Pollution is the introduction of contaminants into the natural
environment that cause adverse change. Pollution can take the form of
chemical substances or energy, such as noise, heat or light. Pollutants,
the components of pollution, can be either foreign substances/energies
or naturally occurring contaminants. Pollution is often classed as point
source or nonpoint source pollution.
Hope this helps :p
Answer:
Explanation: When you have a slow digestive system, a condition known as gastroparesis or delayed stomach emptying, these muscles don't work properly. They either contact too slowly or don't work at all and, as a result, your stomach doesn't empty properly.
Eating slowly also helps our digestion. Think of digestion as a chain reaction. As soon as we see, smell, or think about food (step 1), we start salivating to prepare for putting that food in our mouth (step 2). Saliva contains enzymes that break the food down, and moistens the mouth for easier swallowing.
Answer:
chromosomes
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
The complex structures of deoxyribonucleic acid (DNA) and protein found in the cell nucleus are generally referred to as chromosomes.
In sexual reproduction, the chromosomes from parents are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.
Basically, the human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.
Answer:
Jet streams are very important during the weather prediction and other related aspects.
Explanation:
- Jet streams are important because they have the greatest aid in determining weather patterns all around the world.
- Meteorologists get help from jet streams to forecast weather by their position examination.
- They also carry great importance in air travel because flying in or out of them can greatly decrease the time of travel in air and fuel usage too.
- Separation of colder air from warmer air is done by the jet streams.
