Mutation. A mistake made while DNA copies which causes changes in DNA
Answer:
<u><em>All of the above.</em></u>
Explanation:
1. Their watertight skin minimizes moistures loss: <em>Reptiles have a reputation that they are “slimy” when we touch and hold them; however, they have dry skin, which has even fewer glands than mammals or amphibians. The main special feature of their skin is that the epidermis is heavily keratinized with a layer, which also prevents water loss.</em>
2. Amphibians must lay eggs in water or in moist soil to reduce moisture loss: <em>Because amphibian eggs don't have an amnion, the eggs would dry out if they were laid on the land, so amphibians lay their eggs in water.</em>
3. Reptile egg shells are harder than amphibians' eggs: <em>Reptile eggs are coated with a leathery or brittle coating, and the animals that hatch from them are miniature versions of the full-sized animal parent. In contrast, amphibian eggs are transparent and jelly-like. The animals that hatch from them still must go through metamorphosis.</em>

Answer:
Sample Response: The first stage of cellular respiration occurs in the cytoplasm. This is where glucose is broken down into smaller molecules. A small amount of energy is also released. The second stage occurs in the mitochondrion. This is where the small molecules combine with oxygen to produce water, carbon dioxide, and a large amount of energy.
Explanation:
The DNA replication products visualized during the sanger method of DNA sequencing are observed in which nucleotides are added.
Sanger sequencing is based on the process of DNA replication. A scientist creates a copy of his DNA strand. Then observe which nucleotides have been added. This way you can see the sequence of nucleotides. A laser excites the fluorescent labels in each band and a computer detects the resulting light.
Sanger sequencing produces extension products of various lengths ending in dideoxynucleotides at the 3' ends. Extension products are separated by capillary electrophoresis or CE. Molecules are injected by an electric current into a long glass capillary filled with gel polymer. Selective incorporation of chain-terminating dideoxynucleotides by DNA polymerases during in vitro DNA replication.
