Answer:
This question lacks options, options are:
Chlamydiae
Planctomycetes
Rickettsia
Bacteroidetes
The correct answer is Chlamydiae.
Explanation:
Chlamydiae together with mycoplasmas, constitute the bacterial species with the smallest genomes, possibly because they are obligate small intracellular parasites for a long time, which has allowed them to lose certain metabolic pathways, however, they contain DNA, RNA and ribosomes therefore synthesize their own proteins and nucleic acids. Chlamydiae have a unique biphasic life cycle: the elemental body, which is the infectious form, and the reticular body, which is the replicative and metabolically active form that possesses a fragile membrane that lacks the extensive disulfide bonds characteristic of elemental bodies. The characteristics of its biological cycle do not facilitate the possibility of exchange and acquisition of exogenous genetic material.
Answer:
Explanation:
ATCG are called the Nitrogenous Base. The DNA(deoxyribonucleic acid) is made up of a phosphate group, 5 Carbon sugar called deoxyribose and Nitrogenous base.
This Nitrogenous bases are further divided into purine and pyrimidine
Purine includes- Adenine and Guanine while pyrimidine includes Thymine and Cytosine or Uracil in the RNA.
When Base pair occurs, Adenine pairs with Thymine while Guanine pairs up with cytosine in DNA.
The answer is atrial depolarization. The P wave of a normal electrocardiogram specifies atrial depolarization. In addition, depolarization happens in the four compartments of the heart which is both atria first and in both ventricles. The sinoatrial or as called as SA node on the wall of the right atrium starts depolarization in the right and left atria that can cause the contraction in which it is symbolized by the P wave on an electrocardiogram.
The dirt and fragments decompose and give the plant proteins/nutrients. Soil also anchors roots down and provides some water
