I’m his major contribution to know the full structure of DNA.
Answer:
the I bands to appear smaller
Explanation:
I band is the lighter and a less dense area of the sarcomere. It contains no thick filaments. A Z disc passes through the center of each I band. During muscle contraction myosin heads become attach to and slide along the thin filaments at both ends of a sarcomere. It pulls the thin filaments toward the M line and makes the thin filaments slide inward and meet at the center of a sarcomere. This inward movement of thin filament allows their ends to overlap.
As the thin filaments slide inward, I band and H zone narrower. I band and H zone become disappear altogether when the muscle is maximally contracted. The width of the A band and the lengths of the thick and thin filaments remain unchanged.
Answer: Option A) healthy fish populations.
Explanation:
Wetlands include swamps and marsh. i.e areas of land covered with water.
Once, wetlands are destroyed by human activities there would be:
- a reduction in the population of plant and animal that rely on its native organisms due to starvation.
- increased frequency of floods since excess water can no longer be collected there
- pollution of nearby streams as rain will wash off materials into them
However, healthy fish populations does not happen since producers like plankton eaten by the fishes are also destroyed.
Thus, healthy fish populations is the unlikely outcome
Answer:
The half-life (t1/2) is the time taken for the activity of a given amount of a radioactive substance to decay to half of its initial value. The mean lifetime (τ, “tau”) is the average lifetime of a radioactive particle before decay. The decay constant (λ, “lambda”) is the inverse of the mean lifetime
Atom in Latin is atomus which means the smallest particles
