Cetaceans (whales, dolphins, and porpoises) are all Mammals. Whales usually are larger and slower in the water. Porpoises normally do not have a pronounced beak as a dolphin would. Dolphins have a curved dorsal fin. Dolphins and Porpoises are extremely intelligent. They are warm-blooded. All dolphins are whales, but not all whales are dolphins. Different animals live in different areas. Killer whales are adapted to colder areas, and they stay in the colder water. Bottlenose dolphins are best suited for warmer areas such as the Atlantic Ocean, so they will have less body fat or flubber because they live in a warmer climate. The Killer Whale will need more body fat because of the colder temperatures. They have smooth bodies to help them swim. They have tiny hairs, but as they age, the hair disappears. They can stay underwater longer based on their breathing and extract oxygen from water; they make super high pitch noises that Bounce off objects in the water Back towards the Dolphins to help determine the location; this is called Echolocation.

dna is synthesized through a process known as _____.
Dna is synthesized through a process known as DNA Replication.
DNA is synthesized through a process known as - DNA replication or semiconservative replication.
DNA replicationsynthesis of new DNA. a double-stranded DNA molecule is copied to produce two identical DNA molecules.is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information or DNA.the replication takes place in the following steps:step 1in the nucleus of the cell the DNA double helix separates after that an enzyme named DNA helicase attaches to the DNA molecule and moves along the molecule and 'unzips' the two strands of DNA
Step 2since nucleotides are floating in the nucleus that means there are A, G, T and C's floating around also. these are bases that form hydrogen bonds with the bases of DNA strands.
Step 3
the enzyme they call DNA polymerase catalyzes the formation of the sugar-phosphate units at the sides of the helix and connects one base pair to the next one
Thus, DNA is synthesized through a process known as - DNA replication or semiconservative replication.

Compare morphological and bio-
chemical evidence supporting
evolution.
The morphological evidence which is shown in fossils to modern animals supports evolution because some dinosaurs, for instance, had feathers and we can obviously see that trait today in birds. The biochemical evidence, which comes in the form of DNA comparison and amino acid similarities, shows that we related closely to monkeys and pigs, which suggests that we have close ancestors to these animals.
Morphological evidence: Physical structures and traits indicate evolutionary relationships.
Biochemical evidence: Genetic and molecular similarities indicate evolutionary relationships.
Evolution is supported by morphological evidence. Scientists can establish evolutionary links by analysing species' anatomy. Homologous structures, which have a common origin but diverse functions, reflect a shared lineage. Comparative examinations of bone structure, limb arrangement, or body plans can reveal evolutionary links.
Biochemical data emphasises genetic and molecular similarities between organisms. Scientists may compare DNA, protein, and other substances at the molecular level. Common ancestry and evolution explain these commonalities. Comparing genetic sequences can show how closely related species are and when they evolved from a common ancestor.

Kinetic energy is described as
Question 1 options:
Decreasing energy
Stored energy
Elastic
Movement
Answer:
elastic
Explanation:
The kinetic energy of a body can be decreased in two cases: When it is stored in the form of potential, for example: elastic or gravitational energy. Or when there are dissipative forces capable of transforming it into other forms of energy, as does the friction force. Which transforms kinetic energy into thermal energy.

Making changes to the secondary structure of hair has a different outcome than making changes to its tertiary or quaternary structure. How does this outcome differ
The outcome differs in the way that the protein folds itself at each level. The changes in the way that it folds lead to:
modifications in the function, shape or in the combination with other proteins.
Protein has different levels of structure. Each of them is related to how the amino acids and other molecules interact with each other. Hair is made of proteins, so if one of the structures is affected, the hair is too.
Let's analyse what happens in each level of structure:
In the case of the primary structure, which is the sequence of amino acids, the modification will give a non-functional protein that will not fold into the following structural level. So, there won't be new hair.For the secondary structure, a modification here can lead to a different folding. In other words, it can change from an α helix to a β pleated sheet or the other way round. This will give a different shape to the hair, like curly or straight.A modification in the tertiary structure modifies the interaction of the R groups in the protein, so the three-dimensional structure that this interaction gives will change, giving a different type of hair.Lastly, if we modify the quaternary structure, the protein won't interact with some proteins, but it may interact with others.
In conclusion, the modification of the secondary structure changes the interaction between the elements of the protein giving hair with different shapes.

As the troponin changes shape (due to binding calcium), it moves the ______ molecule to which it is attached, thus exposing the active sites on the G-actin molecules.
As the troponin changes shape (due to binding calcium), it moves the tropomysin molecule to which it is attached.
Once calcium binds to troponin and causes it to change it shape, it removes the tropomysin away from the binding site therefore effectively exposing the myosin binding sites.
This occurs during muscle contraction (movement) in the skeletal muscles.
