Question 2 The following chart lists taxonomy classifications for seven organisms. Some have just one classification, while others
have a subclassification. Which four classifications best match the classifications of your fossils? Research the
classifications if you don't know their characteristics.
Classification
Organism 1 Brachiopoda
Organism 2 Mollusca, Gastropoda
Organism 3 Arthropoda, Trilobita
Organism 4 Chordata, Actinopterygii
Organism 5 Pteridophyta
Organismo Nematoda
Organism Ascomycota
Now complete the following table to explain your reasoning for the classification of your fossils.

Arational expression has been simplified below. (x-5) (x+1)/3(x+1) = x-5/3 for what values of x are the two expressions equal

Rease is an enzyme used by plants to break down urea (a nitrogen-containing compound) into carbon dioxide and ammonia. urease urea > > > carbon dioxide and ammonia ammonia is broken down by plants into a nitrogen source plants need to grow. thus, plants could not use urea as a nitrogen source unless it was first converted to ammonia. in soybean plants there are two different kinds of urease, one produced in the seeds and the other produced in the leaves of the plant. three types of soybean plants were used in a set of experiments: normal soybeans and two mutant strains, one lacking the urease in the seeds only (strain 1) and one lacking urease in the leaves only (strain 2). experiment 1 separate areas in a field were planted with normal, strain 1, and strain 2 soybeans. all types of soybeans appeared to grow, flower, and produce seeds equally well. there were no externally detectable differences among the strains. experiment 2 small pieces of plant leaves of equal weight were obtained from each type of soybean plant and separately placed on media in culture dishes. tissue growing in this way will become an unorganized clump of cells referred to as callus. to provide a controlled nitrogen source, half the tissue samples of each type were placed on media containing urea, and the other half of the samples were placed on media containing ammonia. after 30 days, the weight gain for each of the callus samples was determined. results are shown in the table below.

This is a situation in which genes are attached to an organism's sex chromosomes; the sex of an organism influences the expression of a gene.
