Answer:
10 times
Explanation:
Radiation weighing factor is a measure of the effectiveness of per unit dose of the given radiation that how much harmful it is for a biological tissue. In other terms it can also be defined as it is the ability of radiations to transfer the energy to the body.
For different particles it has different value. Some of the values are listed below -
Photons = 1
Electrons = 1
Protons = 2
Alpha particles, fission fragments, and heavy ions = 20
Neutrons = 2-20
Thus we can see that the value for alpha particles is 20 and for protons it is 2. Thus for alpha particles it is 10 times more than the protons.
Answer: peptide bonds
Explanation:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water.
This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Ans.1. False.
RNA or ribonucleic molecules are polymer of nucleotide molecules that perform various functions in a cell. rRNA is referred as ribosomal RNA and are involved in synthesis of ribosomes along with proteins. Ribosomes are described as molecular factory for protein synthesis, hence, rRNA plays an important role in protein synthesis.
Thus, given statement is false.
Ans.2.
Transcription is defined as a process, by which a parental DNA molecule gets transcribed into a RNA molecule with the help of RNA polymerase enzyme. The RNA molecule is then, translated into a specific polypeptide chain or protein.
According to central dogma of molecular biology, genetic information flows from a DNA molecule to a protein. During this, first step includes transcription (formation of RNA from DNA) and second step includes translation (formation of protein form RNA).
Thus, transcription plays an important role in the central dogma of molecular biology.
Water is considered a NATURAL resource (fresh water is also considered a limited resource)
oil, coal, and natural gas are considered NON-RENEWABLE resources.
CHEMICAL energy is able to be replaced within the ecosystem for human use.
a farmer who wants to produce the best crop yield will use PRECISION FARMING
when a pollutant increases in concentration at higher levels of the tropical level, BIOMAGNIFICATION can harm organismsat the highest levels.
