Answer:
The geosphere transfers carbon to the biosphere when volcanic eruptions occur. Burning fuels like carbon dioxide, fossils, gasoline also transfers carbon from the geosphere to the biosphere.
Carbon is incorporated into the geosphere when an organism dies. The carbon then forms fossils fuels etc. which are consumed by humans. The shells becoming limestone also transfers carbon. These limestones are used by humans for various purposes.
Answer:
C. A phosphate group from ATP is added to a transport protein, changing its shape and facilitating transport.
Explanation:
ATP hydrolysis drives the active transport of substances through membrane proteins. During the process, the released phosphate group from ATP is added to the nucleotide-binding site present on the membrane protein to trigger a conformational change in it.
For example, the binding of a phosphate group from ATP to the nucleotide-binding site of NA-K+ ATPase brings about a conformational change in the protein. The phosphorylates pump has more affinity for K+ and lower affinity for Na+. It facilitates the release of bound Na+ from one side of the membrane to another.
If there are not to many leaves on the trees not too many birds will build a nest in it because the tree is not shaded and the birds will get hot and will not want the small birds to over heat and die.
Answer:
Decrease
Explanation:
Gene expression, which involves the production of useful gene products, occurs in two stages: transcription and translation. Transcription synthesizes a mRNA transcript by copying the information in the nucleotide sequence of a DNA. This mRNA sequence is then read during translation to synthesize amino acids (proteins) in a process called translation.
Translation is initiated when a transfer RNA (tRNA) binds to the binding sequence of the mRNA in the ribosome. However, gene expression (translation) in bacteria are regulated by short non-coding nucleotide sequences called small RNA or sRNA. sRNA's are regulators that inhibits translation by binding to the initiation site on the mRNA molecule, thus preventing the binding of the tRNA for translation to proceed.
If a sRNA binds to the binding site of a mRNA coding for an enzyme, it means the rate at which the enzyme (protein) will be produced will be low or not at all. Hence, there will be a decrease in the synthesis of that particular enzyme.
