There are 4 unknown samples that you need to identify based on your understanding of this unit. These samples include: A nucleic acid, a lipid, an enzyme and an amino acid. Here are the test results: *Nitrogen is present in all test tubes except # 1. *Hydrolysis occurs in all except #2. *Sulfur is absent in all samples except #3. *Phosphate is present in sample #4 WHAT ARE THE CONTENTS OF EACH TEST TUBE? EXPLAIN YOUR REASONING. *

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.

not always but somethings can be reproduced in a laboratory.
