This can happen because you have recessive and dominant characteristics passed down. So you can get a totally different chromosome that doesn't come from your parents because your grandparents may have had it or great grand parents, the line keeps going .
These statements are both true. However, tuna are warm blooded and all other fish (but mackerel shark) are cold blooded. There are many fish that swim in both the Atlantic and Mediterranean. Therefore the answer must be B.
Answer:
A. Hydrogen bonds
Explanation:
A. Hydrogen bonds causes water molecules to stick together in liquid water.
Answer:
Energy cannot be destroyed but moves from one state to another
Explanation:
In an ecosystem the dependence on energy is one of the main driving forces. Most animals and plants are always growing, changing location and moving and all these functions require energy. The energy after transformation from the sun, is referred to as biomass and the transfer of energy from one organism to another is called a food web.
The answer is:
D. Matter and energy can change forms and locations in ecosystems.
Temperature inversion or thermal inversion is a phenomenon during which the temperature increase when there is an increase in the altitude. It is an uncommon process that happens in the troposphere-the layer of atmosphere closest to the earth.
When there is an increase in temperature with altitude, that warm air acts as a blockage for the cool air near the surface of the earth. So this is just opposite to the normal behavior of the air, where it becomes cooler with an increase in altitude.
So how air circulation behaves during inversion?
So as we said that the cool air nearer to the earth will be blocked by a layer of warm air. This blockage will hinder the circulation of air upwards from the lower layers. Let’s see how:
• As we know that, warm air is less dense and more buyout than cool air and normally less dense warm air is close to the earth and cool air is in above layers. But when the process is reversed, this warm air acts like a blanket for the proper circulation of air. Due to this, many environmental pollutants which normally leave the earth during air circulation get trapped in our air.
• The trapped environmental pollutants like nitrogen oxides and hydrocarbons get convert into harmful ozone that ultimately deteriorates the quality of air and causes problems like smog.
• The improper air circulation also causes suspension of the harmful gases near the earth instead of allowing them to leave the earth atmosphere. This ultimately causes air pollution.
• When smoke will not rise, carbon dioxide will be build up in the atmosphere; this will cause greenhouse effect and global warming.
Therefore, air circulation behaves very different during temperature inversion process and poses hazardous effects on global climate.
Hope it helps! :)
