Answer:
Vector changes with geography.
Explanation:
Vectors of disease are changing with the changing in the geographic location because different vectors survives in different environment so due to change in geography, vectors of a disease also change. Vectors refers to organisms that is responsible for carrying infectious bacteria or viruses that causes certain diseases in animals, plants and humans. Different vectors are present in different geography due to different climatic condition that forbit one vector to survive in all environments.

Answer:
its A
Explanation:
An autotroph or primary producer is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis). Autotrophs do not need a living source of carbon or energy and are the producers in a food chain, such as plants on land or algae in water (in contrast to heterotrophs as consumers of autotrophs or other heterotrophs). Autotrophs can reduce carbon dioxide to make organic compounds for biosynthesis and as stored chemical fuel. Most autotrophs use water as the reducing agent, but some can use other hydrogen compounds such as hydrogen sulfide. hope this helps :D
Answer:
The density of the substance is 2, 14 g/ml.
Explanation:
The density (δ) of a substance is the relationship between its mass and its volume. It is calculated in this way:
δ= m/v= 75 g/ 35 ml= <em>2, 14 g/ml</em>
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.
