Answer:
The two navy officers shown at left are identical twins. ... Identical twins look so similar because identical twins have the same genetic makeup, meaning, the same DNA (same nitrogenous bases). This is because by they are fertilised by the same egg, making them identical.
Explanation:
This is copied so be careful

On number two of the second file, mass is how many atoms there are, while weight is how much he gravitational body the object is on (if any) pulls the object (which is why we weigh nothing in space).
For the first question of the second image, A's answer would be 1,800 g/300cm^3, or 600g/cm^3.
For B, .250g/cm^3 * 200cm^3 is 50g.
For the table: Density is how compact the matter of an object is in a certain amount of space. An example would be that water has a density of 1g/cm^3
Mass is how much matter there IS, for example, a car has more mass than an orange.
Volume is the quantity of 3d space an object has or how "big" it is. For example, a cubed building is the length of one side to the third power
Weight is how much gravity is pulling on an object, and not related to how much stuff an object has other than that, for example, you might weigh 100 kilograms on Earth but none is space, and your matter hasn't changed.
I hope you enjoyed your answer.
Answer:
Mitochondria and chloroplasts are much larger than prokaryotic cells.
Explanation:
According to the Endosymbiotic theory, all the components of eukaryotic cells were once individual prokaryotic cells which were able to function on their own.
The mitochondria was independent enough to perform aerobic respiration and produce energy and the chloroplasts were able to independently convert the energy from the Sun to the chemical energy through the process of photosynthesis.
Later, these cells were engulfed by a single cell and these prokaryotes combined to form a eukaryote that was capable of performing all the functions that the independent cells could.
So, the mitochondria and chloroplasts were able to reproduce on their own, had their own ribosomes and had DNA resembling that of bacteria as they were prokaryotic in nature.
However, mitochondria and chloroplasts could not be larger than the prokaryotic cells to support the endosymbiotic theory.
This is because in order to establish a relationship between the bacteria and the mitochondria and chloroplasts, and for these organelles to have developed from bacteria as their ancestors, they must have sizes comparable to bacteria and other prokaryotes.
At the same time, size in itself is not enough evidence to support origin of these organelles from the bacteria.
The Psychedelic Experience, served as a guide.
<h3>Chromosomes are the thread-like structure found in the nuclei of both animal and plant cells. They are made of protein and one molecule of deoxyribonucleic acid (DNA). Organisms grow by undergoing cell division to produce new cells and replace older, wornout cells. During this cell division, DNA must remain intact and keep its even distributionthroughout the cells. Chromosomes are important to this process to ensure the DNA is accurately replicated.</h3>
