Answer:

While all crocodiles, tuataras and most squamates (a clade consisting of snakes, lizards and amphisbaenians) have teeth, all living birds and turtles possess toothless beaks for mouths. Technically called rhamphothecae, their beaks are built from

Answer: Echidnas: With a keen sense of smell, an echidna uses its long, hairless snout to search for food, detect danger and locate other echidnas. Termites are the preferred food, which is why the animal is often called the 'spiny anteater'. After finding food, an echidna catches the prey with its long, sticky tongue

Crocodiles: Crocodiles are mostly nocturnal animals. They are predators and spend most of their time in the water; although they are also known to make journeys of several kilometres over land. ... Crocodiles capture water animals in their jaws with a sideways movement of the muzzle

N76 [4]

Answer:

By designing suitable gene therapies in order to restore target gene expression.

Explanation:

Cystic fibrosis and muscular dystrophy are inherited genetic disorders associated with serious health problems. Cystic fibrosis is caused by mutations in the gene that encodes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein, and it is a condition associated with abnormal production of sticky mucus that leads to problems in the lungs and the digestive systems. On the other hand, muscular dystrophy is produced by mutations in genes localized on the X chromosome such as, for example, the gene 'dystrophin'. Gene therapy is an experimental approach used to compensate abnormal gene function by introducing exogenous genetic material and thus restore their altered protein products. Consequently, personalized gene therapies can be useful to treat inherited disorders such as cystic fibrosis and muscular dystrophy.

Answer:

Covalent bonds form when two atoms share valence electrons,

while Van der Waals forces cause an attraction between nonpolar

molecules

Explanation:

A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.

Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).

Alona [7]

Answer:

C

Explanation:

It is believed that glycolysis – the first phase of cellular respiration in eukaryotic cells- is considered an ancient biochemical process that early organisms utilized to tap the energy required for cell functions. This is because the process does not require oxygen – because early conditions on earth were anoxic before the great oxygenation event.  It is after the great oxygenation event that the Krebs cycle evolved.
