Placental mammal is the answer.
The answer is tsetse fly.
African sleeping sickness is a disease caused by Trypanozoma brucei, a species of protozoa. The protozoic parasite is transmitted by a tsetse fly. When the tsetse fly bites the host, parasites enter the lymphatic system and then bloodstream. The first symptoms are itchiness, fever, headaches, and later the sleeping problems occur. The disease can even include dysfunction in cardiac, endocrine, or excretory systems.
Answer:
Archaebacteria have cell wall made of complex composition of peptidoglycan
Answer:
tertiary; quaternary
Explanation:
The orientation of all the atoms of a protein in three dimensions represents its tertiary structure. It includes the folding of the polypeptide chains in a way that brings are far apart amino acids of its secondary structure close together. Various segments of a polypeptide chain interact to form tertiary structures and these segments are held together by different kinds of weak interactions.
However, disulfide cross-links between the segments of polypeptide chains also stabilize the tertiary structure of some proteins. Likewise, disulfide bonds also hold the protein subunits of some proteins together and thereby, contribute to the quaternary structure. For example, two light chains of an antibody are joined together by disulfide bonds.
<span>Forensic investigators observe the crime scene and gather any physical evidence that is found and document the analysis done on them. Sketches and the photos taken at the crime scene are also the part of the evidence they collect. Since here the bloodstains found by the Forensic investigators are less than 1mm diameter, they can deduce the weapon used for crime would be shotgun as it has a narrow barrel.</span>
