Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy
Answer:
the phyiscal appearance of your genes is called
<h2>
<em><u>PHENOTYPE</u></em></h2>
Answer:
a) The expected phenotype of the F1 plants is 100% RrBb, red kernels.
b) The expected phenotypic classes in the F2 are: 9:3:3:1
9/16 R-B-, 3/16 rrB-, 3/16 R-bb, 1/16 rrbb
Proportions 9:6:1.
9/16 Red kernel (R-B-), 6/16 Brown kernel (rrB- + R-bb), 1/16 White kernel (rrbb)
Explanation:

Numerous catabolic operons have their transcription controlled by glucose. The three enzymes needed for conversion are encoded by the operon's five structural genes.
<h3>How many genes are there in an operon?</h3>
Operons have a transcription promoter at the beginning, two to twelve genes on average, and a transcription terminator at the conclusion (Zheng et al. 2002; Lawrence 2003).
<h3>Yes, there is just one promoter for operons.</h3>
An operon is a group of genes that all use the same transcriptional promoter. Every operon contains regulatory DNA sequences that act as binding sites for regulatory proteins that either promote or inhibit transcription.
<h3>The promoter is a 3 or a 5?</h3>
An area of DNA known as a promoter is where RNA polymerase starts to transcribe a gene. Promoter sequences are often found directly in the genome.
