Answer:
the hydrological cycle
Explanation:
The hydrological cycle is the cycle of the water between the Earth's surface (geosphere and biosphere) and the atmosphere. The water moves continuously between these spheres, making it one of the numerous agents that are interchanged and connect them. This cycle is one of the most important ones on Earth, as it is the one that enables life, precipitation, erosion, the existence of large bodies of water, rivers, and streams, the process of photosynthesis etc.
Answer:
A. Sensitive sense of smell.
Explanation:
Specific adaptation is the responsive biological adjustment to stress. Muscle, bone, heart, lung, vasculature, tendons, ligaments, joint cartilage, etc, are all affected by stress, but the nose doesn't change with stress.
The outcome of DNA replication is two DNA molecules consisting of one new chain and one old chain of nucleotides. This why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, and half is brand new.
DNA replication is the copying of DNA within the nucleus of the cell so that two full copies are present. This occurs before a cell divides. Two copies of a cell's DNA need to be present before the cell divides so that each of the resulting daughter cells will have one full copy of the parent cell DNA.
Answer:
Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, this was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose B) allosteric regulation of the repressor
Explanation:
When we talk about the mechanisms of enzyme regulation, we refer to allosteric regulation of the repressor. The Allosteric control of transcriptional regulatory proteins allows organisms to react to changes in environmental and metabolic conditions. Also, it is s a thermodynamic phenomenon. When it binds one molecule, the affinity with which a protein binds to a second molecule is altered.
