what is the correct order of the parts of a human body system from the most simplest to the most complex?
jenyasd209 [6]

Answer:

Cells --> Tissues ---> Organs --> systems

Explanation:

There are four levels of organization of life in organisms. These are the cells, tissues, organs and systems.

- Cells

This is the first and simplest level of organization of life. Cell is the smallest unit of body of living organisms. Examples of cells are rod and cone cells in the eyes, nerve cells, red blood cells etc

- Tissues

A tissue is the second level of organization of life. It is a group of similar cells forming a layer in an organism which performs a particular function. Examples of tissues include blood and muscles

- Organs

An organ is the third level of organization of life. It is a group of similar tissues forming a layer which performs a specific function. Examples of organs in the body include skin and eyes

- System

An system is the fourth level of organization of life. It is a group of similar organs which work together to perform specific functions. Examples of systems in the body of animals include nervous and digestive system. The systems then work together to make up the body of an organism.

Thus, the correct order from the most simplest to the most complex is:

Cells --> Tissues ---> Organs --> systems

In "Why Do We Yawn?," the author states that scientists “have
jekas [21]

The author supports the statement by explaining the different theories about yawning, this includes theories and some that are still studied.

The author states that scientists have not yet reached any consensus regarding theories about why humans yawn and argue this claim by explaining the following theories about yawning:

  • In Antiquity: Hippocrates' Yawning Theory focused on the respiratory system by hypothesizing that yawning precedes fever and is a way of removing polluted air from the lungs.
  • In the seventeenth and eighteenth centuries: Most theories focused on the circulatory system. These theories posited that yawning causes an increase in blood pressure, heart rate, and oxygen in the blood.
  • Today: Dr. Robert Provine, in 2005 stated that yawning is associated with changing a state of behavior.
  • Gallup in 2008 proposed that yawning is related to a way of cooling the brain's temperature.
  • In 2011, Dr. Andrew Gallup and Omar Tonsi Eldakar stated that yawning is related to the outside temperature, that is, when the temperature is warm, the body yawns less frequently.

According to the above, it can be inferred that scientists have not reached a consensus on yawning because all have raised different theories to explain its function.

3. What are 6 things the ocean provides for humans?
Veseljchak [2.6K]

Answer:

What are 6 things the ocean provides for humans?

The Ocean produces more oxygen than the Amazones.

The Ocean regulates the Earth climate.

It is an important source of food.

The best holidays are close to the water.

Many jobs are related to sea activities.

The Ocean has therapeutic properties.

Explanation:

It is often thought that rainforests are the primary source of oxygen on the planet, but the truth is that rainforests are only responsible for 28% of the oxygen on earth while oceans are responsible for the 70%. It does not matter how far we live from the sea, from every ten breaths you take seven come from the ocean

In many ways, the sea regulates our climate. It soaks up the heat and transports warm water from the equator to the poles, and cold water from the poles to the tropics.

The ocean is the number one source of protein for more than a billion people. Fish accounts for about 15.7% of the animal protein consumed globally (2).  Although, not everything is fish and seafood.

The ocean is not just home to us ocean lovers, but it is home to the greatest abundance of life on our planet. When you sail across an ocean, you will see dolphins, whales or a turtle popping up to take a breath.

The ocean is a happy-zone! Our temple, our life, our second home, our exhilaration place. It’s where we swim, surf, sail, dive, chillax, and ‘lime’. Family holidays and Sundays often happen on the beach. For sailors, fisherman and islanders, it also is a transport zone.

The FAO estimates (6) on the most recent official statistics indicate that 59.6 million people in the world were engaged in fisheries and aquaculture in 2016. Only at the European Union level, the blue sector represents 3.362.510 of jobs(7), in 9 subsectors: coastal and maritime tourism, Aquaculture, Renewable Energy, Mineral Resources, Biotechnology, Fisheries, Shipbuilding and Ship repair, Offshore Oil and Gas, and Transport. In fact, 90% of the world trade is made by sea

How does the fossil record help scientists understand the process of evolution?
artcher [175]

Answer: Fossil records help provide clues to the history of Earth's organisms. They've have given scientists clues needed to determine a present day organism's ancestry by comparing them with fossils. Fossil records also show that life has evolved from simple to complex; for example, fossils deeper into the ground (older ones) are much more simple than the ones at the top (newer ones), again supporting the idea of evolution. Fossils additionally show us how behaviors have evolved, how long individuals lived, and how features evolved over time.
