A punnet square. The genotype of one parent is written across the top and the genotype of the other parent is written down the side.

The genotypes of the offspring (in this case BB or Bb), are filled in by combining the genes of the parents.

∙ 13y agoA Punnet square is used to show the possible gene combinations.
The alleles of one parent are written across the top, and the alleles of the other parent are written lengthwise along the side.
Example 1:
Parent with Tt on horizontal axis, parent with TT on vertical axis :
T

Results in the following possibilities TT, TT, Tt, Tt
Example 2:

The bone that runs across the top of the chest between the shoulders?
The clavicle, or collarbone, is the bone that runs across the chest, between the shoulders.
What observation of species distribution across earth support the theory of common descent?
One can see similarities in organisms that are found in close proximity, but each population has adaptations that suit the organisms to their particular habitat.
How is cytochrome c used biochemical evidence for evolution?
This electron shuttle is highly conserved across many species and jumps across taxa with little change in composition, thus providing evidence for the common ancestry of many organisms.
What is the role of slime molds in the environment?
We benefit from studying them. It has been shown that slime molds respond to certain chemicals in the same way humans do. As well, they are very useful in studying how cells communicate. The most interesting way we benfit is their application to engineering. Slime molds build efficient networks between food sources. If one lays out oatmeal flakes so that it resembles the layout of cities across the landscape, the slime molds will construct the most efficient pathways between the flakes. This can then be used to build the most efficient transportation routes between the cities. (This was done by engineers in Japan.)

Does seroquel interact with lovastatin?
I've read 2 PIL's on Lovastatin which list possible drug interactions and did not come across this combination but it would be best to phone your local pharmacist before commencing this combination.

Are there some organisms that occur everywhere?
Certain types of species live across the globe
How is the voltage drop across each resistance of series combination related to the correspoding resistance?
The voltage across each series component is proportional to its resistance, and their sum is equal to the voltage between the ends of the complete series string.

What is a spectrum of life?
The spectrum of life is a range, or continuum, of life forms across species. It goes from single-celled organisms to highly complex organisms like humans.
Do unicellular organisms use energy for everything?
Unicellular organisms do not use energy for everything. For instance, diffusion across the cell membrane of the organism does not require the use of energy.
