By trapping heat, greenhouse gases contribute to our planet's warming. Because of its involvement in the Earth's carbon cycle and nitrogen cycle, the biosphere influences the amounts of some of the major greenhouse gases such as methane, carbon dioxide, and nitrous oxide.
Answer:
chemical weathering
In warmer climates, chemical weathering is more rapid because the chemical reactions that dissolve rocks and minerals are accelerated by warm temperatures.
Answer:
Secondary level of protein structure
Explanation:
The proteins are formed of the monomer units called amino acids which bond with each other via peptide bond and form a linear peptide structure called the primary level structure of the protein.
The proteins to perform several functions in a cell undergoes structural conformation and attain the helical form called alpha helix due to the involvement of alpha carbon in bond formation and a pleated sheet called beta-pleated sheet due to the involvement of beta carbon. These structures are known as a secondary level of protein structure.
Thus, a Secondary level of protein structure is the correct answer.
Answer:
constructing dams and building desalination plants help reduce the effects of droughts
Explanation:
Answer:
a. Genetic variation may be lost from the species as a whole
d. The overall adaptive prospects of the species may decline.
Explanation:
Genetic variations are heritable traits possess by the offspring from it progenitors. This makes the offspring to be an hybrid species because it has inherited the traits of both of his/her parents. In a local population setting goes to extinct, it might be as a result of genetic variation because these inherited variations comes in several ways, some might be adaptability to thrive in adverse weather conditions, some production of specific hormones to combat the current state that its not suitable for them etc. so when a population shows a decline in genetic variation, such population is liable to extinction.
Also, when species can't cope with factors attached with adaptation to a particular ecosystem, (such as exhibiting camouflage in time of danger, during dry season when food scarcity has increased etc) there will be decline in population of the species.
