The correct answer is D. Pluto

Explanation

According to the characteristics presented for the celestial bodies, such as the impossibility of cleaning its orbit by its small size and a rock surface without rings, the one that best suits these characteristics is Pluto. This can be explained as in 2006 Pluto was claimed to be a dwarf planet, which means it shares similarities with other planets but due to its size it does clear objects from its orbit and therefore it is not a planet. Also, Pluto is composed of rocks and ice, but different from other bodies such as Saturn it does not have rings. So, the correct answer is D. Pluto.

Determine the maximum number of electrons in the 2f designation
sergejj [24]
Google said

How many electrons fit in each shell around an atom?

The maximum number of electrons that can occupy a specific energy level can be found using the following formula:

Electron Capacity = 2n2

The variable n represents the Principal Quantum Number, the number of the energy level in question.

Energy Level
(Principal Quantum Number) Shell Letter Electron Capacity
1 K 2
2 L 8
3 M 18
4 N 32
5 O 50
6 P 72
Keep in mind that an energy level need not be completely filled before electrons begin to fill the next level. You should always use the Periodic Table of Elements to check an element's electron configuration table if you need to know exactly how many electrons are in each level.

An ion with a -2 charge has? A) one missing protein B) two missing protons c) two missing electrons D) two extra electrons
Andreyy89

Answer:

D.

Explanation:

It would not be gain because it would say +6 instead of -2. Having a -2 charge means it wants to loose 2 electrons so it can form a full shell of 8 electrons. It wants to be inert (stable).

- Hope that helps! Please let me know if you need further explanation.

Cytoplasm is a mixture of what two things?
alexira [117]

In cell biology, the cytoplasm is the material or protoplasm within a living cell, excluding the cell nucleus. It comprises cytosol (the gel-like substance enclosed within the cell membrane) and the organelles – the cell's internal sub-structures. All of the contents of the cells of prokaryote organisms (such as bacteria, which lack a cell nucleus) are contained within the cytoplasm. Within the cells of eukaryote organisms the contents of the cell nucleus are separated from the cytoplasm, and are then called thenucleoplasm. The cytoplasm is about 80% water and usually colorless.[1]

It is within the cytoplasm that most cellular activities occur, such as many metabolic pathways including glycolysis, and processes such as cell division. The concentrated inner area is called the endoplasm and the outer layer is called the cell cortex or theectoplasm.

Movement of calcium ions in and out of the cytoplasm is a signaling activity for metabolic processes.[2]

In plants, movement of the cytoplasm around vacuoles is known as cytoplasmic streaming.
