Mechanical stress applied to bone increases osteoblast activity in bone tissue, and the removal of mechanical stress decreases osteoblast activity.
Explanation:
Osteoblasts are cells , that are produced in the bone marrow and are responsible for formation of bones and bone matrix.
Whenever a mechanical stress is applied on the bones , a series of reactions are triggered. As a result the activities of osteoblast increases to synthesize more and more bone matrix to provide strength.
Again on the other hand a decrease in mechanical causes a decrease in the activities of the osteoblasts.
Answer:
Gamma-aminobutyric acid (GABA)
Explanation:
Gamma-aminobutyric acid (GABA) is the inhibitory neurotransmitter found in the central nervous system of mammals, especially humans, which is responsible for the regulation of communication between the brain cells, and also implicated in the slowing down of signals as neuronal impulses is reduced when it is activated. This is mostly responsible for the extreme uninhibited behaviors often associated with large alcohol consumption.
<span>Disparities in sentencing often occur due to factors such as race, gender, income, and social status. The judge's personal prejudices against certain cultural groups can sway a punishment to be more severe for some than others. Female tend to receive easier sentences than males. Wealthy seem to receive a slap on the wrist more often than the poor.</span>
The restriction endonuclease EcoRI cleaves the DNA sequence 5'-GAATTC-3' in such a way as to leave a 5' overhang, which is often referred to as a "sticky end". To 5' overhang with the complementary sequence this sticky end adhere.
- The palindrome EcoRI restriction site breaks DNA after G and creates sticky ends with AATT. G/corresponding AATTC's DNA sequence is CTTAA/G, where "/" designates the location of the peptide bond break.
- When the ssDNA sequence 5'-GAATTC'-3 is recognised by the restriction endonuclease EcoRI, a single-strand cut is made between the G and A nucleotides.
- At the ultimate end of double-stranded DNA, an overhang is single-stranded DNA. This can occur on either strand, and if it does, there will either be a 5' overhang on the 5' end of the strand or a 3' overhang on the 3' end of the strand.
