Which component of a virus is lacking in a cell

Biology
1 answer:
Mrrafil [7]4 years ago
8 0

The component found in a virus but is absent  in cells is the protein capsid and lipoprotein envelop (for enveloped viruses).  Cells instead have a rigid wall containing peptidoglycan.


Contra wise, there are two major components that are found in cells but are not found in viruses, and these are Ribosomes and mitochondria.

Ribosomes are cell structures  also called the work bench of eukaryotic cells and bacteria  because they are the sites where cell proteins are made.

Mitochondria are organelles found in both eukaryotic and prokaryotic cells. They are also known as the powerhouse of cells because it is here that the process of respiration and energy production takes place.

Jessica is traveling from Chicago, Illinois, to Miami, Florida. Using the map, tell what will happen to the land as she travels
barxatty [35]

Answer:

Option (B)

Explanation:

Chicago and Miami are both the cities in the United States, where Chicago is at a higher elevated area, whereas Miami is located in a low lying areas.

Chicago is located at an elevation of about 180 meter above the sea level, which is comparatively much higher than Miami, as Miami is at the coastal areas whose elevation is only about 2 meter above the sea level.

So, from the map it can be concluded that as Jessica travels from Chicago to Miami, it means that the elevation gradually decreases.

Thus, then correct answer is option (B).

Billions of years ago, How Did earth come to have an oxygen-rich atmosphere ?
Papessa [141]
But roughly 2.45 billion years ago, the isotopic ratio of sulfur transformed, indicating that for the first time oxygen was becoming a significant component of Earth's atmosphere, according to a <span>2000 paper in Science</span>. At roughly the same time (and for eons thereafter), oxidized iron began to appear in ancient soils and bands of iron were deposited on the seafloor, a product of reactions with oxygen in the seawater."What it looks like is that oxygen was first produced somewhere around 2.7 billion to 2.8 billon years ago."It looks as if there's a significant time interval between the appearance of oxygen-producing organisms and the actual oxygenation of the atmosphere."
