Answer:
Hydrogen Bonding. A hydrogen bond is a weak type of force that forms a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons

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:
Answer:
C, Both parents have the blue-eyed gene.
The pancreas detects that the blood sugar level is higher and releases insulin. It tells the liver to store glucose in the blood as glycogen.
This regulates the blood sugar levels
Fungi are different from plants because fungi do not photosynthesize and plants do. FUngi do not have chlorophyll, but plants do. The fungi absorb nutrients from organic wastes due to decomposition process without light. Plants absorb nutrients from organic matter and transform them into food through photosynthesis process.
