The smallest item in the list would be organelles. Organelles are tiny structures within a cell, that help it to function. Example of organelles are-- nucleus, mitochondria, cell membrane to name a few. Cells are the basic unit of structure and function of all living things, therefore, cells would have to be placed second. They are microscopic. A group of similar cells that work together to perform a specific function, is known as a tissue. Therefore, tissue is next largest. Examples of tissues include, muscle tissue, epithelial tissue, adipose tissue. When different types of tissues work together to perform a function in the body, this group of tissues forms an organ. An example of an organ is the heart. Inside the heart are many types of tissue-- cardiac muscle,nerve, blood, connective, etc. The job it performs is to pump blood. When various organs work together to perform a specific function in the body, this makes up a system. An example is the circulatory system. In this system are many organs that work together. Arteries, veins, capillaries and heart are all part of the circulatory system. Its job is to circulate blood containing nutrients and oxygen to cells and to pick up cellular wastes. All the systems of the body comprise the organism. An organism is a living thing. It can be as tiny as a microbe, or a complex as a human. When referring to a multicellular organism, the correct order from smallest to largest is-- organelle, cell, tissue, organ, system, organism
As true pressure we denote the absolute pressure. <span>
Gauge pressure is the pressure above the ambient pressure </span>(it is zero-referenced against ambient air pressure). Absolute pressure <span> is equal to gauge pressure plus atmospheric pressure.</span>So, according to this the gauge pressure is always less than the absolute pressure.
Answer:
the chlorophyte group contained extensive genetic variability
The Ecological Footprint measures the amount of biologically productive land and sea area an individual, a region, all of humanity, or a human activity that compete for biologically productive space. This includes producing renewable resources, accommodating urban infrastructure and roads, and breaking down or absorbing waste products, particularly carbon dioxide emissions from fossil fuel. The Footprint then can be compared to how much land and sea area is available.
Biologically productive land and sea includes cropland, forest and fishing grounds, and do not include deserts, glaciers and the open ocean.
Current Ecological Footprint Accounts use global hectares as a measurement unit, which makes data and results globally comparable. Calculation methods are standardized so results of various assessments can be compared.
