Answer:
Invertebrates can have bilateral or radial symmetry, or they can be asymmetrical. Bilateral symmetry means that the animal is arranged in the same way on both sides. Radial symmetry means the body parts are arranged in a circle around a central point.
it takes place in the eukaryotic and prokaryotic cells.
in eukaryotes cell, it occurs in the matrix of the mitochondrion.
as you consider this, to me the answer is matrix
An atom will usually form either an ionic bond or covalent bond with another atom but not both.
Ionic bonds are the kind of bonds that result when one atom transfers or gives up electrons and another atom receives them and adds them to its own energy shells.
An example is sodium metal and chlorine gas. Sodium gives up two of its electrons and Chlorine receives them and the two elements form an ionic bond to create sodium chloride, a new compound.
Covalent bonds are the kind of bonds formed when two atoms decide to share electrons. No atom gives up any electrons and neither does the other atom receive any. An example is water. An oxygen atom shares two of its electrons with two hydrogen atoms to form a molecule of water (H2O).
According to a new study, spider's fangs are considered to be natural needles that they use for piercing the skeletons of prey and delivering the kiss of a venom. The fangs can also be used as a defense mechanism towards their predator or towards humans.
On the other hand, the crustacean's claws, like the crab claws can be used for protection, as well as for communication, excavating burrows, attracting mates and gathering food.
While the centipedes use their claw to grab their prey and inject venom to kill it or to protect itself from being harmed.
Considering these definitions, we can say the Gerri and Alana are both correct since the spider uses its fangs to inject venom like the centipede and to protect itself like the crustaceans.
