Connecting the Concepts: Waters life supporting properties
The___ of water molecules and the hydrogen bonds between water molecules explain most of waters life supporting properties. The ____ of water molecules to each other helps transport water form the roots to the leaves in plants. When water warms or co

This pedigree traces tongue rolling in a family. Filled in circles and squares represent the ability to roll the tongue. The ability to roll your tongue is controlled by a dominant allele; people with the recessive allele cannot roll their tongue. Id
Can you identify the trophic levels at which these animals feed?
Hi! So I'm stuck on this one question because I don't understand if the hawk would be considered a secondary, tertiary AND quaternary consumer, or would it only be considered a quaternary consumer? Same goes with the shrew and the mockingbi
Summation of postsynaptic potentials at the axon hillock
The figure below shows a single postsynaptic neuron that has synapses with four other neurons via their synaptic terminals. Two of the presynaptic neurons produce EPSPs on the postsynaptic cell (green, E1 and E2), and the other two produce IPSPs (red

A dominant allele, T, codes for the ability to taste the compound pheylthiocarbmide (PTC). People who are homozygous for the recessive allele, t, are unable to taste PTC. In a genetics class of 125 students, 88 students and can taste PTC and 37 canno

Nutrients in food can be divided into six groups: carbohydrates, fats and oils, proteins, vitamins, minerals, and water. All work together to support the body’s energy and functional needs. Match the words in the left column to the appropriate b
If the body created more blood vessels would it also create more nerves? How intertwined are these two systems? Which proceeds which? Do they often interfere with one another or are they nearly step for step?
Can you identify which chordates belong to each clade?
The directions are Drag the labels to the table to indicate which chordates (listed down the side) belong to each clade (listed across the top). Remember that a chordate may belong to more than one clade.
Help please Darwin theory, guppy spots, bioman! :)
1)Below are two histograms showing guppy coloration in two different streams, Stream North and Stream South. Use these histograms to answer the first two questions. Q1. Which spot brightness level is most heavily represented in Stream North?
Answer the following questions about translation elongation in the wild-type and
Wild-type strains of E. coli have a tRNA that carries the amino acid tyrosine and has the anticodon 5′-GUA-3′. This anticodon recognizes the mRNA codon UAC. We can represent this tRNA as GUA-tRNATyr. Suppose you isolated a strain of E. coli in w
