Answer: Bacteria will use the oxidised form of sulphur. Among all the forms of sulphur molecule such as sulphate which is the more oxidised form and also the other forms like thiosulphate,elemental sulphur, sulphite, hyposulphite can be used as an electron acceptor. As the coupling of these organic compounds occur, these sulfur bacterias obtain energy from the subsequent oxidation and then reduction of sulfur forms from sulphate to sulphide which is then released in the environment.
Answer:
red will be the bottom layer
Explanation:
in order to find its density you have to do mass/volume.
Blue: 12/3 = 3
Clear: 10/5= 2
Red: 15/3= 5
Yellow: 18/9 = 2
The one with the greates valua aka greatest density will be at the bottom layer/
Answer:
The options to this question are:
A) allele
B) codon
C) nucleotide
D) chromosome
The answer is A) allele
Explanation:
RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.
However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).
Answer:
True
Explanation:
Tobacco is consumed during smoking which contains an addictive substance called Nicotine. Nicotine exerts its effect on the body by stimulating the acetylcholine receptors in the neurons. The stimulation of these receptors stimulates another neurotransmitter like glutamate, dopamine and GABA which produce addictive effects in humans.
Since the acetylcholine is involved in stimulating the other neurotransmitters therefore true is the correct answer.
Thus, true is the correct answer.
