Answer:

The structural and functional unit of all living organisms are cells.

Explanation:

Cells are the smallest level of organism such as: humans, animals, plants fungus among many others. At this level of living organisms it is possible to achieve process to keep the organism alive such as: metabolic process, respiration, and so on. Due to it, cells are called the "building blocks of life"

Let's consider an animal, plant or human example:

If you take several cells and join them together, they can form different types of tissues. Those form the building blocks for plant structure or animal organs.

When you join several tissues, you can form an organ. For example: Hearth. If we put together several organs, they can form a whole system. For example: circulatory system.

When you put several systems together, you can get the whole living organism: Circulatory system, digestive system, among others form the human body.

Besides of the above, cells can achieve respiration process, metabolic process among many others. Due to it, they are the structural unit of all loving organisms.

Explain how changes in Earth’s systems affect the growth of life on Earth. Use evidence from the text to support your answer.

andre [41]

Answer:

The earth system usually refers to the different ways in which various physical, chemical as well as the biological processes interacts with one another and it includes the land areas, oceans, atmosphere, minerals and also the different cycles such as carbon, nitrogen, sulfur and so on.

These processes are continuously taking place at, on and below the surface of the earth, maintaining an equilibrium. The life existing on earth is directly dependent on these conditions and on-going processes. When there occurs changes in these conditions, then the lives on earth are affected.

For example, the lives are dependent on the climatic conditions, and when suppose the concentration of green house gases and other toxic elements are increased in an ecosystem, then the temperature will eventually rise, and there reaches a point when it becomes difficult for life to sustain. The organisms will suffer from different diseases.

Thus, the growth of life on earth affects when there occurs changes in the earth's system.

Volume is defined as the amount of mass that an object has? True or false

maria [59]

Answer:

False

Explanation:

Mass and volume are two different quantities. In fact:

- Mass is a scalar quantity representing the "amount of matter" contained in a certain substance. It is measured in kilograms (kg), which is one of the 7 fundamental SI units.

- Volume is a scalar quantity representing the amount of "three-dimensional space" occupied by an object or a substance. It is measured in cubic meters ( $m^3$ ).

Therefore, mass and volume are two different quantities. They are related through another quantity called density, given by:

$d=\frac{m}{V}$

where

m is the mass

V is the volume

So the density of a substance represents the amount of mass contained in a certain volume of the substance.

The four most common chemical elements found in living matter are

Romashka [77]

Explanation:

In all living system we can always find basic elements carbon, oxygen, nitrogen and hydrogen, carbon is the basic building unit contained in living matter. The percentage of carbon in the mass of living matter is 19.0% oxygen and hydrogen are present in almost all organic compound which creates living organisms.
