Answer: Cells are the basic units of life, and Viruses are non-living infectious particles, much smaller than a cell, and need a living host to reproduce
Explanation:
The answer is B. They do not usually bring precipitation.
High clouds appear in the highest levels of the troposphere. They are most brilliant white due to the ice crystals in this level. Sunlight passes through high clouds most of the time as it's thickness is relatively thin. There are three main types of high clouds: cirrus, cirrostratus, and cirrocumulus. These clouds usually develop on says with weather and lighter winds at the surface, generally these clouds do not produce precipitation except in some cases.
Carbon (C) is an element
Carbon Dioxide (CO2) is a compound
Hydrogen (H) is an element
Sodium Chloride (NaCl) is a compound
A good way to tell whether something is a compound or an element, is that in a compound there is a mixture of different elements. Like in Carbon Dioxide, the symbol is CO2. This shows the carbon (C) and oxygen (O) together. I hope i worded that well enough and this helps :)
When new oceanic crust is made, it spreads out, taking up space. Scientists did not understand how new crust was not increasing the size of Earth.
Answer:
Nitrogen ---- formed due to the transformation of ammonia (NH3)
carbon dioxide and water vapor ----- released into the atmosphere during volcanic eruptions
helium ------ mostly escaped Earth's atmosphere due to it is light mass.
Explanation:
Nitrogen are formed due to the transformation of ammonia (NH3) due to action of beneficial nitrogen, carbon dioxide and water vapor are released into the atmosphere during volcanic eruptions and helium mostly escaped Earth's atmosphere due to it is light mass. Helium has atomic mass i.e. 2 which is second lowest after hydrogen mass so due to its lighter weight it can't be stay in the atmosphere near to earth.
