Answer:

Sea floor spreading-> <u><em>Oceanic ridge and Magma pushing two plates apart</em></u>

Continental drift-> <u><em>Concept of pangaea and Oceanic plates sliding under continental crust</em></u>

Explanation:

Due to the divergent plate movement, the magma come out to the surface, forming the mid oceanic ridge and this separation of plates on the sea floor is known as the sea floor spreading. The magma here pushes the two plates to move apart because of the convection current that generates in the mantle. One example of mid oceanic ridge is the Mid-Atlantic Ridge.

  Continental drift refers to the slow and gradual movement of the lithospheric plates over the viscous asthenosphere layer. This motion of continents takes place because of the plate tectonic movement. Due to this plate motion, the denser plate gets subducts beneath the less denser plates. For example, the oceanic crust when collides with a continental crust, it gets subducted because of its higher density. The great supercontinent "pangaea" also formed and separated due to this plate motion.

As a metal, lithium will lose electrons to have a ful valence shell. How manyvalence electrons will it lose to have full valence
Free_Kalibri [48]

Answer:

It will lose 1 electron

Its charge will be 1+, or simply (+)

Explanation:

Lithium it's located in the group one of the periodic table, the Alkali, and by rule, all Alkali are always gonna loose one electron during a chemical reaction to form a positive ion.

The charge is explained by the fact that, if lithium looses one electron, then it wi have less number of electrons than protons, meaning that, if there's a higher number of protons (positive charge), then the charge will be positive. And since the atom loosed one electron then its charge will be 1+

For example, during a chemical reaction calcium is always gonna loose 2 electrons, so its charge's gonna be Ca2+

Archaea bacteria are different from eubacteria largely by​
telo118 [61]

Answer:

B)Genome

Explanation:

Archaea (Archaea) are single-celled microorganisms. Like bacteria, archaea lack a nucleus and are therefore prokaryotic. However, the differences at the molecular level between archaea and bacteria are so fundamental that they are classified into different groups. In fact, these differences are greater than there are, for example, between a plant and an animal. <u>Currently, archaea are considered to be </u><u>phylogenetically</u><u> closer to eukaryotes than to bacteria.</u>

Eubacteria are also known as "true bacteria", they are microscopic organisms that have prokaryotic cells. Because of their prokaryotic cells, they have a rigid cell wall, but they don't have mitochondria or other large organelles; They only have one chromosome, which is not found in the nucleus. Most of them reproduce asexually
