Answer:
The answer is covalent bonds
Explanation:
this population?
A. 300 - 1000 = 0.3
B. 1000 + 300 = 1300
C. 1000 x 0.3 = 300
D. 1000 - 300 = 3.33
The birth rate is defined as the number of births in a particular time divided by the total population. So the correct option is A.
A total number of births in a specific time (a year) divided by the total population (usually taken as 1000) is called the birthrate. The birth rate is calculated for various reasons.
Some of the things for which birth rate is needed are population count, universal registration of births etc.
Population growth is calculated using birth rate, mortality rate and migration rate from a population. The mid-year population is usually taken as the estimated population.
The birth rate is also referred to as natality. The rate of natural increase is given when the crude death rate is subtracted from the crude birth rate.
The birth rate of a population should be maintained at a moderate level by providing resources to people with children, creating awareness about methods of contraception etc.
The birth rate is calculated by dividing the number of births by the total population.
Therefore the correct option is A.

Answer:
Chemical spills, road salt, pesticides and fertilizers
Explanation:
Ground water pollution is addition of undesired substances to ground water that brings down its quality and makes suitable to be used by living beings. The chemical spills, road salt, pesticides and fertilizers get mixed with surface water and contaminate it. Percolation of contaminated surface water is the main cause of ground water pollution.

The transcription of DNA into a complementary strand of mRNA does not take place in translation.
In genetics and molecular biology, translation refers to the procedure in which ribosomes in the Endoplasmic reticulum or cytoplasm produce proteins after the procedure of transcription of DNA to RNA takes place in the nucleus of the cell.
In translation, the mRNA is deciphered in a ribosome to generate a particular chain of amino acid or polypeptide.
DNA transcription into a complementary strand of mRNA does not occur during translation process.
Keywords: Translation, messenger RNA, transcription, ribosomes.
