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.
So we can easily classify animals and distinguish their relationships
Answer:
peptide and protein hormone
Explanation:
Peptide and protein hormones are composed of amino acids with latter being longer in length. They are synthesized in rough endoplasmic reticulum where they undergo various modifications like N terminal signal sequence removal and glycosylation to form prohormones. These prohormones are sent to golgi apparatus where they are packaged in secretory vesicles. In response to a stimulus the appropriate vesicle is released via exocytosis.
They can show regulated secretion where the hormone is stored in vesicles for a long time and then released in large amount in bursts for a proper stimulus. Sometimes they also show constitutive secretion where they are released slowly and steadily by the vesicles.
Answer:
Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. Most of the energy that passes through the upper atmosphere and reaches Earth's surface is in two forms, visible and infrared light.
