Answer: All of the offspring are brown. The chances of getting a brown deer is 100%.
Explanation: The buck is homozygous dominant, meaning he has two of the brown (B) allele. The doe is white, and since the allele for a white coat is recessive, it has to have two white (b) alleles.
Set up a Punnett square with BB on one side and bb on the other. The results of this are 4 offspring all with the genotype Bb. Because brown (B) is dominant, all of them are brown.
To find the chance of getting a brown deer, take the number of brown deer (4) and divide it by the total number of outcomes (4). This gets you 4/4 or 1. As a percent, that would equal 100%.
Spontaneous generation was a (refuted) theory that some forms of life can arise from inorganic matter.
Louis Pasteur refuted it in a series of experiments, in which he boiled different matter (grape juice, broth) which would kill all the bacteria and let it stay for a long time to see if it would develop life (he also had a control condition in which he let the boiled liquid interact with the outside words, and those would develop bacterial life).
For an organism to be classified in the animal kingdom it is necessary for that organism to be eukaryotic and multicellular. In addition, he must not be able to produce his own food (he must be heterotrophic), and must eat by eating food taken from the environment.
To be classified in the dilo arthropoda, the organism must have an external skeleton, a segmented body and articulated legs.
To be classified in the insect class, the organism must have a separate body in the head, chest and abdomen, have two antennae, two pairs of wings and three pairs of legs.
