Answer:
The correct option is : c. gas gangrene
Explanation:
Gas gangrene is a serious bacterial infection caused by the infection of the Clostridium perfringens bacteria. This bacteria is always present in the nature and is a rod-shaped, gram-positive bacteria, that belongs to the Clostridium genus.
This disease can cause gas production in gangrene, death of the muscle tissues and also sepsis.
<u>Therefore, Gas gangrene is most associated with the bacteria Clostridium perfringens.</u>
M. DNA double helix
N. messenger RNA (mRNA)
O. DNA transcription (making mRNA)
P. an Amino Acid
Q. transfer RNA (tRNA)
R. a Ribosome
X. a Codon of post-splicing mRNA
Z. a Codon of pre-splicing mRNA (pre-mRNA)
Answer:
CH3 + 2O2-----> CO2+2H2O
Na+ + Cl- ------> NaCl
4Al + 3O2------> 2Al2O3
N2+ +3H2 ------> 2NH3

Answer:
1/4 or 1/2 depending on mating partner of F2
Explanation:
Assuming that the F1 parent Rr mated with a plant with the RR, Rr or rr genotype the F2 offspring would have the following genotypes:
Rr x RR= 1/2 RR, 1/2 Rr
Rr x Rr = 1/4 RR, 1/2 Rr, 1/4 rr
Rr x rr = 1/2 Rr, 1/2 rr
The F2 generation with the RR genotype could not be the parents of the F3 generation because to have individuals with the rr genotype the F2 generation would have to mate with a plant that is either Rr or rr in which case the fraction of the population with the stripe rust phenotype will either be 1/4 or 1/2, respectively.
When describing a community, biologist would discuss every population that lives in that area.
