Match the following.

1 . adenine a nitrogen base occurring in dna and rna;
2 . deoxyribose first leaf or leaves
3 . guanine a nitrogen base found in dna or rna;
4 . cytosine
5 . dna a giant molecule consisting of the sugar deoxyribose,
6 . cotyledons a nitrogen base found in dna and rna;

a. pairs normally with thymine
b. produced from the seed
c. pairs normally with guanine
d. a five-carbon sugar
e. phosphates and nitrogen bases
f. normally pairs with cytosine

1. Adenine

2. Cotyledons

3. Cytosine

4. DNA

5. Guanine

Explanation:

1. A nitrogen base occuring in DNA and RNA; pairs normally with thymine is Adenine.

According to Watson and Crick, purine bases always pair with pyrimindine bases. Hence, Adenine always pair with Thymine and Guanine always pair with cytosine.

2. First leaf of leaves produced from seed is cotyledons. When it is one, the plant is a monocot, if two, the plant is a dicot.

3. A nitrogen base found in DNA or RNA; pairs normally with guanine is cytosine.

4. A giant molecule consisting of the sugar deoxyribose, phosphates and nitrogen bases is a DNA.

5. A nitrogen base found in DNA and RNA; normally pairs with cytosine is guanine.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
