Answer:
Combined decrease in sarcomere length.
Explanation:
Sarcomere is the functional unit of the striated muscle tissue. The units get repeated between the two Z lines. The striation under the microscope is shown by the sarcomere.
Actin and myosin protein plays an important role in the muscle contraction. The individual length of the thick (myosin) and thin (actin) filament do not changes and slide over one other. But the sarcomere overall length decreases that result in muscle contraction.
Thus, the answer is combined decrease in sarcomere length.
The answer is ‘the only truly distinctive primate trait’. Prehensile hands are a distinctive trait of primates an opposable thumb (capable of grasping). The digits have nails instead of claws, and tactile pads enriched with sensory nerve fibers at the ends of digits to feel to manipulate objects.
The single type of bacteria is not adequate to make any conclusions.
Answer:
They are used to transport electron during metabolic reaction.
To detect immunoglobulin m (IgM)antibodies in an acute phase, blood should be collected 7 days after the onset of infection.
- IgM and IgG antibodies to SARS-CoV-2 may both be found shortly after infection. IgG is typically detectable for extended periods of time, but IgM is most effective for diagnosing recent infection and typically becomes undetectable weeks to months after infection.
- IgM antibody detection is frequently viewed as a sign of an acute infection. Due to cross-reactivity with IgM antibodies to other, closely related bacteria or other interfering chemicals, false-positive IgM findings are, nonetheless, frequently observed.
- A positive IgM result may not always indicate an "acute" infection, and additional testing (such as IgG testing) may be required to interpret results because IgM antibodies may be detectable for 2-4 months (or longer) after disease resolution.
- For many infections, the onset of a measurable antibody response is 5-7 days after the infection. If samples are taken before infection, the initial IgM test results may be negative. Antibody production Immunosuppressed patients may also continue to be seronegative.
