No they don't
For example humans. Technically humans are place below a wild predators such as sharks in trophic levels.
But the fact is we can eat sharks. So , organisms don't always stay in the same level
The correct answer is option C, that is, the presence of the nuclear membrane.
Cyanobacteria is a phylum of bacteria that attain their energy via the process of photosynthesis, and are the only photosynthetic prokaryotes possessing the tendency to generate oxygen. As a prokaryote, they are devoid of the nuclear membrane.
Euglena refers to a single cell flagellate eukaryote. It comes under the class Euglenoidea. The species of Euglena are witnessed in salt water and in freshwater. Being a eukaryote, they possess nuclear membrane.
Answer:
The provided question is incomplete as there is no option available however the generalized answer would be -
The correct answer would be - For treating the global symptoms related to the allergies, it is known as that the inhaled nasal steroids are far more effective than oral medications.
Explanation:
Nasal steroids are the steroids that relieve congestion problems by decreasing the inflammation in the nose of an individual. These are then inhaled by the nose which directly sprays into nasal passages.
In comparatively the oral steroids take time to show their impact on the individual and even the impact is considered not as effective as the inhaled nasal sprays.
Thus, the correct answer is - For treating the global symptoms related to the allergies, it is known that inhaled nasal steroids are far more effective than oral medications.
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
All eukaryote cells lack a nucleus
