Answer:
Resource conservation
Explanation:
Depresion in term of Resource conservation theory is a mental state where an individual or organism develops motivation to conserve a depleting resources while in search of a new source.
For a depressed organism to reduce energy consumption in order to save for the future, it is exhibiting resource conservation
4:
Independent Variable: Photosynthesis
Dependent Variable: Starch
Starch is a product of photosynthesis. Without photosynthesis, starch cannot form. Therefore starch is dependent on photosynthesis.
5:
Independent Variable: Temperature
Dependent Variable: Animal Metabolism
Animal metabolism will only be affected if the temperature of the room changes. Therefore animal metabolism is dependent on temperature.
9:
Independent Variable: Rainfall
Dependent Variable: Thickness of growth rings
The thickness of the tree's growth rings are determined by the amount of rainfall. Therefore the thickness of growth rings are dependent on rainfall.
Answer:
The circulatory system circulates the blood to the whole body.
The respiratory system brings oxygen to the blood, and the circulatory system circulates the oxygenated blood to the cells.
Explanation:
Answer:
In order to be useful in treating human infections, antibiotics must selectively target bacteria for eradication and not the cells of its human host. Indeed, modern antibiotics act either on processes that are unique to bacteria--such as the synthesis of cell walls or folic acid--or on bacterium-specific targets within processes that are common to both bacterium and human cells, including protein or DNA replication. Following are some examples.
Most bacteria produce a cell wall that is composed partly of a macromolecule called peptidoglycan, itself made up of amino sugars and short peptides. Human cells do not make or need peptidoglycan. Penicillin, one of the first antibiotics to be used widely, prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. The result is a very fragile cell wall that bursts, killing the bacterium. No harm comes to the human host because penicillin does not inhibit any biochemical process that goes on within us.
hope this helps :) can i get brainliest?
Explanation:
Remember the cell theory by Virchow that states that all cells come from pre existing cells, if a single cell dies, it can be replaced unless it's a brain cell.
