In order for life to function, DNA must be used as a blueprint to synthesize proteins. In patients with cystic fibrosis, the mutated CFTR nucleotide has a DNA blueprint that
causes the synthesis of the incorrect protein. According to the DNA segment in Source 4,
Abby and John created the below amino acid sequences. Analyze their sequences and
determine which amino acid sequence is incorrect for the Normal CFTR nucleotide
sequence and explain why it is wrong using your knowledge of protein synthesis.
Abby's Sequence:
Phe Phe Phe Gly Val
John's Sequence:
lle lle Phe Gly Val

Photosynthesis converts solar energy into what type of energy?

Why does it matter if osmosis is put into a “scab” or a “nosebleed? ” where would that leave him?

Use this dichotomous key for insect identification to identify the insect shown. 1. a. insect has one pair of wings. order diptera b. insect has two pairs of wings. go to #2 2. a. front wings thicker in texture than hind wings go to #3. b. front and hind wings are same texture throughout. go to #4 3. a. front wings are short order dermaptera b. front wings cover entire abdomen order coleoptera 4. a. wings with scale on all parts of their area. order lepidoptera b. wings without scales go to #5. 5. a. hind wings smaller than front wings. order ephemeroptera b. front and hind wings nearly equal in size. order odonata the insect pictured is in the order diptera. ephemeroptera. coleoptera. odonata.
