Answer:
The hydrosphere
Explanation:
The atmosphere interacts with the hydrosphere to redistribute water over the surface of Earth.
Answer:
nuclear energy
Explanation:
An atom has a nucleus (or core) containing protons and neutrons, which is surrounded by electrons. Protons carry a positive electrical charge, and electrons carry a negative electrical charge. Neutrons do not have an electrical charge.
Answer:
false
Explanation:
On March 24, 1882, Dr. Robert Koch announced the discovery of Mycobacterium tuberculosis, not 1876
Answer:
Structure: unicellular organisms (single-celled), no nucleus or membrane-bound organelles, genetic material usually composed of a single circular bacterial chromosome coiled up in a region of the cytoplasm
Function: metabolic functions are carried out in the bacterial cytoplasm
Replication: generally asexual (binary fission)
Explanation:
Bacteria are prokaryotic organisms, i.e., unicellular organisms that do not have a cell nucleus nor any membrane-bound organelles
. Generally, the genetic material is composed of a single DNA circular molecule (bacterial chromosome), which is localized in a specific region of the cytoplasm (nucleoid region). Prokaryotic cells are usually smaller than eukaryotic cells (0.1 - 5 μm in size). In bacteria, metabolic functions (i.e., growth and reproduction) occur in the cytoplasm. The most important process of reproduction in bacteria is binary fission, a form of asexual reproduction where a single bacterial cell divides into two. Bacteria can also exchange genetic material by sexual reproduction mechanisms (i.e., conjugation, transformation and transduction). The main strategy to prevent outbreaks caused by bacteria is to know the conditions where they grow and reproduce. For example, <em>Salmonella</em> is a genus of infectious bacteria that may cause an outbreak. <em>Salmonella</em> infection may be prevented by eliminating conditions where they can multiply. Measures to prevent <em>Salmonella</em> outbreaks include cook food thoroughly (do not eat raw eggs or raw beef), refrigerate foods, wash hands, etc.
For question 1:
Look at the graph. In the beginning we start out with a feed of 75% wheat and 25% corn. The weight of the pig is 40. Look at the rest of the graph. Each time they lessen the amount of wheat the pigs eat and add more corn, they get heavier. By the end, the pigs are fed a blend of 25% wheat and 75% corn and they weigh 61 pounds. The answer would be C.
