The impulse starts at the SA node that has its own contraction rhythm (but can be faster or slower depending on other impulses or hormones). That impulse travels then through the atria and is slowed down by the atrioventricular septum except for a region in the right atrium called AV node where the impulse has continuity. The impulse travels then to the ventricles through the AV bundle. The impulse continues through bundle branches to other fibers: Purkinje fibers. These Purkinje fibers cause then a contraction that goes from the apex of the heart and rapidly through the ventricles.</span>

A. The correct answer is Venus
Carnivores' biological traits aid in their ability to hunt. Wolves and other carnivorous mammals have powerful jaws and large, sharp teeth that enable them to seize and tear apart their food. On the other hand, plant-eating animals typically have large molars that aid in the grinding of leaves and grasses.
Carnivores are the largest animals in the world. The blue whale can grow to be 30 meters (100 feet) long and up to 180 tonnes in weight (200 tons). It eats by gulping down large amounts of water and filtering out microscopic krill organisms, which resemble shrimp. About 40 million of the tiny animals, or 3.6 metric tonnes (4 tonnes), can be consumed daily by blue whales.
The polar bear, which mostly consumes seals, is the largest terrestrial carnivore. Sharp claws are a hunting tool for cats like lions, cougars, and other species. Birds with talons, often known as claws, use them to hunt, including hawks and owls. The curved beaks of many carnivorous birds, known as raptors, are used to break apart their prey.

The three groups of amphibians: Salamanders, Frogs, and Caecilians are different because they look different as adults. Salamanders have tails and they have four weak short limbs that allow them to walk instead of jump. Frogs have fours legs with strong hind legs and no tails. Caecilians have no legs and they are burrowing animals.
