Answer:
Cell cycle.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.
The regular sequence of growth and division that cells undergo is called the cell cycle. This cycle makes it possible for the cells found in living organisms to divide and produce new cells.
Basically, there are four (4) phases of the cell cycle and these are;
I. Prophase.
II. Metaphase.
III. Anaphase.
IV. Telophase.
From what i can gather it looks like d
<span> mass of glucose = 0.055 *165 = 9.075 g
vol of methyl alc = 0.185 * 1.87 = 0.346 L = 346 ml
% NaCl ( m/v ) = mass NaCl * 100/ vol of soln
or Vol of Soln = mass NaCl / % NaCl (m/v)
= 32.1 * 100 / 6 = 535 ml the total vol of soln</span>
-58 °C
The melting point is the same as the freezing point.
Answer:
1s² 2s² 2p³
Nitrogen
Explanation:
Excited state configuration: 1s² 2s² 2p² 3s¹
Unknown:
Ground state configuration = ?
Element symbol = ?
Solution:
Let us start by understanding what a ground state configuration entails:
A ground state configuration shows the lowest allowed energy levels of an atom. The excited state denotes when electrons have moved to higher energy levels away from their ground state.
The superscript in the configuration depicts the number of electrons in each of the sublevels.
We can use this number to identify the atom we are dealing with:
Total number of electrons = 2 + 2 + 2 + 1 = 7 electrons
The element with 7 electrons on the periodic table is Nitrogen.
Now, the ground state configuration:
In writing the electronic configuration of an atom, certain rules must be complied with.
- Aufbau's principle states that the sublevels with lower energies are filled up before those with higher energies. The order of filling is:
1s 2s 2p 3s 3p 4s etc
To fill the s-orbital = 2 electrons
p-orbital = 6 electrons
The outermost shell electrons are usually the ones excited.
Now, the 3s¹ shell is an excited one taking 1 electron from the second energy level;
The ground state configuration is 1s² 2s² 2p³
