Duchenne's muscular dystrophy is an X-linked inherited disease that caused progressive loss of muscle cells. When the muscle cells die, it will be replaced by fat or connective tissue. Typical microscopic changes that can be found microscopically would be the decreased number of muscle cells and the increased number of fat/connective tissue
Euglena move from one place to another like an animal. When they manufacture their own food, they have to move to such an area where they can receive required amount of sunlight. There are two features on its body that facilitate in its movement. The most important is the flagellum, which is a long whip-like appendage attached to the body. It turns and twists in the water in order to push the body through the water. The other physical feature that plays a vital role in giving a sense of direction to its movement is the eyespot, also located at the anterior of its body. It is a light-sensitive, pigmented organelle which is capable of detecting sunlight. Thus, it orients the movement towards the direction of light, where they can collect sunlight required for making food.The ability to move plays a significant role in vital life processes of Euglena, such as the synthesis of food. Hope that helps ;)

The nucleus is enclosed by a double layered cellular membrane called the nuclear membrane.
<h2>Nucleoplasm</h2>
The nucleus contains a nuclear sap, enclosed by the nuclear envelope, which is known as the nucleoplasm. This holds the nucleoli and suspends the chromatins.
<h2>Nucleolus</h2>
The nucleolus is a sub-organelle present inside the nucleus. It can be observed as a dark spot under the microscope.
Nucleoli are made up of proteins, ribosomal RNA (rRNA), and ribosomal DNA (rDNA).
<h2>Chromatin network</h2>
DNA gets associated with protein molecules to form chromatins.
Chromatins are present in the nucleoplasm.
The
correct answer is a: genetically similar individuals who have been raised in
similar environments.
<span>For
example, monozygotic twins, who share 100% of their DNA that grew up in the
same home have the highest correlation of their IQs (correlation is 0.86). </span>
