The periodic table is arranged in alphabetical order. The periodic table is arranged in order of increasing atomic numbers.
Properties of elements can be predicted from their placement on teh table. A horizontal row is called a period.
How Pollution Affects:
The air: it can clog cities with smog, making it hard to breathe. This can also mess with rainfall, because raindrops are water droplets that form around tiny particles of dust or smoke, the latter of which creates acid rain.
The land: Acid rain can rain down onto plants and animals, giving them chemical burns and stripping trees of leaves and bark, leaving decaying organic matter behind.
The water: Pollution in the water can cause the pH (acidity or basicness) of the water to change. A lot of organisms can't survive too much swing in either direction of the pH scale, so they will all start to die, except for a few outliers that can handle it, who's population explodes and completely take over the aquatic ecosystem.
Answer: Cellular respiration and Active transport
Explanation: In process of glycolysis, glucose is broken down into pyruvate which ultimately generates ATP and provides energy. Glucose shortage will affect this cellular process.
In Active transport, ATP is required to transport across the membrane which is provided by glucose. So glucose shortage will affect active transport.
Answer:
C. denitrifying bacteria
Explanation:
Nitrogen cycle consists of series of processes that add and remove nitrogen from the soil and atmosphere. There are several ways in which nitrogen can be added to the atmosphere including nitrification, ammonification, lightning etc.
Certain bacteria are responsible for the conversion of nitrogen from one compound form to another. In a process called DENITRIFICATION, nitrate (NO3-), which is the usable form of nitrogen by plants, is converted back to atmospheric nitrogen (N2) with the help of a bacteria called DENITRIFYING BACTERIA e.g Pseudomonas etc.
Answer:
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body
