# Question: What Is The Smallest Unit Of Life?

## Is there anything smaller than DNA?

A gene produce a specific product, usually a protein, or an enzyme that are used for specific action.

The DNA molecules contains thousands of genes which is located inside chromosomes.

Therefore, gene is smaller than DNA..

## What are the 13 levels of organization?

There are 13 levels of organization. In sequence, they are represented as atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, population, community, ecosystem, biome, and biosphere.

## What are the 12 levels of organization?

Levels of organization include atom, molecule, macromolecule, cell, organ, tissue, organ, organ system, organism, population, community, ecosystem, and biosphere.

## What’s faster than a Yoctosecond?

An attosecond is 10^-18 seconds, then there are zeptoseconds which are 10^-21 seconds, and yuctoseconds are 10^-24 seconds.

## Which is the biggest cell?

ovumThe largest cell is ovum in the human body. The ovum also called egg cell is the reproductive cell in the female body. Ovum is 20 times bigger than the sperm cells and has a diameter of about 0.1 mm.

## Is a Yoctosecond faster than light?

RHIC: A future yoctosecond light source? … One yoctosecond is one trillionth of a trillionth of a second (10–24 s) and is comparable to the time it takes light to cross an atomic nucleus. Indeed, the researchers say that such pulses could be used to study the ultrafast processes taking place inside nuclei.

## How small is a Yoctosecond?

A yoctosecond (ys) is a septillionth of a second or 10–24 s*. Yocto comes from the Latin/Greek word octo/οκτώ, meaning “eight”, because it is equal to 1000−8. Yocto is the smallest official SI prefix. A yoctosecond is the shortest lifetime measured, so far.

## How short is a nanosecond?

A nanosecond (ns) is an SI unit of time equal to one billionth of a second, that is, ​1⁄1 000 000 000 of a second, or 10−9 seconds. The term combines the prefix nano- with the basic unit for one-sixtieth of a minute. A nanosecond is equal to 1000 picoseconds or ​1⁄1000 microsecond.

## What’s lower than a millisecond?

Millisecond(One thousandth of a second) Microsecond(One millionth of a second) Nanosecond(One billionth of a second) Picosecond(One trillionth of a second)

## What is the first cell of life?

The first cells consisted of little more than an organic molecule such as RNA inside a lipid membrane. One cell (or group of cells), called the last universal common ancestor (LUCA), gave rise to all subsequent life on Earth. Photosynthesis evolved by 3 billion years ago and released oxygen into the atmosphere.

## Is an atom the smallest unit of life?

Living things are highly organized and structured, following a hierarchy that can be examined on a scale from small to large. The atom is the smallest and most fundamental unit of matter. … All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms.

## Is DNA the smallest unit of life?

Smallest unit of DNA is nucleotide . DNA is the most important molecule of living organisms and universally same in structure.

## What is the largest unit of life?

The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

## How do atoms behave?

Electrons are attracted to any positive charge by their electric force; in an atom, electric forces bind the electrons to the nucleus. … In some respects, the electrons in an atom behave like particles orbiting the nucleus. In others, the electrons behave like waves frozen in position around the nucleus.

## Which is the longest cell in the world?

If talking of human body, largest cell is OVUM or egg cell owing to its diameter however nerve cells are the longest cell. And all over the world the largest and longest cell are the NERVE CELLS Giant Squid and Colossal Squid.

## What is the basic unit of life?

Cells as the Basic Unit of Life. A cell is the smallest unit of a living thing and is the basic building block of all organisms.

## What’s faster than an attosecond?

Q: What is faster than an attosecond? a yoctosecond[1], which is 10^–24 of a second, whereas an attosecond[2] is 10^-18 of a second. … The Planck time is 5.4 x 10^-43 seconds.

## What is smaller than a cell?

Organelles are the substructures (such as mitochondria and chloroplasts) inside cells that perform particular functions. They are therefore smaller than cells. They are therefore larger than cells.

## What is the smallest unit?

zeptosecondWhat is a zeptosecond? A zeptosecond is a trillionth of a billionth of a second. That’s a decimal point followed by 20 zeroes and a 1, and it looks like this: 0.000 000 000 000 000 000 001. The only unit of time shorter than a zeptosecond is a yoctosecond, and Planck time.

## What is the smallest cell of life?

Mycoplasma genitalium, a parasitic bacterium which lives in the primate bladder, waste disposal organs, genital, and respiratory tracts, is thought to be the smallest known organism capable of independent growth and reproduction. With a size of approximately 200 to 300 nm, M.

## What’s faster than a nanosecond?

Picosecond is one trillionth of a second. Nanosecond is one billionth of a second. Microsecond is one millionth of a second. Millisecond is one thousandth of a second.

## What is smaller than a Yoctometer?

Yes, half a yoctometer…..just kidding. Yoctometer is the smallest length unit under the SI international Standard of Units, and represents 1 x 10^-24 meters. The Planck length is smaller at 1.616229(38) x 10^-35 meters and represents the smallest distance of 2 locations.

## Which is the longest cell?

Nerve cells- In the human body, the nerve cell is the longest cell. Nerve cells are also called neurons that are found in the nervous system. They can be up to 3 feet long.

## How long is a jiffy?

Harrison, the time it takes for light to travel one fermi, which is approximately the size of a nucleon. One fermi is 10−15 m, so a jiffy is about 3 × 10−24 seconds. It has also more informally been defined as “one light-foot”, which is equal to approximately one nanosecond.
