogen bonds.
Uracil
Tadpoles grown in ponds with high densities of tadpoles have lower survival and growth rates than tadpoles grown in ponds with lower densities of tadpoles. This interaction between tadpoles grown in high-tadpole-density ponds would most likely cause the decreased survival and growth rates.
Competition
In mitosis, the last two steps needed to produce two identical daughter cells are this
Telophase and Cytokinesis
Mitochondria supports cell movement by producing this
ATP
Enzymes are classified as this type of macromolecule
Protein
DNA is transcribed into mRNA and is then translated here in the cell
Ribosomes
In the food chain, herbivores are called this
Primary Consumer
The chromosomes line up at the equator of the spindle in their most tightly condensed form in this part of mitosis
Metaphase
The cell would be unable to perform this activity if a mutation caused the golgi apparatus to stop functioning
Packaging proteins for transport out of the cell
This macromolecule is a polar molecule made of repeating units of sugar bonded to a phosphate and a nitrogenous base
Nucleic acids
Incomplete chromosome separation leads to gametes with an abnormal number of chromosomes describes this genetic disorder.
Nondisjunction
The difference between primary and secondary succession
Primary starts with rocks, secondary starts with soil
This genetic event occurs in prophase 1 of meiosis and creates genetic variation.
Crossing over
This is the function of proteins embedded in the plasma membrane
Selectively allow particles in and out of the cell
This macromolecule is a main component of plasma membranes
Lipid
A scientist wants to make a change to a genetic code that will lead to the removal of one amino acid from the sequence of a protein. This is what he should remove to avoid mutations.
Three nucleotides
The 10% rule in the food pyramid says the other 90% is lost as this
Heat
This is what you would see in a cell during anaphase.
The spindle fibers, attached to the two sister chromatids of each chromosome, contract and separate as the chromosomes move to opposite poles of the cell.
Exocytosis uses these to transport material out of the cell
Vesicles
This is why most biological macromolecules contain carbon
Carbon can share electrons with up to four different atoms and form three types of bonding patterns.
This is how cloning is different from selective breeding
Clone offspring are genetically identical to their parents
